Key takeaways
- 1Femoroacetabular impingement means the ball of the thigh bone and the hip socket do not fit together smoothly, so they collide at the end of certain movements.
- 2The two main shapes are cam (an extra bump on the ball) and pincer (a socket that covers too much of the ball), and many people have a mix of both.
- 3Typical symptoms are deep groin pain after sitting, squatting or pivoting, often with a catching feeling and a reduced range of hip rotation.
- 4A careful exam, a standing pelvis X-ray and an MRI or MR arthrogram usually confirm femoroacetabular impingement, but imaging must always be matched to symptoms.
- 5Many people with an impingement-shaped hip never have pain, so a scan finding alone is not a reason for surgery.
- 6A structured physiotherapy programme of at least 3 months is a sensible first step for most patients with femoroacetabular impingement.
- 7Hip arthroscopy reshapes the bone and repairs the labrum, and treatment of femoroacetabular impingement in turkey can suit planned, non-urgent cases after a records review.
Overview
What is femoroacetabular impingement?
Femoroacetabular impingement is a mismatch between the shape of the ball (femoral head) and the socket (acetabulum) of the hip. When the hip bends or rotates, the two surfaces bump into each other early and pinch the soft tissue between them. This page covers the shapes, symptoms, tests, care options and treatment in turkey.
What is femoroacetabular impingement?
Femoroacetabular impingement, often shortened to FAI, is a shape problem rather than a wear problem. People often type FAI hip pain into a search box when the first groin ache appears. The word "femoro" refers to the thigh bone, and "acetabular" refers to the socket in the pelvis. "Impingement" simply means that two structures pinch or crowd one another.
In a healthy hip the ball glides inside the socket through a wide arc. With femoroacetabular impingement, a bony bump or an over-deep socket stops the glide too soon. The ring of cartilage around the socket rim, called the labrum, takes the stress and can fray or tear.
Who gets femoroacetabular impingement?
Femoroacetabular impingement is usually noticed in active adults between roughly 20 and 50 years of age. It is seen in both sexes, although the cam shape is reported more often in men and the pincer shape more often in women. Footballers, hockey players, dancers, martial artists and people whose work involves deep squatting come to clinic often.
The bone shape is thought to develop in adolescence, while the growth plates are still open. Heavy, repeated sport in those years may play a part, and some people simply inherit a hip with this shape.
How serious is femoroacetabular impingement?
For most people femoroacetabular impingement is a nuisance that limits sport and long sitting, not a danger to health. The concern is long-term. A hip that keeps colliding may slowly lose cartilage, and some researchers link untreated impingement shapes to earlier hip arthritis. The link is real but not certain for every person, which is why decisions are made case by case.
The sections below follow the order of a clinic visit: anatomy, types, diagnosis, look-alike conditions, non-surgical care, surgery, treatment abroad, risks and outlook.
Anatomy
What happens in the body with femoroacetabular impingement
The hip is a ball-and-socket joint built for both stability and a large range of movement. Understanding the parts makes the pinching in femoroacetabular impingement much easier to picture.
What does a normal hip look like?
The ball is the rounded top of the thigh bone. Just below it sits a narrower section called the femoral neck, and the junction between the round head and the neck should have a smooth, waisted curve. The socket is a cup in the pelvis that wraps around about half of the ball.
Both bone surfaces are covered with articular cartilage, a glassy layer about 2 to 4 mm thick that lets the joint glide. Around the socket edge lies the labrum, a rim of tough fibrocartilage that deepens the cup and helps seal fluid inside the joint.
- Capsule and ligaments: a strong sleeve that holds the ball in the cup.
- Muscles: the gluteals, iliopsoas (the main hip flexor) and deep rotators move and steady the joint.
- Synovium: a thin lining that makes lubricating fluid.
What changes in femoroacetabular impingement?
In the cam pattern the waist of the head-neck junction is filled in by an extra bump of bone, so the ball is not perfectly round. When the knee is pulled towards the chest, this bump rides into the socket edge and shears the cartilage from the bone.
In the pincer pattern the socket is too deep, tilted back or reaches too far forward. The rim crushes the neck of the femur and pinches the labrum between the two bones. Over time the labrum can tear, small cysts can form, and the cartilage next to the damaged rim can soften.
Symptoms & causes
Femoroacetabular impingement symptoms and causes
Common symptoms
- Deep groin pain that is felt on the front or side of the hip, often described by patients as a "C" shape held round the upper thigh (the "C sign").
- Pain after prolonged sitting, for example 30 to 60 minutes in a car, at a desk or in a cinema seat, which eases once you stand and walk about.
- Pain on deep flexion movements such as squatting, putting on socks and shoes, getting out of a low sofa, or bringing the knee to the chest.
- A sharp pinch when the hip pivots or twists, for instance turning to kick a ball or stepping sideways out of a car.
- Stiffness and a feeling that the hip "blocks" before it reaches its normal range, particularly when rotating the thigh inwards.
- Clicking, catching or a momentary lock in the hip, which may suggest that the labrum has become damaged or frayed.
- Pain that spreads to the outer hip, the buttock, the front of the thigh or the lower back, because several structures share nerve supply.
- A dull ache after sport that can last for hours or the next morning, even though the activity itself felt fine at the time.
- Reduced sporting performance, such as a shorter stride, less hip drive in sprinting or difficulty with deep lunges and kicks.
- Mild limping or protective stiffness after long walks when the hip has been irritated for months.
Causes and risk factors
- Cam morphology: an extra bump at the head-neck junction of the femur, probably formed while the growth plate was still active in adolescence.
- Pincer morphology: a socket that is too deep or over-covers the ball, sometimes because the socket points backwards (retroversion).
- Combined shape: many patients show both cam and pincer features, so the two mechanisms add to one another.
- Heavy, high-impact sport during growth, particularly football, ice hockey and martial arts, which seems to be linked with a larger cam bump.
- Family tendency: relatives often share similar hip shapes, though no single gene explains femoroacetabular impingement.
- Childhood hip conditions such as slipped capital femoral epiphysis or Perthes disease, which can leave the ball with an altered shape.
- Previous hip injury or a poorly aligned fracture of the neck of the femur, which may change how the ball sits.
- Repetitive end-range movement, for example in dance or gymnastics, which can aggravate an already tight hip and turn a silent shape into a painful one.
Types
Types and stages of femoroacetabular impingement
Doctors classify femoroacetabular impingement mainly by the bone shape, because the shape guides how surgery is planned. A short summary of each pattern follows, then a comparison table.
What is cam impingement?
Cam impingement involves the femoral head and neck. The head is slightly egg-shaped, so as the hip flexes the bump is levered into the socket. Cam impingement damages the cartilage on the socket edge, typically at the upper front part, and the pain tends to come with deep bending.
What is pincer impingement?
Pincer impingement is a problem of the socket. The rim projects too far or sits too deep, so it traps the labrum against the neck of the femur. Because the damage falls on the labrum first, the pain can feel sharper and the labrum may calcify or ossify over the years.
What is mixed impingement?
Mixed impingement is the most frequent pattern in surgical series. It combines a cam bump with a deep or over-covering socket, and both need to be corrected for a good result.
| Type | Where the problem is | What it does | Typical imaging clue |
|---|---|---|---|
| Cam | Head-neck junction of the femur | Bump jams into the socket and shears cartilage | Loss of the waist; raised alpha angle |
| Pincer | Socket rim | Rim crushes the labrum against the neck | Crossover sign; deep socket; raised centre-edge angle |
| Mixed | Both ball and socket | Both mechanisms act together | Features of cam and pincer on the same hip |
How is the severity judged?
Surgeons also record the state of the cartilage using systems such as the Tonnis grade, which runs from 0 (normal) to 3 (advanced arthritis). A grade of 0 or 1 usually means a hip that can be preserved. By grade 2 or 3, shape correction is less likely to help, and the discussion often changes towards arthritis care.
Diagnosis
How is femoroacetabular impingement diagnosed?
Femoroacetabular impingement is diagnosed by combining three things: your story, an examination and imaging that fits both. None of them is enough alone, because many hips without symptoms look impingement-shaped on a scan.
What will the doctor ask?
The clinician will ask where the pain sits, which movements trigger it and how long you can sit before it flares. They also ask about childhood hip problems, sport history, previous injuries and what you have already tried. A pain diagram and a short list of the activities you want to return to are very helpful.
What does the examination include?
The hip is moved through its range while you lie on your back. The most known manoeuvre is the flexion, adduction and internal rotation (FADIR) test, which brings the knee up and across the body, then turns the thigh inwards. Pain in the groin on this movement suggests impingement, though it is not specific.
The doctor will also check internal rotation at 90 degrees of flexion, the strength of the hip flexors and abductors, walking pattern, spine movement and the pelvis. They look for general joint laxity, because a very flexible hip needs a different plan.
Which imaging is used?
Plain X-rays are the first step. A standing front view of the pelvis and a lateral view of the hip (such as a Dunn or cross-table view) show the shape of the head-neck junction and the depth of the socket. Doctors measure the alpha angle for cam shape and the lateral centre-edge angle for socket coverage.
An MRI, often with contrast fluid injected into the joint (MR arthrogram), shows the labrum and cartilage. A CT scan with 3D reconstruction may be ordered when surgery is planned, to map exactly how much bone should be removed.
What should you send for a remote review?
For an online case review, gather the X-ray images in DICOM format (not just the report), any MRI discs, a short symptom timeline and a list of past treatments. Add the dates of any injections and the name of your current physiotherapy plan. You can start a free review through our case review form, and the medical record review guide explains the process.
Tests you may have
- Standing anteroposterior (AP) pelvis X-ray: shows socket depth, rim position and signs of the crossover sign, with both hips compared side by side.
- Lateral hip X-ray (Dunn 45 or cross-table): shows the head-neck junction from the side, where the cam bump is easiest to see.
- Alpha angle measurement: an angle on X-ray or MRI that quantifies the roundness of the ball; values above roughly 55 degrees are often taken as suggestive of a cam shape.
- MRI or MR arthrogram: shows labral tears, cartilage thinning, cysts at the rim and any surrounding soft-tissue problem.
- CT scan with 3D reconstruction: maps the exact position and size of the bone bump and the version of the socket for surgical planning.
- Diagnostic hip injection: local anaesthetic placed in the joint under ultrasound or X-ray guidance, where relief of pain suggests the source is inside the hip.
- Clinical range of motion and impingement tests: measured with a goniometer and the FADIR test to link symptoms to the movement.
Look-alikes
Conditions that can feel like femoroacetabular impingement
Groin and hip pain has many sources, so femoroacetabular impingement must be separated from look-alike problems. The table below shows how doctors tell them apart.
| Condition | How it differs | How doctors tell |
|---|---|---|
| Hip labral tear | A torn rim of cartilage; often a result of impingement rather than a separate cause | MR arthrogram shows the tear; symptoms include catching and locking |
| Hip osteoarthritis | Joint space is narrowed and bone spurs are visible; morning stiffness is common | Standing X-rays show loss of joint space |
| Hip bursitis | Pain on the outer point of the hip, worse lying on that side | Tender spot over the greater trochanter; imaging of the joint is normal |
| Hip dysplasia | A shallow socket that under-covers the ball, the opposite of a deep pincer socket | Low centre-edge angle on the pelvis X-ray |
| Sports hernia or adductor strain | Pain in the lower abdomen or inner thigh, provoked by resisted adduction | Tenderness at the pubic bone; a normal hip exam |
| Lumbar spine referral | Back pain with leg symptoms; hip movement is often comfortable | Spine exam, nerve tests and lumbar MRI |
Why does the distinction matter?
Treating a muscle or spine problem with hip surgery will not help. Likewise, a shallow, unstable hip with a loose capsule can get worse if too much tissue is removed. A careful differential protects you from an operation that does not match the cause of the pain.
Can more than one problem coexist?
Yes. Many athletes have femoroacetabular impingement together with a groin muscle problem, and many people with impingement also have lower-back stiffness. A good clinic will list each contributor and rank them, so that rehabilitation addresses the whole picture and not only the joint.
Non-surgical
Non-surgical treatment for femoroacetabular impingement
Most people with femoroacetabular impingement are offered non-surgical care first, because it carries little risk and can settle symptoms even though it cannot change the bone shape. Reasonable care usually lasts 3 to 6 months before surgery is discussed.
Step 1: Modify the activities that provoke pain
The first move is to reduce the positions that pinch the hip. That means avoiding very deep squats, low seats, repeated pivoting and long periods of sitting with the hips bent beyond 90 degrees. This is not about stopping exercise. Cycling with a higher saddle, swimming with a flutter kick and walking on level ground are usually tolerated.
Step 2: Physiotherapy built around the hip and the trunk
A physiotherapist will assess the strength of the gluteal muscles, the deep rotators and the abdominal core, then design a progressive plan. The aim is to improve control so that the pelvis does not tilt forward at the end of movement and push the hip into the pinch position.
Studies comparing physiotherapy with arthroscopic surgery in femoroacetabular impingement suggest that both can reduce pain over 1 to 2 years, with surgery tending to give a larger gain in some trials. Rehabilitation helps many people avoid an operation, and it is also a strong preparation for surgery should that become necessary.
Step 3: Medicines
Short courses of oral non-steroidal anti-inflammatory drugs (NSAIDs) may calm a flare for people who can safely take them. Paracetamol is a simple option for mild pain. Your doctor or pharmacist will advise on suitability, especially if you have stomach, kidney or heart conditions. Medicines ease symptoms but do not change the joint shape.
Step 4: Injections
An image-guided corticosteroid injection into the hip joint can reduce pain for several weeks and also helps to confirm that the joint is the source of symptoms. Repeated steroid injections are generally avoided, since they may weaken tissue over time and relief is short-lived.
What do the timelines look like?
| Phase | Approximate time | Main focus |
|---|---|---|
| Calm the hip | Weeks 0 to 3 | Activity changes, gentle range of movement, short-term pain relief |
| Build control | Weeks 3 to 12 | Gluteal and core strengthening, movement retraining |
| Return to sport | Months 3 to 6 | Sport-specific drills, graded loading, review of progress |
If the hip is clearly better by 3 months, many people continue the exercises and never need surgery. If pain still limits you after a full, supervised programme, it is time to talk about the next step.
Self-care
Exercises and self-care for femoroacetabular impingement
Good self-care for femoroacetabular impingement means keeping the hip moving within a comfortable range while avoiding the pinch positions. Please check with your doctor or physiotherapist before starting any exercise, particularly if pain is increasing.
Which hip impingement exercises are usually safe?
Hip impingement exercises generally favour strength and control over stretching deep into the painful corner. These examples are common in programmes, but your therapist may change them.
- Glute bridge: lie on your back with knees bent, lift the pelvis until the body forms a straight line, hold for 3 seconds, and repeat 10 to 15 times.
- Side-lying leg raise: lift the top leg about 30 cm with the toes pointing slightly down, 10 to 12 repetitions each side.
- Clamshell with a light band: keep the feet together and open the knees, without rolling the pelvis back.
- Dead bug: lie on your back and alternate lowering opposite arm and leg while the lower back stays flat.
- Short-range squat to a high box: stop well before the hip feels pinched, and keep the knees tracking over the second toe.
How should exercises progress?
Start with 2 sets, 3 or 4 days each week. Add repetitions first, then resistance. A mild ache of up to 3 out of 10 that settles within a day is usually acceptable. Sharp pinching pain, or a flare that lasts into the next day, means the load was too high and should be reduced.
What daily habits help?
- Sit on a slightly raised cushion so the hips stay above the knees.
- Stand up and walk for 2 or 3 minutes after each 30 to 45 minutes of sitting.
- Pick up objects by hinging at the hip with a neutral spine rather than squatting deeply.
- Sleep on your back, or on your side with a pillow between the knees.
- Keep body weight in a healthy range, which lowers the load on the joint with every step.
What should you avoid?
Avoid repeatedly forcing the knee towards the opposite shoulder, aggressive deep stretches of the hip and long runs on days when the hip is sore. Passive stretching of an already tight hip can irritate the labrum. Do not push through sharp pain, and stop if you notice numbness, a locking hip or night pain that is getting worse.
Check with your doctor or physiotherapist before starting new exercises, and stop any movement that causes sharp pain.
Treatment
Femoroacetabular impingement treatment options
Surgery for femoroacetabular impingement aims to remove the bone that collides and to protect or repair the labrum. It is usually done through keyhole surgery, and it is offered after non-surgical care has not given enough relief.
What is hip arthroscopy for femoroacetabular impingement?
Hip arthroscopy uses a camera and thin instruments through 2 or 3 small cuts, each roughly 1 cm. The surgeon works with gentle traction on the leg to open the joint. The cam bump is shaved with a burr (an osteoplasty), and an over-hanging socket rim can be trimmed (acetabuloplasty). The capsule is then closed or repaired to restore stability.
Operating time is often 1.5 to 2.5 hours, and many people go home the same or next day. You can read how the operation is organised in turkey on the hip arthroscopy in turkey page, and the hip arthroscopy cost guide explains what influences the cost.
What is hip labral repair?
When the labrum has torn, it is usually repaired by stitching it back to the bone with small suture anchors. In some hips the labrum is too damaged to hold stitches, and surgeons may consider reconstruction with a graft. Learn more on the hip labral repair page, the hip labral repair in turkey page and the hip labral repair cost guide.
How do the options compare?
| Option | Best suited to | Trade-offs |
|---|---|---|
| Rehabilitation only | Mild to moderate symptoms; people who want to avoid surgery | Does not change bone shape; needs commitment for 3 months or more |
| Arthroscopic reshaping | Active adults with a clear cam or pincer and a joint that still has good cartilage | Several months of rehabilitation; small risk of nerve irritation or stiffness |
| Arthroscopy with labral repair | A torn labrum with stable tissue | Protected loading for 4 to 6 weeks after surgery |
| Open or mini-open correction | Complex deformity not reachable by keyhole surgery | Larger cut and longer recovery |
| Hip replacement | Advanced arthritis, not simple impingement | A major operation, reserved for worn-out hips |
What does the recovery look like?
After hip arthroscopy, you may use crutches for 2 to 6 weeks, depending on whether a repair was done. Physiotherapy starts early with gentle range of movement. Walking comfortably often returns by 6 weeks, jogging at about 3 to 4 months, and a full return to cutting sports commonly takes 4 to 6 months or longer.
When surgery is considered
Surgery for femoroacetabular impingement is worth considering when pain and stiffness continue to limit daily life or sport after a genuine, supervised trial of rehabilitation, and when scans match your symptoms. Not every impingement-shaped hip needs an operation.
What criteria do surgeons look for?
- Persistent groin pain that reproduces on the impingement test and matches the area you point to.
- At least 3 months of properly guided physiotherapy and activity changes without enough benefit.
- Imaging that shows a cam or pincer shape, with or without a labral tear.
- Cartilage that is still in reasonable condition, usually Tonnis grade 0 or 1.
- Clear goals, such as returning to football, dancing or heavy manual work.
Who may not benefit?
People with significant joint-space loss, widespread arthritis or very limited range of motion often do less well after reshaping. Those with a generally lax hip, a shallow socket or hip dysplasia can be made worse if too much capsule or rim is removed. In these cases a different plan is safer.
What can you ask your surgeon?
- Which exact shape do I have, and how much bone will be removed?
- What is the state of my cartilage, and how does it change my chances?
- Will the labrum be repaired, and how long will I be on crutches?
- How many hip arthroscopies do you perform each year?
- What is your plan if the pain does not improve?

In Turkey
Treating femoroacetabular impingement in Turkey
Treatment of femoroacetabular impingement in turkey can make sense for planned, non-urgent surgery when your diagnosis is clear and your records have been reviewed by the treating team. It is not a route for emergencies, and your own doctors remain part of the plan.
Why do patients consider femoroacetabular impingement surgery in turkey?
Femoroacetabular impingement treatment in turkey is usually planned around keyhole surgery, and hip arthroscopy for femoroacetabular impingement in turkey is offered by many private orthopedic teams.
Some patients face long waiting lists for hip arthroscopy at home, and some want a surgeon who performs the operation often. Turkey has a large private orthopedic sector, with centres in Istanbul, Ankara, Izmir and Antalya. Our turkey orthopedics overview explains how care is organised, and the why turkey guide sets out the reasons patients choose it.
What does the pathway look like?
- Records review: you send X-rays, MRI images and a short history through the free case review.
- Surgical opinion: a specialist team confirms whether your shape and cartilage suit surgery and outlines the plan.
- Travel and admission: you arrive a few days before surgery for tests and a consultation.
- Surgery: hip arthroscopy, often with labral repair, under general or regional anaesthesia.
- Early rehabilitation: supervised physiotherapy starts in the first days, and you stay long enough for wound review.
- Follow-up at home: your own physiotherapist continues the plan, with scheduled video check-ins.
What should you send and check?
Share the actual image files, the radiology reports, a summary of non-surgical care and your list of medicines and allergies. Ask about the hospital's accreditation, the surgeon's training in hip preservation and how many hip arthroscopies they perform. Request a written plan that names the procedures planned and the rehabilitation protocol. The hospital admission guide and the surgery day guide describe what to expect.
How should you plan the trip?
Most people allow roughly 7 to 10 days away for hip arthroscopy, so that the early wound checks and first physiotherapy sessions happen before the flight home. Short flights are usually acceptable in the first days, though you should follow the surgeon's advice on blood clot prevention. The flying after surgery guide, the travel and accommodation guide and the companion guide help with planning.
When is it better not to travel?
Travel is not advised if the hip has advanced arthritis that needs a different operation, if you have an active infection, uncontrolled heart or lung disease, or a recent blood clot. It is also unwise to go abroad if you cannot arrange rehabilitation at home afterwards. Aftercare matters as much as the operation, and the rehabilitation guide and follow-up guide explain how to arrange it. Rough costs are explained in the cost guides linked above, and nothing replaces a personal quote.
Complications
Complications of femoroacetabular impingement
Femoroacetabular impingement is not dangerous to life, yet leaving it alone and having surgery both carry possible downsides. Knowing them helps you weigh the decision calmly.
What can happen if it is not treated?
Repeated pinching may tear the labrum, thin the cartilage and create rim cysts. Some studies link a larger cam bump with a higher chance of hip osteoarthritis in later life, but many people with the same shape never develop it. Activity that hurts is often reduced, which can lead to weaker muscles and a less fit body.
What are the risks of hip arthroscopy?
Hip arthroscopy is generally considered safe, and serious problems are uncommon. The possible risks include:
- Temporary numbness around the groin or thigh from traction on nerves, which usually settles within days to weeks.
- Stiffness or scar tissue (adhesions) that may need extra physiotherapy or, rarely, a second keyhole procedure.
- Persistent pain or incomplete bone correction, which can lead to revision surgery in a small proportion of patients.
- Infection, blood clots or bleeding, all uncommon, and reduced by sterile technique and clot prevention.
- Heterotopic ossification, where extra bone grows in soft tissue, which medicines are sometimes used to prevent.
- Fluid leaking into the tissues during the operation, which is monitored by the anaesthetic team.
How can the risk be lowered?
Choose an experienced hip surgeon, follow the rehabilitation plan, keep scheduled reviews and report fever, calf pain or a wound that looks red or leaks. Good pre-operative strength also reduces setbacks. Ask your surgeon to explain each risk in terms of your own hip, because individual chances depend on age, cartilage condition and the extent of the repair.
Urgent care
When to seek urgent care for femoroacetabular impingement
- Sudden severe hip pain after a fall or impact, with inability to put weight on the leg: go to an emergency department, because a fracture needs urgent care.
- Fever, chills and a hot, swollen, very painful hip, especially after surgery or an injection: seek same-day medical care for possible joint infection.
- A calf that is swollen, warm and tender, or sudden breathlessness after surgery: call emergency services, since a blood clot is possible.
- Numbness in the groin or saddle area, loss of bladder or bowel control, or new leg weakness: seek emergency help for possible nerve compression.
- A hip that locks and will not straighten or bend: arrange an urgent specialist review, as a loose fragment may be trapped.
- Night pain that wakes you repeatedly, or pain with unexplained weight loss: see your doctor promptly, because other causes must be excluded.
- A surgical wound that is spreading red, opening or draining fluid: contact your surgical team the same day.
Prevention
How to lower your risk of femoroacetabular impingement
You cannot completely prevent femoroacetabular impingement, because the bone shape is largely set during growth. You can, however, lower the chance that a quiet shape becomes a painful hip and slow down damage in a hip that is already affected.
What cannot be changed?
The curve of the femoral head and the depth of the socket come from genes and development. No stretch or supplement reshapes them. Regular screening of hips without symptoms is not recommended, since an impingement shape on a scan does not predict pain in an individual.
What can reduce the risk of symptoms?
- Balanced training in youth: young athletes benefit from varied sport, adequate rest and good technique rather than a single repeated movement year-round.
- Strong hips and trunk: well-conditioned glutes and core muscles help to guide the pelvis, so the ball seats correctly during movement.
- Early attention to groin pain: a young player with persistent groin pain should be assessed rather than playing through it.
- Healthy weight: lowering excess body weight eases the force across the joint.
- Warm-up and mobility: a 10-minute warm-up before sport prepares the hip for end-range positions.
How can you protect the hip after treatment?
After surgery, follow the physiotherapy plan for the full time suggested, usually 4 to 6 months. Keep a strength programme going for the long term, and gradually restore sport rather than rushing back. Report new pain early, since it is easier to settle a flare in its first weeks.
Does staying active help or harm?
Moderate, regular movement is good for cartilage nutrition and muscle support. Avoid high-risk end-range activity when the hip is flared, but do not stop all exercise. Swimming, cycling and walking are common choices for keeping fit while the joint is irritated.
Outlook
Living with femoroacetabular impingement: outlook and recovery
The outlook for femoroacetabular impingement is generally good when it is recognised early and managed with a sensible plan. Many people return to the activities they enjoy, though the course varies and cartilage health is the strongest predictor.
What happens with rehabilitation alone?
A fair number of people settle with 3 to 6 months of rehabilitation and activity changes, especially if symptoms are mild and the shape is modest. Others get partial relief and learn to manage flares. The bone shape stays the same, so deep end-range positions may stay uncomfortable.
What happens after surgery?
Most studies of hip arthroscopy for femoroacetabular impingement report meaningful improvement in pain and function at 2 years in many patients, with return to sport in a majority of athletes. Results tend to be better when cartilage is healthy, the correction is complete and rehabilitation is well followed. Outcomes are less predictable in older patients or those with early arthritis.
When do people return to work and sport?
| Activity | Typical timing after arthroscopy |
|---|---|
| Desk work | 1 to 2 weeks, with breaks to stand |
| Driving | Roughly 2 to 4 weeks, once off crutches and not taking strong pain medicines |
| Manual work | 8 to 12 weeks, depending on the demands |
| Running | 3 to 4 months, in a graded plan |
| Contact or cutting sport | 4 to 6 months or more |
What about the long term?
Some patients later develop arthritis, particularly if cartilage was already worn at the time of surgery. If that happens, the options in the hip osteoarthritis pathway are available. For a wider look at the joint, visit our hip care hub. Regular strength work, a healthy weight and prompt review of new symptoms give the best chance of a hip that lasts.
