Hip Labral Tear & FAI Treatment Hawaii

Deep groin pain with sitting, squatting, pivoting, or bringing the knee toward the chest may come from the hip joint. Two findings often mentioned together are a hip labral tear and femoroacetabular impingement, usually shortened to FAI.

Those words can sound like a direct path to surgery. They are not.

Many people have a labral change or a cam- or pincer-shaped hip on imaging without pain. A meaningful diagnosis requires the symptoms, examination, and imaging to tell the same story. Treatment should also account for hip strength, movement control, activity goals, cartilage health, arthritis, and whether another problem is actually causing the pain.

Key takeaway: An MRI finding alone does not decide treatment. Physical therapy is often the first active treatment. Hip arthroscopy becomes a more reasonable discussion when symptoms remain limiting despite a well-designed nonsurgical program and the examination and imaging identify a correctable problem.

What are the labrum and femoroacetabular impingement?

The hip is a ball-and-socket joint. The femoral head is the ball, and the acetabulum is the socket. The labrum is a ring of fibrocartilage around the socket. It helps deepen the socket, distribute load, and maintain the seal that supports smooth joint motion.

A labral tear may occur after a twist or other injury, but many develop gradually. The tear can be associated with:

Cam morphology, where extra bone or loss of roundness at the femoral head-neck junction contacts the socket
Pincer morphology, where the socket covers the femoral head more than usual in a particular region
Hip dysplasia, where the socket does not provide enough coverage
Repetitive deep flexion and rotation
Joint laxity or instability
Cartilage damage or osteoarthritis
Prior trauma

FAI syndrome is a motion-related disorder in which symptoms, clinical signs, and imaging findings are present together. The Warwick Agreement international consensus specifically cautions against diagnosing the syndrome from bone shape alone.

That distinction matters. A person may have cam morphology on an X-ray but no symptoms. Another may have groin pain and a labral tear on MRI, but the main pain source is the lumbar spine, an abdominal-wall problem, an adductor injury, or advanced hip arthritis.

What does a symptomatic labral tear or FAI usually feel like?

The most common pattern is pain in the groin or front of the hip. Some people cup the hand around the front and side of the hip, sometimes called a “C-sign.”

Symptoms may include:

Groin pain during or after activity
Pain with deep squatting, lunging, or bringing the knee toward the chest
Discomfort getting out of a low chair or car
Pain after prolonged sitting
Symptoms with twisting, cutting, kicking, or changing direction
Stiffness or loss of hip rotation
A feeling of catching, clicking, or giving way
Reduced tolerance for running, lifting, surfing, martial arts, dance, or field and court sports

Clicking does not automatically mean the labrum is torn. Tendons can snap around the hip, and painless clicking is common. A labral tear can also cause pain without any click.

The pattern is more informative than one symptom. Deep joint pain reproduced by hip flexion and rotation raises suspicion, but it is not specific enough to diagnose the problem by itself.

When hip pain needs urgent attention

Most labral and impingement symptoms develop gradually and are not emergencies. Seek urgent medical care for:

Inability to bear weight after a fall or collision
A visibly deformed hip or leg
A hot, swollen joint with fever or rapidly worsening illness
Severe pain after trauma, especially with a shortened or rotated leg
New loss of leg strength or sensation
Loss of bladder or bowel control, saddle numbness, or other signs of severe nerve compression
Calf swelling, chest pain, or shortness of breath

These findings may represent fracture, dislocation, infection, a neurologic emergency, or a blood clot rather than an uncomplicated labral problem.

Why an MRI tear is not automatically the pain source

Labral abnormalities are found in people who do not have hip pain. In a study comparing symptomatic patients with matched asymptomatic volunteers, labral defects were reported in 44% of the volunteers. Cartilage and labral findings were more common in symptomatic patients, but the study demonstrates why imaging must be interpreted in context. Read the MRI study on PubMed.

The same principle applies to cam and pincer morphology. Bone shape may increase the chance of contact in certain positions, but shape alone is not a disease.

Before recommending treatment, an orthopedic evaluation should answer several questions:

Does the pain behave like pain from inside the hip joint?
Does the examination reproduce the person’s familiar symptoms?
Do the X-rays and MRI show a finding that matches the symptoms?
Is arthritis, dysplasia, instability, or cartilage loss present?
Could the pain be coming from the back, tendons, abdominal wall, pelvis, or another nearby structure?

How is a hip labral tear or FAI evaluated?

History and examination

A useful evaluation starts with the location, onset, and behavior of the pain. The clinician may ask about prior injury, sports and work demands, stiffness, clicking, instability, back symptoms, childhood hip conditions, and which positions reproduce the problem.

The examination may include:

Walking pattern and single-leg control
Hip range of motion, especially flexion and internal rotation
Strength of the hip abductors, rotators, and flexors
A flexion-adduction-internal-rotation, or FADIR, maneuver
Other provocative hip tests
Tenderness over the hip flexors, adductors, or lateral tendons
Lumbar spine and neurologic examination
Assessment for instability, dysplasia, or generalized joint laxity

A provocative test is useful when it reproduces the patient’s familiar pain, but no single maneuver proves that the labrum is the source.

X-rays

Standing pelvis and dedicated hip X-rays are usually the first imaging studies for persistent suspected FAI. They can show:

Cam or pincer morphology
Joint-space loss and arthritis
Hip dysplasia or undercoverage
Prior fracture or deformity
Other bone abnormalities

X-rays do not show the labrum directly, but they provide essential context. A labral tear in a well-preserved, stable hip is a different problem from a labral tear in a dysplastic hip or one with advanced arthritis.

MRI or MR arthrogram

MRI can evaluate the labrum, cartilage, bone marrow, tendons, and other soft tissues. Some situations benefit from an MR arthrogram, in which contrast is placed in the joint before imaging, although modern high-quality MRI can identify many clinically important tears without an arthrogram.

The imaging choice depends on the question being asked, magnet quality, local protocols, and whether surgery is being considered.

CT scan

CT is not needed for every painful hip. It may be helpful when detailed three-dimensional bone anatomy, version, prior deformity, or surgical planning needs clarification.

Diagnostic injection

An image-guided injection of local anesthetic into the hip joint can sometimes help determine whether pain is coming from inside the joint. Meaningful temporary improvement during activities that usually hurt supports an intra-articular pain source.

An injection does not prove that a specific labral tear is responsible, and it does not establish that surgery will succeed. It is one piece of the diagnostic puzzle.

Can physical therapy help a hip labral tear or FAI?

Yes. Physical therapy does not reshape bone or stitch the labrum, but many patients can improve by changing how the hip is loaded and increasing the capacity of the muscles around the pelvis and trunk.

A good program is not simply a sheet of generic stretches. It may include:

Education about temporarily modifying provocative depth and positions
Progressive strengthening of the hip abductors, extensors, and rotators
Trunk and pelvic control
Improvement of single-leg mechanics
Gradual exposure to squatting, running, lifting, or sport-specific tasks
Cardiovascular training that does not repeatedly trigger a major flare
A planned progression back to the patient’s desired activity

Aggressive stretching into repeated painful impingement positions may make symptoms worse. The goal is also not to avoid hip flexion forever. A therapist can help find a tolerable starting point and rebuild motion and loading gradually.

The length of a trial depends on symptom severity, activity demands, and prior treatment. Many patients need at least 8 to 12 weeks of consistent, progressive work before judging the response. More complex return-to-sport goals may require longer.

Pacific Bone & Joint’s sports medicine program combines orthopedic evaluation, physical therapy, diagnostic imaging, and return-to-activity planning when appropriate.

What other nonsurgical treatments may help?

Activity modification

Short-term changes can reduce repeated irritation while strength improves. Examples include adjusting squat depth, changing a cycling position, avoiding repeated end-range pivoting, or reducing running volume temporarily.

Activity modification should be specific and time-limited when possible. Complete rest can reduce fitness and does not address strength or movement control.

Medication

Acetaminophen or a short course of a nonsteroidal anti-inflammatory drug may help selected patients. NSAIDs are not appropriate for everyone, particularly some people with kidney disease, gastrointestinal bleeding risk, cardiovascular disease, medication interactions, or pregnancy.

Medication may reduce a flare, but it does not correct bone shape or repair the labrum.

Injection

An ultrasound- or fluoroscopy-guided intra-articular corticosteroid injection may provide temporary relief and can sometimes help a patient participate in rehabilitation. Local anesthetic may also provide diagnostic information.

Steroid does not heal a labral tear. Repeated injections should not replace a clear diagnosis and a progressive treatment plan. Evidence for PRP and other biologic injections in labral tears and FAI remains insufficient to promise healing or avoidance of surgery.

When does hip arthroscopy make sense?

Hip arthroscopy may be considered when all or most of the following are present:

Symptoms are meaningfully limiting activity, work, sleep, or quality of life
The history and examination point to pain from inside the hip
Imaging shows a correctable labral and/or impingement problem that matches the symptoms
Joint space is reasonably preserved and advanced arthritis is absent
A structured nonsurgical program has not provided enough improvement
The patient understands the rehabilitation commitment, risks, alternatives, and uncertainty
The surgical plan addresses the underlying mechanics rather than treating an MRI tear in isolation

Age alone is not the deciding factor. Cartilage condition, arthritis, dysplasia, stability, symptom duration, activity goals, and overall health may matter more.

What happens during arthroscopy?

Through small incisions, a camera and instruments are introduced into the hip joint. Depending on the findings and plan, the surgeon may:

Repair the labrum when tissue quality and tear pattern allow
Remove a small area of irreparable labral tissue in selected cases
Reconstruct a deficient labrum in uncommon situations
Reshape a cam prominence
Trim selected acetabular overcoverage
Treat unstable cartilage
Close or tighten the capsule when appropriate

Not every operation includes every step. Removing bone without understanding dysplasia or instability can create problems, and treating only the labrum without addressing clinically important impingement may leave the cause of repeated contact in place.

What does the evidence say about physical therapy versus surgery?

Randomized trials in carefully selected patients without established arthritis show that both structured rehabilitation and hip arthroscopy can improve symptoms.

In the FAIT multicenter randomized trial, arthroscopy produced greater average improvement than physiotherapy and activity modification at eight months in selected patients with clinically and radiographically confirmed FAI and without established osteoarthritis. The trial does not mean that every patient with a cam shape or labral tear needs surgery. Read the FAIT trial on PubMed.

The UK FASHIoN randomized trial also found improvement with both personalized hip therapy and arthroscopy, with greater average hip-related quality-of-life improvement after arthroscopy at 12 months. It also emphasized that access delays, treatment burden, cost, and longer-term outcomes matter. Read the UK FASHIoN report on PubMed.

A 2026 systematic review found improvements in patient-reported outcomes after arthroscopy and relatively low average rates of reported major complications, but rated the certainty of evidence very low because much of the literature was nonrandomized and heterogeneous. Read the 2026 review on PubMed.

The practical conclusion is not “surgery always wins” or “therapy always works.” Start with an accurate diagnosis and a high-quality rehabilitation plan. If important symptoms persist and the hip has a surgically correctable problem with limited arthritis, arthroscopy may offer additional benefit.

When arthroscopy may be the wrong operation

Hip arthroscopy is less likely to help when pain is mainly driven by:

Advanced hip osteoarthritis or major joint-space loss
Unrecognized hip dysplasia or instability
Lumbar spine disease or nerve pain
Isolated lateral gluteal tendon pain
An abdominal-wall, pelvic, or adductor problem
Widespread pain without a clear intra-articular source
An imaging finding that does not match the symptoms

Advanced arthritis may lead to a hip-replacement discussion rather than a labral repair. Significant dysplasia may require a different joint-preservation strategy, such as a periacetabular osteotomy, rather than rim trimming or isolated arthroscopy.

Risks and alternatives to hip arthroscopy

Risks vary with the procedure and patient. They may include:

Persistent or recurrent pain
Temporary or, rarely, lasting numbness from traction or nerve irritation
Infection
Blood clot
Stiffness
Heterotopic ossification, or bone forming in soft tissue
Continued instability
Incomplete correction or excessive bone removal
Failure of the labrum or cartilage to heal
Repeat arthroscopy
Progression of arthritis and later hip replacement

Alternatives include continued activity modification, a revised physical therapy program, medication when safe, a diagnostic or therapeutic injection, further evaluation for another pain source, or accepting some symptoms while monitoring the hip.

The decision should compare the burden of current symptoms with the expected benefit, recovery, and risk of each option.

What is recovery after hip arthroscopy like?

Recovery depends on whether the labrum was repaired, how much bone was reshaped, whether cartilage was treated, and the surgeon’s protocol.

A general pathway may include:

Crutches with protected weight bearing for a period after surgery
Early controlled motion
Progressive hip and trunk strengthening
Restoration of walking mechanics
Gradual reintroduction of squatting, running, cutting, and sport-specific work
Criteria-based testing before unrestricted sport

Some patients use crutches for a few weeks. Running and impact activity usually return later, and cutting or pivoting sports may take several months. A 2026 study of a three-month therapist-led rehabilitation program after arthroscopy illustrates that recovery requires repeated exercise and that quality-of-life improvement does not guarantee that every strength or performance measure normalizes quickly. Read the rehabilitation study on PubMed.

Timelines should be individualized. Returning because a certain number of weeks has passed is less useful than demonstrating adequate motion, strength, control, and tolerance of sport-specific loading.

Special planning for patients traveling between islands

Patients who travel for evaluation or surgery should plan for more than the procedure date. Useful questions include:

Can initial imaging be completed close to home?
Where will preoperative and postoperative physical therapy occur?
Who will address wound, medication, or mobility concerns between visits?
When is air travel reasonable after surgery?
Is blood-clot prevention needed for the procedure and planned flight?
Which follow-up visits require an in-person examination?

The surgeon should provide individualized flight and clot-prevention guidance. Do not assume that a short interisland flight is automatically safe immediately after surgery.

Questions to ask at an orthopedic visit

Consider asking:

What finding best explains my pain?
Do I have FAI syndrome, or only an imaging shape?
Is the labral tear likely symptomatic?
How much cartilage damage or arthritis is present?
Is there dysplasia or instability?
What should a diagnosis-specific physical therapy program include?
Would a diagnostic injection change the plan?
If surgery is considered, which parts of the problem would be treated?
What are realistic return-to-work and return-to-sport milestones?
What would make continued nonsurgical care the better choice?

The bottom line

Hip labral tears and FAI are clinical diagnoses, not MRI diagnoses. Many patients improve with education, activity modification, and progressive physical therapy. Arthroscopy may provide additional benefit for carefully selected patients with persistent symptoms, limited arthritis, and a correctable problem that matches the examination and imaging.

If deep groin pain continues to limit sitting, work, exercise, or sport despite a thoughtful rehabilitation program, request a hip-preservation and sports-medicine evaluation to clarify the pain source and compare nonsurgical and surgical options.
