Femoroacetabular impingement (FAI) is the underlying structural issue behind many young-adult hip pains - anterior groin pain, pain with deep squatting, pain with prolonged sitting, stiffness after sport.
The condition describes bony abnormalities at the hip joint that cause the femoral neck and acetabular rim to contact each other in deep flexion, pinching (impinging) the labrum and cartilage.
Three subtypes:
- Cam impingement - extra bone on the femoral neck. Common in young male athletes (football, martial arts).
- Pincer impingement - over-coverage from the acetabular rim. More common in middle-aged women.
- Mixed - both present together. Around half of symptomatic FAI cases.
Diagnosis is by hip-specific X-rays (alpha angle, lateral centre-edge angle measurements) and often MRI to assess labrum and cartilage.
Significant structural findings don't always equal symptomatic disease - many asymptomatic athletes have cam morphology on imaging.
The conservative-first argument
Randomised trials now show comparable outcomes at 2 years between hip arthroscopy and structured physiotherapy for symptomatic FAI in carefully-selected patients.
The implication: surgery isn't automatically the answer.
Conservative care succeeds in:
- Patients with less extreme structural deformity.
- Patients whose demands don't require deep flexion or aggressive cutting (not competitive football, martial arts, or hurdlers).
- Patients who engage with the programme consistently.
The 16-week programme
Weeks 1–4: decompress the joint, basic strength
- Avoid the specific impingement positions (deep hip flexion with internal rotation).
- Hip flexor, adductor, and rectus femoris soft tissue work - often excessively tight in FAI.
- Isometric glute medius and glute maximus loading.
- Core stabilisation basics - transversus abdominis, multifidus, oblique activation.
Weeks 5–10: progressive strength
- Progressive glute medius loading - side-lying, standing, single-leg.
- Progressive glute maximus loading - hip thrusts, step-ups, hinge patterns.
- Hip external rotator strengthening - the deep external rotators are often weak.
- Functional squat patterns with depth control - deep squatting is often modified to parallel or slightly above, respecting the bony constraint.
Weeks 11–16: loaded sport-specific
- Cutting and pivoting drills.
- Progressive return to running or sport-specific demands.
- Movement pattern retraining - many FAI patients hinge from the low back rather than the hip; correcting this reduces compensation loading.
Activity modifications worth keeping
Some positions will always load the FAI hip more than others. For life-long management:
- Deep squats with knees collapsing inward - avoid or modify.
- Cross-legged prolonged sitting - often aggravating; a cushion that raises the hip above knee level helps.
- Low sofas and deep armchairs - same principle.
- Martial arts with deep kicks - may need technique adjustment.
- Cycling - saddle height and reach can be adjusted to reduce extreme hip flexion.
Decision point at week 16
- Meaningful improvement, back to most activities: continue maintenance strength (twice weekly indefinitely), surgery not needed.
- Partial improvement, still limited in specific activities: consider another 8–12 weeks, or assess whether the limitation matches realistic life goals.
- No improvement or worsening: return to the hip surgeon for arthroscopy discussion.
Around 55–65% of Johor patients on our structured programme sit firmly in the first category at 16 weeks.
When arthroscopy is the right answer
- Young elite athletes with very clear cam deformity and clear labral pathology.
- Patients whose sport or work demands require repetitive deep flexion (rugby, hockey, football, rower, dancer).
- Patients who engaged with conservative care for 16–24 weeks without meaningful improvement.
Arthroscopic osteochondroplasty (reshaping the cam or pincer), combined with labral repair or trimming, has good outcomes in selected cases.
Post-surgical rehab is 4–6 months.
Typical Johor costs
- Conservative course: 16–20 sessions at RM120-250.
- Hip arthroscopy (private): RM 18,000–35,000.
- Pricing: Physio pricing is shown as RM120-250 per session; total spend depends on the number of sessions needed.
How PhysioJohor matches FAI patients
WhatsApp us with: imaging findings (alpha angle, labral status if known), which activities hurt, and what you want to return to.
We match to a physio with hip preservation experience - FAI rehab is not generic hip strengthening and the progression rules depend on the specific deformity.
