Overview
The acetabular labrum is a ring of fibrocartilage on the rim of the hip socket. It deepens the socket and forms a seal that keeps joint fluid pressurized so the ball floats on a film rather than grinding on bone. A tear is a split in that ring or a separation from the rim, most often at the front and top of the socket where deep flexion loads it.
Labral tears rarely happen on their own. In most patients under 50 the underlying cause is femoroacetabular impingement, a bony bump or over-covering rim that has been levering against the labrum for years; in a smaller group it is a shallow socket. What decides treatment is the cause, the state of the cartilage, and whether the hip settles with rehabilitation.
Common Symptoms
- Deep groin pain, often shown with a cupped hand over the side of the hip, worse with deep flexion, pivoting and prolonged sitting
- Clicking, catching or a sense of something moving in the joint when rising from a chair or turning in bed
- Locking or giving way with a twist — a displaced fragment of labrum catching in the joint
- Pain with rotation on a planted leg: golf, tennis, hockey, soccer, dance
Mechanical catching separates a labral tear from most other hip pain. Outer-hip pain that is tender to press on is greater trochanteric bursitis; groin pain with morning stiffness and a narrowed joint on X-ray is hip arthritis; buttock pain after a sprint is a hamstring injury.
Causes & Risk Factors
Impingement is the usual cause: a cam bump or a pincer rim grinds the labrum with every deep bend, and the tear appears in the 20s or 30s after years of hockey, soccer, football, rowing or ballet. Dysplasia, a socket too shallow to cover the ball, is the next cause and is more common in women. A dislocation, a fall onto the side or a violent twist can tear a normal labrum. After 40 the labrum frays with ordinary use, and those degenerate tears are managed alongside early arthritis rather than repaired.
How It Is Diagnosed
Dr. O'Donnell uses the FADIR test — flexion, adduction and internal rotation — which reproduces the groin pain by driving the ball against the front of the labrum, and the FABER test, which loads the back of the joint. Internal rotation in 90° of flexion is measured against the other side, and ligamentous laxity is scored, because a hypermobile patient with a dysplastic socket needs a different plan from a stiff cam hip.
X-rays come first: an AP pelvis and a Dunn lateral show whether there is a cam or pincer shape, whether the socket is shallow (a center-edge angle under about 20°), and how much joint space remains. MRI arthrogram, with contrast injected into the joint before scanning, is the most reliable way to see the labrum and the cartilage beside it. Imaging can be uploaded through mymedicalimages.com before a telemedicine consultation.
Treatment Options
Non-operative care
Most labral tears are treated without surgery first for 6 to 12 weeks. The positions that pinch — deep squats, low seats, long drives, deep hip stretches — are cut back, and physical therapy builds gluteal and core control so the hip is stabilized mid-range where the labrum is not loaded. An ultrasound-guided corticosteroid injection into the joint settles an irritable hip so therapy can progress. The tear does not heal, because the labrum has almost no blood supply, but many patients become and stay comfortable, and for a degenerate tear over 45 that is the goal.
Hip arthroscopy with labral repair
When groin pain and catching persist after a proper course of rehabilitation, the exam reproduces the pain, and X-rays show a preserved joint space with a correctable cam or pincer shape, Dr. O'Donnell performs hip arthroscopy. The torn labrum is reattached to the rim with suture anchors to restore the seal, and in the same operation the bump or rim that caused the tear is reshaped; leaving the bone alone is why repairs re-tear. Frayed tissue that will not hold a stitch is trimmed instead. The procedure is outpatient at Bayside Surgery Center. It is not recommended when the joint space is narrowed to about 2 mm or less, nor for a dysplastic socket, where the labrum will fail again unless the socket itself is addressed.
Recovery & What to Expect
After arthroscopic repair the sutured labrum and closed capsule are protected while motion returns, and each phase of Dr. O'Donnell's protocol is entered on criteria rather than dates.
| Phase | Timing | What happens |
|---|---|---|
| Protection & motion | Weeks 0–3 | Partial weight bearing on crutches at about 20 lb. No active flexion past 90°, no extension with the leg turned out. Passive motion and circumduction, high-seat bike without resistance, isometrics, heel slides. |
| Progressive motion & load | Weeks 3–6 | Crutches weaned as gait normalizes; full motion restored while pinching positions are avoided. Bridges, mini-squats, core and gluteal work, balance. No pivoting or aggressive stretching before 6 weeks. |
| Strengthening | Weeks 6–12 | Progressive resistive hip and core strengthening, single-leg work, elliptical. Jogging late in the phase once strength reaches 80% of the other side. |
| Return to sport | Months 3–6 | Running, then agility, cutting and plyometrics, then sport-specific drills. Cleared at typically 4 to 6 months on symmetric strength and hop testing. |
Plan on desk work within 1 to 2 weeks and driving once off crutches and narcotic pain medication at about 3 weeks; after a microfracture, crutches continue longer. Full details are in the hip arthroscopy protocol PDF.
Frequently Asked Questions
Can a hip labral tear heal on its own?
No. The labrum has almost no blood supply, so a torn one does not heal back together. What often happens is that the hip stops hurting: with 6 to 12 weeks of activity modification and mid-range stabilization work, many patients become comfortable even though the tear is still visible on MRI.
Do I need surgery for a hip labral tear?
Only if rehabilitation fails. Dr. O'Donnell recommends hip arthroscopy when groin pain and catching persist after a proper course of therapy, the exam reproduces the pain, and X-rays show a preserved joint space with a cam or pincer shape that can be corrected at the same time.
Will a labral tear cause arthritis?
It raises the risk, because the labrum's seal keeps the cartilage bathed in pressurized fluid, and the cartilage next to a tear carries extra load. The bigger driver is the impingement underneath: a cam bump keeps shearing cartilage whether or not the labrum is repaired, which is why the bone is reshaped during repair.
Can I walk after hip labral tear surgery?
Yes, with crutches. For 2 to 3 weeks you put roughly 20 pounds through the leg with the foot flat, to protect the repair and the capsule closure. Crutches are weaned between weeks 3 and 6 as your gait normalizes; after a microfracture the crutch period is longer.
Can I still work out with a labral tear?
Usually, with changes. Cycling with a high seat, swimming and mid-range strength training are generally tolerated. Deep squats, lunges past 90°, low-seat rowing, deep yoga hip openers and pivoting sports load the torn labrum and are cut back while the hip is irritable.
