A hip labral tear is an injury to the labrum, the fibrous ring of cartilage that surrounds the rim of the hip joint socket (acetabulum). The labrum acts as a cushion and helps stabilize the hip joint by keeping the head of the femur (thigh bone) properly aligned in the socket.

(A) The acetabular labrum is the cartilage gasket at the rim of the socket.

(C) During arthroscopic surgery, the labrum is a seen as continuation of the articular (joint) cartilage at the rim of the socket
Hip arthroscopy is a minimally invasive surgical procedure used to address painful hip pathology that results from hip instability or femoroacetabular impingement (FAI). Damage to the acetabular labrum and articular cartilage from hip microinstability or FAI often results in painful pathology including arthritis. The labrum plays a key role in establishing a suction seal, which helps stabilize the joint, preserve joint function, and delay the need for a hip replacement.
Depending on the extent of degeneration and tearing, the damaged segment of the labrum can be debrided (removed), repaired or reconstructed from cadaver tissue (Figure 1).

Debridement and removal of a damaged labrum along with removal of bone spurs from the rim of the acetabulum using a bur in a procedure (acetabuloplasty).

After acetabuloplasty, a damaged labrum can often be repaired or re-fixated to the acetabular rim using suture anchors.

An irreparable labrum has been debrided and removed (as in 1A) and reconstructed with fascia lata allograft fashioned into a cylindrical graft.
A hip labral repair is a surgical procedure to treat damage to the labrum, a ring of cartilage that surrounds the hip joint socket (acetabulum). The labrum plays a critical role in stabilizing the joint, cushioning the hip, and maintaining smooth motion. Damage to the labrum, often referred to as a labral tear, can result from trauma, overuse, or structural issues like instability or femoroacetabular impingement (FAI).
Arthroscopy to repair a labrum tear is typically performed when:
The Procedure

Labral tear

Torn labrum elevated off acetabular rim

Removal of bone from acetabular rim

Completion of acetabuloplasty

All-suture anchors (no screws)

Labral repair with 3 all-suture anchors

Suction seal is restored when traction is released

Flexing hip to confirm reshaped femoral neck does not impact repaired labrum
Post-Operative Recovery
Risks
Like any surgery, hip labral repair carries risks, including:
Restoring the Suction Seal
By reattaching the labrum to its proper position, labral repair surgery can restore the suction seal, which improves joint stability and decreases the stress on the joint cartilage. Restoring the suction seal is an important goal of hip arthroscopy, as it is essential for joint health, mobility, and long-term function
Mechanical issues and joint deformity, such as instability and femoroacetabular impingement, must be addressed appropriately. Otherwise, the successful outcome of labral repair surgery may be compromised, and the patient may remain symptomatic. Addressing instability and FAI may also prevent further cartilage damage and the progression of arthritis.
