Abstract:[Objective] To introduce the surgical technique and preliminary clinical results of arthroscopic repair of acetabular labrum tear from the peripheral to central compartments. [Methods] The patient was placed in supine position on the fracture table after general an- esthesia, with the affected low limb in the internal rotation, hip flexion of 10° and abduction of 25°. The body surface markers were made on the front and lateral sides of the hip with the assistance of "C" arm fluoroscopy. A blunt trocar was inserted through the anterolateral portal, and as a tough tissue was felt, the trocar was moved from one side to other side to separate the tissues around the capsule, then inner trocar was pulled out and the arthroscope replaced. As the hip anterior capsule was exposed under arthroscope, “Y” shaped capsulotomy was done with a plasma cutter introduced from the anterior portal to reveal the anterolateral aspect of the hip joint, and the peripheral compart- ment was examined. Pulling the affected limb, the central compartment was exposed. Finally, the acetabular labrum injuries were evaluated and repaired with suture anchors. [Results] All patients were operated on smoothly without serious complications during the operation, and were followed up from 24 to 96 months. Compared with those preoperatively, the VAS score for pain [(6.7±1.2), (2.1±0.7), P＜0.001] and Harris score [(52.8±6.4), (86.9±4.7), P＜0.001] significantly improved at the latest follow-up. During the follow-up period, no revision or secondary surgery was performed in anyone of the patients. [Conclusion] This arthroscopic repair of acetabular labrum tear from the periph- eral to central compartments is feasible technique with shortened traction time, does achieve satisfactory preliminary clinical consequences.
