Hip arthroscopy is an effective method for the diagnosis and treatment of hip joint pathologies. However, gaining access to the central and peripheral compartments is challenging. The present study aimed to assess the advantages of using an arthroscopic extra-capsular approach and partial capsulotomy for access and subsequent management of hip diseases. Patients subjected to hip arthroscopy by partial capsulotomy for exposure and treatment of hip diseases between February 2012 and February 2016 were retrospectively analyzed. A total of 32 patients, including 19 males and 13 females, aged 19-48 years (median age, 36 years), had undergone the procedure. Firstly, the distal anterior lateral and anterolateral arthroscopic approach with blunt dissection was performed. Subsequently, a T-shaped partial capsulotomy was established to achieve adequate exposure. The shaver, radiofrequency probe and tissue penetrating suture grasper were then inserted to perform procedures including debridement of the synovium, suturing of the glenoid labrum. During surgery, a probe hook was used to push the capsule section limbs or pull the sutures placed on the capsule section limbs to improve exposure. For patients with pre-operative anterior instability, ligamentous laxity or acetabular dysplasia capsules were sutured to finish capsule closure. The pre-operative and post-operative Visual Analogue Scale (VAS) score and modified Harris hip score (MHHS) were used to assess the effectiveness of the procedure. No obvious post-operative complications were encountered. The mean follow-up time was 22.4 months (range, 18-32 months) and 31 patients completed the follow-up, while 1 patient was lost to follow-up. Compared with the pre-operative score, the MHHS was significantly increased (66.2 /- 6.0 vs. 82.6 /- 5.2; P<0.05) and the VAS score was significantly decreased (6.5 /- 1.1 vs. 1.2 /- 0.7; P<0.05) at the end of the follow-up. In conclusion, arthroscopic partial capsulotomy provides access to the peripheral and central compartments of the hip and is a relatively simple technique that is easy to master for surgeons with limited experience in hip surgery.
