    Author: Rühmann O, Wünsch M, Lipka W, Stark DA, Lerch S.
    Journal: Oper Orthop Traumatol; 2014 Aug; 26(4):341-52. PubMed ID: 25091159.
    Abstract:
    OBJECTIVE: Increase of range of motion and pain reduction for pain limited movement of the hip joint by arthroscopic arthrolysis of the peripheral compartment. INDICATIONS: Painful primary or secondary restriction of movement of the hip joint with adhesive capsulitis and after previous surgery or additional arthroscopically treatable intra-articular changes. CONTRAINDICATIONS: Extensive periarticular ossification, severe arthrofibrosis and advanced arthritis of the hip. SURGICAL TECHNIQUE: Arthroscopy of the peripheral compartment of the hip, initially using a lateral portal for the arthroscope and an anterolateral portal for instruments. After expansion of the portal entry site with a shaver and/or HF applicator and removal of scar tissue between the capsule and femoral neck, the capsule is reduced from anterolateral to anteromedial. After exchange of arthroscope and working portal, the lateral and dorsolateral arthrolysis is done. POSTOPERATIVE MANAGEMENT: Administration of nonsteroidal anti-inflammatory drugs for prophylaxis of heterotopic ossifications. Thrombosis prophylaxis with heparin. Mobilization with full weight bearing. Intensive physiotherapeutic exercises for at least for 6 weeks and if needed for 12 postoperative weeks. RESULTS: After arthroscopic (n=38) or open (n=11) hip surgeries, 49 revision hip arthroscopies were performed from January 2009 to August 2013. Arthrolysis in the described technique was performed if adhesions were present. In 19 of these cases, a limitation of at least 30 % for one direction of movement was present pre-operatively. The following average values were obtained for the range of motion (preoperative/postoperative/increase): flexion 94°/128°/34 °, abduction 18°/40°/22°, internal rotation of 8°/20°/12°, external rotation 18°/38°/20°.
