To present arthroscopic findings after traumatic posterior hip dislocation in patients with mechanical hip symptoms.
All the patients that were treated with hip arthroscopy for mechanical hip symptoms after traumatic posterior hip dislocation with subsequent closed reduction between 2002 and 2006 were included in this study. The time between closed reduction and arthroscopy, arthroscopic findings and treatment, preoperative and last follow-up WOMAC scores and last follow-up X-rays were analyzed. Complications or the need for further surgical treatment are reported.
We had 17 patients (13 male, 4 female), average age 28.5 years (range 19-37). Average time between closed reduction and arthroscopy was 3 months. 14 had anterior labral tears, 6 had posterior labral tears, 16 had acetabular chondral damage, all had femoral chondral damage, 14 had intra-articular fragments. Preoperative WOMAC was 46, last follow-up WOMAC was 87 (45 months average), range 45 to 93. One patient required Total Hip Replacement for Osteoarthritis and one presented avascular necrosis and is waiting for hip replacement.
Our clearest indication for arthroscopy after traumatic posterior hip dislocation was loose fragments inside the joint. Every patient presented mechanical hip symptoms, intra-articular damage was demonstrated in every case. Most of the patients had significant improvement after hip arthroscopy.
