Abstract

PURPOSE
To evaluate the effectiveness of the hip arthroscopy in degenerative osteoarthritis. MATERIALS AND METHODS: Thirty four patients who were treated by hip arthroscopy under the impression of osteoarthritis were reviewed. We arbitrarily classified the patients into 4 groups based on plain radiographic and arthroscopic findings. Group I: radiographic findings were normal, but arthroscopic evidence of degeneration (11 cases), Group II: symptomatic mild dysplastic osteoarthritis (6 cases), Group III: symptomatic early osteoarthritis (13 cases), Group IV: moderate osteoarthritis (4 cases). We removed torn labra, loose bodies and osteophytes and performed synovectomy during the arthroscopy. Mean follow-up was 32.1 months (12-62). RESULTS: The mean HHS improved from 55.2 points to 80.3 points at a postoperative 6 months and to 80.6 points after 1 year. The mean improvement was 25.4 points. The corresponding improvement in JOA pain scores was 0.9 to 2.2. The results of the subjective satisfaction were Good: 25 cases (75%), Stationary: 7 cases (20.6%), Poor: 2 cases (5.9%). In case of dysplastic and moderate arthritis, results were poor or stationary. CONCLUSION: Arthroscopic labrectomy and synovectomy proved effective in early osteoarthritis, and in moderate cases, reduced pain temporarily.
