Arthroscopic debridement and synovium resection for inflammatory hip arthritis / 中国医学科学杂志(英文版)

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the efficacy of arthroscopic surgery in inflammatory hip arthritis.</p><p><b>METHODS</b>A retrospective clinical study was conducted inspecting 40 hips in 36 patients of inflammatory arthritis. There were 17 cases of ankylosing spondylitis, 11 cases of rheumatoid arthritis, and 8 cases of psoriatic arthritis. The joints were irrigated and the inflamed tissues were debrided with anthroscopy. The patients were followed up with Harris hip score, Oxford hip score, Visual Analog Scale (VAS), and magnetic resonance imaging (MRI). Statistical analysis was performed using Student t test.</p><p><b>RESULTS</b>All of the 36 cases were followed up for 46-103 months, averaging 67.2±8.4 months. Harris and Oxford scores increased from 66.9±12.1 and 69.4±16.4 before operation to 78.4±19.3 and 80.2±18.8 after operation, respectively (P<0.05). VAS score decreased from pre-operative 8.5±2.5 to post-operative 7.2±2.5 (P<0.05). All the patients showed improved joint range of motion. MRI revealed alleviation of hip synovitis. The results were classified as excellent in 8 patients, good in 17 patients, fair in 8 patient, and poor in 3 according to Harris hip score. Twenty-seven patients were satisfied with the operative outcomes as they regained normal daily activities.</p><p><b>CONCLUSIONS</b>Arthroscopy-assisted joint debridement and synovium resection is an effective procedure for hip lesion in inflammatory arthritis. The inflammatory lesion might be thereby controlled and the symptoms be relieved.</p>
