Analysis on arthroscopic debridement and visco supplement for the treatment of degenerative osteoarthropathy of ankle / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate effects of arthroscopic debridement and visco supplement for the treatment of degenerative osteoarthropathy of ankle.</p><p><b>METHODS</b>From October 2008 to May 2012, 30 patients with degenerative osteoarthropathy of ankle were treated with arthroscopy after ineffective treatment with conservative methods. Two patients lost follow-up. Among the patients, 19 patients were male and 9 patients were female, ranging in age from 28 to 56 years old, with a mean of (40.0+ 5.9)years old. Patients who had inflammatory or postinfectious arthritis,rheumatoid,gout,tuberculosis were excluded. Other exclusion criteria included previous arthroscopic treatment for ankle osteoarthropathy, intraarticular corticosteroid injection within the previous 6 months, a major neurologic deficit, serious medical illness and pregnancy. Articular cartilage iijuries were classified according to Outerbridge by the same doctor. Follow procedures were involved in the surgery synovectomy,debridement or excision of fragments of articular cartilage or chondral flaps and osteophytes that prevented full extension. Microfracture of chondral defects was not performed. Ogilvie-Harris criteria was used to evaluate therapeutic effects.</p><p><b>RESULTS</b>According to Ogilvie-Harris criteria, 10 patients got an excellent results, 14 good, 3 poor and 1 bad. The mean VAS score of pain decreased from preoperative 7.5+/-1.3 to postoperative 2.4+/-2.3. The score of dorsiflexion range (ROM-D) had no obvious change after operation [preoperative(27.0+/-7.3)degree and postoperative(29.0+/-5.6)degree]. The mean Tegner score increased from preoperative 2.7+/-1.3 to postoperative 5.6+/-2.2.</p><p><b>CONCLUSION</b>Synovectomy, debridement or excision of chondral flaps and osteophytes under arthroscopy, as well as scheduled intraarticular sodium hyaluronate injection should be recommened to treat ankle degenerative osteoarthropathy.</p>
