关节镜清理术治疗膝关节骨关节炎

目的：探讨关节镜下清理术对膝关节炎的诊断价值及治疗效果。方法：作者自1995年5月至1999年5月采用关节镜下清理术治疗膝关节骨关节炎患者56例（70膝），随访6月－4年。结果：本组病人56例（70膝），经关节镜检查均证实有关骨节炎存在，而术前X线片有关破坏的仅36膝，符合率为51．4％。本组病人术后疼痛明显减轻，2－3周即下床活动，随访1年优良率91％，2年以后优良率67．8％。结论：关节镜下清理术膝关节骨关节炎可以有效缓解病人的疼痛，可以早期恢复关节的功能，延迟骨关节炎的病程，全面提高诊断的准确率。

Arthroscopic Debridement for the Treatment of Osteoarthritis of the Knee

Objective: To investigate the diagnostic superiorty and remedial results of arthroscopic debridement for osteoarthritis of the knee.Methods 56 cases(70 knees)of osteoarthritis of the knee were treated with arthroscopic debridement from May 1995 to May 1999.The follow-up duration was from six months to four years.Results Osteoarthritis of the knees were confirmed in all the cases (70 knees) in arthroscopy,while only in 36 knees articular damages in X-ray film were investigated with the coincidence rate of 51.4%.The pain of knee after operation was decreased and exercises were encouraged in 2 to 3 weeks.The rate of the fine in follow-up of one year was 91%;in follow-up of two years was 67.8%.Conclusion Arthroscopic debridement may efficiently remit patient's pain,restore the articular function,delay the course of osteoarthritis of the knee and increase the accuracy of diagnosis.
