关节镜微创清理术治疗膝关节骨性关节炎

目的探讨关节镜下微创清理术对膝关节骨性关节炎（OA）的治疗效果。方法对54例膝关节骨性关节炎患者进行关节镜下选择性、有限化微创清理术。手术内容包括刨削或射频汽化增生的炎性滑膜组织和前交叉韧带（Anterior Cross Ligment）磨损、游离体取出、软骨打磨成形、增生髁间棘切除、部分骨赘切除、半月板部分切除、髁间窝成形。结果随诊45例。平均18个月（6-24月），大多数患者临床症状明显缓解，关节功能改善。结论关节镜微创清理术可有效缓解OA症状，改善关节功能，提高生活质量。

Minimally Invasive Debridement under Arthroscope for Patients with Osteoarthritis of Knee Joint

Objective To discuss the curative effect of minimally invasive debridement under arthroscope for patients with osteoarthritis(OA) of knee joint. Methods Selective and limited minimally invasive debridement under arthroscope was applied to 54 patients with osteoarthritis of knee joint;hyperplasia of inflammatory synovial membrane and abrasion of anterior cruciate ligament were chipped or vaporized with radiofrequency,the corpus liberum were taken out,cartilage was scoured into certain shape;excision or partial excision were performed to hyperplastic intercondyloid spine,osteophyma and menisci;intercondyloid fossa was formed.Results 45 cases were followed up for an average of 18 months(from 6 months to 24 months);the clinical symptoms of most cases released obviously and the joint function improved.Conclusions Minimally invasive debridement under arthroscope can effectively release OA symptoms,improve joint function and raise the quality of life.
