关节镜下膝关节灌洗清理术治疗膝骨关节炎疗效分析

【目的】观察关节镜下膝关节灌洗清理术治疗膝关节骨关节炎（0A）的疗效。【方法】对本院收治的52例OA患者行关节镜检查及镜下关节腔冲洗清理术52例。应用VAS视觉模拟标尺法、日本骨科协会（JOA）的膝关节骨性关节炎评分系统分别于治疗前及治疗后1个月和2年进行疗效评估。【结果】与治疗前相比，治疗后1个月和2年，VAs明显下降，JOA评分明显上升，且差异有显著性（P〈0．05）。远期疗效：与治疗前比，治疗后1个月JOA评分改善率明显增加，但随着时间推移逐渐下降。【结论】关节镜下膝关节灌洗清理术治疗0A具有良好的近期疗效，但远期疗效稍差。

Analysis on Long-and Short-term Efficacy of Arthroscopic Lavage Debridement for the Treat-ment of Knee Osteoarthritis

Objective] To observe the efficacy of arthroseopic lavage debridement for the treatment of knee osteoarthriti （OA）. Methods] Totally 52 OA patients admitted to our hospital underwent arthroscopy and endoscopic joint cavity rinse. Visual analogue scale（VAS） and knee osteoarthritis scoring system of Japa- nese orthopaedic assoeiation（JOA） were used to evaluate the efficacy before treatment and 1 month and 2 years after treatment, respectively. Results] Compared with before treatment, VAS score at 1 month and 2 years after treatment obviously decreased and JOA score obviously increased, and there was significant difference（ P 〈0.05）. Compared with before treatment, the improvement of JOA score 1 month after treatment obviously increased, but obviously decreased 2 years after treatment in comparison with 1 month after treatment. Conclusion]Arthroscopic knee joint lavage debridement for the treatment of knee OA has a good short-term effect, but its long-term effect is slightly poor.
