关节平衡术治疗膝关节骨性关节炎的临床研究

目的探讨关节平衡术治疗膝关节骨性关节炎的方法和临床价值。方法回顾性分析自2006年1月～2007年12月以来采用关节平衡术（关节镜下清除术、关节内注射玻璃酸钠、膝关节矫形术）治疗膝关节骨性关节炎72例的临床资料。结果本组临床疗效优、良者60例（83．3％），一般8例，较差者4例。结论关节平衡术选择性应用，能显著改善膝关节骨性关节炎关节功能，缓解病痛，提高疗效和改善患者的生活质量。

Lateral epicondylar osteotomy for severe varus deformity during total knee arthroplasty

In most cases of arthritic varus knees, stepwise osteophytes removal and medial soft tissue release could achieve satisfactory soft tissue balance during total knee arthroplasty. However, in some severe cases, conventional balancing techniques are not enough, necessitating other procedures like epicondylar osteotomy. To the best of our knowledge, no published article has reported the application of lateral epicondylar osteotomy in a severe varus knee. Here we reported a case of successful correction of a severe varus knee following lateral epicondylar osteotomy, and described its underlying rationale.
