Soft-tissue balancing during total knee arthroplasty is an important step in optimizing the mechanical balance of the knee joint. Soft-tissue contractures that result from varus coronal plane deformity can pose a difficult problem, and the surgeon should have a standard procedure for managing such situations in the operating room. Balance may be assessed intraoperatively with the use of spacer blocks, laminar spreaders, and tensioning devices as well as by placement of trial components. Techniques used to balance the varus knee during primary total knee arthroplasty include femoral component rotation, osteophyte resection, soft-tissue release, and bone resection. Flexion and extension gap balancing is crucial for long-term success and patient satisfaction.
在全膝关节置换术中进行软组织平衡是优化膝关节机械平衡的重要步骤。由冠状面内翻畸形引起的软组织挛缩会带来难题，术者应该在手术室中采用标准方法来处理此类情况。术中可使用间隔块、层板撑开器和张紧装置以及试模组件来评估平衡。用于初次全膝关节置换术中矫正内翻膝的技术包括股骨组件旋转、骨赘切除、软组织松解和骨切除。屈伸间隙平衡对于长期成功和患者满意度至关重要。
