骨性关节炎行全膝关节置换术中软组织平衡的探讨(2)
所以从我们的手术经验来看,良好软组织平衡的全膝关节置换术,应达到以下目标:①矫正内外翻畸形,获得精确的假体对线;②伸膝、屈膝间隙的对称化,成矩形;③术后髌股轨迹正常;④膝关节稳定性和活动度要协调。对于关节稳定性和活动度之间的协调也是影响术后功能的一个重要方面,原则上宁松勿紧。在早期的患者中发现,较紧的关节术后康复训练更为困难。但关节亦不能过松,一般以被动内外翻时,关节间隙张开不超过5 mm为度。总之,在全膝关节置换术中衡量内外及屈伸间隙软组织平衡时,要根据术前影像学及术中所见分析造成畸形的原因,针对性地在纠正屈曲畸形同时进行软组织松解,纠正内外翻畸形,并且要保持内外侧副韧带稳定性。
