摘要
目的分析骨性关节炎膝内翻角度的组成及软组织平衡术在全膝关节置换术中的矫正作用。方法对100例145个骨性关节炎膝内翻关节行全膝关节置换术,术中准确截骨并结合软组织平衡术矫正内翻。然后测量手术前后负重位X线平片,对比截骨与软组织平衡的矫正效果。结果全部膝内翻患者术前平均内翻角度为9.2°±3.1°(5°～30°),其中软组织失衡性内翻占53.2%,胫骨骨性内翻占22.8%,胫骨平台关节面磨损及破坏占24.0%。术后测量表明,胫骨平台截骨角度平均为4.3°,占膝内翻矫正度数的27.9%;软组织平衡术矫正的平均度数为10.7°,占膝内翻矫正度数的72.1%。全部病例术前膝关节HSS评分为38分(5～57分),术后出院时评分为87分(75～90分)。结论骨性关节炎膝内翻角度的组成有两方面:(1)胫骨结构性内翻:包括胫骨近端骨性内翻和膝关节内侧关节面的磨损及胫骨平台的破坏所导致的内翻;(2)膝关节侧副韧带及软组织失衡导致的内翻。测量结果表明骨性关节炎膝内翻中软组织失衡性内翻占膝内翻角度的主要部分,对于骨性关节炎膝内翻的关节置换,除准确的截骨外,正确的韧带松解及软组织平衡是手术矫形的关键。
Objective To analyze contribution of varus knee with osteoarthritis and investigate the role of soft tissue balance in total knee replacement ( TKR) of that. Methods One hundred cases (145 varus knees) were operated with TKR. There were 18 males (25 knees) and 82 females (120 knees), with the average age of 64.6 years, from 45 to 80 years old. During the operation, accurate osteotomy and soft tissue balance was made to correct the varus knee joint. The contribution angles of varus knee was measured on weight bearing X ray images pre and postoperatively, in order to evaluate the results of the combination of the osteotomy and soft tissue balance. Results The gross varus angle was average 9.2° ± 3.1° , ranging from 5° to 30° preoperatively. In the total angle, the varus angle caused by soft tissue imbalance was 53.2% , the osseous varus angles caused by the tibia varus was 22.8% , the osseous varus angles caused by tibia plateau destruction was 24.0% . The measurement of the postoperative X ray films suggested that the average angle of the tibia plateau osteotomy was 4.3° , obtaining the correction of 27.9% of the total varus angle, and the angles corrected by soft tissue balance was 10.7° ,getting the correction of 72.1% of the total varus angle. According to HSS score system, the preoperative score was 38 points, ranging from 5 to 57, and postoperative scores was 87 points, ranging from 75 to 90. Conclusion The contribution of varus knee with osteoarthritis were include: 1) Bony structural varus angle composed of tibial varus and tibial plateau destruction; 2) Collateral ligaments and soft tissue imbalance around the knee. Articular surface destruction and soft tissue imbalance are the main contribution of varus knee. For TKR of varus knees like this, besides accurate osteotomy, correct soft tissue balance is the key of the operation. [
