Abstract

Background: Closed-wedge high tibial osteotomy (CWHTO) with a fibular osteotomy (FO) causes medial joint space widening in the knee. However, the effect of FO on the joint space width remains unclear.

Objective: This study aimed to examine the effect of FO on the knee in HTO.

Methods: A compression load test was performed on two amputated human limbs under four conditions: (1) normal (without any osteotomy), (2) open-wedge HTO (OWHTO), (3) OWHTO with FO, and (4) CWHTO. The contact area of the femoral and tibial cartilages and the medial and lateral joint space widths in each condition were evaluated using a motion capture system with computed tomography (CT) and magnetic resonance imaging (MRI) data.

Results: The contact area increased on the lateral side after OWHTO, which increased more on the lateral side with a concomitant decrease on the medial side in both subjects when FO was added to OWHTO. An increase in the medial joint space width and a decrease on the lateral side were seen in both OWHTO with FO and CWHTO.

Conclusions: The contact area and joint space widths are affected by the FO, and the effect is more pronounced than the way of HTO (OWHTO or CWHTO).

胫骨高位截骨中腓骨截骨对膝关节的生物力学影响:一项尸体研究。

背景:闭合楔形高位胫骨截骨术(CWHTO)联合腓骨截骨术(FO)导致膝关节内侧关节间隙变宽。然而，FO对关节间隙宽度的影响尚不清楚。目的:本研究旨在探讨大关节损伤对膝关节的影响。方法:在4种情况下对2条人体截肢肢进行压缩负荷试验:(1)正常(未截骨)，(2)开楔HTO (OWHTO)， (3) OWHTO伴FO， (4) CWHTO。采用运动捕捉系统，结合计算机断层扫描(CT)和磁共振成像(MRI)数据，评估每种情况下股骨和胫骨软骨的接触面积以及内侧和外侧关节间隙宽度。结果:在OWHTO中加入FO后，两组受试者的外侧接触面积增加，外侧接触面积增加较多，内侧接触面积减少。在有FO和CWHTO的OWHTO中，内侧关节间隙宽度增加，外侧关节间隙宽度减少。结论:FO对关节接触面积和关节间隙宽度的影响明显大于HTO (OWHTO或CWHTO)方式。
