The purpose of this study was to investigate the correlation between fibular head height and the incidence and severity of osteoarthritis associated with varus knee deformity. The fibular head height, joint line convergence angle (JLCA) and medial proximal tibial angle (MPTA) were measured in a three-dimensional model. Ordinal multivariate logistic regression was used to analyze the correlation between fibular head height and Kellgren-Lawrence (K-L) grade. Pearson correlation was used to analyze the correlation between fibular head height and K-L grade. A total of 232 patients (232 knees) were finally included in the study. There were significant differences in JLCA and hip-knee-ankle angle ( < 0.05), and both JLCA and hip-knee-ankle angle increased with severe aggravation of K-L grade. Both fibular head height and MPTA decreased as the K-L grade was severely aggravated. There was a significant negative correlation between K-L grade and fibular head height ( = -0.812, < 0.001). Furthermore, there was a significant negative correlation between fibular head height and hip-knee-ankle angle ( = -0.7905, < 0.001). In addition to body mass index, fibular head height is a risk factor for the pathogenesis of osteoarthritis associated with varus knee deformity; the smaller the fibular head height, the more severe the degree of varus deformity.
本研究的目的是探讨腓骨头高度与膝内翻畸形相关骨关节炎的发生率及严重程度之间的相关性。在三维模型中测量腓骨头高度、关节线汇聚角（JLCA）和胫骨近端内侧角（MPTA）。采用有序多变量逻辑回归分析腓骨头高度与Kellgren-Lawrence（K-L）分级之间的相关性。采用Pearson相关性分析腓骨头高度与K-L分级之间的相关性。本研究最终共纳入232例患者（232个膝关节）。JLCA和髋-膝-踝角存在显著差异（<0.05），且JLCA和髋-膝-踝角均随K-L分级的严重加重而增加。随着K-L分级严重加重，腓骨头高度和MPTA均降低。K-L分级与腓骨头高度之间存在显著负相关（=-0.812，<0.001）。此外，腓骨头高度与髋-膝-踝角之间存在显著负相关（=-0.7905，<0.001）。除体重指数外，腓骨头高度是膝内翻畸形相关骨关节炎发病机制的一个危险因素；腓骨头高度越小，内翻畸形程度越严重。
