目的本研究旨在分析高位胫骨截骨后冠状胫股半脱位的变化，并确定与冠状胫股半脱位相关的人口统计学变量。假设CTF半脱位的变化与下肢对齐和内侧胫骨近端角（MPTA）的矫正程度有关。方法回顾性分析86例行内侧开口楔形胫骨高位截骨术治疗症状性内侧间室膝骨关节炎的103个连续膝关节。正常的%CTF半脱位值，定义为胫骨近端相对于股骨远端在股胫关节外侧边缘的半脱位，由60个正常膝关节确定。检查CTF半脱位与膝关节社会评分（KSS）和影像学参数之间的关系。结果CTF半脱位的正常范围为- 1.8 ~ 5.6%。截骨后，CTF半脱位百分比从平均4.5%（- 12.1%至- 4.6%）降至0.7%(- 6.8至8.2%)，导致外侧胫股半脱位减少，同时内侧半脱位增加。CTF半脱位的减少与MPTA变化中度相关(r = - 0.454, p
PurposeThis study aimed to analyse the change in coronal tibiofemoral (CTF) subluxation after high tibial osteotomy and to determine demographic variables associated with CTF subluxation. The change in CTF subluxation was hypothesised to be associated with the magnitude of correction of lower limb alignment and medial proximal tibial angle (MPTA).MethodsA total of 103 consecutive knees in 86 patients who underwent medial opening wedge high tibial osteotomy for symptomatic medial compartment knee osteoarthritis were retrospectively analysed. The normal %CTF subluxation value, which was defined as a subluxation of the proximal tibia relative to the distal femur on the lateral edge of the femorotibial joint, was determined from 60 normal knees. The association between CTF subluxation and the Knee Society Score (KSS) and radiographic parameters was examined.ResultsThe normal range for %CTF subluxation was defined as - 1.8 to 5.6%. Following osteotomy, %CTF subluxation reduced from a mean of 4.5% (- 12.1 to - 4.6%) to 0.7% (- 6.8 to 8.2%), resulting in a decrease in lateral tibiofemoral subluxations concomitant with an increase in medial subluxations. The reduction in CTF subluxation correlated moderately with MPTA change (r = - 0.454, p
