PURPOSE
This study aimed to clarify lower limb alignment characteristics and the relationship between coronal and sagittal lower limb alignment in Japanese patients with knee complaints but without knee osteoarthritis (KOA).
METHODS
This retrospective study included 200 knees from Japanese patients with knee complaints but without KOA aged 60 years and under presenting with knee complaints between May 2020 and May 2023. We assessed coronal parameters, including mechanical hip knee angle (mHKA), arithmetic HKA (aHKA) mechanical lateral distal femoral angle and medial proximal tibial angle (MPTA), and sagittal parameters, such as medial posterior tibial slope (MPTS) and lateral posterior tibial slope (LPTS). In addition, we compared differences between CPAK types.
RESULTS
A weak positive correlation was found between mHKA and MPTS, but not with aHKA. Moderate negative and moderate positive correlations were found between mHKA and MPTA and between medial and LPTS, respectively.
CONCLUSIONS
Little correlation was found between the coronal and sagittal parameters in patients with knee complaints but without KOA.
LEVEL OF EVIDENCE
Level Ⅲ.
目的
本研究旨在阐明日本膝关节有症状但无膝关节骨关节炎（KOA）患者的下肢对线特征以及下肢冠状面和矢状面之间的关系。
方法
这项回顾性研究纳入了2020年5月至2023年5月期间年龄在60岁及以下、膝关节有症状但无KOA的日本患者的200个膝关节。我们评估了冠状面参数，包括机械性髋膝角（mHKA）、算术髋膝角（aHKA）、机械性股骨远端外侧角和胫骨近端内侧角（MPTA），以及矢状面参数，如胫骨后内侧斜率（MPTS）和胫骨后外侧斜率（LPTS）。此外，我们比较了CPAK类型之间的差异。
结果
发现mHKA与MPTS之间存在弱正相关，但与aHKA无关。mHKA与MPTA之间以及内侧与LPTS之间分别存在中度负相关和中度正相关。
结论
膝关节有症状但无KOA的患者，其冠状面和矢状面参数之间相关性较小。
证据水平
Ⅲ级。
