摘要

目的本研究旨在阐明日本无膝骨关节炎（KOA）患者的下肢直线特征以及冠状面和矢状面下肢直线之间的关系。方法本回顾性研究纳入了2020年5月至2023年5月期间，年龄在60岁及以下，有膝关节主诉但无KOA的日本患者200个膝关节。我们评估了冠状面参数，包括机械髋关节膝关节角（mHKA）、算术HKA （aHKA）、机械股骨远端外侧角和胫骨近端内侧角（MPTA），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mHKA与MPTS呈弱正相关，与aHKA无显著正相关。mHKA与MPTA、medial与LPTS分别呈中度负相关和中度正相关。结论无KOA患者的冠状面和矢状面参数相关性不大。证据级别Ⅲ。

Comparison of coronal and sagittal alignment in patients without osteoarthritis but with knee complaints

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.
