算数髋膝踝角与膝关节单髁置换术患者下肢固有力线的关系研究
The study on the relationship between the arithmetic hip-knee-ankle angle and constitutional alignment of the lower limb in patients undergoing unicompartmental knee arthroplasty
摘要
Abstract
Objective To describe and validate the applicability of arithmetic hip-knee-ankle angle(aHKA)for predicting the constitutional alignment(pre-arthritic alignment)of the lower limb in Chinese patients with knee osteoarthritis(KOA)who underwent medial unicompartmental knee arthroplasty(UKA).Methods This study enrolled 69 patients who underwent medial UKA(normal knee on the non-surgical side)at the China-Japan Friendship Hospital from May 2019 to May 2022.Radiographic parameters,including the mechanical distal lateral femoral angle(LDFA),the mechanical medial proximal tibial angle(MPTA),and the hip-knee-ankle angle(HKA),were measured on weight-bearing full-length radiographs,and aHKA was defined as 180°-LDFA+MPTA.Outcomes included comparison of the aHKA of lower limbs affected by KOA with the HKA of lower limbs with normal knee joints,as well as assessing the correlation and consistency between the two.Results There was no statistically significant difference between the aHKA(177.90°±1.96°)of the lower limbs with KOA and the HKA(178.08°±1.98°)of normal knee joints(P=0.357)in patients who underwent UKA,but there was a strong correlation(r=0.741,P<0.001)and good agreement(97.1%of the data in the Altmann plot were at the 95%limit of agreement,95%LOA)between the two.Conclusion This study provides preliminary evidence that aHKA may reflect the constitutional alignment of the lower limb in Chinese patients with KOA who underwent UKA.This parameter can be used for preoperative planning of the lower limb alignment in UKA.关键词
