背景：内侧半月板挤压（MME）由于机械应力增加而导致症状性膝关节骨关节炎（OA）。MME随负重增加而增加，非负重状态与负重状态之间的MME差异（Delta MME）是导致MME增大的一个因素，外侧楔形鞋垫（LWI）是降低Delta MME量的理想方法，与膝关节OA早期内侧负荷应力的降低相关。目的：探讨低强度运动干预3个月对OA各期MME和Delta MME的影响对照组（n = 9）和早期OA（早期OA组：Kelling-Lawrence（K/L）分期= 2，n = 17）和晚期OA（晚期OA组：K/L分期> 2，n = 13）的LWI干预。使用超声评估MME，并且获得Δ MME作为MME与非承重和承重条件的差异。这些测量在两个时间点进行：作为基线的初始办公室访问和3个月后。结果：3个月后的负重MME和Delta MME值在早期OA组中与基线相比显著降低，但在对照组或晚期OA组中没有降低。使用LWI 3个月可降低负重MME和Delta MME值，其有效性在膝关节OA早期更为明显。(C)2020爱思唯尔B.

Background: Medial meniscus extrusion (MME) leads to symptomatic knee osteoarthritis (OA) due to increased mechanical stress. MME increases with weight-bearing, and the difference in MME between non-weight-bearing and weight-bearing status (Delta MME) is a factor that causes greater MME. The lateral wedge insole (LWI) is an ideal approach for decreasing the amount of Delta MME associated with the reduction of medial loading stress in the early stage of knee OA. However, the effect of the LWI for 3 months on the DMME and its response to OA stage have not been elucidated.Objective: To investigate the effects of the LWI for 3 months on MME and the Delta MME in each stage of OA.Methods: Participants were divided into three groups: no intervention with the LWI (control group; n = 9) and intervention with the LWI in early OA (early OA group: Kellgren-Lawrence (K/L) stage = 2, n = 17) and late OA (late OA group: K/L stage > 2, n = 13). MME was evaluated using ultrasound, and the Delta MME was obtained as the difference in MME from non-weight-bearing and weight-bearing conditions. These measurements were performed at two time points: the initial office visit as a baseline and post-3 months.Results: The weight-bearing MME and Delta MME values post-3 months were significantly decreased compared with those at baseline in the early OA group but not in the control or late OA groups.Conclusions: The use of the LWI for 3 months decreased weight-bearing MME and Delta MME values, and its effectiveness was more pronounced in the early stage of knee OA.
