However, the incidence of early-onset OA remains higher in patients following ACLR. The purpose of this study was to compare the computed tibiofemoral joint (TFJ) forces and muscle forces of ACLR knees to those of BMI-matched control subjects during the stance phase of gait. We hypothesized that the use of principal component analysis would allow us to characterize alterations in three-dimensional TFJ loads and muscle forces after ACLR as compared to a healthy control population. Of the eight ACLR knees, four displayed an abnormal TFJ compressive force. In three of these four ACLR knees that displayed abnormal compressive forces, one of the major muscles/muscle groups crossing the knee also deviated from the control group. We believe that each subject has a unique response to their injury, reconstructive surgery, and rehabilitation.展开更多
文摘目的:探讨韧带倾斜角及胫股关节角度变化与前交叉韧带重建关节功能的关系及影响因素。方法:选取2021年3月至2023年3月在洛阳正骨医院膝关节中心进行前交叉韧带重建治疗的患者102例,根据术后6个月国际膝关节文献委员会(international knee joint literature committee,IKDC)评分情况分为关节功能恢复良好患者72例和关节功能恢复不良患者30例,比较恢复良好和不良患者临床资料、韧带倾斜角及胫股关节角度变化,并分析与前交叉韧带重建关节功能的关系及其影响因素。结果:关节功能恢复不良患者女性比例、年龄≥40岁比例、生活意外比例分别为56.67%、60.00%和73.33%,明显高于关节功能恢复良好患者(P<0.05);关节功能恢复不良患者前交叉韧带冠状位、矢状位倾斜角手术前后变化值分别为(16.78±1.88)°和(16.20±1.82)°,明显高于恢复良好患者(P<0.05);关节功能恢复良好和不良患者胫股关节角度手术前后变化值比较差异无统计学意义(P>0.05);前交叉韧带冠状位、矢状位倾斜角手术前后变化值与IKDC评分呈负相关(r=-0.399;-0.454,P<0.05);胫股关节角度手术前后变化值与IKDC评分无明显相关性(P>0.05);Logistic回归分析结果显示:年龄、前交叉韧带冠状位倾斜角手术前后变化值、前交叉韧带矢状位倾斜角手术前后变化值是患者关节功能恢复的影响因素(P<0.05)。结论:年龄及韧带倾斜角手术前后变化值是前交叉韧带重建关节功能的影响因素,胫股关节角度变化与关节功能恢复无明显相关性。
