The aim of this study was to test whether lesions of the medial meniscus (MM) and of the anterior cruciate ligament (ACL) are associated with specific abnormalities of isokinetic moment curves (IMCs). Fifty-four young adults (20 active healthy people, and 34 patients with unilateral knee injuries) were assessed through knee extensor and flexor isokinetic tests at 60°/s. Qualitative IMC analysis was performed using a novel classification system which identified three distinct abnormal shapes. The chi-squared (χ2) test was used to determine the inter-individual and intra-individual differences between the groups. Quantitative IMC inter-group comparisons were performed by a one-way analysis of variance (ANOVA). Knees with MM and ACL lesions were consistently associated with IMC shape irregularities (p<0.001) and with abnormal quantitative scores (p<0.001). More specifically, knees with isolated ACL lesions and knees with combined ACL and MM lesions presented similar distribution of knee extensor and flexor IMC irregularities, which was not present in knees with isolated MM lesions. A possible association between specific knee pathologies and IMC irregularities was identified (all p<0.05). In conclusion, different knee pathologies may be associated with different qualitative IMCs, which could be used as an additional presentation tool in clinical settings.
本研究的目的是测试内侧半月板（MM）损伤和前交叉韧带（ACL）损伤是否与等速力矩曲线（IMC）的特定异常有关。通过在60°/s下进行膝关节伸肌和屈肌等速测试，对54名年轻成年人（20名活跃健康者和34名单侧膝关节损伤患者）进行了评估。使用一种新的分类系统进行IMC定性分析，该系统识别出三种不同的异常形状。采用卡方（χ2）检验来确定组间和个体内差异。通过单因素方差分析（ANOVA）进行IMC组间定量比较。MM和ACL损伤的膝关节始终与IMC形状不规则（p<0.001）和异常定量评分（p<0.001）相关。更具体地说，孤立ACL损伤的膝关节和ACL与MM联合损伤的膝关节在膝关节伸肌和屈肌IMC不规则方面呈现相似的分布，而孤立MM损伤的膝关节则不存在这种情况。确定了特定膝关节病变与IMC不规则之间可能存在的关联（所有p<0.05）。总之，不同的膝关节病变可能与不同的定性IMC相关，这可作为临床环境中的一种额外展示工具。
