Girth measures are commonly used to assess muscle atrophy or joint effusion. Little is known, however, regarding girth measurement changes following knee injury and subsequent surgery. Therefore, the purpose of this study was to compare the thigh and calf girth measurements of involved and noninvolved extremities prior to and following knee surgery for subjects with acute and chronic knee injuries. Of the 40 subjects that were studied, 22 subjects were placed in the acute group (less than 6 months from time of injury to presurgery measurement) and 18 subjects were placed in the chronic group (greater than 6 months from time of injury to presurgery measurement). Thigh and calf girth measurements were taken prior to surgery and then prior to the initiation of outpatient rehabilitation following surgery. For the acute and chronic groups, a three-way analysis of variance (ANOVA) with repeated measures on the extremity, muscle, and time factors was used to analyze the data. For each group, the three-way ANOVA revealed a significant two-way interaction between the extremity and time factors. Post hoc analysis revealed significant differences between involved and noninvolved extremities at both the pre- and post-surgery time periods for the acute and chronic groups. While thigh and calf girth measurement differences existed between the involved and noninvolved extremities prior to and after surgery, the bulk of the girth measurement differences existed prior to surgery for both groups. Based upon the results of this study, the assessment and rehabilitation of the thigh and calf following knee injury and surgery are recommended.
围度测量通常用于评估肌肉萎缩或关节积液。然而，对于膝关节损伤及后续手术后围度测量的变化却知之甚少。因此，本研究的目的是比较急性和慢性膝关节损伤患者在膝关节手术前后患侧与非患侧大腿和小腿的围度测量值。在研究的40名受试者中，22名受试者被归入急性组（从受伤到术前测量的时间少于6个月），18名受试者被归入慢性组（从受伤到术前测量的时间大于6个月）。在手术前以及术后开始门诊康复治疗前测量大腿和小腿围度。对于急性组和慢性组，采用三因素重复测量方差分析来分析数据，这三个因素分别是肢体、肌肉和时间。对于每组，三因素方差分析显示肢体和时间因素之间存在显著的双向交互作用。事后分析显示，急性组和慢性组在手术前和手术后，患侧与非患侧肢体之间均存在显著差异。虽然手术前后患侧与非患侧肢体的大腿和小腿围度测量值存在差异，但两组围度测量值的大部分差异在手术前就已存在。基于本研究结果，建议对膝关节损伤和手术后的大腿和小腿进行评估和康复治疗。
