The rule of no thumb test was compared with the towel clip test in determining the need for lateral retinacular release in 200 consecutive primary total knee replacements. The towel clip test was positive in 13 knees (6.5%) and the rule of no thumb test was positive in 78 knees (39%). Using a positive towel clip test as the indication for lateral retinacular release, there was no radiographic evidence of patellar tilt, subluxation, or dislocation in any knee at 6 months postoperatively. Therefore, the rule of no thumb test falsely predicted the need for lateral release in 65 knees (32.5%). The authors advocate the towel clip test to determine the need for lateral retinacular release.
在200例初次全膝关节置换术中，将无拇指试验与巾钳试验进行比较，以确定是否需要进行外侧支持带松解。巾钳试验在13例膝关节中呈阳性（6.5%），无拇指试验在78例膝关节中呈阳性（39%）。以巾钳试验阳性作为外侧支持带松解的指征，术后6个月时，所有膝关节均无髌骨倾斜、半脱位或脱位的影像学证据。因此，无拇指试验在65例膝关节中（32.5%）错误地预测了外侧松解的必要性。作者提倡使用巾钳试验来确定是否需要进行外侧支持带松解。
