Forty-five patients with documented ACL injuries were examined objectively and subjectively to evaluate the effectiveness of the Lenox Hill brace in treating knee instability. The brace failed to significantly reduce maximal anterior subluxation of the tibia, but did increase resistance to displacement. Rotatory instability was improved an average of one grade by the brace, while varus/valgus laxity was unchanged. Subjectively, patients experienced a significant reduction in episodes of giving way, and athletic performance was improved by the brace in 69% of patients. Increased symptoms of instability correlated positively with greater measured laxity and low resistance to tibial displacement. The brace, while not effective in controlling absolute laxity, significantly reduced symptoms of instability in the nonelite athlete, possibly through increasing relative resistance to subluxation. Overall, 91% of the patients examined were satisfied with the brace and felt it was beneficial for them.
对45例有记录的前交叉韧带损伤患者进行了客观和主观检查，以评估Lenox Hill支具治疗膝关节不稳定的有效性。该支具未能显著减少胫骨最大前半脱位，但确实增加了对移位的阻力。支具使旋转不稳定平均改善了一级，而内翻/外翻松弛度未改变。主观上，患者感觉打软腿发作次数显著减少，69%的患者使用支具后运动表现得到改善。不稳定症状增加与更大的测量松弛度和对胫骨移位的低阻力呈正相关。该支具虽然在控制绝对松弛方面无效，但可能通过增加对半脱位的相对阻力，显著减轻了非精英运动员的不稳定症状。总体而言，91%接受检查的患者对该支具满意，并认为它对他们有益。
