目的：评估功能性膝关节支具对非手术急性前交叉韧带（ACL）缺陷患者的效果。设计：前瞻性随机临床试验。地点：大学诊所。患者：本研究纳入了 95 名患有急性 ACL 撕裂的患者（18-50 岁）。受试者被随机分配到支具组和对照组，前者从第一次测试期间（受伤后 5 周以内）到受伤后 12 周均接受功能性支具治疗，后者不接受支具治疗。对患者进行了为期 6 个月的随访。 21 名受试者因以下排除标准而被排除：MRI 或关节镜检查显示部分破裂或关节软骨损伤，或其他对康复产生负面影响的损伤，或因手术退出（n = 22）或个人原因（n = 10）。 42 名患者仍在研究中，其中 22 名患者在支具组，20 名患者在对照组。结果测量：视觉模拟量表、膝骨关节炎结果评分、辛辛那提膝关节评分、支具评估表和肌肉峰值扭矩。结果：使用视觉模拟量表评估时，使用支具组的受试者比对照组的不稳定感更少（P = 0.047）。然而，支具对膝骨关节炎结果评分或辛辛那提膝关节评分中的任何变量没有影响，对股四头肌或腿筋肌肉峰值扭矩没有影响。主观上，支具组体验到支具对康复的积极影响。结论：未手术的急性 ACL 缺陷患者在不稳定感和康复方面体验到支具的积极作用。然而，这些发现并没有得到客观结果的支持。
Objective:To evaluate the effect of a functional knee brace on nonoperated acute anterior cruciate ligament (ACL)-deficient patients. Design:Prospective randomized clinical trial. Setting:University clinic. Patients:Ninety-five patients (18-50 years old) with an acute ACL tear were included in the present study. The subjects were randomized to either brace group, treated with functional bracing from the first testing session (<5 weeks postinjury) to 12 weeks postinjury or a control group, treated without bracing. The patients were followed for 6 months. Twenty-one subjects were excluded due to the following exclusion criteria: partial rupture or articular cartilage injury shown on MRI or with arthroscopy, or other injuries that negatively affected rehabilitation, or dropped out due to surgery (n = 22), or personal reasons (n = 10). Forty-two patients remained in the study, 22 in the brace group and 20 in the control group. Outcome Measurements:Visual analogue scale, Knee Osteoarthritis Outcome Score, Cincinnati knee score, a brace evaluation form, and muscle peak torque. Results:When using the brace the subjects in the brace group experienced less (P = 0.047) sense of instability, evaluated with visual analogue scale, than the control group. However, bracing had no effect on any of the variables in Knee Osteoarthritis Outcome Score or Cincinnati knee score and no effect on quadriceps or hamstring muscle peak torque. Subjectively, the brace group experienced a positive effect of the brace on rehabilitation. Conclusions:Nonoperated acute ACL-deficient patients experienced a positive effect of the brace regarding sense of instability and rehabilitation. However, these findings were not supported by objective outcomes.
