背景本研究的目的是确定当前的术后康复方案是否可以使前十字韧带 (ACL) 重建后对侧未受伤肢体膝关节屈肌和伸肌的力量恢复到未受伤对照组的强度。方法。将进行腘绳肌腱 ACL 重建的受试者 (n = 12) 与活性对照组 (n = 30) 进行比较。进行了全面的双侧膝关节屈肌和伸肌等速力量测试（五种速度、5-95 度、同心和偏心收缩）。结果。腘绳肌腱 ACL 重建和康复后，双侧力量正常化（对侧肢体的 10% 以内）是通过膝关节伸肌而不是膝屈肌实现的。与未受伤的对照组相比，重建的前交叉韧带（伸肌 24.8%；屈肌 26.8%）和未受伤的对侧肢体（伸肌 21%；屈肌 13.5%）的膝伸肌和膝屈肌均表现出较大且具有统计学意义的力量缺陷。这些发现表明，ACL 重建后膝关节屈肌康复可以得到改善，并限制了使用对侧腿作为 ACL 重建人群的康复终点或对照的有效性。 (C) 2007 Elsevier Ltd. 保留所有权利。
Background The purpose of this study was to determine whether current post-operative rehabilitation protocols return the strength of the contralateral uninjured limb knee flexors and extensors after an anterior cruciate ligament (ACL) reconstruction to those of an uninjured control group.Methods. Subjects with a hamstring tendon ACL reconstruction (n = 12) were compared to an active control group (n = 30). Comprehensive bilateral knee flexor and extensor isovelocity strength testing was performed (five speeds, 5-95 degrees, concentric and eccentric contractions).Findings. After hamstring tendon ACL reconstruction and rehabilitation, bilateral strength normalization (within 10% of the contralateral limb) is achieved by the knee extensors but not the knee flexors. When compared to the uninjured control group, large and statistically significant strength deficits were demonstrated in the knee extensors and knee flexors of both the anterior cruciate ligament reconstructed (extensors 24.8%; flexors 26.8%) and the contralateral uninjured (extensors 21%; flexors 13.5%) limbs.Interpretation. These findings suggest that improvement can be made in knee flexor rehabilitation after ACL reconstruction and limit the validity of the use of a contralateral leg as a rehabilitation endpoint or as a control in the ACL reconstructed population.
