保守治疗失败是重建前交叉韧带(ACL)缺乏的膝关节的常见指征，这取决于主观判断。肌肉通过反射收缩保护半脱位关节的能力可以提供客观的测量。我们通过测量反射肌腱收缩的潜伏期对30例单侧前交叉韧带缺乏症患者进行了研究。我们发现，患肢的平均潜伏期几乎是健肢的两倍(分别为99ms和53ms)。差异潜伏期和让路频率之间存在显著的相关性，这表明功能不稳定的部分原因可能是本体感觉的丧失。本体感觉的测量，包括反射腿筋潜伏期，可能有助于客观评估保守治疗的疗效和手术的必要性。
Failure of conservative treatment is the usual indication for the reconstruction of a knee with deficiency of the anterior cruciate ligament (ACL) and this depends on subjective judgement. The ability of muscles to protect the subluxing joint by reflex contraction could provide an objective measurement.We have studied 30 patients with unilateral ACL deficiency by measuring the latency of reflex hamstring contraction. We found that the mean latency in the injured leg was nearly twice that in the unaffected limb (99 ms and 53 ms respectively).There was a significant correlation between the differential latency and the frequency of 'giving way' indicating that functional instability may be due, in part, to loss of proprioception. Measures of proprioception, including reflex hamstring latency, may be useful in providing an objective assessment of the efficacy of conservative treatment and the need for surgery.
