The anterior cruciate ligament (ACL) has both mechanical and proprioceptive (sensory) functions. Knee-joint proprioception has been assessed using either reproduction of position or threshold to detect passive motion in non-weight-bearing positions. It has been suggested that a more functional and dynamic/active assessment of proprioception might clarify the effects of injury and reconstruction on the proprioceptive function of ACL at the knee joint.
To assess knee joint position sense (JPS) following ACL reconstruction in functional positions.
Twelve male patients who had undergone ACL reconstruction and 12 male healthy control subjects participated in the study.
JPS was evaluated by reproduction of the angles in weight-bearing position with limb movement into flexion and extension. The dominant knee of healthy subjects and both (reconstructed and uninjured) knees of the patients were tested. Absolute angular error was used as a dependent variable.
There was no significant difference between the operated and uninjured knees of patients or between patients and healthy controls (p>or=0.05). These results were measured during two tasks of limb movement into flexion and extension.
We found no evidence of impaired JPS in weight-bearing positions in subjects with ACL reconstruction at a mean follow-up of 11 months after surgery compared with subjects with healthy knees.
前交叉韧带（ACL）具有机械和本体感觉（感觉）功能。膝关节本体感觉已通过在非负重位置重现位置或检测被动运动的阈值来评估。有人提出，对本体感觉进行更具功能性和动态/主动的评估可能会阐明损伤和重建对膝关节ACL本体感觉功能的影响。
评估功能性位置下ACL重建术后的膝关节位置觉（JPS）。
12名接受ACL重建的男性患者和12名健康男性对照受试者参与了该研究。
通过在负重位置重现肢体屈伸运动角度来评估JPS。测试了健康受试者的优势膝以及患者的双膝（重建膝和未受伤膝）。绝对角度误差用作因变量。
患者手术膝与未受伤膝之间或患者与健康对照之间均无显著差异（p≥0.05）。这些结果是在肢体屈伸两项任务期间测得的。
与健康膝关节受试者相比，我们发现术后平均随访11个月时，ACL重建受试者在负重位置下JPS无受损证据。
