We prospectively studied knee proprioception following ACL reconstruction in 40 patients (34 men and six women; mean age 31 years). The patients were allocated into two equal groups; group A underwent reconstruction using hamstrings autograft, and group B underwent reconstruction using bone-patellar tendon-bone autograft. Proprioception was assessed in flexion and extension by the joint position sense (JPS) at 15°, 45° and 75°, and time threshold to detection of passive motion (TTDPM) at 15° and 45°, preoperatively and at 3, 6 and 12 months postoperatively. The contralateral healthy knee was used as internal control. No statistical difference was found between the ACL-operated and the contralateral knees in JPS 15°, 45° and 75° at 6 and 12 months, in both study groups. No statistical difference was found between the ACL-operated and the contralateral knees in TTDPM 15° at 6 and 12 months, nor regarding TTDPM 45° at 3, 6 and 12 months, in group A. No statistical difference was found in JPS and TTDPM between the two grafts, at any time period. Knee proprioception returned to normal with ACL reconstruction at 6 months postoperatively, without any statistically significant difference between the autografts used.
我们对40例患者（34名男性和6名女性；平均年龄31岁）进行了前交叉韧带重建术后膝关节本体感觉的前瞻性研究。患者被平均分为两组；A组采用自体腘绳肌腱进行重建，B组采用自体骨-髌腱-骨进行重建。术前以及术后3个月、6个月和12个月，通过在15°、45°和75°时的关节位置觉（JPS）以及在15°和45°时检测被动运动的时间阈值（TTDPM），对屈伸时的本体感觉进行评估。对侧健康膝关节作为内部对照。在两个研究组中，术后6个月和12个月时，前交叉韧带手术侧膝关节与对侧膝关节在15°、45°和75°的JPS方面均未发现统计学差异。A组中，术后6个月和12个月时，前交叉韧带手术侧膝关节与对侧膝关节在15°的TTDPM方面未发现统计学差异，在术后3个月、6个月和12个月时，45°的TTDPM方面也未发现统计学差异。在任何时间段，两种移植物在JPS和TTDPM方面均未发现统计学差异。术后6个月时，前交叉韧带重建术后膝关节本体感觉恢复正常，所用自体移植物之间无任何统计学显著差异。
