摘要
Purpose The correlation between tendon bone healing and clinical functional scores after anterior cruciate ligament reconstruction (ACLR) using four-stranded hamstring tendon autograft has rarely being reported. The purpose of this study was to determine the correlation between magnetic resonance imaging (MRI)-based tendon bone healing and clinical functional scores after ACLR using hamstring tendon. @@@ Methods Thirty-eight patients with ACLR using fourstranded hamstring tendon autograft were included in this prospective study in the authors' hospital from 2013 to 2014. All patients were performed Tegner, Lysholm, International Knee Documentation Committee (IKDC) subjective scores, KT-1000 and MRI examinations in 3, 6, 12 months after the operation, respectively. According to MRI, the healing degree of tendon bone was divided into five grades, and the healing degree of the tendon at different time points was evaluated. Moreover, the correlations between the clinical scores and tendon bone healing level at 12 months after the operation were determined. @@@ Results The Tegner, Lysholm, and IKDC scores of all patients were gradually improved over time after ACLR, and the degree of tendon bone healing was gradually increased. Moreover, there were significantly positive correlations between the level of tendon bone healing and the clinical functional scores at 12 months after the operation. @@@ Conclusion The clinical functional scores and the degree of tendon bone healing were gradually improved over time after ACLR. Moreover, there were significant positive correlations between the level of tendon bone healing and clinical functional scores of knee joint at the first year after the operation.
