The present study sought to determine the influences of single-bundle (SB), single-bundle augmentation (SBA), and double-bundle (DB) reconstructions on balance ability and proprioceptive function.
67 patients who underwent a single- or double-bundle ACL reconstruction or a SBA using multistranded autologous hamstring tendons were included in this study with a 1-year follow-up. Body sway and knee kinesthesia (using the threshold to detect passive motion test (TTDPM)) were measured to indicate balance ability and proprioceptive function, respectively. Additionally, within-subject differences in anterior-posterior stability of the tibia and lower extremity muscle strength were evaluated before and after surgery.
At 6 and 12 months after surgery, DB reconstruction resulted in better balance and proprioceptive function than SB reconstruction (P < 0.05). Although no significant difference was observed in balance ability or proprioceptive function between the SBA and DB reconstructions, knee stability was significantly better with SBA and DB reconstructions than SB reconstruction (P < 0.05). No significant differences were found in quadriceps and hamstrings strength among the three reconstruction techniques.
Our findings consider that joint stability, proprioceptive function, and balance ability were superior with SBA and DB reconstructions compared to SB reconstruction at 6 and 12 months after surgery.
本研究旨在确定单束（SB）、单束增强（SBA）和双束（DB）重建对平衡能力和本体感觉功能的影响。
本研究纳入了67例行单束或双束前交叉韧带重建或使用多股自体腘绳肌腱进行单束增强术的患者，并进行了为期1年的随访。分别测量身体摇摆和膝关节感觉（使用被动运动检测阈值试验（TTDPM））来评估平衡能力和本体感觉功能。此外，还评估了手术前后胫骨前后稳定性和下肢肌肉力量的个体内差异。
术后6个月和12个月时，双束重建的平衡和本体感觉功能优于单束重建（P<0.05）。虽然单束增强重建和双束重建在平衡能力或本体感觉功能方面未观察到显著差异，但单束增强重建和双束重建的膝关节稳定性明显优于单束重建（P<0.05）。三种重建技术在股四头肌和腘绳肌力量方面未发现显著差异。
我们的研究结果认为，与单束重建相比，术后6个月和12个月时，单束增强重建和双束重建的关节稳定性、本体感觉功能和平衡能力更优。
