We conducted a prospective, randomized study of open and closed kinetic chain exercises during accelerated rehabilitation after anterior cruciate ligament reconstruction to determine if closed kinetic chain exercises are safe and if they offer any advantages over conventional rehabilitation. The closed kinetic chain group used a length of elastic tubing, the Sport Cord, to perform weightbearing exercises and the open kinetic chain group used conventional physical therapy equipment. Results are reported with a minimum 1-year followup (mean, 19 months). Pre- and postoperative evaluation included the Lysholm knee function scoring scale, Tegner activity rating scale and KT-1000 arthrometer measurements. Overall, stability was restored in over 90% of the knees. Preoperative patellofemoral pain was reduced significantly; 95% of the patients had a full range of motion. The closed kinetic chain group had lower mean KT-1000 arthrometer side-to-side differences, less patellofemoral pain, was generally more satisfied with the end result, and more often thought they returned to normal daily activities and sports sooner than expected. We concluded that closed kinetic chain exercises are safe and effective and offer some important advantages over open kinetic chain exercises. As a result of this study, we now use the closed kinetic chain protocol exclusively after anterior cruciate ligament reconstruction.
我们进行了一项前瞻性随机研究，比较前交叉韧带重建术后加速康复期间开放动力链运动与闭合动力链运动，以确定闭合动力链运动是否安全，以及与传统康复方法相比是否具有优势。闭合动力链组使用一段弹力管（Sport Cord）进行负重运动，开放动力链组使用传统物理治疗设备。报告的结果是在至少1年的随访期（平均19个月）后得出的。术前和术后评估包括Lysholm膝关节功能评分量表、Tegner活动评级量表和KT-1000关节测量仪测量。总体而言，超过90%的膝关节恢复了稳定性。术前髌股关节疼痛明显减轻；95%的患者关节活动范围正常。闭合动力链组的KT-1000关节测量仪两侧差异均值更低，髌股关节疼痛更少，总体上对最终结果更满意，并且更多人认为他们比预期更早恢复日常活动和运动。我们得出结论，闭合动力链运动安全有效，与开放动力链运动相比具有一些重要优势。基于这项研究的结果，我们现在在前交叉韧带重建术后仅使用闭合动力链方案。
