Recently, a new technique, dynamic intraligamentary stabilization (DIS) was introduced for the acute repair of ACL ruptures. The purpose of this study was to report the functional recovery for patients undergoing acute anterior cruciate ligament (ACL) repair alongside DIS.
Forty five patients sustaining acute ACL rupture and treated with DIS repair were retrospectively evaluated. Limb symmetry index of the hop test as well as knee function by means of range of motion, knee swelling, pain and maximum strength were evaluated. Following completion of the rehabilitation program, the difference in anterior-posterior translation (Δ-AP Translation), IKDC, Tegner score (TAS) was additionally analyzed.
Forty five (13 females, 32 males) patients were included in the study. Mean age was 26years (range 18 to 54years). Median time to successfully complete hop test was 22.0weeks (range 11 to 32weeks) postoperatively. Median limb symmetry index 91.6%±8.3%. Median delta anterior-posterior translation compared to the healthy side was plus 0.0mm±1.6mm. Median IKDC was 89.5±6.5. Mean Tegner score (TAS) at 12months of follow-up was seven (range four to nine). Three patients suffered a rerupture during the first 12 postoperative months.
DIS technique with proper rehabilitation following acute ACL rupture provides successful functional recovery and low rerupture rate at one-year follow-up.
最近，一种新技术——动态韧带内稳定术（DIS）被引入用于急性前交叉韧带（ACL）断裂的修复。本研究的目的是报告接受急性ACL修复并联合DIS治疗的患者的功能恢复情况。
对45例急性ACL断裂并接受DIS修复治疗的患者进行回顾性评估。评估单腿跳测试的肢体对称指数以及通过活动范围、膝关节肿胀、疼痛和最大力量来评估膝关节功能。在康复计划完成后，还分析了前后向平移差异（Δ-AP平移）、国际膝关节文献委员会（IKDC）评分、泰格纳评分（TAS）。
45例（13例女性，32例男性）患者纳入研究。平均年龄26岁（范围18至54岁）。术后成功完成单腿跳测试的中位时间为22.0周（范围11至32周）。中位肢体对称指数为91.6%±8.3%。与健侧相比，中位前后向平移差异为+0.0mm±1.6mm。中位IKDC评分为89.5±6.5。随访12个月时的平均泰格纳评分（TAS）为7分（范围4至9分）。3例患者在术后12个月内再次断裂。
急性ACL断裂后采用DIS技术并进行适当康复，在一年随访时可实现成功的功能恢复且再断裂率低。
