This study evaluated countermovement jump and Single Leg Jump measures to identify landing measures that best distinguish a novel Anterior Cruciate Ligament reconstruction technique using bone marrow aspirate, demineralized bone matrix, and suture tape augmentation patients from controls. The secondary objective assessed performance differences between operated and non-operated limbs post-reconstruction. The hypothesis was that novel Anterior Cruciate Ligament reconstruction patients at return to sport would not differ from controls during landing and that the operated limb's performance would not differ from the unoperated limb.
The study included 31 patients with the novel reconstruction technique matched with controls in a 1:10 ratio based on age, sex, weight, and height. Both groups underwent screening and were compared during a Countermovement Jump. Using a Sparta Science Force Platform, each patient's unoperated and operated limbs were also compared for Single Leg Jump post-op (6.5 months).
Test patients showed no difference in center of pressure during landing of both jumps compared to controls (P=0.27) and the uninvolved limb (P=0.26). Test patients exhibited increased braking impulse relative to the uninvolved limb during Single Leg Jump (P<0.001). Deceleration upon landing of Countermovement Jump was also increased compared to controls (P<0.001). Test patients demonstrated slower concentric time during a Countermovement Jump compared to controls (P=0.03) and significantly slower compared to the uninjured leg (P<0.001). Countermovement Jump height was decreased compared to controls (P<0.001). Single-leg jump height was decreased in the injured limb compared to the uninjured limb (P<0.001).
Test patients did not show significant differences in landing motion compared to controls or the uninvolved leg. However, power and performance alterations were evident at Return to Sport after reconstruction. Although these results are quite promising, they may be too preliminary to draw definitive conclusions. Double and single-legged assessments should be considered in return-to-sport decision-making.
本研究评估了反向跳和单腿跳测量方法，以确定能最佳区分采用骨髓抽吸物、脱矿骨基质和缝线带增强技术进行新型前交叉韧带重建的患者与对照组的落地测量指标。次要目的是评估重建后手术侧肢体与非手术侧肢体的性能差异。假设是新型前交叉韧带重建患者恢复运动时在落地过程中与对照组无差异，且手术侧肢体的表现与未手术侧肢体无差异。
本研究纳入了31例采用新型重建技术的患者，根据年龄、性别、体重和身高以1:10的比例与对照组进行匹配。两组均接受筛查，并在反向跳过程中进行比较。使用斯巴达科学力平台，还对每位患者术后6.5个月的非手术侧和手术侧肢体进行单腿跳比较。
与对照组相比（P = 0.27）以及与未受累肢体相比（P = 0.26），测试患者在两次跳跃落地时的压力中心无差异。在单腿跳过程中，测试患者相对于未受累肢体表现出更大的制动冲量（P < 0.001）。与对照组相比，反向跳落地时的减速也增加了（P < 0.001）。与对照组相比，测试患者在反向跳过程中的向心时间较慢（P = 0.03），与未受伤腿相比明显更慢（P < 0.001）。与对照组相比，反向跳高度降低（P < 0.001）。与未受伤肢体相比，受伤肢体的单腿跳高度降低（P < 0.001）。
与对照组或未受累腿相比，测试患者在落地动作上没有显著差异。然而，重建后恢复运动时，力量和性能改变是明显的。尽管这些结果很有前景，但可能还过于初步，无法得出明确结论。在恢复运动的决策中应考虑双腿和单腿评估。
