■前交叉韧带重建(ACLR)继续与可变的运动恢复率和进一步的前交叉韧带损伤率相关。持续的功能缺陷可以解释这些结果,并支持需要不断探索下肢功能指标,尤其是在垂直跳跃时.这将有助于通过恢复运动连续体改善康复,并改善术后结果。
■ACLR后7个月患者的垂直跳跃表现指数受损。
■横断面研究;证据水平,3.
■共有202名接受ACLR的患者和50名健康参与者进行了单腿垂直跳跃(SLVJ)和单腿下降跳跃(SLDJ)测试。评估跳高(H)和反应强度指数(RSI),并比较两组之间每个参数的肢体对称指数(LSI)。还比较了健康参与者与ACLR患者的受伤和对侧腿之间的垂直跳跃指数。在两组中计算每个参数表现出LSI>90%的参与者的频率分析(卡方检验)。SLVJ-H之间的关联水平,SLDJ-H,和SLDJ-RSI使用皮尔逊系数(r)进行评估。
■术后6.6±0.7个月(平均值±SD),ACLR后的参与者在所有参数方面均表现出比对照组差的LSI(79.1±14.8vs93.9±4.5,77.3±14.6vs93.4±5.2和71.9±17.4vs93.4±3.8;所有P<.001;对于SLVJ-H,SLDJ-H,和SLDJ-RSI,分别)。与健康参与者相比,受伤和对侧腿的垂直跳跃表现均较低(所有P<.001)。只有27%,25%,16%的ACLR患者表现出SLVJ-H的LSI>90%,SLDJ-H,和SLDJ-RSI,分别,与80%相比,72%,对照组为86%。在ACLR组中,SLDJ-H与SLVJ-H之间(r=0.494;P<.001)以及SLDJ-RSI与SLVJ-H之间(r=0.488;P<.001)存在中等相关性。
■垂直跳跃指数(对称性和绝对值)在ACLR后7个月高度受损。反应强度能力的缺陷更为明显。临床医生应重点恢复垂直跳跃能力,以提高ACLR后的功能表现。
UNASSIGNED: Anterior cruciate ligament reconstruction (ACLR) continues to be associated with a variable rate of return to sports and a concerning rate of further anterior cruciate ligament injury. Persistent functional deficits may explain these results and support the need to keep exploring lower limb functional indexes, especially during vertical
jumping. This would help improve rehabilitation through the return-to-sports continuum and improve postoperative outcomes.
UNASSIGNED: Vertical
jumping performance indexes are impaired among patients 7 months after ACLR.
UNASSIGNED: Cross-sectional study; Level of evidence, 3.
UNASSIGNED: A total of 202 patients who underwent ACLR and 50 healthy participants performed single-leg vertical jump (SLVJ) and single-leg drop jump (SLDJ) testing. Jump height (H) as well as reactive strength index (RSI) were assessed and the limb symmetry index (LSI) of each parameter was compared between both groups. Vertical
jumping indexes were also compared between healthy participants and the injured and contralateral legs of ACLR patients. Frequency analysis (chi-square test) of participants exhibiting an LSI >90% for each parameter was calculated in both groups. The level of association between SLVJ-H, SLDJ-H, and SLDJ-RSI was evaluated using the Pearson coefficient (r).
UNASSIGNED: At 6.6 ± 0.7 months (mean ± SD) postoperatively, participants after ACLR exhibited poorer LSI than the control group for all parameters (79.1 ± 14.8 vs 93.9 ± 4.5, 77.3 ± 14.6 vs 93.4 ± 5.2, and 71.9 ± 17.4 vs 93.4 ± 3.8; all P < .001; for the SLVJ-H, SLDJ-H, and SLDJ-RSI, respectively). Vertical jumping performance was lower on both injured and contralateral legs compared with healthy participants (all P < .001). Only 27%, 25%, and 16% of the ACLR patients exhibited an LSI >90% for the SLVJ-H, SLDJ-H, and SLDJ-RSI, respectively, in comparison with 80%, 72%, and 86% in the control group. Moderate correlations were observed between SLDJ-H and SLVJ-H (r = 0.494; P < .001) as well as between SLDJ-RSI and SLVJ-H (r = 0.488; P < .001) in the ACLR group.
UNASSIGNED: Vertical
jumping indexes (both symmetry and absolute values) were highly impaired 7 months after ACLR. Deficits were more marked for reactive strength ability. Clinicians should focus on restoring vertical
jumping abilities to improve functional performance after ACLR.
