We aimed to report the trajectory of self‐reported outcomes up to 11 years post‐ACLR. We also explored the relationship between hop performance at 1 year and: (i) future self‐reported knee outcomes; and (ii) risk of subsequent knee events. 124 participants (43 women, mean age 31 ± 8 years) were recruited at 1 year following hamstring‐autograft ACLR. Hop performance was assessed with single‐forward and side‐hop tests. Follow‐up was completed at 3 (n = 114), 5 (n = 89) and 11 years (n = 72) post‐ACLR. Self‐reported outcomes were assessed at each follow‐up with the Knee injury Osteoarthritis Outcome Score (KOOS) pain and quality of life (QOL) subscales. Generalized linear mixed models estimated the relationship between hop performance and self‐reported outcomes. Subsequent knee events (new injury/surgery) to either knee were recorded, with the relationship between hop performance and risk of subsequent knee events analyzed with Cox proportional hazards. Self‐reported knee outcomes were stable (mean change < 10 points) across all timepoints but with major within‐sample variability. There was a modest relationship between greater hop performance at 1 year and better future KOOS‐pain (average marginal effect [AME] % improvement with + 1 cm single forward hop = 0.06% [95% CI 0.02–0.10]). A nonlinear spline relationship showed better single‐forward hop performance was associated with better KOOS‐QOL for scores < 108 cm, not present for higher hop scores > 108 cm. There were 21 index and 11 contralateral subsequent knee events. Hop performance was not related to risk of a subsequent knee event (hazard ratio index knee 0.99 [95% CI 0.98–1.02]). In conclusion, self‐reported knee pain and quality of life were generally stable across the 11‐year follow‐up period. Greater hop performance at 1‐year post‐ACLR was related to better self‐reported knee outcomes up to 11‐year follow‐up (of questionable clinical importance), but not associated with the risk of subsequent knee injury/surgery.

人们的变异性比跳跃测试显示的要大：ACL 重建后 11 年内的跳跃表现和自我报告的结果


我们的目标是报告 ACLR 后 11 年内自我报告结果的轨迹。我们还探讨了一年时的跳跃表现与以下因素之间的关系：（i）未来自我报告的膝盖结果； (ii) 随后发生膝关节事件的风险。在自体腘绳肌腱移植 ACLR 术后 1 年招募了 124 名参与者（43 名女性，平均年龄 31 ± 8 岁）。通过单向前和侧跳测试评估跳跃性能。随访在 ACLR 术后 3 年（n = 114）、5 年（n = 89）和 11 年（n = 72）完成。每次随访时均使用膝损伤骨关节炎结果评分 (KOOS) 疼痛和生活质量 (QOL) 子量表对自我报告的结果进行评估。广义线性混合模型估计了啤酒花表现和自我报告结果之间的关系。记录任一膝盖的后续膝盖事件（新伤/手术），并使用 Cox 比例风险分析跳跃表现与后续膝盖事件风险之间的关系。自我报告的膝关节结果在所有时间点都是稳定的（平均变化 < 10 分），但样本内存在较大差异。 1 年时更好的跳跃表现和更好的未来 KOOS 疼痛之间存在适度的关系（+ 1 cm 单向前跳跃的平均边际效应 [AME]% 改善 = 0.06% [95% CI 0.02–0.10]）。非线性样条关系表明，对于分数 < 108 cm，更好的单向前跳跃性能与更好的 KOOS-QOL 相关，但对于更高的跳跃分数 > 108 cm 则不存在。随后发生了 21 例指数膝关节事件和 11 例对侧膝关节事件。跳跃表现与随后发生膝关节事件的风险无关（膝关节风险比指数 0.99 [95% CI 0.98–1.02]）。总之，在 11 年的随访期间，自我报告的膝盖疼痛和生活质量总体稳定。 ACLR 后 1 年的更好的跳跃表现与 11 年随访期间自我报告的更好的膝关节结果相关（临床重要性值得怀疑），但与随后膝关节损伤/手术的风险无关。
