ACL重建术后5年ACL-RSI评分与患者报告结局相关
简介
该研究回顾性分析了471例前交叉韧带（ACL）重建术后患者（平均随访4.9年），评估术后约5年时的ACL-RSI评分与中期功能结局（IKDC、自我膝关节价值（SKV）和Tegner活动评分）的关联。关键发现：ACL-RSI评分与IKDC（r=0.67）和SKV（r=0.59）呈中高度相关，与Tegner评分相关性较低（r=0.34）；多变量回归分析证实ACL…
英文摘要
BACKGROUND: Psychological factors influence recovery after Anterior Cruciate Ligament (ACL) reconstruction. While the ACL Return to Sport after Injury (ACL-RSI) score is widely used during early follow-up, its clinical relevance at mid-term follow-up remains unclear. PURPOSE: To evaluate the association between ACL-RSI scores measured at approximately five years after ACL reconstruction and patient-reported outcomes at mid-term follow-up. METHODS: A retrospective analysis of a prospectively collected cohort was performed. Patients who underwent primary ACL reconstruction between January 2017 and December 2019 and completed the ACL-RSI questionnaire at approximately five-year follow-up were included. Functional outcomes assessed at final follow-up included the subjective International Knee Documentation Committee (IKDC) score, Self Knee Value (SKV), and Tegner activity scale. Associations were analyzed using Spearman correlation coefficients and further assessed using multivariable linear regression models adjusting for potential confounders. RESULTS: A total of 471 patients were included, with a mean follow-up of 4.9 ± 1.2 years. ACL-RSI scores showed moderate-to-high correlations with IKDC (r = 0.67, p < 0.001) and SKV (r = 0.59, p < 0.001), and a lower correlation with the Tegner activity scale (r = 0.34, p < 0.001). In multivariable analyses, ACL-RSI remained independently associated with all functional outcomes (all p < 0.001). ACL-RSI scores were significantly higher at mid-term follow-up compared with six months postoperatively (70 ± 25 vs 65 ± 19; p < 0.001), corresponding to a modest mean increase of 5 points. CONCLUSION: Psychological readiness assessed by the ACL-RSI remains significantly associated with patient-reported knee function and activity level at mid-term follow-up after ACL reconstruction. LEVEL OF EVIDENCE: IV; retrospective cohort study.
