目的:本研究旨在比较前交叉韧带重建1年后膝关节损伤和骨关节炎预后评分(KOOS)运动和娱乐(Sport/Rec)和生活质量(QoL)分量表(QoL)中发生和未发生最小重要变化(MIC)的患者的人口统计学和手术特征。
方法:比较横截面。
方法:从手术前到1年随访,KOOSSport/Rec子量表的MIC为≥12.1,KOOSQoL子量表的MIC为≥18.3。
方法:共纳入16131例患者:11172例(69%),Sport/Rec量表无MIC,生活质量为10641(66%)。
结果:对运动/Rec和QoL无MIC的患者的体重指数(BMI)较高(分别为24.8±3.5vs24.6±3.3和24.7±3.5vs24.6±3.2,p<0.0001),手术时年轻(岁)(分别为28.5±10.3vs29.1±10.8和27.4±9.8vs29.7±11.0,p=0.0002和<0.0001),从受伤到手术的时间更长(月)(Sports/Rec分别为22.0±38.5和19.3±36.6,p=0.0002),伴随软骨损伤的发生率更高,尤其是股骨外侧髁(22.7%vs19.4%和23.3%vs19.0%,分别,与达到MIC的患者相比,p=0.001和p=0.005)。与MIC患者(94.1%)相比,接受绳肌腱自体移植治疗的患者中没有MIC(91.4%)的比例较小。
结论:KOOSSport/Rec和QoL分量表没有MIC的患者的BMI较高,与达到MIC的患者相比,从受伤到手术的时间更长,手术时更年轻.虽然差异很小,他们可能会针对具有这些特征的患者重新制定管理策略.
OBJECTIVE: This study aimed to compare demographic and surgical characteristics between patients who do and do not achieve minimal important change (MIC) in the Knee injury and Osteoarthritis Outcome Score (KOOS) Sports and Recreation (Sport/Rec) and Quality of Life (QoL) subscales 1 year after anterior cruciate ligament reconstruction.
METHODS: Comparative cross-sectional.
METHODS: The MIC for the KOOS Sport/Rec subscale was ≥12.1 and ≥18.3 for the KOOS QoL subscale from before surgery to 1-year follow-up using data from the Swedish National Knee Ligament Registry.
METHODS: In total 16 131 patients were included: 11 172 (69%) with no MIC for the Sport/Rec scale, and 10 641 (66%) for the QoL.
RESULTS: Patients with no MIC for Sport/Rec and QoL had a higher body mass index (BMI) (24.8±3.5 vs 24.6±3.3 and 24.7±3.5 vs 24.6±3.2, respectively, p<0.0001), were younger (years) at time of surgery (28.5±10.3 vs 29.1±10.8 and 27.4±9.8 vs 29.7±11.0, respectively, p=0.0002 and <0.0001), had longer time from injury to surgery (months) (Sports/Rec 22.0±38.5 vs 19.3±36.6, respectively, p=0.0002), and greater rates of concomitant cartilage injuries especially to the lateral femoral condyle (22.7% vs 19.4% and 23.3% vs 19.0%, respectively, p=0.001 and p=0.005) compared with patients who achieved the MIC. A smaller proportion of patients treated with a hamstring tendon autograft had no MIC (91.4%) compared with patients with MIC (94.1%).
CONCLUSIONS: Patients with no MIC for KOOS Sport/Rec and QoL subscales had a higher BMI, longer time from injury to surgery and were younger at the time of surgery compared with patients who did achieve MIC. Although differences were small, they may reframe management strategies with patients who have these characteristics.
