Abstract

Purpose

(1) To evaluate the relationship between the Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) 2.0 score and post-operative clinical outcomes following surgical repair of cartilage lesions in the tibiofemoral joint, and (2) to determine threshold values of the 1-year MOCART 2.0 score associated with favourable patient-reported outcome measures (PROMs).

Methods

Medical records of patients who underwent surgical repair for tibiofemoral joint cartilage lesions from 2010 to 2022 were retrospectively reviewed, and those who had magnetic resonance imaging and clinical assessments 1 year post-operatively were included. Outcomes were assessed using the International Knee Documentation Committee subjective score, Lysholm score and Knee Injury and Osteoarthritis Outcome Score (KOOS), with respective clinically important difference (CID) and substantial clinical benefit (SCB) values used to evaluate clinically significant improvement. Relationships between MOCART 2.0 scores and PROMs were analyzed, with cut-off values determined via receiver operating characteristic (ROC) analysis, followed by group comparisons.

Results

Eighty-six patients were included (mean age, 51.9 ± 14.3 years; males/females, 16/70; mean lesion size, 3.1 ± 1.5 cm²). The MOCART 2.0 score showed positive correlations with most PROMs at 1 year post-operatively. Logistic regression revealed significant associations between MOCART 2.0 scores and clinical improvements beyond CID and SCB values for the Lysholm score and SCB values for KOOS symptoms, which showed similar trends even when threshold values were adjusted by ±5 points in analyses. Subsequent ROC curve analyses identified statistically significant cut-off points ranging from 56 to 61 points. Comparative analysis, classified using a threshold of 60 considering its scoring system, demonstrated that patients with scores ≥60 showed generally higher PROMs and lower osteoarthritis grades at 1 year post-operatively and final follow-ups.

Conclusions

The MOCART 2.0 score, assessed 1 year after surgical repair for cartilage lesions in the tibiofemoral joint, positively correlates with PROMs, with scores of ≥60 expected to be associated with favourable clinical outcomes.

Level of Evidence

术后1年测量的MOCART 2.0评分为60分或更高，可预测手术修复胫股软骨病变后的良好临床结果。

目的：(1)评估软骨修复组织磁共振观察（MOCART） 2.0评分与胫股关节软骨病变手术修复术后临床结局的关系；(2)确定与患者报告的良好预后指标（PROMs）相关的1年MOCART 2.0评分的阈值。方法：回顾性分析2010 ~ 2022年行胫股关节软骨病变手术修复的患者病历，并纳入术后1年磁共振成像及临床评估的患者。结果采用国际膝关节文献委员会主观评分、Lysholm评分和膝关节损伤和骨关节炎结局评分（oos）进行评估，分别使用临床重要差异（CID）和实际临床获益（SCB）值来评估临床显著改善。分析MOCART 2.0评分与PROMs之间的关系，通过受试者工作特征（ROC）分析确定截断值，然后进行组间比较。结果：共纳入86例患者，平均年龄51.9±14.3岁，男女比例16/70，平均病变大小3.1±1.5 cm2。术后1年MOCART 2.0评分与大多数prom呈正相关。Logistic回归显示MOCART 2.0评分与Lysholm评分的CID和SCB值以及oos症状的SCB值之外的临床改善之间存在显著关联，即使在分析中将阈值调整±5点时也显示出相似的趋势。随后的ROC曲线分析确定了56到61点之间具有统计学意义的分界点。对比分析，考虑到评分系统，采用阈值60进行分类，结果表明，评分≥60的患者在术后1年和最后随访时，PROMs普遍较高，骨关节炎等级较低。结论：MOCART 2.0评分，在胫股关节软骨病变手术修复一年后评估，与PROMs呈正相关，评分≥60分预计与良好的临床结果相关。证据等级：四级。

期刊介绍： Few other areas of orthopedic surgery and traumatology have undergone such a dramatic evolution in the last 10 years as knee surgery, arthroscopy and sports traumatology. Ranked among the top 33% of journals in both Orthopedics and Sports Sciences, the goal of this European journal is to publish papers about innovative knee surgery, sports trauma surgery and arthroscopy. Each issue features a series of peer-reviewed articles that deal with diagnosis and management and with basic research. Each issue also contains at least one review article about an important clinical problem. Case presentations or short notes about technical innovations are also accepted for publication. The articles cover all aspects of knee surgery and all types of sports trauma; in addition, epidemiology, diagnosis, treatment and prevention, and all types of arthroscopy (not only the knee but also the shoulder, elbow, wrist, hip, ankle, etc.) are addressed. Articles on new diagnostic techniques such as MRI and ultrasound and high-quality articles about the biomechanics of joints, muscles and tendons are included. Although this is largely a clinical journal, it is also open to basic research with clinical relevance. Because the journal is supported by a distinguished European Editorial Board, assisted by an international Advisory Board, you can be assured that the journal maintains the highest standards. Official Clinical Journal of the European Society of Sports Traumatology, Knee Surgery and Arthroscopy (ESSKA).
