Acute and chronic cartilage injury of the knee has an important impact on prognosis. The validity of the classification of such injuries is critical for prospective multicenter studies. The agreement among multiple surgeons at different institutions for articular cartilage lesions has not been established.
Arthroscopic classification of articular cartilage lesions is reliable and reproducible and can be used for multicenter studies involving multiple surgeons.
Cohort study (diagnosis); Level of evidence, 1.
A total of 6 surgeons from 5 centers reviewed 31 videos of articular cartilage lesions. With grade 2 and grade 3 combined for the analysis, observed agreement ranged from 81% to 94%, and kappa ranged from 0.34 to 0.87. An additional 22 videos comprising grade 2 and grade 3 lesions were analyzed, and the observed agreement was 80%, with an overall kappa of 0.47.
Arthroscopic grading of articular cartilage lesions is reproducible among surgeons at different centers.
Articular cartilage lesions can be reliably classified among surgeons at different sites. Such reliability is important for multicenter clinical research studies involving arthroscopic knee surgery.
膝关节急性和慢性软骨损伤对预后有重要影响。此类损伤分类的有效性对于前瞻性多中心研究至关重要。不同机构的多位外科医生对关节软骨损伤的一致性尚未确立。
关节软骨损伤的关节镜分类可靠且可重复，可用于涉及多位外科医生的多中心研究。
队列研究（诊断）；证据等级，1级。
来自5个中心的6位外科医生对31段关节软骨损伤视频进行了评估。将2级和3级合并进行分析，观察到的一致性范围为81%至94%，kappa值范围为0.34至0.87。另外对包含2级和3级损伤的22段视频进行了分析，观察到的一致性为80%，总体kappa值为0.47。
不同中心的外科医生对关节软骨损伤的关节镜分级具有可重复性。
不同部位的外科医生能够可靠地对关节软骨损伤进行分类。这种可靠性对于涉及膝关节镜手术的多中心临床研究很重要。
