      Multicenter Reliability Study.

AB  - BACKGROUND: Several systems have been proposed for classifying osteochondritis 
      dissecans (OCD) of the knee during surgical evaluation. No single classification 
      includes mutually exclusive categories that capture all of the salient features 
      of stability, chondral fissuring, and fragment detachment. Furthermore, no study 
      has assessed the reliability of these classification systems. PURPOSE: To 
      determine the intra- and interobserver reliability of a novel, comprehensive 
      arthroscopic classification system with mutually exclusive OCD lesion types. 
      STUDY DESIGN: Cohort study (diagnosis); Level of evidence, 3. METHODS: The 
      Research in OsteoChondritis of the Knee (ROCK) study group developed a 
      classification system for arthroscopic evaluation of OCD of the knee that 
      includes 6 arthroscopic categories-3 immobile types and 3 mobile types. To 
      optimize comprehensibility and applicability, each was developed with a memorable 
      name, a brief description, a line diagram corresponding to the archetypal 
      arthroscopic appearance, and an arthroscopic photograph depicting this archetype. 
      Thirty representative arthroscopic videos were evaluated by 10 orthopaedic 
      surgeon raters, who classified each lesion. After 4 weeks, the raters again 
      classified the OCD lesions depicted in the 30 videos in a new, randomly selected 
      order. Reliability was assessed via the intraclass correlation coefficient (ICC). 
      RESULTS: The interobserver reliability of this novel arthroscopy classification 
      was estimated by an ICC of 0.94 (95% CI, 0.91-0.97) for the first round and 0.95 
      (95% CI, 0.93-0.98) for the second round. According to the standards for the 
      magnitude of the reliability coefficient of Altman, these ICCs indicate that 
      interobserver reliability was very good. The intraobserver reliability was 
      estimated by an ICC of 0.96 (95% CI, 0.95-0.97), which indicates that the 
      intraobserver reliability was similarly very good. CONCLUSION: The ROCK OCD knee 
      arthroscopy classification system demonstrated excellent intra- and interobserver 
      reliability. In light of this reliability, this classification system may be used 
      clinically and to facilitate future research, including multicenter studies for 
      OCD.
