Osteochondral Allograft MRI Scoring System in the Knee: Interobserver Agreement & Clinical Application

Purpose: To validate OCAMRISS for clinical use through the assessment of interobserver variability and to also determine which radiological features show correlation with clinical outcome.

Summary:

  • 15 patients underwent an OCA transplantation in the knee and received a MRI post-operatively
  • Four examiners evaluated each MRI and subsequently completed an OCAMRISS
  • Agreement amongst readers was very strong for cartilage, bone, ancillary and total scores as 96% of comparisons had an intraclass correlation coefficient ˃0.80
  • IKDC function scores correlated with cartilage and total scores, KOOS subscales correlated with the ancillary score
  • More study is necessary to recommend intervals for MRI assessment

Take Away: OCAMRISS is a reproducible grading system for the in vivo evaluation after OCA transplantation. Its use may provide a standardized method to communicate findings related to this procedure.
