A novel OA grading scheme developed by OAISYS was used in two research projects which were presented at OARSI 2013

The first projects principal investigator, Lisa Sheehy, examines the reliability of the Uni-Compartmental Osteoarthritis Grading scheme (UCOAG) using data from the multicenter osteoarthritis study (MOST) database. The data indicate high inter and intra reader reliability with excellency retest results. The scheme is considered more sensitive than the current Kelgren Lawrence scheme.

The second projects principal investigator, Dr. Mark Harrison, investigates the relationship for use of the UCOAG and disability index as a triage mechanism for knee replacement surgery. The data suggest promise as the basis for a reliable evidence based triage mechanism.
