The issue of apportionment of PD due to pre-existing osteoarthritis was again the subject of a WCAB decision in DURAZO v. SOLOMAN DENTAL CORP, 2020 Cal.Wrk.Comp.P.D.LEXIS__. In Durazo, the applicant had knee replacement surgery with a poor result. Two doctors found the PD was due solely to the work injury and poor surgery results while a QME found 50% apportionment to pre-existing osteoarthritis. The trial judge followed HIKDA and said no to apportionment. The WCAB concluded that the recent JUSTICE decision should be considered and sent the case back to the trial judge to find out whether the knee replacement surgery eliminated the pre-existing arthritis which could then eliminate any apportionment of PD. HIKADA and JUSTICE will continue to conflict with each other until the Cal legislature or Cal Supreme Court resolve the conflict over how to apply apportionment to PD caused by medical treatment of a work injury.
