This case involved a custodian injured on the job, causing admitted industrial injury to her knee and lumbar spine. The Administrative Law Judge apportioned 50% of the permanent disability to pre-existing arthritis, a decision the applicant contested. The Workers' Compensation Appeals Board denied reconsideration, finding the apportionment supported by medical evidence indicating the industrial injury and pre-existing arthritis jointly necessitated knee replacement surgery. This aligns with precedent requiring apportionment to all causative factors, including underlying pathology.
