Patients with a history of knee arthroplasty, septic arthritis or osteomyelitis of the knee, concomitant open or mini\u2010open procedures, or without information on resident involvement were excluded. A 1:1 propensity score match was performed based on age, sex, obesity, smoking history, and American Society of Anesthesiologist classification to match cases with resident involved to nonresident cases.
