Abstract

The number of total knee arthroplasty (TKA) procedures performed continues to rise. This is the first 1:1 matched cohort analysis of functional outcomes from a large prospective total joint registry. Our hypothesis is that a previous ipsilateral knee surgery is not associated with worse outcome scores following TKA. A total of 1,473 patients who underwent TKA were reviewed: 469 with a history of previous ipsilateral knee surgery and 1,004 without. After 1:1 matching, 469 patients were included in each cohort. Patients in both cohorts had statistically similar postoperative functional outcome scores, although patients without previous ipsilateral knee surgery had an increased Western Ontario and McMaster Universities Arthritis Index stiffness score. This study supports the hypothesis that previous ipsilateral knee surgery is not associated with worse functional outcomes following primary TKA.
