Abstract

The incidence of total knee arthroplasty (TKA) in Canada is steadily escalating; however, some recipients do not experience optimal outcomes.

The objective of this study was to identify patient demographics associated with inferior pain and functional outcomes at 3-5years post-TKA. A secondary objective was to identify changes in physical activity between preoperative and 3-5 year post-TKA reports.

This was a secondary analysis of prospectively collected data of 743 TKA recipients. Univariate and multivariate analyses were performed for 3-5 year pain and functional outcomes on the Western Ontario McMaster Osteoarthritis Index (WOMAC).

Baseline variables significantly associated (p < 0.05) with 3-5 year WOMAC pain and function scores in the multivariate models were: age, BMI, back pain, WOMAC domain score, and SF-36 MH score. Daily activity and weekly walking levels tended to decrease after TKA.

Both pain and function models had low ability to predict outcomes, and sedentary activity increased post-TKA.
