Background: The primary aim of this study was to assess whether patients dissatisfied with both recreational activities and overall outcome were different to those dissatisfied with recreational activities but satisfied with their overall outcome one year after total knee arthroplasty (TKA). Methods: A retrospective cohort consisting of 3324 primary TKA were identified from an established arthroplasty database. Patient demographics, comorbidities, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Short Form (SF) 12 scores were collected pre-operatively and one year post-operatively. Overall patient satisfaction and satisfaction with recreational activities were assessed at one year. Results: The rate of patient satisfaction with recreational activities (n = 2672, 80.4%) was significantly (odds ratio (OR) 0.47, 95% confidence intervals (CI) 0.41 to 0.54, p < 0.001) lower than satisfaction with the overall outcome (n = 2982, 89.7%). When adjusting for confounding variables older age (OR 1.03, p = 0.008), increasing BMI (OR 1.05, p = 0.01) and absence of hypertension (OR 0.66, p = 0.02) were independent predictors of being dissatisfied with recreational activities in isolation. The one-year components and total WOMAC scores were significant (p < 0.001) predictors of satisfaction with recreational activities and were reliable with an area under the curve of ≥ 0.82 Conclusion: Patients of older age, higher BMI and without hypertension are more likely to be dissatisfied with recreational activities despite being satisfied with their overall outcome.
