Abstract
Our objectives were to assess relationships between self-reported questionnaires and 2-minute walk test (2MWT) and timed get-up-and-go test (TUG) in preoperative total hip arthroplasty patients. A total of 162 patients completed the Western Ontario and McMaster Universities Osteoarthritis Index and Short Form 36 and performed 2MWT and TUG. Correlations between self-reported questionnaires and 2MWT and TUG were mild to moderate, indicating that the 2MWT and TUG capture additional dimensions of preoperative total hip arthroplasty function not measured by the Western Ontario and McMaster Universities Osteoarthritis Index and Short Form 36. Use of walking aids, female sex, and presence of other painful joints were significantly associated with 2MWT, whereas older age and additional painful joints were significantly associated with TUG. These 2 tests are easy to perform in clinical practice and contribute to a comprehensive assessment of preoperative status.
