Assessing Preoperative Mobility in Total Hip Arthroplasty: A SAFE T database study.

This study examined whether individuals undergoing total hip arthroplasty who are self-rated as "highly active", demonstrated higher pre-operative activity levels than others. METHODS: 483 patients were retrospectively identified; 241 were "highly active" and 242 were not. They were compared using WOMAC, self-reported activity and 6-Minute Walk Test (6MWT). RESULTS: Self-reported highly active adults demonstrated statistically significant higher WOMAC scores (48.85 vs 43.79), increased mean number of activities performed and mean 6MWT (348.14 m vs 274.64 m). CONCLUSIONS: The positive correlation between subjective and objective measures of mobility increase our confidence in the latter as valid indicator of patient's preoperative activity level.
