This study examined whether individuals undergoing total hip arthroplasty who are self-rated as “highly active”, demonstrated higher pre-operative activity levels than others. The positive correlation between subjective and objective measures of mobility increase our confidence in the latter as a valid indicator of the patient's preoperative activity level.

Aim

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 a 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 a valid indicator of the patient's preoperative activity level.
