Patient Scores and Functional Tests After Hip Surgery

Hip replacement surgery is generally effective in reducing pain and restoring movement in patients with hip joint problems. Despite the success of the procedure, some individuals continue to report dissatisfaction due to lingering discomfort or limitations in daily activities. A potential reason for this is the gap between how patients perceive their recovery and their actual physical function.

To better understand this issue, the study evaluates two types of assessment tools. The first group includes patient-reported outcome measures (PROMs), which rely on individuals' personal impressions of their symptoms and abilities. The second group involves physical performance tests that measure mobility and balance under clinical supervision.

Fifty patients who had hip replacement surgery at least six months earlier will take part in the study. Each participant will complete standardized questionnaires and undergo a series of physical tests during one clinic visit. The relationship between the two types of assessments will be analyzed using correlation and regression methods.

This research may help improve follow-up care by identifying whether patient questionnaires alone are sufficient to monitor recovery, or if performance-based tests should also be routinely included in rehabilitation planning.
