Muscle weakness due to trauma from the surgical approach is
anticipated to affect the ability of the patient to undertake daily physical
activity early after total hip arthroplasty (THA).
The objective of this study
was to compare daily physical activity on days 1 to 4 after discharge, in
patients following THA performed by 1 of 3 surgical approaches. DESIGN: A cohort
study included 60 hip osteoarthritis patients, scheduled for THA, allocated to
direct lateral approach, posterior approach, or anterior approach. Daily physical
activity was measured by an accelerometer, with upright time per 24 hours as
primary outcome and walking time, number of steps, and number of upright events
per 24 hours as secondary outcomes. RESULTS: There were no statistically
significant group differences in any of the measures of daily physical activity
(P > 0.290) or between days of follow-up (P > 0.155). Overall, the median
participant had 3.50 hours (interquartile range, 2.85-4.81 hours) of upright
time, and participants showed wide variation in all outcomes of daily physical
activity. CONCLUSIONS: There were no differences in daily physical activity
between THA patients undergoing different surgical approaches. The surgical
approach may not be a limiting factor for daily physical activity early after
surgery in a fast-track treatment course.
