OBJECTIVE: To determine which patient characteristics, postoperative
characteristics, and walking features influence patients' partial weight-bearing
performance after total hip arthroplasty. DESIGN: A descriptive prospective
study. PATIENTS: Fifty patients with total hip arthroplasty were included;
partial weight-bearing was performed at a 10% body weight target load (n=33) and
at a 50% body weight target load (n=17). METHODS: Patient (age, gender, body
weight, upper arm muscle strength) and postoperative (pain, fatigue, anxiety)
characteristics, and walking features (step frequency, total walking time, total
number of steps, walking aid) were measured postoperatively on day 7 (with and
without a physical therapist) and on day 21 (at home). Multilevel regression
analyses were conducted to identify determinants that influence partial
weight-bearing. RESULTS: Gender (female) (regression coefficient B=8.18, p=0.03)
and total walking time (B=0.58, p<0.001) were positively, and pain during walking
was negatively (B=-2.43, p=0.02), associated with the mean peak load. For partial
weight-bearing at 10% body weight, postoperative overall anxiety (B=6.40,
p=0.002) and total steps (B=0.05, p=0.02) were positively associated with the
percentage of steps above the target load. For partial weight-bearing at home,
postoperative overall anxiety was negatively associated with the percentage of
steps above the target load (B=-5.32, p=0.001). Conclusion: Gender, pain during
walking, walking time, postoperative anxiety and total number of steps influence
the patient's partial weight-bearing performance.
