he Difference Between Actual and Prescribed Weight earing of Total Hip Patients With a Trochanteric Osteotomy: ong-Term Vertical Force Measurements Inside and Outside he Hospital

Objective: To determine whether patients load the operated eg at a prescribed weight-bearing target load during postoprative recovery. Design: A descriptive prospective study. Setting: Orthopedic clinic and patients’ homes. Participants: Fifty patients who had undergone total hip rthroplasty (THA) with trochanteric osteotomy. Intervention: Patients were verbally instructed by a physial therapist to perform partial weight bearing at a 10% body eight (BW) target load (n 33) or at a 50% BW target load n 17). Main Outcome Measures: Mean peak load (%BW) and ercentage of patients and mean percentage of steps below, qual to, and above the target load. Weight bearing was meaured when patients walked with (condition 1) and without condition 2) a physical therapist in the hospital and walked at ome (condition 3). Results: The mean peak load was significantly higher than he target in the 10% BW group for all 3 conditions (condition , 19.2% BW; condition 2, 20.0% BW; condition 3, 26.8% W). In the 50% BW group, the mean peak load was signifiantly lower than the target in conditions 1 (28.1% BW) and 2 32.5% BW). No significant difference in weight bearing was ound when walking with or without a physical therapist change in 10% BW, 0.1% BW; change in 50% BW, 3.17% BW). At home, the mean peak load was significantly arger compared with walking without a physical therapist in he hospital (change in 10% BW, 7.0% BW; change in 50% W, 11.5% BW). Conclusions: Partial weight bearing at a specific target load as not achieved by patients with a THA when given verbal nstructions. Especially when using a low target load and when alking at home with no supervision of a physical therapist,
