Details and patient eligibility

About

The purpose of this study is to determine if hip precautions, which are instructions that limit functional use of a hip replacement after surgery, affect the rate of dislocation in the first six weeks after primary total hip replacement surgery. The impact of hip precautions on a patient's return to activities of daily living and overall patient satisfaction will also be investigated. The overall cost effectiveness of hip precautions will be determined.

Full description

This study examines the necessity of postoperative hip precautions in patients after primary total hip arthroplasty via the posterior approach. Precautions are instructions that limit the functional use of the hip and are given for the first six weeks after surgery, with the goal of preventing an instability event resulting in dislocation. The hip precautions that will be investigated in this study are: no hip flexion past 90º, no crossing the legs, and no twisting at the waist.
