Postoperative Hip Precautions After Total Hip Arthroplasty Via the Posterior Approach: A Prospective Randomized Trial
Postoperative Hip Precautions After Total Hip Arthroplasty Via the Posterior Approach: A Prospective Randomized Trial
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.
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.
Inclusion Criteria:
