The routine use of posterior hip dislocation precautions is typically utilized postoperatively following total hip arthroplasty via a posterior surgical approach. This has included use of an abduction pillow and limiting adduction, internal rotation and flexion more than 90 degrees for a minimum of 6 weeks postoperatively. This may slow the course of rehabilitation, increase the length of hospital stay and the total cost of the procedure, and add additional anxiety to the patient. We conducted this study to see if posterior hip precautions are necessary after total hip arthroplasty via a posterior approach when the hip meets certain intraoperative criteria for stability. All patients in our institute undergo routine hip stability testing during primary total hip arthroplasty via a posterior approach. Before October 2010, all of our primary total hip arthroplasty patients were placed on routine hip precautions. We stopped hip precautions in October 2010 for all the patients who were noted to meet hip stability criteria intraoperatively. We prospectively compared the consecutive patients who underwent this procedure without hip precautions with a retrospective control group of patients who had hip precautions.Introduction:
