Improvement in Driving Reaction Time After Total Hip Arthroplasty

Abstract

Decisions made regarding resumption of driving after total hip arthroplasty may be determined by a combination of factors including driving reaction time and when postsurgical precautions need no longer be adhered to. Ninety patients, ranging in age from 34 to 85 years old were recruited after total hip arthroplasty to measure driving reaction time preoperatively and from 1 to 52 weeks postoperatively. Driving reaction time worsened 1 week postoperatively for patients who had a right hip arthroplasty. The driving reaction time then improved up to 1 year postoperatively. Patients who had a left arthroplasty improved from 1 week postoperative. In general, patients reach their preoperative driving reaction time 4 to 6 weeks postoperatively and continue to improve.
