Institutional Review Board, Hospital for Special Surgery
September 15, 2014
The safety of study participants is our top priority. The trial is approved and periodically reviewed by an Institutional Review Board (IRB), which includes doctors, administrators, ethicists, and members of the general public. The safety of clinical trials is reviewed by the U.S. Food and Drug Administration.
Before enrolling in a clinical trial, the investigator will explain the purpose of the trial, its expected benefits, any possible risks or side effects, and what your role will be. This is the time to ask questions! If you want to join the trial, you must sign the informed consent documents. You can leave a clinical trial at any time without penalty.

After total knee arthroplasty, patients are eager to resume activities of daily life, such as driving. But in the immediate post-operative period, patients exhibit an unsafe increase in driving reaction time. Most surgeons recommend that patients wait until 6 weeks after surgery to resume driving. But no evidence indicates that a patient may not return to driving sooner than 6 weeks post-TKA. Taking into consideration the eagerness of the TKA patient to resume driving, as well as their safety and that of other drivers, we want to determine at which post-operative week patients may safely return to driving. We are recruiting 180 patients for two 10-minute visits, the first pre-operatively, and the second 4-6 weeks after surgery, where we will test their driving reaction time using a driving simulator machine.
• Right total knee arthroplasty patients between the ages of 40 and 80 scheduled for surgery by Dr. Westrich/Dr. Haas/Dr. Figgie/Dr. Windsor
• Patients who do not have the means to return for at least one follow-up appointment.
• Patients who don’t drive
• Patients who did not drive for more than 3 months prior to surgery
• Patients who mainly drive a car with a manual gear shift
• Patients who brake with their left foot
• Patients who are having revision surgery
• Patients who are having bilateral surgery
• Patients who develop complications that would affect recovery time
