Driver reaction times after total knee replacement

Abstract: We measured the driver reaction times of 40 patients before total knee replacement (TKR) and 4, 6, 8 and 10 weeks after operation. The ability to perform an emergency stop was assessed as the time taken to achieve a brake pressure of 100 N after a visual stimulus. There were 18 drivers and 11 non-drivers; the latter had longer reaction times. In drivers, the ability to transfer the right foot from accelerator to brake pedal did not recover to preoperative levels for eight weeks after right TKR and was unchange… Show more

“…A similar correlation was found in these patients between stepping and standing tests and brake response time [22]. Patients with a right TKA had normal brake response times and total brake times 2 to 8 weeks postoperatively [9,28,36,37,42,50,57] and normal brake response times 0 to 3 weeks after a left TKA [36,37,41,50,57]. Data showed that a step test was the best predictor of safety when correlated with total brake time after TKA [28].…”

“…Several previous publications document a return to baseline braking ability after right TKA [6,10,11]. Our study, looking at contemporary TKA, shows a quicker recovery to baseline compared with that of more traditional TKA (Table 3).…”

“…Current literature recommends patient return to driving 4 -8 weeks after total hip surgery [4,5] and anywhere from 10 days to 8 weeks following TKA [6][7][8][9]. Even though our patients seemed to fall within these recommended guidelines, all recorded accidents occurred within 6 months.…”

“…One factor thought to predict driving ability is reaction time, or the time it takes to react to a stimulus and move from the accelerator to the brake. The literature quotes anywhere from 4 -6 weeks to up to 8 months following hip arthroplasty [4,5] and 10 days to 8 weeks for total knee arthroplasty [6][7][8][9]. To our knowledge, there is no literature in regards to total shoulder arthroplasty and when patients can safely return to driving.…”
