BRAKE RESPONSE TIME BEFORE AND AFTER TOTAL KNEE ARTHROPLASTY: Tracking Possible Effects of the Surgery Technique on Motor Performance: Report of Two Cases

摘要

After total knee arthroplasty (TKA) patients often ask when they can resume car driving. This question was the aim of some studies in the past, however no study was found on the possible effects of different surgery techniques on brake response time (BRT). A randomized controlled trial on the effects of two surgery techniques (minimally invasive vs. standard approach) on BRT was designed. In this paper the motor performance of two female patients was compared. Surgery had different effects on the mean BRT of both Patients. The mean BRT of the MIS Patient wasn't increased 7 days after surgery, while the BRT of the Patient undergoing standard surgery was increased by 46.8% at the same time.
