Abstract

Following a right-sided total knee arthroplasty (TKA), standard clinical recommendations for patients is to refrain from driving for 6 weeks. Clinical assessments of recovery include mobility tests but do not specifically assess fitness to drive. As a first step in assessment of driver readiness, this study aimed to compare vehicle entry behaviors and mobility assessments between TKA patients and healthy controls. 18 participants (9 TKA participants) completed three in-laboratory visits where they completed mobility tests and entered a full-cab car. Videos of vehicle entry were reviewed and annotated for time--timed vehicle entry (TVE)--and to categorize entry mode. TVE was significantly slower for TKA participants before surgery and 3 weeks after the procedure (p < 0.05) but not 6 weeks after (p < 0.05). TVE was positively correlated with timed up and go (TUG, r = 0.65, p < 0.05) and negatively correlated with right knee range of motion (ROM, r = -0.5, p < 0.05). Range of motion was not significantly different across entry modes between TKA participants and controls. This study was not conclusive to the utility of TVE to replace ROM and TUG for driver readiness; however, this work demonstrated the use of a real-world task that is related to driving for providing patient recovery and behavioral information.
