Total knee arthroplasty (TKA) dramatically decreases pain and improves mobility and quality of life. However, little has been reported on its effect on driving ability in the early postoperative period. This prospective study was conducted to compare preoperative and postoperative brake response times (BRTs) in patients undergoing TKA for osteoarthritis. The results showed that patients returned to preoperative BRT as early as 3 weeks after surgery, and at 9 weeks after surgery, BRTs were significantly improved over baseline. Based on BRT analysis patients undergoing TKA may be allowed to return to driving 6 weeks after surgery.
全膝关节置换术（TKA）能显著减轻疼痛，改善活动能力和生活质量。然而，关于其术后早期对驾驶能力影响的报道却很少。本前瞻性研究旨在比较骨关节炎患者行TKA术前和术后的制动反应时间（BRT）。结果显示，患者在术后3周就恢复到了术前的BRT水平，术后9周时，BRT较基线水平有显著改善。基于BRT分析，行TKA的患者术后6周可允许恢复驾驶。
