Objective: To discuss the preliminary clinical results of total knee replacement with minimally invasive surgery assisted by computer navigation. Methods: 9 patients (10 knees) were operated with navigation assisted total knee replacement through minimally invasive midvastus approach and the incision length, postoperative drainage, operation time,VAS scores, and image restoration were observed. Results: The average incision length of nine patients were(10.7 ± 2.1)cm;the operation time were(100.4 ± 10.3)min; the postoperative drainage in first 24 hours were (200.7 ± 101.9) ml; VAS Scores were 5.2. Conclusion: Computer navigation assisted minimally invasive total knee replacement promises smaller incision, no femoral medullar disturbance, reduced blood loss, quick recovery of lower extremity function,right component position as well as improvement of the overall post-operatively alignment with high accuracy and repeatability.
