Abstract:
PURPOSE: To investigate the effectiveness of minimally invasive total knee arthroplasty using the mini-midvastus approach through analyzing the short-term clinical outcomes. MATERIALS AND METHODS: Seventy-seven consecutive total knee arthroplasties were performed with the mini-midvastus surgical technique from August 2005 to February 2006 and were followed for more than 1 year after the procedure. All operations were performed with the Nexgen LPS-flex total knee system using a MIS quad-sparing instrument. The evaluation included preoperative and postoperative clinical data, surgical and radiological outcomes. RESULTS: The length of skin incision was average 8.4+/-0.6 cm and the operation time was average 95.5+/-15.7 minutes. The blood loss was average 727.5+/-315.5 cc. The tibial component alignment angles averaged 0.2+/-1.3degrees varus and the tibiofemoral angles averaged 5.8+/-1.8degrees. The mean ROM and the mean HSS score was 117+/-10degrees and 120+/-11degrees, 88.9+/-7.1 and 96.2+/-4.5 at eight weeks and one year after surgery respectively. CONCLUSION: If proper surgical procedures are performed using the appropriate surgical instruments, minimally invasive total knee arthroplasty with the assistance of the mini-midvastus approach, can result in good clinical outcomes and alignment of the implants.
