Short Term Result of Minimally Invasive Total Knee Arthroplasty with Mini-Midvastus Approach

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. 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.
