Minimally Invasive Total Knee Arthroplasty with an Optimized Subvastus Approach

A modified subvastus approach to the knee that markedly facilitates minimally invasive (MIS) knee replacement surgery is described. Using a readily available set of retractors the surgeon can perform the surgery without guesswork and without free-hand cuts, thereby maintaining surgical accuracy and patient safety. This MIS-optimized subvastus approach is a reliable, reproducible and efficient means of performing MIS total knee arthroplasty. The technique is amenable to step-wise surgeon learning and can be applied to a wide range of patients who require total knee arthroplasty.
