The economic impact of minimally invasive total knee arthroplasty

The goals of minimally invasive surgery (MIS) total knee arthroplasty (TKA) are to minimize surgical trauma, minimize blood loss, and maximize the effect of analgesia. Assuming these surgical procedures are successful and rigid fixation is achieved, the result, in theory, should be shorter hospital stays and successful, early, aggressive rehabilitation at reduced cost relative to standard TKA surgical techniques. In this article, I address the economic benefits of applying MIS TKA surgical techniques compared with standard TKA surgical techniques.
