Is a minimally invasive approach superior to a conventional approach for total knee arthroplasty? Early outcome and 2- to 4-year follow-up

The early results and the wide indication encourage us to apply the MIS approach instead of the conventional technique. The limitation of this study was the small number of cases in the retrospective point of view. If the number were larger, perhaps other significant differences could be detected. Further investigations on a larger scale are required to solve this problem.
