Unicompartmental or total knee arthroplasty?

Abstract

The interest in minimally invasive arthroplasty procedures has increased in the recent years. Application of this technique via a smaller incision or multiple smaller incisions, and some advantages such as less pain, quicker recovery, and shorter hospital stay may appeal to our senses. However, there is considerable data that, in the short-term, minimally invasive arthroplasty does not overcome many serious early and late complications that occur with standard arthroplasty and that it is associated with worsening problems. Therefore, until we have convincing scientific data in terms of greater safety and efficacy with this technique, it should not be used for marketing.
