摘要

Although the results of medial unicompartmental knee arthroplasty (UKA) are extremely positive in most of the cases, several technical aspects are still discussed. Cementation or not is one of them and no clear advantage of one option over the other has emerged; similarly mobile and fixed designs have similar outcomes. Metal back implants although more common than all-poly implants do not have clearly superior outcomes. Similarly technological innovations are leading the research toward more accurate reproduction of unique patients’ anatomy and function with the surgical procedures. Robotics aim at reproducing the pre-arthritic individual joint line and lower limb alignment while custom implants would reproduce the anatomy of the articular surfaces. All these aspects will be discussed in the following article.
