Minimally invasive unicompartmental knee arthroplasty

Expert's Opinion • KNEE - ARTHROPLASTY


The exact indication for a unicompartmental knee arthroplasty (UKA) remains debated. Minimally invasive techniques have been developed to decrease the surgical trauma related to the prosthesis implantation, and this technique is well fitted to UKA. However, there are concerns about loss of accuracy with minimally invasive techniques. Furthermore, rapid recovery techniques have been developed in order to reduce the length of hospital stay. Again, UKA is well fitted to these new developments of postoperative care. We combine routinely a minimal invasive operative technique with navigation assistance to ensure proper positioning of the implants as well as an optimal ligamentous balance. Instruments have been adapted for use with a typical 6-cm skin incision with little change from the conventional navigated operating technique. A multimodal pain treatment is implemented immediately after the implantation, with special attention to a routine saphenous nerve blockade. Patients are instructed to stand up on the day of surgery with full weight bearing and to mobilize the knee joint without restriction. They may be discharged at least on the day following surgery, and the most favorable patients may be operated in our day-case surgery unit. These conclusions should be confirmed on a larger scale.
