Unicompartmental or partial knee arthroplasty (UKA) is indicated if degenerative changes are limited to one compartment of the knee. The surgical procedure replaces only the affected compartment, differentiating a medial and lateral unicompartmental knee replacement and the patellofemoral knee replacement. The medial unicompartmental knee replacement is the most common of these.

The benefits of a UKA include less blood loss, quicker recovery, shorter hospital stay, increased range of motion (ROM), higher postoperative activity levels, and earlier return to work. UKAs have decreased infection rates and lower perioperative complication rates.

This is once again one of my specialities and I have operated on many a patients from 45 to 85 and boast of excellent results in most patients.
