Explanatory comparative study of conventional Total Knee Arthroplasty versus Robotic assisted Bi-UniCompartmental Knee Arthroplasty


Osteoarthritis (OA) is the most common form of joint disease. It causes pain and stiffness and affects at least 8 million people in the UK imposing a considerable economic and personal burden. The knee is one of the most common sites affected by OA. Knee Replacement, or Arthroplasty, is the current surgical treatment of choice for end stage OA of the knee.

This explanatory randomised controlled trial will compare a novel robotic assisted surgical technique (Bi-Unicompartmental Knee Arthroplasty) against a standard surgical technique (Total Knee Arthroplasty) in patients with osteoarthritis of both the medial and lateral compartments of the knee.
