Bi-compartmental Knee Arthroplasty

What is Uni-Compartmental or Partial Knee Replacement?

 
 

The knee joint is a cluster of three small compartments, namely the Outer (1), Inner (2) and the Knee-Cap (3) compartment. Interestingly knee osteoarthritis (OA) has been described as highly segmental, in other words wear and tear of the knee has a strong tendency to restrict itself to a particular compartment, most commonly the inner one.

Unicompartmental Knee Replacement is a surgical procedure done to replace only the worn-out inner compartment of the knee. Unlike total knee replacement where the entire joint is replaced, in Uni-compartmental knee Replacement at least 70% of the knee joint is preserved.
