What is Unicompartmental Knee Replacement?

Unicompartmental knee replacement (UKR) is a surgical procedure that is used to treat arthritis in one compartment of the knee. Unlike a total knee replacement, which replaces the entire knee joint, a UKR only replaces the damaged compartment of the knee.

  • During the procedure, the damaged cartilage and bone are removed from the knee joint and replaced with metal and plastic components.
  • These components are designed to mimic the movement and function of a healthy knee joint.
  • UKR is typically recommended for people who have arthritis in only one compartment of the knee, such as the inner or outer compartment.
  • It is also typically recommended for people who have less severe arthritis, as well as for older adults who may not be candidates for a total knee replacement.

UKR offers a number of potential benefits over a total knee replacement, such as:

  • faster recovery time
  • less pain
  • less blood loss
  • smaller incision
  • improved range of motion
  • less bone removal
  • lower risk of complications

However, it's worth noting that UKR may not be suitable for everyone and it is important to discuss with a medical professional the best option for each specific case.
