MAKO Partial Knee Replacement (MAKO UKR)
Partial knee replacement is a surgical procedure that replaces one of the 3 compartments in the knee.
A normal knee is made up of three parts,
- medial (inside),
- lateral (outside) and
- the patello-femoral (knee cap) compartments.
When only one part of the knee is diseased, it is potentially possible to replace only that part. This is called a partial knee replacement or uni-compartmental knee replacement (UKR).
The advantage of an UKR over a total knee replacement (TKR) is that the natural movements and feel of the knee is maintained and therefore patients feel that the partially replaced knee is more natural compared to a fully replaced knee.
- recover faster,
- report better satisfaction, and
- return to more physical activities
compared to patients with a traditional TKR.
There are some disadvantages:
- Patients may continue to experience mild symptoms from the un-replaced parts of the knee.
- Patients may require secondary procedures if the un-replaced parts of the knee significantly deteriorate.
- The partial knee replacement may wear out faster than a tradition total knee replacement.
The MAKO UKR is partial knee replacement which is performed using the robotic navigation MAKO platform. [LINK]
A special CT scan is performed of the knee allowing the production of 3D preoperative planning of the procedure prior to surgery.
During the surgery, the surgeon feeds real-time information about the patient’s knee back to the computer system and surgical planning is fine tuned to better balance the knee. The MAKO robotic arm then assists the surgeon to perform bone preparation with precision for the final implantation of the partial knee replacement. Finally the components are secured in placed with bone cement.
