Partial Knees

Partial Knee replacement is becoming more popular because of the faster recovery. This photograph shows the difference between a partial (Unicondylar knee implant ) and a total knee implant which is  larger and covers both condyles of the femur and the entire tibial surface. The knee with the Uni maintains a normal ACL and PCL – Anterior cruciate ligament and Posterior cruciate ligament. This leads to better proprioception in the knee, or position sense.  A study done by Dr. Kozinn showed that more patients who have a a Uni on one side and a total knee on the other preferred the Uni- because it feels more like a normal knee ( sensory nerve feedback).
