Partial Knee Replacement
Until recently, a total knee replacement was the operation provided for painful knee arthritis. This operation replaced all mobile surfaces of the native knee with artificial, smooth articulating surfaces – whether they needed it or not. Now, the gold standard is to KEEP THE PARTS OF YOUR KNEE THAT ARE NORMAL and only replace those parts with damaged cartilage. This results in much less surgical trauma, keeping the ligaments and bone that’s normal, shorter hospital stays and easier rehabilitation.
Unicompartmental (Uni) Knee Replacement
Medial (Inner) or Lateral (Outer) Unicompartmental Replacement (Uni Knee) is highly successful with a 10-year survival rate of greater than 95% in some studies and a 20-year survival rate of 92%.
This is comparable or better than a TOTAL knee replacement. It is performed through a tissue-sparing small incision and typically requires only an overnight stay in the hospital.
Patellofemoral Knee Replacement
Patellofemoral Knee Replacement works well in patients with arthritis isolated to the back side of the kneecap and the groove on the end of the thigh bone where it glides.
This, too, has excellent outcomes in a select group of patients. It has been proven to restore function and decrease pain in several long-term studies. It is performed through a tissue-sparing small incision and typically requires only an overnight stay in the hospital.
