Advantages of the ADVANCE® Unicompartmental Knee

For patients considering partial knee replacement surgery, Wright's ADVANCE® Unicompartmental Knee System (or Uni-Knee) offers a unique design that matches the anatomical shape of the normal knee. Using the minimally-invasive surgical technique, the surgery can be performed through a 3" to 4" incision (as opposed to an 8" to 12" scar left by total knee replacement procedures).

• Uni-Knee
  3" to 5" median parapatellar incision
  
• Total Knee
  8" to 11" median parapatellar incision

The Uni-Knee replaces designs that required the surgeon to reshape the bone to fit the implant, which resulted in more bone removal. By providing a more normal shape, the Uni-Knee offers more normal motion and may lead to longer implant life, delaying or preventing the need for total knee replacement.
