Partial & Total Knee Replacement

Partial Knee Replacement

Surgeons at Cascade Orthopaedics are skilled in partial knee replacement which offers several advantages over total knee replacement for eligible patients. The Oxford® Unicondylar Knee Replacement has been in use in Europe for over 25 years, and has been available in the U.S. since October of 2004. Long-term experience has proven excellent survival and function, and in most cases, no need for a total knee even after 25 years. The primary advantages of the Oxford® Partial Knee include 75% less bone removal, less postoperative pain and more natural motion than a total knee replacement. In addition, the Oxford® Knee may be implanted utilizing a minimally invasive procedure that is designed to allow for a more rapid recovery. One of every four osteoarthritic knees may potentially be treated conservatively with the Oxford® Partial Knee.

Total Knee Replacement

Cascade Orthopaedics is the first in the Pacific Northwest to offer a new technology which revolutionizes the way surgeons perform total knee replacement.

First there were generic one-size-fits-all knees. Then companies developed artificial knees targeted specifically at the unique needs of women. Now, the technology is available to have precise bone cuts and implant sizing custom-fit just for your particular and unique anatomy, whether you are a man or a woman. The difference is analogous to a custom-tailored suit or dress versus one off the rack.

Using the Custom Fit™ technology, orthopedic surgeons can for the first time precisely match the size and placement of the implant to the patient's unique and normal (non-arthritic) knee anatomy.

This new "custom fit" approach enables surgeons to preserve more bone, allowing for better implant fit and alignment. Custom Fit™ physicians and patients have reported a quicker and less painful recovery, increased range of motion, a more "natural" feeling knee, and greater ease in performing normal living activities such as golfing, biking and gardening.

This new technology allows us to be able to provide a total knee replacement that is custom fit to each individual patient, very precisely and consistently. The custom fit total knee replacement is achieved in a few steps, before and during surgery. Prior to surgery, an MRI is performed to take very precise measurements of the patient's arthritic knee. Second, proprietary computer software creates a 3-D image of that knee, and then virtually corrects the deformity to return the knee to its pre-arthritic state. Third, a computerized 3-D image of the implant to be used in the patient's surgery is then Shape-Matched™ to the anatomically correct virtual knee model. This helps determine the correct implant size and placement, based on the patient's own normal (non-arthritic) knee anatomy. Last, using all of this information, special cutting guides are created for the surgeon to use during the procedure. These patient-specific cutting guides, which are accurate to within a few millimeters, indicate to the surgeon exactly where to make bone cuts so that the knee replacement is customized for the individual patient.
