Custom Fit Total Knee Replacement
Custom Fit Knee™: With Custom Fit Knee™ replacement, the surgeon matches the size and placement of the implant to each particular patient. Instrumentation and implants are pre-planned, based on the patient’s normal (non-diseased) knee anatomy. This means that the surgery can be done accurately and quickly, with less intra-operative decision making required from the surgeon. In addition, less bone is cut and all ligaments are spared, preserving the feel of a more “natural” feeling knee based on the patient’s normal knee function.
While all surgical procedures involve risk, Custom Fit Knee™ replacement was designed to minimize the risks often seen with traditional and computer-assisted techniques. With the custom fit approach, patients spend less time under anesthesia, have no additive risk of cardio-pulmonary complications (caused in traditional surgery by the placement of an intramedullary guide rod) and have up to 40% less bone removed from the femur (thigh bone). They have also reported less post-operative pain.
With the custom-fit knee, patients are reporting significantly less pain both after surgery and throughout their recovery. They also have a greater increase in their flexion and range of motion. This translates into an earlier return to daily living activities and/or employment. Most patients are off of a cane or walker by as early as 2 to 3 weeks and are able to return to activities such as driving, gardening and golfing by as early as 6 weeks.
Potential Benefits of PKR
The bearing surface is defined as the two parts of the knee implant that glide together throughout motion. Triathlon® PKR utilizes Stryker’s advanced bearing technology, called X3®, which has demonstrated up to 96% decrease in wear in laboratory testing compared to competitive premium bearing surfaces in TKRs.4 Triathlon® PKR is the only unicompartmental knee with this technology.
Because the PKR artificial joints are smaller than total knee implants, the surgical incision may be smaller. A smaller incision may lead to a smaller scar. Other potential benefits to PKR include a quicker operation and a shorter hospital stay compared to a total knee replacement.3 Rehabilitation may also be more progressive.3 Because less bone is removed and there is less trauma to soft tissue during surgery, your knee may feel more natural than with a total knee replacement.3
Not all patients are candidates for Partial Knee Resurfacing. Depending on your condition, a total knee replacement may be recommended by your doctor.
