Partial Knee Resurfacing
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.
Total Knee Replacement
Total Knee Replacement (TKR) may be necessary if more than one compartment of your knee is arthritic. In TKR, your surgeon will replace all 3 compartments of your knee using total knee components.
Risks Associated with PKR/TKR
As with any surgery, there is a risk of complications. Blood clots are the most common complication after surgery. Your doctor may prescribe one or more measures to help prevent blood clots from forming in your leg veins, such as special support hose and blood thinners. You may also receive antibiotics to help prevent infection. Your doctor can provide you with more information about other potential risks.
Risk factors relating to your anatomy, weight, prior joint surgeries and your personal health should also be addressed with your doctor.
