There are three compartments to the knee: the medial (inside) compartment, the lateral (outside) compartment, and the patellofemoral (kneecap) compartment. Depending on where arthritis affects your knee, partial knee resurfacing may be an option for you. PKR is a growing procedure. There are approximately 70,000 partial knee resurfacing procedures done in the U.S. each year.2
Partial knee resurfacing (PKR) is a surgical
procedure for relieving arthritis in one
compartment of the knee. With PKR, only the
damaged surface of the knee joint is replaced,
helping to minimize trauma to healthy bone and
tissue. The surgeon removes only damaged bone
in the affected knee and fits the implant to that
bone. Because the PKR artificial joints are smaller
than total knee implants, the surgical incision
may be smaller as well.
Since most of the knee joint is unaffected and the basic knee structure remains intact, post-operative pain may be reduced and the recovery period may be shorter than total knee replacement.3
Triathlon® PKR was developed with patient needs in mind. The implant is anatomically shaped and helps enable surgeons to use the latest minimally invasive surgical techniques. With this procedure, only the affected compartment of the arthritic femur and the tibia are resurfaced with artificial implants.
