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.
Partial Knee Resurfacing (PKR)
There are three compartments to the knee: the medial (inside) compartment,
the lateral (outside) compartment and the patellofemoral (kneecap) compartment.
Depending on where the 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
Partial Knee Resurfacing (PKR) Triathlon PKR is
a fixed bearing unicompartmental, or unicondylar,
knee that blends the ease and familiarity of a
measured resection system with the control of a gap
balancing system. This bone-preserving approach
eliminates the need to violate the intramedullary
(IM) canal, and provides the potential to return
patients back to their normal activities.1,2
The Triathlon Partial Knee Resurfacing (PKR) System was
designed to make unicompartmental knee resurfacing (UKR) potentially easier and
more straight forward. The patented single radius design, coupled with the
ability to balance the flexion and extension gaps, is intended to produce more
stable, natural knee motion.3,4 The result is an elegant solution, helping to
restore normal physiologic ligament tension and knee kinematics throughout the
range of motion.
Features & Benefits
Two components:
Motion
Patented Single Radius
-
designed to provide ligament stability through the range
of motion.3,4
Ligament Balancing -
designed to restore normal physiological ligament
tension.
Anatomic Shape -
the femoral component features a 7.5 degree bend to match the
natural curve of the femoral condyle.
Simplicity
Easy Size Interchangeability
- bone cuts are the same for
all 6 sizes. This provides intra-operative flexibility
to change sizes without recutting the femur.
Straightforward Gap Balancing
Technique - instruments designed to
provide a simple way to balance flexion and extension
gaps and restore normal ligament tension.
Procedural Efficiency -
fewer instruments, pinless option, and “drill through”
trials, allow surgeons to optimize positioning of the
femoral component prior to peg prep.
Navigation -
designed for use with navigation software.
Confidence
X3 Advanced Bearing
Technology - Triathlon Partial Knee Resurfacing
system utilizes Stryker's proprietary X3 highly crosslinked bearing technology, which has shown a 96%
decrease in wear in laboratory testing compared to
competitive premium bearing surfaces in TKR’s.5
Forgiving Design -
the femoral component can withstand up to +/- 10 degrees
of malalignment without edge loading.
