“The KineMatch device has offered a remarkable benefit and return to function for a number of my patients with intractable patello-femoral disease who were otherwise facing the prospect of patellectomy or TKR.”

KineMatch™ Patello-Femoral Replacement*

Designed specifically for the small but challenging group of patients with isolated, end-stage patello-femoral disease, the KineMatch PFR offers a uniquely conservative and effective resurfacing solution. Because the device is custom-fit to the patient’s anatomy using CT data, no resection of femoral bone is required, thus preserving bone stock for the future. A standard dome patella implant is used in conjunction with the femoral component.

And because the goal is not only to reduce pain but also to improve function, the KineMatch PFR is designed to restore knee kinematics by rebuilding the patellar groove for improved patellar tracking and by restoring the A-P position of the patella for proper quadriceps function.

The device is implanted in a simple surgical procedure with minimal joint disruption. A drill template matching the implant in both femoral fit and perimeter shape is provided for each case. The drill template margin is marked and the cartilage is removed from the bone in the area under the femoral component. Three peg holes are drilled in the anterior femur using the template. The CoCr femoral and UHMWPe patella implants are fixed via their pegs using bone cement.

Femoral components thickness is kept to a minimum in order to replicate normal cartilage thickness and provide for normal joint kinematics

Benefits of KineMatch™ Patello-Femoral Replacement

• Created to address intractable patello-femoral disease when other treatment options have failed.
• Designed to approximate normal kinematics by re-establishing trochlear groove alignment and depth while providing an anatomic sulcus to facilitate proper patella tracking
• Avoids femoral bone resection by utilizing CT modeling technology to achieve individual custom fit to the patient’s distal anterior femoral anatomy.
• Custom fit minimizes problems of soft tissue impingement often seen with “off-the-shelf” patello-femoral implant designs.
• As compared to total knee replacement rehabilitation time is significantly decreased.
• As compared to total knee replacement post-operative knee function is better.

Generally operative time is significantly less than total knee surgery.
