in partial knee
MOTO Patello-Femoral Joint (PFJ) is a compartment-specific implant conceived to restore a painless patellar movement throughout the whole articular range of motion when the osteoarthritis is localized in the femoral trochlea region. Together with MOTO Medial and MOTO Lateral, MOTO PFJ is part of Medacta’s MOTO Partial Knee System, which provides for surgeons a complete portfolio to manage any type of unicompartmental knee arthroplasty.
MOTO PFJ features a completely guided surgical procedure that avoids the need for any free-hand step and preserves the femoral intramedullary canal. These unique features, together with an optimized implant design, would provide the surgeon a reliable and reproducible system for treating the patellofemoral joint osteoarthritis as well.
MOTO PFJ features an onlay anterior design that immediately captures the patella during the knee extension, preventing patellar subluxation and instability. Distally, the implant has an inlay design to provide the smoothest transition from mid-flexion to complete flexion, thereby decreasing the risk of overstuffing the patella and limiting the load on the PFJ component in complete flexion, where patellar load stress is usually the most elevated.
A dedicated resurfacing patella component, thin and fully congruent with the PFJ trochlea, completes the MOTO PFJ system to further reduce trochlear anterior pressure and compartment overstuffing.
Each component of the MOTO Partial Knee System was designed with the following clear goals:
To achieve improvements in patient outcomes, surgeons can rely on the following unique and superior MOTO System features:
Anatomic side-specific design
6 sizes for Right side paired with 6 sizes for Left side
Material: Cobalt-Chrome (Co-Cr-Mo ISO 5832-4)
Circular symmetric design
6 sizes with increasing diameters
2 groups of dome thickness: 7.5mm for size 1, 2, 3; 8.5mm for size 4, 5, 6.
Material: UHMWPE (ISO5834-2) or vitamin E highly-crosslinked UHMWPE (E-CROSS)
Extensive anthropometric research was performed on selected cases from our internal database containing now more than 100,000 CT and MRI scans of knees from all countries to validate the MOTO PFJ implant design.
Minimally invasive and reproducible surgical technique, where all the steps are well-guided by the intuitive nature of the instruments.
