in partial knee
MOTO Lateral is a compartment-specific, fixed-bearing implant that further expands the MOTO Partial Knee System, offering the opportunity to treat osteoarthritis localized on the lateral femoral and tibial condyles. MOTO Lateral and MOTO Medial provide the surgeon with a comprehensive range of options to resurface only the affected portion of the patient’s knee.
MOTO Lateral was designed with the aim of optimizing the anatomical fit and compartment-specific coverage for the broadest range of patient anatomies. It features a patient-specific gap balance and alignment technique with minimal and precise bone resections, without ligament releases. The implant design and instrumentation work together so that intraoperative decision-making and flexibility are optimized for each patient.
The fixed-bearing, round-on-flat design in partial knee replacement has demonstrated the potential to provide excellent midterm and long-term results, as reported in clinical studies and registry data [1-5]; however, there is still potential for improvement in terms of anatomic fit, size range, intraoperative feel and technique. Both MOTO Medial and MOTO Lateral Partial Knees have been developed in alignment with this proven philosophy, but feature an improved implant and instrument design, as well as flexibility of the system, taking the potential of partial knee arthroplasty to the next level.
The MOTO System was designed with clear goals:
To achieve improvements to patient outcomes, surgeons can rely on the following unique and superior MOTO System features:
Anatomic design, specific for lateral compartment
7 sizes for Right/Left Lateral component
Material: Cobalt-Chrome (Co-Cr-Mo ISO 5832-4) or Cobalt-Chrome (Co-Cr-Mo ISO 5832-4) + SensiTiN coating
Anatomic, specific for lateral compartment
8 sizes Right Lateral / Left Lateral
Material: Titanium (Ti-6Al-4V ISO 5832-3)
Anatomic, specific for lateral compartment
8 sizes that couple with right/left tibial trays
7 levels of thickness: 7*, 8, 9, 10, 11, 12 and 14 mm
Material: Machined Ultra High Molecular Weight
Polyethylene (UHMWPE - ISO 5832-2 Type 1) or E-CROSS (Vitamin E Highly Crosslinked UHMWPE)
*available only as E-CROSS poly.
Extensive anthropometric research was performed on selected cases from our internal database containing more than 45.000 CT and MRI scans of knees from all countries to validate the MOTO implant design.
Uncompromised fit, coverage and positioning
The MOTO “Balanced & Aligned Resection Philosophy” enables independent balancing of the flexion and extension gaps in 1mm increments.
Balance without complexity, maximize individualized outcome
MOTO offers you MORE to deliver the best outcomes for your patients.
