The MOTO™ Lateral Partial Knee System is designed for cemented use in partial knee arthroplasty, if there is evidence of sufficient sound bone to seat and support the components. Partial replacement of the articulating surfaces of the knee is indicated when only one side of the joint is affected due to the compartmental primary degenerative or posttraumatic degenerative disease, previous tibial condyle or plateau fractures, deformity or revision of previous arthroplasty.
