Feel the free-glide difference with the new OAK Orthotic Knee Joint from Fillauer. The OAK (Osteo-Arthritis Knee) polycentric orthotic knee joint has been engineered to provide motion that better approximates normal physiologic knee movement for use in a custom Osteoarthritic Knee Orthosis. Unlike simple pivot knee joints, the polycentric action of the OAK provides inherent stability at full extension and easy gliding during swing phase. This allows the patient to feel the “glide flex” stability during the first 5° of flexion.

The laterally mounted OAK joint also incorporates proximal and distal mounting plates with an adjustable range of 6° of genu varum to 30° of genu valgum. This allows the orthotist to fine-tune the amount of medial compartment unloading, to help relieve pain in the knee joint.

OAK features a full range of knee flexion from 12°-150° with a 15° extension stop and 90° flexion stop. The Scandinavian inspired OAK provides function in a thin, cosmetic, and streamlined package and is constructed of special high strength aluminum and stainless steel. You will feel the difference.
