Shoe outsole for decreasing knee adduction moment


The present invention relates to an outsole for decreasing a knee adduction moment that has a front foot portion and a rear foot portion having different inclined angles corresponding to the knee adduction moments generated differently during walking operations in which a user's outsole contacts the ground, that is, standing, grounding and jumping operations, so that the knee adduction moments are decreased in accordance with the characteristics of the walking operations, thus adjusting bow legs or knock-knees, releasing and further preventing the pain of the knee joints, efficiently releasing the impact applied to the knee upon climbing mountains, and maintaining stable posture upon golf swing operation.. .

Posterior stabilized knee prosthesis


A knee joint prosthesis includes a femoral component having an anterior side, a posterior side, a pair of laterally spaced condylar portions, and an intercondylar portion joining the condylar portions and including a recess. A cam surface is located adjacent the intercondylar recess on the anterior side of the femoral component and has a saddle shape that is defined by an at least substantially concave first radius of curvature and a convex third radius of curvature that is perpendicular to the concave first radius of curvature.

Knee joint supporter


A knee joint supporter which can improve the stability of the knee joint, reduce the wearer's fatigue and reduce the load on the patellar tendon includes a first anchor section formed by wrapping one end of a tubular knitted fabric around the wearer's thigh to tighten it with the fabric, a second anchor section formed by wrapping the other end of the fabric around the wearer's lower thigh to tighten it with the fabric, and a substantially u-shaped knitted supporting section joined to the first anchor section, covering the wearer's patella region and thus supporting the wearer's patella. In the circumferential direction of the fabric, the stretch resistance of the two anchor parts are larger than the stretch resistance of a base fabric section.

Tibial component


A tibial knee joint prosthesis for attachment to a suitably prepared tibial bone, providing bearing portions in the lateral and medial compartments. The lateral and medial bearing surfaces of the component are inclined at different angles in the anterior to posterior direction of the knee, so that when mounted to the tibia, the lateral bearing surface of the prosthesis is higher than the medial bearing surface to the posterior side of the knee.

Device for positioning joint line for revision total knee arthroplasty


A device for positioning a knee joint line for revision total knee arthroplasty. In revision total knee arthroplasty, the position of the joint line of an existing femoral element is measured before the existing femoral element is removed from the femur in revision total knee arthroplasty.
Corentec Co., Ltd.


Patient-matched total knee arthroscopy


A gauge assembly includes a distal femur gauge including medial and lateral condyle paddles each having a shape and size corresponding to a pre-operative planned distal resection of a patient's femur, and a tibial cutting block connected to the distal femur gauge. The condyle paddles include features, for example, pin-receiving holes, that permit intra-operative anterior-posterior and/or internal-external adjustment of the position of the distal femur gauge.

Integrated medical shoe device


This invention generally relates to a shoe in which an orthopedic adjustment has been integrated into the construction of the shoe itself. The invention entails adjusting one or more of the soles or other construction features of the shoe itself in order to accommodate a medical condition or treatment regimen.
