Abstract: A method and implant to treat anterior cruciate ligament (ACL) injuries are disclosed. The method involves advancing the insertion of the patellar ligament to the proximal tibia. The implant includes a spacer (30) which is inserted between the patellar ligament and the tibia and fixed to the tibia. The spacer decreases the angle between the patellar ligament and the tibia plateau and consequently modifies the internal joint force, restoring stability to the joint even if the ACL is ruptured. The method and implants are applicable to both human and canine patients.

Abstract: A modular elbow prosthesis is disclosed, as well as a surgical approach and implantation technique, for using the prosthesis. The system is the first and only to allow for a, Biomechanically Anatomical, Nonconstrained, Compartmental (BANC) Elbow Arthroplasty. The modularity of the system allows it to be implanted as an unicompartmental or partial elbow replacement or a total elbow replacement. The modular elbow prosthesis for partial elbow replacement includes a cylindrical medial humeral component, a polyethylene ring thereon, and a semicircular medial ulnar component which mates with the polyethylene ring. Additionally, for total elbow replacement, the modular elbow prosthesis also includes a circular lateral humeral component, a polyethylene ring thereon, a semicircular lateral ulnar component, and a radial component. Implantation of the prosthesis is through a minimally invasive medial surgical approach with the aid of precision biomechanical guides.
