Abstract: A method and system provide and use a patellar implant. The patellar implant includes a superior portion, an inferior portion opposite to the superior portion, and an anterior portion. The superior portion being configured to reside below a patellar tendon and to elevate and/or tilt the patellar tendon. The inferior portion is configured to be seated in proximity to a tibia. The anterior portion is between the superior portion and the inferior portion. The anterior portion is placed in proximity to a patella. In one aspect, the method includes inserting the implant beneath the patellar tendon and between the patella and a position at which the patellar tendon is affixed to the tibia. In this aspect, the method also includes affixing the implant.

Abstract: An orthopedic implant with an inferior portion having a tibia contact surface configured to extend over a tibia; a superior portion opposite to the inferior portion having a tendon contact surface configured to change a position of a patellar tendon by lifting or tilting the patellar tendon when the curved surface of the first portion is engaged with the tibia; and a fixation mechanism adapted to attach the orthopedic implant to the tibia, the orthopedic implant being further configured to change shape from a first configuration to a second configuration in response to a load applied between the tendon contact surface and the tibia contact surface. The invention also addresses corresponding methods.
