Abstract
A unicompartmental meniscal prosthesis having a kidney-bean shape and being suitable for surgical implantation into the lateral compartment of the knee that is defined by the space between a femoral condyle and the respective tibial plateau. The prosthesis has fixation members at the posterior and anterior ends.
Claims20
A meniscal prosthesis implantable in a knee joint, the meniscal prosthesis comprising:
- a body adapted to be implanted in a lateral compartment of the knee joint between a femoral condyle and a tibial plateau and having an articulating surface adapted to articulate with the femoral condyle, a bearing surface adapted to rest adjacent the tibial plateau, and a periphery defined by lateral, medial, anterior, and posterior sides, the body further having a kidney-bean shape and a first fixation member being adapted to engage tibial bone to permanently fix the body to the bone.
A implantable prosthesis, comprising:
- an elliptically shaped body implantable in a lateral compartment of a knee joint between a femoral condyle and a tibial plateau of a tibia, the body having an articulating surface adapted to articulate with the femoral condyle, a bearing surface oppositely disposed from the articulating surface and adapted to rest adjacent the tibial plateau, and at least one fixation member adapted to permanently connect the body to the tibia.
A meniscal prosthesis implantable in a knee joint, the meniscal prosthesis comprising:
- a body adapted to be permanently fixed in a lateral compartment of the knee joint between a femoral condyle and a tibial plateau of a tibia and having an articulating surface adapted to articulate with the femoral condyle, a bearing surface adapted to rest adjacent the tibial plateau, and a periphery defined by lateral, medial, anterior, and posterior sides, the body further having a first fixation member being adapted to engage tibial bone.
