Floating joint replacement device with supportive sidewall

摘要

A meniscus replacement device (100) for replacing damaged soft tissue includes a first component (102) comprising a first tissue- interface surface (108) shaped to free-floatingly interface with tissue structure of one of a femur and a tibia in a knee joint having a damaged soft tissue, and comprises a second component (104) comprising a second tissue-interface surface (120) shaped to free- floatingly interface with a second tissue structure of the other of the femur and the tibia in the knee j oint. The second component may include a containment cavity (140) receiving at least a portion of the first component. In another form, the free floating soft joint tissue replacement component and the base component are fixed together. In some aspects, the second tissue-interface surface is shaped to fit contours of a natural tibia plateau. In some aspects, the first tissue- interface surface is shaped to fit contours of a femoral surface.
