  • Preparation for repairing cartilage defects or cartilage/bone defects in human or animal joints
    Patent number: RE43714
    Abstract: Repairs of cartilage defects or of cartilage/bone defects in human or animal joints with the help of devices including a bone part (1), a cartilage layer (2) and a subchondral bone plate (4) or an imitation of such a plate in the transition region between the cartilage layer (2) and the bone part (1). After implantation, the bone part (4) is resorbed and is replaced by reparative tissue only after being essentially totally resorbed. In a critical phase of the healing process, a mechanically inferior cyst is located in the place of the implanted bone part (1). In order to prevent the cartilage layer (2) from sinking into the cyst space during this critical phase of the healing process the device has a top part (11).
