Abstract
A method and device for inserting an implant of synthetic material or healthy bone or cartilage into a bone or cartilage defect of unknown depth. The device includes an inner shaft within a hollow outer shaft. One end of the inner shaft of the device is suitable for inserting into the bone or cartilage defect in order to determine the depth, while the other end of the outer shaft is suitable for holding an implant. The implant is cut to fit the defect once its depth has been determined and then inserted into the defect. A cutting device for cutting the implant is disclosed. Also disclosed is an implant capsule loader for inserting an implant into the delivery device.
