Abstract (en)
[origin: WO9921497A1] Endochondral or osteochondral defects, especially joint cartilage defects are repaired by making cylindrical holes (21) in the area of the defect and implanting columns of tissue (2) with a vital cartilage layer (2') on one front surface, said columns of tissue (2) being taken for example from a less strained joint site. The chances of success of this type of reparation are improved by increased precision. To this end, a guiding instrument for precisely guiding cutting or boring instruments is used for making the holes (21). Said guiding instrument can be positioned and fixed in the area of the defect. Consequently it is possible to achieve a high degree of precision in terms of the parallelity and the position of the holes (21). It is also possible to reconstruct an original cartilage surface very accurately by determining an original cartilage surface and then matching the axial length and the angle between the cartilage surface and the column axis of the column of tissue (2) to be implanted to this original surface. Gaps between the implanted tissue columns (2) and on the edges of the defect in the reconstructed cartilage surface are also filled using another implant from a layer of cartilage (50) grown in vitro.
