Conventional treatment methods and their prospects of success.

Conventional Treatment Methods

chondrotissue® unifies the advantages of conventional therapies. It guarantees patients the most efficent cartilage regeneration in only one intervention. chondrotissue® uses the regeneration potential of the body’s own stem cells and offers an ideal environment for the formation of new cartilageneous tissue inside the joint. The treatment with chondrotissue® does not affect the condition of other joint areas, as it happens in mosaicplasty and ACI. Read more about chondrotissue®.

Microfracture / Pridie drilling / Abrasion Arthroplasty

Drilling into/milling/roughening the bone lying under the cartilage to allow stem cells to grow into the defect with the intention of stimulating cartilage formation. Repair cartilage is usually formed but, though it covers the defect, it cannot function like articular cartilage. The repair tissue is generally of poor quality and has a low mechanical load capacity. It loses its consistency and resistance at an early stage so that the patient often needs further treatment or surgery.

Mosaicplasty

Removal of cartilage cylinders from a location in the joint that is subject to less strain in order to transplant them into the defect. Using this method, coverage of the defect is limited and new defects are created at the donor site.

ACI (Autologous Chondrocyte Implantation)

For many years this method was regarded as particularly promising for treating moderately severe cartilage degeneration. In this procedure, a piece of cartilage is taken from the patient (biopsy). The autologous cells are multiplied in the laboratory. After a few weeks, a suspension (fluid) containing cartilage cells is available, which is then injected into the defect in a transplant process. The cartilage defect is covered up beforehand with a periosteal patch previously taken from the shin bone.

Despite good clinical results, the ACI method also has a few drawbacks. An additional operation is required to obtain the periosteal patch, involving more pain and risk for the patient. Then the periosteal patch must be fixed by suturing to the healthy cartilage. Other disadvantages are poor mechanical stability and the problem that cartilage cells can “leak out” under the periosteal patch on the slightest exertion.
