Autologous Chondrozytentransplantation of the upper ankle What are the causes of cartilage damage, there is at the upper ankle?The majority of cartilage damage at the upper ankle joint result, unlike at the other joints of the body from accident injuries. When Umknicken with the ankle to the outside, there is an excessive shear stress on the cartilage of the outer anchor leg and massive pressure on the inner anklebone share with bruising of the cartilage under the underlying bone, the damage in the joints can cause. Moreover, grinding bone spur on the anterior edge of tibia cartilage damage in ankle führen.Eine further cause of damage to the cartilage Sprungelenk are the 'avaskulären osteonecrosis': here dies of bone from an unknown cause, so that the higher cartilage, ultimately resulting in the bone defect collapses. |  How is the cartilage transplant performed? |
When is the autologous cartilage cell transplantation a promising method?
For some cases is consistent with the autologous chondrocyte implantation is a promising method in the laboratory bred cartilage cells transplanted from. Since the implanted material has similar biomechanical properties as the natural cartilage has, it is not absorbed by the body sees as foreign. The living chondrocytes are in a position to return for the establishment of a functioning cartilage layer them. As a rule, already after a few weeks, new cartilage tissue formed. To this tissue to be preserved even in the long term, it is necessary accompanying injuries and abnormal by Achsfehlstellungen be included.
How can the cartilage cells, or minimally invasive arthroscopic ankle to be introduced?
Who is for an autologous cartilage transplantation for?
The possibility of a cartilage transplantation (transplantation of cartilage cells) is limited. Before a therapeutic decision must be clarified whether a low-invasive procedure with einzeitigem approach is preferable.
With an autologous cartilage cell transplantation in a first meeting cartilage cells collected and then cultured in a special laboratory for a period of 4-8 weeks re-implanted.
Ideally suited for the method:
- Patients under 40 years
- national standing of the ankle cartilage damage
- Damage to the cartilage damage size of 1.5 cm2
It is important to continue the consideration of multiple mobilities in the ankle (ankle instabilities) or Achsfehlstellungen the leg. These must be treated simultaneously to Einheilen of cartilage cells ever to be able to achieve.
Which procedure to Knorpelzelltansplantation we use?
In recent years we have far-reaching achievements in the field of cartilage treatment achieved. The 3D Company ARTHROcell codon, the free transplantation of cartilage cells under arthroscopic interventions possible.
The largest experience exists on the knee joint. The transfer of the gentle methods of the upper ankle joint was therefore the logical consequence. We transplanted today removed from arthroscopic cartilage cells without the use of foreign materials called matrix components.
What alternatives are there for autologous cartilage cell transplant?
The potential cartilage damage with knochenmarkstimmulierenden or methods such as Knochenanbohrung Mikrofrakturierung (Microfracturing) to deal with are limited. In the upper ankle joint, these methods for damage under a qcm and centered on anklebone able to use. The faserknorpelige replacement tissues, however, has a low durability against mechanical stress. It uses a special instrument to the bone below the damaged cartilage anzufrischen. This is done by taking in one of certain depth. When drilling creates heat that may damage the bone and the formation of cartilage replacement should obstruct.
