For the bone cartilage damage are now several therapeutic approaches are available.
- Drilling of the stove without OD through the cartilage to go, so to speak from the back (retrograde drilling)
- Reconstitution of the bone under the cartilage damage from the back (retrograde Spongiosaplastik)
- Drilling of the OD stove by the cartilage (antegrades after drilling pridie)
- Stabilization of the fragment or stove Osteochondrosis dissecans
- Mikrofrakturierung
- Osteochondrale transplantation in the OD Herd
- Cartilage transplantation (autologous cartilage transplantation)
At an advanced stage of Osteochchondrosis dissecans (III-V with a partial solution to the bone stove to cyst formation) are the usual procedures with drilling of the bone and Mikrofrakturierung after completion of bone growth is no longer sufficient.
For these cases, the Cartilage bone transplants called OATS on ankle available.
What is a bone-cartilage transplantation or OATS?
Unlike the case of cartilage transplantation are cartilage bones are round cylinders from a polluted region of a few joints removed and transplanted. (often the knee joint)
The cartilage-bone cylinder is made of bone and cartilage intact coating. This cylinder is similar to the piles at the house in the swampy terrain in the background of the fixed bone cartilage bone damage eingepresst. Several of these cylinders can be great damage or even just an individual.
If several of these cartilage-bone cylinders set side by side, this effect on the viewer like a mosaic of circular cartilage lids. We call this type of cartilage therapy therefore MOSAIKPLATIK.
At the upper ankle bone is cartilage transplantation often only after a planned Knochendurchtrennung (osteotomy) during the surgery. This is after the end of the operation once again locked, so put on healing. For example, the inner part of the ankle often the inner ankle temporarily detached to the anklebone damages to be accommodated.
This is in the upper ankle joint, not only at the anchor leg or Talus possible but also to the gelenktragenden shares of the tibia. On foot, this method more and more on cartilage bone injuries, Knochentod (Knochennekrosen) or the metatarsal heads Früharthrosen used.
What goals would be with the body's own cartilage-bone transplantation achieve?
The aim of the cartilage-bone transplantation is a bone-cartilage injury in as' full 'cartilage to replace. This should receive the joint and a rapid emergence of arthritis can be avoided. Even the dead bone replacement is sought. The restoration of a pain-free joint function is the main target of the operation.
Who can by a cartilage-bone transplantation in the ankle joint benefit?
Patients who suffer an accident or a circulatory disturbance of cooking a defined cartilage-bone injury, or a cavity formation in the cartilage have suffered.
What should you look for the bone-cartilage transplantation on the ankle joint observed?
Initially, an immobilization of the ankle with a rail in neutral position. This phase lasts until the wound secured about 12 days. On the first day after surgery with physiotherapy should be initiated to ensure the mobility of the ankle and the muscles to maintain. Treatment with a motor-driven movement of the rail joint (CPM-rail movement) can be particularly effective because of the cartilage recommended. A discharge of the ankle for at least six weeks is necessary. After X-ray control with solid bone conditions may increasingly be burdened. A thrombosis prophylaxis should continue until the full load required.
