Articular cartilage defect

Pain in the knee joint is often the result of cartilage damage. Left untreated, the defect becomes larger over time – the joint deteriorates until an artificial knee joint often the only solution is. Only high-quality chondrocytes enable the precise, lasting treatment of cartilage defects.

In a first arthroscopic ambulatory operation we remove a small piece of your cartilage from the affected joint and send it to a specialized laboratory for cell culture together with a blood sample.

In a special cell culture process we produce special three-dimensional chondrocyte spheroids in the laboratory within approximately five to seven weeks - without using any extraneous substances.

In a second minor arthroscopic ambulatory operation the spheroids will be inserted back into the lesion, where they adhere naturally and form new cartilage tissue that combines with existing healthy cartilage.

Following the chondrocyte transplant you stay in a hotel with daily consultations in our outpatient clinic and then begin a training program that has been carefully coordinated with the healing process. To protect  cartilage  growth during the first six weeks only partial weight bearing is permitted. From week seven your training program will continue increasing the load until you can have full use of your joint again.
