A common consequence of cartilage defects is swelling, pain, or immobility of the knee joint, which in the long term can lead to a reduction in weight-bearing capacity and even mobility. There are various treatment options. One of them is the so-called autologous chondrocyte implantation (ACI).
ACI has been around since the mid-1990s and has been steadily gaining popularity since around 2005. Most often it is used to treat cartilage defects in the knee, the ankle or the hip.
Within the method of ACI, CO.DON AG has developed a special technology – the spheroid technology: Three-dimensional cartilage cell implants – the spheroids – consisting of healthy cartilage cells and extracellular matrix are produced ex vivo in a laboratory and transplanted back into the cartilage defect to form new cartilage tissue.
Derived from this technology is the name of the product: SPHEROX. Its special feature: Spherox is 100% autologous, only the patient’s own cartilage cells are used for its production.of
Spheroids are spherical cartilage cell implants made from human chondrocytes and extracellular matrix to treat cartilage defects in the (knee) joint. Over a period of about 6 – 8 weeks they are produced in a laboratory and afterwards implanted as Spherox into the cartilage defect.
The model shows spheroids directly after implantation into the cartilage defect in the knee joint (model enlarged). Move the model with the mouse button and zoom in by holding down the CTRL key.
The spheroids are applied evenly into the defect. Just a few minutes later, they self-adhere to the subchondral bone. After about 20 minutes, the process is complete and the spheroids adhere firmly.
The model shows spheroids approx. 20 minutes after implantation into the cartilage defect of the knee joint (model enlarged).
During the following weeks and months after the implantation of the spheroids (Spherox), new hyaline-like cartilage gradually forms and integrates into the existing, healthy catilage. After successful treatment and personalised rehabilitation, the knee can bear weight again.
The model shows how new hyaline-like cartilage tissue has formed in the cartilage defect.

When twelve-year-old Anna is playing with her dog, she twists her left knee. An operation at the hospital does not bring the hoped for solution: the pain remains and she is threatened with an artificial knee joint. A new treatment method could help, but it is – at that time – only indicated fort he use in adults. A long struggle begins.

Artificial knee joint or cartilage cell therapy? Christian Florkiw-Jenkner talks about the treatment of his cartilage defect with SPHEROX and how it helped him to play sports again without pain.
Klara Tomsova cannot imagine her life without sport. Severe pain in her knee, forces her to give it up. Until a treatment with SPHEROX enabled her to return to an active life.
The information website for patients and those interested in the topic of cartilage defects offers a lot of interetsting information and possible treatment options.
