Microstructural scaffold (patch) insertion without autologous cell implantation for repairing symptomatic chondral knee defects

The condition

Damage to the cartilage on the ends of the bones in the knee (known as chondral damage) can be caused by injury or arthritis. In young people, the most common cause is sporting injuries. It can also occur spontaneously (called osteochondritis dissecans). Symptoms include pain, swelling, instability, joint catching and locking. The condition can lead to osteoarthritis. Treatment options depend on the size of the defect and where it is. Treatments aim either to relieve symptoms or to regenerate the cartilage surface.

NICE has looked at using microstructural scaffold (patch) insertion without autologous cell implantation as another treatment option.
