Arthroscopic radiofrequency chondroplasty for discrete chondral defects of the knee

The condition

The cartilage over the ends of bones in the knee (articular cartilage) can be damaged by trauma, leading to small defects (called discrete chondral defects). These defects can cause the joint to become painful, swollen and difficult to move. The condition is usually chronic and can lead to osteoarthritis.

Treatment options depend on the size and site of the defects. They include non-steroidal anti-inflammatory drugs, corticosteroid injections or hyaluronic acid injections to relieve pain and inflammation. Physiotherapy and exercise may also be used to help improve knee function and mobility.

NICE has looked at keyhole surgery using radiofrequency chondroplasty as another treatment option.
