Articular cartilage repair (MACI) at Spire Claremont Hospital

Articular cartilage is the weight-bearing surface in joints, and cannot repair itself. Injury to articular cartilage typically causes pain on activity, catching and swelling of the joint. If left untreated, degeneration and eventual osteoarthritis can result. Sports injuries are the prime cause of cartilage damage in 16-50 year olds.

Some treatment options aim to create a ‘scar’ over the damage. Chondrocyte transplantation (MACI), however, is durable treatment that can regenerate the damaged cartilage.

MACI is typically considered for cartilage damage that causes symptoms in a knee that is not unstable, and in a patient motivated for rehabilitation. For very small areas of damage other treatments can be effective, for larger areas of injury, however, MACI can be the best solution.

A sample of the patients' own cartilage, harvested by keyhole surgery, is grown and expanded in a laboratory. These cells are then re-implanted in the damaged area.

We are committed to delivering excellent individual care and customer service across our network of hospitals, clinics and specialist care centres around the UK. Our dedicated and highly trained team aim to achieve consistently excellent results. For us it's more than just treating patients, it's about looking after people.
