There are a variety of biological treatments available for early cartilage damage. The most common of these surgical techniques, Microfracture, was developed over 20 years ago and is considered a first line treatment. During arthroscopy (knee scope), 2-3mm wide fractures or “bone channels” are created to access stem cells within the bone marrow. These cells then stimulate the cartilage repair process.
In a recent study, Dr. Madry and his team from Saarland University, Homburg, Germany, compared 1mm and 1.8mm diameter bone channels. The study concluded that the smaller, 1mm, bone channels created less damage to the bone and were better for cartilage repair than the wider 1.8mm bone channels.
Over 2 years ago, Arthrosurface introduced NanoFracture that creates 1mm wide bone channels. Some of the benefits and improvements of the Nanofracture system are:
