Microfracture Knee Surgery

Microfracture knee surgery is a relatively new technique developed to help repair damaged cartilage in the knee. It is a technique that helps provide people an option other than having total knee surgery as a treatment for certain knee injuries. Microfracture surgery is considered less invasive and can take only hours for doctors to do. This can also mean lesser time for the patients to recuperate and get back to their normal lives after the procedure.

Surgical Procedure

Microfracture knee surgery is done as part of an arthroscopic knee surgery. It makes use of a long and thin scope called an arthroscope that allows the surgeon to work on a particular area on the knee less invasively. The procedure is usually done with the doctor making a small quarter inch surgical cut on the affected knee. This is where the arthroscope goes in. The surgeon then makes use of a special tool called an awl to drill small holes called microfractures in the affected area in the knee joint cartilage.

How It Works

When the surgeon makes tiny holes in the bone, it allows the harder layer of the bone to have tiny fractures that allow the interior bones to gain access towards the outer surface. With the interior bones usually having better blood supply, the microfractures allow the blood cells to get into the surface layer and stimulate cartilage growth. Blood cells from the bone marrow inside the bone are sent to the surface that also help build up new cartilage on the surrounding area.

Possible Candidates

Microfracture knee surgery is usually a common procedure done in most athletes. Their activities can be physically demanding to a point where damage on knee cartilage develops and causes pain as well as prevent them from becoming more efficient. But aside from athletes, microfracture knee surgery can also be done on people with mild to moderate knee injuries caused by cartilage damage. People with early arthritis can also benefit from the procedure to ease the pain on their knees. People with lesions on the kneecap may also be a good candidate for this surgical procedure.
