What is Hip Microfracture Surgery?
The Microfracture procedure was developed to promote the growth of cartilage like tissue in an injured joint. Because of the lack of blood supply within the chondral layer, it is thought to be impossible for cartilage to regenerate itself. Microfracture is performed so that a fresh set of marrow cells and blood supply can be introduced to the damaged area, thus helping to promote production of a fibrocartilage layer to cover the exposed bone. During this procedure, small holes are made in the area of exposed bone creating “microfractures” allowing the bone marrow elements and stem cells to flow into the joint. These fractures are meant to provide a source of marrow stimulation and cells for new cartilage growth. In most cases, a layer of fibrocartilage will form to cover the exposed bony defect. This type of cartilage is different than the normal articular cartilage found in joints, but provides relief of symptoms and preservation of the surrounding cartilage in the joint by covering the bone. If the joint is already worn out where there are large areas of missing cartilage or advanced arthritis, then the microfracture procedure has been shown to not work in these situations.
Recovery After Microfracture Procedure in the Hip
After a microfracture procedure, patients are encouraged to avoid full weight bearing on the affected limb for 6 to 8 weeks to provide an optimal environment for the cartilage to fill in. Dr. Boykin may choose to use a continuous passive motion (CPM) machine. During this recovery time, patients will avoid certain hip motions but will be allowed to move the hip with the guidance of a therapist.
