Microfracture surgery

Microfracture surgery (pronunciation: /ˈmaɪkrəˌfrækʧər ˈsɜːrdʒəri/) is a minimally invasive arthroscopic surgery procedure that is used to repair damaged articular cartilage in the knee by creating tiny fractures in the underlying bone. This procedure stimulates the body's natural healing response, leading to the growth of new cartilage.

Etymology

The term "microfracture" is derived from the Greek words "micros" meaning small and "fracture" meaning break. The term "surgery" comes from the Greek word "cheirourgia" meaning "hand work".

Procedure

Microfracture surgery is performed using an arthroscope, a small camera that allows the surgeon to view the inside of the joint. The surgeon first removes any damaged or loose cartilage and then uses a small, sharp tool to create tiny fractures in the underlying bone. These fractures stimulate the body's natural healing response, leading to the growth of new cartilage.

Risks and Complications

As with any surgical procedure, microfracture surgery carries some risks, including infection, blood clots, and damage to surrounding structures. The success of the procedure also depends on the patient's age, the size and location of the cartilage defect, and the patient's commitment to postoperative rehabilitation.
