Los Angeles (LA), California is a world renown metropolitan area and entertainment capital of the world. Dr. Dennis Lox is an expert in stem cell treatment of avascular necrosis (AVN), and treats AVN with stem cell therapy in LA, California. Avascular necrosis occurs when the blood supply to a region of bone becomes impaired leading to bone cell death or necrosis. Stem cells have been used as a Regenerative Medicine strategy for the treatment of AVN. Avascular necrosis is often associated with a rapid degenerative arthritis if the necrotic region of bone collapses. This complication of AVN often leads to recommendations for total joint replacement surgery or joint fusion. Athletes and younger patients especially are looking for alternatives to joint replacement surgery as the lifespan of joint implants is inadequate during the patients lifetime, and revision surgery is often needed. Stem cells for AVN may provide an alternative treatment strategy for some patients with AVN. Los Angeles (LA), California is home to numerous professional sports franchises, and with LA’s favorable climate an active sporting lifestyle is common. Trauma is the most frequent cause of AVN, and sports injuries may result in the development of AVN. Stem cells may provide athletes with AVN additional options to continue their sports career or sports participation. Dr. Lox practices Sports and Regenerative Medicine in the Los Angeles (LA) community of Beverly Hills.
