Dr. G. Mark Sylvain is a great doctor. He fixed my knee after One and a half years of constant pain. I fell on 1/29/2014 and tore my meniscus cup in two places. Dr.Kirk Mendez first tried to repair the knee. Six months later said I needed a total knee replacement. After I woke up from surgery my knee looked twisted. Even with the bandages I could tell something was wrong. I tried to speak to the Physical Therapist who was to get me up walking. I went into Dr. Mendez office for a year and a half before he finally admitted something was wrong. Dr. Thompson is the doctor one must see to excess if surgery is needed. It was. A bone scan showed abnormalities. So he referred me to Dr Sylvain. He put me into surgery with a week. My knee looked so much better, and the constant pain was not there. Thank You Dr.Sylvain. And the Orthopedic Specialist Of Nevada.
