Jason L. Dragoo, MD, Professor and Vice Chair of Academic Affairs for the CU Department of Orthopedics, is an internationally known pioneer in the field of Biologics and Regenerative Medicine, as well as minimally invasive Sports Medicine procedures. He is the Endowed Chair of Regenerative Medicine and has developed many procedures designed to augment the healing of a patient’s own body. He strongly favors the use of autologous procedures (the use of the patient’s own tissue or cells for the procedure) versus allograft procedures (using tissue and cells from another human). Dr. Dragoo believes that joint restoration techniques, which add tissue back to a damaged joint, should be used whenever possible (e.g., cartilage and meniscal transplantation), rather than procedures that are designed to take tissue away (meniscal resection).

He approaches standard procedures such as ACL reconstruction, meniscal and tendon repair with a less-invasive approach than commonly performed. A significant number of Dr. Dragoo’s patients are elite athletes (professional, collegiate, or Olympic) but he welcomes athletic patients of all ages and treats them with the same philosophy and surgical or non-surgical techniques.

Dr. Dragoo was the Head Team for the Stanford University Football Program for 12 years before being recruited to Denver. He now treats many elite football athletes within the NFL, including the Denver Broncos. He is now the Head Team Physician for the Denver Nuggets NBA Team. He also treats many elite NBA and Collegiate basketball athletes from around the country.

Dr. Dragoo’s research has led to significant improvements in therapeutic or preventative treatments for the following disorders:

  • Female ACL tears
  • ACL revision surgery
  • Bone and joint pain from osteoarthritis
  • Tendinopathy
  • Arthrofibrosis (joint stiffness/loss of motion)
  • Fat pad disorders
  • Genetic predisposition to injury
  • Osteoarthritis after ACL tear
  • Cartilage transplantation techniques
  • Chondrotoxicity
