ONS orthopaedic surgeon Demetris Delos, MD, was a featured guest on Pleasantville Community Television’s series, Health IQ, hosted by Dr. Alan Siegel of ProClinix. During the fascinating thirty-minute interview, Dr. Delos, a specialist in knee and shoulder conditions, spoke in detail about common cartilage, ligament and tendon injuries. Age, gender and type of activity can play a role in a person’s susceptibility to orthopedic problems, he said. Using models and computer generated images, Dr. Delos described the non-surgical and surgical options to repair or replace damaged tissue and joints.  Functional and strength training, he stressed, are key for injury prevention and rehabilitation. Dr. Delos also provided a glimpse into future treatments including the development of synthetic tissue products and the advances in biologic medicine which uses biomedical materials such as blood, platelets and stem cells to treat pain and complex, often chronic conditions of the musculoskeletal system.
