What is primary care sports medicine and how is a primary care sports med doc different from an orthopedist who does sports med?

Surgery. A primary care sports medicine doctor can do a fellowship just as an Orthopaedic Surgeon with a sports fellowship. The main difference is that the Orthopaedic surgeon can actually operate and repair injuries. Both doctors can diagnose and treat sports related injuries.
PCSM. A primary care sports medicine doctor is someone who has trained in primary care, family medicine, internal medicine, pediatrics, emergency medicine and further trained in sports medicine. They are non-operative so they do not operate like an orthopedist does. They treat nonsurgical injuries to the musculoskeletal system. They focus on prevention and minimally invasive/noninvasive treatment.
