title: A rare cause of chronic elbow pain in an adolescent baseball player: a case report.
abstract: OBJECTIVE
  To present a case of chronic elbow pain as a result of a hidden underlying osteochondral defect.
  
  
  METHODS
  A 17-year old baseball player presented with chronic lateral elbow pain. Examination revealed swelling of the elbow with signs of possible ligament, muscle, and tendon injury.
  
  
  METHODS
  Although there was apparent soft-tissue injury, the elbow swelling created immediate suspicion of a more serious underlying condition. Examination revealed a swollen and tender elbow, with plain x-ray confirming a subchondral bone disorder (osteochondral defect) of the capitellum. Surgical repair was performed by an orthopedic surgeon using DeNovo NT Natural Tissue Grafts: the implantation of small pieces of juvenile joint cartilage into the affected area, using glue-like fibrin. Rehabilitation of the elbow began immediately following surgery.
  
  
  CONCLUSIONS
  Examination and imaging indicated that elbow pain in an adolescent baseball player could be from multiple sources, however, the chronic swelling raised suspicion of a condition requiring immediate and further investigation.
