title: Chondromalacia of trochlear notch after healing of olecranon stress fracture: a case report.
abstract: BACKGROUND
  Chondromalacia of the trochlear notch and stress fracture of olecranon are uncommon injuries in the throwing athletes.
  
  
  METHODS
  We report an 18-year-old high school pitcher who had persistent postero-lateral elbow pain after a healed olecranon stress fracture of the right elbow. Diagnostic arthroscopy revealed chondromalacia of the trochlear notch.
  
  
  RESULTS
  After treatment with arthroscopic drilling and abrasion chondroplasty, he returned to competitive pitching 1 year later postsurgery. This rare association between chondromalacia and stress fracture of the olecranon has not been reported previously in the literatures.
  
  
  CONCLUSIONS
  Chondromalacia of the trochlear notch should be included as a differential diagnosis in evaluating athletes with persistent elbow pain after healed olecranon stress fractures.
