title: Arthroscopic removal of patellar fracture fragments in horses: five cases (1989-1998).
abstract: OBJECTIVE
  To evaluate the use of arthroscopy as the primary method for removal of large patellar fracture fragments.
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  5 performance horses of various breeds with patellar fractures.
  
  
  METHODS
  Clinical signs of lameness, external evidence of injury, and radiography were used to diagnose and determine fracture orientation. Arthroscopy of the stifle joint was performed on the affected limb with the horse positioned in dorsal recumbency and under general anesthesia. Progress after surgery was determined by evaluating medical records and via telephone conversations with owners.
  
  
  RESULTS
  4 of 5 horses had fractures of the medial aspect of the patella and 1 horse had a fracture of the lateral aspect of the patella. There were no postoperative complications with the joint or the arthroscopic portal incisions. Recovery periods ranged from 3 to 5 months. All horses recovered completely from surgery, and performed at the same or higher level of competition as before arthroscopy.
  
  
  CONCLUSIONS
  Femoropatellar joint arthroscopy is a favorable means by which evaluation of the stifle joint and removal of large fracture fragments can be achieved with negligible postoperative complications.
