title: Acute traumatic hemarthrosis of the knee. Is routine arthroscopic examination necessary? A study of 320 consecutive patients.
abstract: OBJECTIVE
  Distortions and contusions of the knee are common. Fairly often they will result in hemarthrosis. The purpose of this study was to evaluate the findings in patients with acute traumatic hemarthrosis of the knee and based on these findings estimate the necessity of acute arthroscopic examination.
  
  
  METHODS
  A total of 320 patients were examined arthroscopically between the years 1994 to 96 in the Turku University Hospital. Patients with other than chondral or osteochondral fractures were excluded.
  
  
  RESULTS
  The most common arthroscopic findings were rupture of the ACL (45%), dislocation of the patella (23%) and meniscal tear (21%). In only 113 (35%) cases an immediate therapeutic procedure was performed in addition to the arthroscopic examination.
  
  
  CONCLUSIONS
  Based on our findings we believe that routine arthroscopic examination is not necessary in patients with acute traumatic hemarthrosis of the knee. In our opinion the patient should be examined and followed by an orthopedic surgeon and if a lesion requiring operative treatment is diagnosed or suspected, an arthroscopic examination should be scheduled. The timing of the procedure should be such that all possible lesions encountered can be treated in the same operation.
