Fracture of tibial intercondylar eminence has a clinical importance in aspect of associated ligament injury, limited range of motion and joint instability. The purpose of this study is to evaluate the intercondylar eminence fracture and to compare the results of treatment by method of arthroscopic reduction and pull-out suture with results of conservative treatment. The results were evaluated with Mayers and McKeever' s criteria of result and instability. 23 cases of avulsion fracture of tibial intercondylar eminence were reviewed. Most common type was type II. Most common cause was traffic accident. Closed reduction and cast immobilization was performed in 12 cases, of which 10 cases had above good result initially, reduction with pull-out suture by arthroscopy was performed in 11 cases, of which 10 cases had above good result. Type IIIB fracture were reduction with minimal arthrotomy because of the arthroscopic reduction was difficult. 2 cases of instability were in type IIIA and type IIIB. An instability case of type IIIA was treated non-operatively and the other of type IIIB was treated pull-out suture. I case of extension limitation was in type II which was treated non-operatively because of multiple injury.
