The treatment of the tibial piateau fractures has been under discussion for several decades, but no final answer has been reached. But many surgeons today believe that open reduction and internal fixation of commninuted, severly depressed, or displaced fractures are indicated

The goal of the surgery is anatomic reduction of joint surface, rigid fixation, and early range of motion. This retrospective study evaluated 40 cases of tibial condylar fractures that treated surgically at the Department of Orthopaedic Surgery Kyungpook National University Hospital from February, 1991 to August, 1995. The minimum follow up period was 13 months and average follow up period of the patients was 33 months.

The obtained result were as follows:

1. There were forty patients treated by surgically, the mean age was forty-six, and thirty patients were male, ten patients were female., thirty-one patients involved in motor vehicle accidents.

2. The most common type of the fracture was SchatBker type II in 10 patients., the most common associated soft tissue injury was rupture of the ipsilateral medial collateral ligament.

3. The most common method of the treatment was minimal screw fixation and bone graft in 20 cases.

4. The thirty-one cases (77.5%) had satisfactory result according to the Blokkers criteria among 40 cases. There were 2 superficial infections and 1 deep infection for post operative complications.

5. We had good result by anatomical reduction of the articular surfaces and early knee motion and delayed weight bearing for the treatment of the displaced, comminuted tibial condylar fracture.
