The tibial condyle fracture was descirbed first by Cooper in 1825, which involves articular surface of the proximal tibial and often pnduces disabilities of the knee joint due to accompanied by injuries to ligaments and menisci, frequently.

There are much controversies in the method of the treatment in the fracture of the tibia condyle, but todays, the anatomical reduction and firm internal fixation is recommanded with early knee motion for good results.

The authors analyzed 43 cases of tibia condylar fractures that treated at Department of Orthopaedic Surgery, College of Medicine, Dong-A University from March 1990 to May 1995.

The results were obtained as follows:

1. The most common age group was 4th decade.

2. The most common cause of injury was motor vehicle accident in 28 cases(65.1%) and others were slip down, fall down and sports injury, etc.

3. According to Schatzkers classification, thr most common type was type II and VI in 10 cases(23.3%) individually.

4. The most common soft tissue injury was ligament injury in 16 cases(37.2%), and the most common associated fracture was fibular fractures(13 cases).

5. By Porters criteria, 16 cases(76.2%) among 21 conservative cases and 16 cases(12.7%) among 22 operative cases had acceptable results.

6. The most common complication was limit of motion of knee joint(8 cases) and then, traumatic arthritis, angular deformity, infection, joint instability were seen.

7. There was no different result between conseHative and operation method in our study, but we think the simple comparision was meaningless because of the degrees of injury to the objects of the two treatment methods were different.

8. The factors to effect the prognosis were as fellows; the depression, displacement of the fracture, soft tissue injury, anatomical reduction and early knee exercise, etc.
