Because supracondylar-intercondylar fracture is frequently accompanied by severe soft tissue damage, comminution and intraarticular extension of fracture, it can produce some disability of the knee joint, So recently, early anatomical reduction, rigid internal fixation and early rehabilitation was recommended.

The authors analyzed twenty cases of supracondylar-intercondylar fracture that treated at the Department of Orthopaedic Surgery of Pohang Saint Marys hospital from March, 1990 to December, 1993.

The object of this study is to evaluate the corelation between the rigid internal fixation and early rehabilitation,

The average follow up period was 18.3 months(form 14 to 27 months,)

The results were as follows;

1, Among the twenty cases, male was more common than female and the prevalent age was 4th decade(50%).

2. The most common cause of injury was trafnc accident in 15 cases(75%).

3. During 1st 3weeks after operation, we started active R.0.M. exercise by using Thomas splint with Pearson attatchment and long leg brace with ischial weight bearing was applied from 3months to 6months (averge 4.2 months). We permit partial bearing Sweets after operation,

4. According to Schatzker and Lambert criteria, excellent were 16 cases, good 3 cases, feir 1 case.

5. We obtained satisfactory by rigid internal fixation and early rehabilitation.
