We clinically and roentgenologically reviewed 14 patients who had unilateral curved varus osteotomy following Chiari's osteotomy and 11 patients (12 joints) who had curved varus osteotany performad following the shelf operation. All operations had been performed a minimum of three years preuvously.
Results were as follows:
1. Clinical evaluation using the Japan Orthopedic Association's criteria was excellent in both groups.
2. Shortening of the leg length following curved varus osteotomy was 4.7mm on average (Range: 0-10mm).
3. The collodiaphyseal angle of the femur decreased from 152 to 121 degrees on average.
4. The distal femoral bones shifted 6.3mm laterally average (except 3 Joints).
