The Whiteside knee prosthesis has been used in total knee replacement operations in our hospital since 1987. Although follow-up is only of a relatively a short period, the treatment results were studied clinically and radiologically.Subjects were patients who were examined directly, including 13 cases (18 knees) of gonarthrosis (OA) with a mean age of 68.5 years. The observation period of the postoperative course was from 15 to 41 months with an average of 27.0 months.Clinical evaluation was performed using the OA knee evaluation criteria of the Japanese Orthopaedic Association, while radiological evaluation was made by measuring the insertion angles of each of the components directly post-operatively and on final follow-up examination.The overall clinical evaluation scores showed improvement of 46.0 to 78.0, but there was slight decrease concerning the range of motion. Radiologically, radiolucent zones and sinking, but no loosening, were seen in patients not using screw or sleeves.
