There have been different methods of high tibial osteotomy (HTO) for osteoarthritis of the knee. We developed an osteotomy drill guide block and angle correction measurement device to achieve accurate dome-shaped osteotomy and obtain the desired correction angle. Osteotomy was performed by percutaneous drillings. Since 1991, we have perormed percutaneous HTO in 54 cases (9 men, 45 women).The mean follow up period was 21 months. The Japanese Orthopaedic Association (JOA) score was used to clinically evaluate the results. The average postoperative score was 80, while the average preoperative score was 60, demonstrating the improvement. The preoperative femoro-tibial angle (FTA) was 184 degrees and the postoperative FTA was 168 degrees. There were no patients who showed serious peroneal nerve palsy.Our procedure has the advantage of being easy to perform as well as being less invasive because the ostotomy is performed by percutaneous drillings. It was considered that percutaneous HTO with an Orthofix external fixator allows early movement and maintains an accurate correction angle.
