From September 2001 to September 2003, medial opening HTO was performed in twenty patients who had a mean age of 67 years. Beta-TCP with 75% porosity was grafted to all bone defects. The results showed that the standing femorotibial angle was corrected from 181 degrees preoperatively to 170 degrees at the time of the latest follow-up. No correction loss had been found and bone formation was noted in all cases. The surgical technique used in this study did not require fibula osteotomy and it may produce few problems when TKA is necessary in the future. Autologous iliac bone graft was used until April 2003. However, since May 2003, the use of beta-TCP block with 60% porosity, which was 7.5 times stronger in terms of compression strength, allowed avoidance of autogenous bone grafting and shortening of the surgical time.
