Background: Opening Wedge High Tibial Osteotomy (OWHTO) is a procedure used mainly for medial osteoarthritis of knee. As open angle gets larger, for mechanical support and facilitation of bony union, autogenous bone, allogenic bone or bone substitute is used. This study aims to analyze the radiographic results of application of granular hydroxyapatite and beta-tricalcium phosphate after OWHTO. Method: Patients who went through OWHTO surgery between 2015, February to 2019, November were selected. Pre, post-operatives impeller diagram were compared to assess for length and angle correction. Postoperative simple radiograph and computed tomography can were taken 1year after surgery to assess for gap filling, bony union and Hounsfield units score. Result: Mean correction angle was 13.29?; Mean gap length was 12.98 mm. Every cases how gap filling of more than zone 3. Ten cases which gained zone 3 gap filling gained mean angle correction of 16.14?, mean gap length of 6.97 mm. Eleven cases which gained zone 4 gap filling gained mean angle correction of 13.62?, mean gap length of 12.29 mm. Thirty-six cases which gained zone 5 gap filling gained angle correction of 12.53?, mean gap length of 11.89 mm. Every cases gained bony union and 1 case of superficial wound infection occurred. Conclusion: Gap filling occurred despite of large amount of correction angle and correction length. And radiographic osteo integrations were observed.
