Methods: A prospective case series was conducted, including patients with medial osteoarthritis undergoing open-wedge high tibial osteotomy. In the preoperative planning, the picture-archiving and communications system-photoshop method and real-size paper template method were used simultaneously in all patients. Preoperative hip-knee-ankle angle, height, and angle of the osteotomy were evaluated. The reliability of this newly devised method was evaluated, and the consistency between the two methods was also evaluated using intra-class correlation coefficient. Results: Using the picture-archiving and communications system-photoshop method, the mean correction angle and height of osteotomy gap of rater-1 were 11.7°±3.6° and 10.7±3.6mm, respectively. The mean correction angle and height of osteotomy gap of rater-2 were 12.0±2.6 and 10.8±3.6, respectively. The inter- and intra-rater reliabilities of the correction angle were 0.956~0.979 and 0.980~0.992, respectively. The inter- and intra-rater reliabilities of the height of the osteotomy gap were 0.968~0.985 and 0.971~0.994, respectively (p<0.001). Using the real-size paper template method, the correction angle and height of the osteotomy gap were 11.5°±3.4° and 10.9±3.8mm, respectively. Using the picture-archiving and communications system-photoshop method, mean values of the correction angle and height of the osteotomy gap were 11.9°±3.6° and 10.8±3.6mm, respectively. Consistency between the two methods by comparing the means of the correction angle and the height of the osteotomy gap were 0.985 and 0.985, respectively (p<0.001). Conclusions: Use of the picture-archiving and communications system-photoshop method enables direct measurement of the height of the osteotomy gap with high reliability. Level of evidence: III.
