PURPOSE
To assess the accuracy of knee alignment after high tibial osteotomy (HTO) for varus knee deformity using arthroscopy-assisted computer navigation.
METHODS
Six men and 4 women aged 47 to 53 (mean, 49) years underwent medial open wedge HTO for varus knee deformity and medial unicompartmental osteoarthritis using arthroscopy-assisted computer navigation with fluoroscopy. Patients were followed up for a mean of 23 (range, 11-32) months. Intra- and post-operative leg alignments were compared.
RESULTS
The mean postoperative coronal plane alignment was 2.7 (range,1-4) degree valgus; the mean deviation from intra-operative computer images was one (range, 0.1-1.9) degree; 5 knees had less valgus in the postoperative radiographs than the intra-operative computer images.
CONCLUSION
Despite being more technically demanding, time consuming, and costly, arthroscopy-assisted computer navigation is safe, accurate, and reliable for HTO.
目的
使用关节镜辅助计算机导航评估胫骨高位截骨术（HTO）治疗膝内翻畸形后膝关节对线的准确性。
方法
6名男性和4名女性，年龄47至53岁（平均49岁），因膝内翻畸形和内侧单髁骨关节炎接受关节镜辅助计算机导航结合透视的内侧开放楔形HTO手术。患者平均随访23个月（范围11 - 32个月）。比较手术中和手术后的下肢对线情况。
结果
术后冠状面平均对线为2.7°（范围1 - 4°）外翻；与术中计算机图像的平均偏差为1°（范围0.1 - 1.9°）；5个膝关节术后X线片上的外翻角度小于术中计算机图像显示的角度。
结论
尽管关节镜辅助计算机导航技术要求更高、耗时更长且成本更高，但对于HTO手术来说是安全、准确且可靠的。
