Intra-articular corrective osteotomy can be used to restore the anatomic position of knee surfaces for tibial plateau malunion (TPM) but precise restoration is not easy. The personalized surgical guide (PSG) might improve the TMP outcomes. This study developed a two-staged PSG method to provide registration and drill the bone for subsequent osteotomy. The tests were performed to compare the accuracy the proposed PSG and the conventional guide (Anterior cruciate ligament guide, ACLG). The results showed that the PSG provides better accuracy (0.50 ± 0.19 mm) than the ACLG (1.58 ± 0.67 mm). The results show the PSG method is a feasible alternative to the conventional ACLG procedure.
关节内矫正截骨术可用于恢复胫骨平台畸形愈合 (TPM) 的膝关节面解剖位置，但精确的复位并不容易。个性化手术导板 (PSG) 可能会改善 TPM 结果。本研究开发了一种两阶段 PSG 方法，用于提供注册和钻孔骨以进行后续截骨术。进行了测试以比较所提出的 PSG 和传统导板（前交叉韧带导板，ACLG）的准确性。结果表明，PSG 比 ACLG（1.58 ± 0.67 毫米）提供更好的准确性（0.50 ± 0.19 毫米）。结果表明，PSG 方法是对传统 ACLG 手术的可行替代方法。
