Abstract

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.

摘要

胫骨平台畸形愈合（TPM）可采用关节内矫正截骨术恢复膝关节面的解剖位置，但精确恢复并不容易。个性化手术指南 (PSG) 可能会改善 TMP 结果。本研究开发了一种两阶段 PSG 方法，为后续的截骨术提供配准和钻孔。进行测试以比较建议的 PSG 和传统指南（前交叉韧带指南，ACLG）的准确性。结果表明，PSG 提供比 ACLG (1.58 ± 0.67 mm) 更好的精度 (0.50 ± 0.19 mm)。结果表明 PSG 方法是传统 ACLG 程序的可行替代方案。
