摘要
Patient-specific instrumentation(PSI)enables a more accurate alignment of the lower limbs in a high tibial osteotomy(HTO)than in traditional surgery;however,the current design of commercial PSIs is not perfect.Therefore,we designed a new patient-specific surgical guide to improve the accuracy of the osteotomy and verified its reliability through a clinical operation.Here,we describe a patient with isolated medial-compartment bilateral knee osteoarthritis,accompanied by a varus deformity of the proximal tibia.The patient was treated with HTO using a patient-specific 3D-printed surgical guide.We concluded that the patient-specific 3D-printed surgical guide improved the accuracy of the osteotomy and the alignment of the lower limb.
