Objective To investigate the application effect of proximal tibial osteotomy guide device without locating rod in total knee arthroplasty(TKA).Methods The proximal tibial osteotomy guide device without locating rod was used for osteotomy localization of 40 cases undergoing TKA.The error value of varus-valgus angles and posterior slope of tibial prosthesis(both were difference from preoperative plan),the incidence of postoperative complications,knee flexion range of motion,pain VAS and knee HSS score were recorded.Results All patients were followed up for 12～56(28.2±6.1)months.Postoperative X-ray showed that the varus-valgus angle error of tibial prostheses was 0.3°～1.7°(1.0°±0.2°),and the posterior slope error of tibia prostheses was 1.1°～3.0°(2.0°±0.4°).All wounds healed normally.After surgery,there was no complications such as loosening and displacement of the prostheses,deep infection,deep vein thrombosis,pulmonary embolism,neurovascular injury.At the last follow-up,all patients could walk with full weight-bearing,with normal gait.Knee flexion motion,pain VAS and knee HSS score were improved than the preoperation(P<0.05).Conclusions Proximal tibial osteotomy guide device without locating rod is easily operated and reliable technique for the TKA.
