Abstract: Objective To evaluate the clinical effect of tibial plateau bone defects repair using osteotomy and bone grafting with autogenous bone gain way in total knee arthroplasty.Methods From Mar.2011 to Mar.2015,28 knees of 20 patients with bone defects in medial tibial plateau were in total knee arthroplasty,the bone defects were repaired into horizontal steps,then with autogenous bone grafting by osteotomy.Results The bone defects could be repaired effectively to support the knee joint prosthesis,all the patients were followed-up through outpatient from 1 year to 4 years with the average of 2.6 years,the HSS kness score increased from (20.9 ± 1.2) before opearation to (87.6 ± 1.6) after operation.Hss score were paired t test,there was statistically significant difference (P ＜ 0.05).The location was good and there was no bone defect image,no bone resorption and no joint dislocation under X-ray.Conclusions To repair the bone defects in total nkee arthroplasty,it can use the autogenous bone by osteotomy reasonably,achieve good repair defect site,reserve the bone mass maxium,reconstrust the balanced mechanical support of tibia.
