Clinical application of the GIEBEL system in high tibial osteotomy / 中国矫形外科杂志

ABSTRACT

[Objective]To discuss the results of the GIEBEL system in high tibial osteotomy to treat varus knee.[Method]Nineteen patients with medium varus knee were selected to be treated with osteotomy.Preoperatively,the mean varus angle was 12.29?,without deformity in other department of the knee joint.The main symptom was the pain in medial department.Accurate high tibial osteotomy with GIEBEL system fixation was performed in 31 knees of these patients.Weight-bearing extremity X-ray testing,varus angle,mechanical axle and anatomical axle were marked preoperatively and postoperatively.Joint space discrepancy between lateral and medial joint,the range of motion,Lysholm assessment and objective satisfactory survey were also performed to determine the outcome of the treatment.[Result]The mean follow-up of nineteen patients was 22 months.During this period,one case of temporary common fibular nerve paralysis occurred and healed at several days.All of the osteomy interface achieved bony healing.The corrected abnormality was 12.32?.The mechanism axle of the extremity maintained as the level just after operation during the follow-up and no degeneration of the joint space aggravated.The excellent and good rate of the treatment was 89.5%,and 84.2% of the patients expressed satisfactory for the operation.No difference of the range of motion was found before and after operation,but the Lysholm score,joint space discrepancy between lateral and medial joint and varus angle were improved after the osteotomy.[Conclusion]The GIEBEL system can fixate the bony interface of the high tibial osteotomy effectively,and possess the advantages of minimal invasion,stronger intensity and higher healing rate.
