Abstract：Objective To compare the results of high tibial osteotomy above and below tibial tubercle for early unicompar-tmental knee osteoarthritis with varus. Methods This retrospective study included 100 patients with medial early unicompart-mental knee osteoarthritis with varus from June 2006 to June 2013. Fifty patients had high tibial open wedge osteotomy above the tibial tubercle(TT)(group I). And the other 50 had the osteotomy just below it(group Ⅱ). The two groups were matched. All patients were followed up radiographically and clinically for more than 20. 5 months,clinical and radiographic results of both groups were comparable. Results There was no significant difference in the amout of correction achieved by the two tech-niaques,however,in the amount of correction loss at final follow-up,with a significantly smaller correction loss being seen after osteotomy below tibial tubercle. The osteotomy below tibial tubercle did not change in patella height from preoperative to final follow-up. Conclusion This leads to the conclusion that the below TT osteotomy gives more advantages by effectively correc-ting the deformity without creating any new soft tissue or bony abnormalities to the knee.
