Objective To investigate the influence of medial high tibial osteotomy(HTO)on the effect of knee osteo-arthritis and cartilage lesion of knee joint lateral compartment.Methods A total of 104 patients who suffered from u-nilateral varus knee osteoarthritis were treated by medial HTO.Arthroscopy was performed again to explore the pro-gression of cartilage lesions in the lateral compartment of the knee joints.They were divided into three groups accord-ing to the cartilage lesion grading of knee joint lateral compartment at osteotomy,group A(Outerbridge degree-Ⅰ,41 cases),group B(Outerbridge degree-Ⅱ,35 cases)and group C(Outerbridge degree-Ⅲ,28 cases).The pan VAS,Ly-sholm scores,WOMAC scores and the cartilage lesion changes of the knee joint lateral compartment in the re-operation were recorded.Results All cases were followed up for 12～32(20.19±4.65)months.The pain VAS,Lysholm scores,WOMAC scores of the three groups were improved in the re-operation than the primary surgery(P<0.05).Before the re-operation,there was no statistical difference in pain VAS between groups A and B(P>0.05),but both groups were better than group C(P<0.05),there were no statistical differences in Lysholm scores and WOMAC scores among three groups(P>0.05).Among three groups,the maximum diameter of cartilage lesion of the knee joint lateral compartment had no differences between the secondary operation and the primary surgery(P>0.05).Conclu-sions For the patients with cartilage lesion(Outerbridge degree Ⅰ～Ⅲ)in the lateral compartment of the knee joint,HTO does not increase the cartilage degeneration of lateral compartment,it can still obtain more satisfactory clin-ical effect.
