PurposeIt is the consensus of Joint Clear Operation and High tibial osteotomy are effectiveOperation On the Treatment of the Osteoarthritis of Knee.It’s Limited to the KneeArthroplasty to the early stages of the Osteoarthritis of Knee,and it has its drawbacks ofhigher expenses and pains in the treatment.In this study,it is treated with a single stageoperation., relieved pains,reduced costs and recovered the functions of knees.Method34cases of knee OA were performed Joint Clear Operation and High tibial osteotomywith EDTQ self-made external fixator。Among them,5were male and29were females1Theage of patients ranged from52to62years (averaged56years), and the range of genuvarum angle were from6°to13°(averaged10°).The mean score according to HSS kneejoint standard was34.7.After operation, functional exercise was guided and Geun Varumand Valgum was corrected by prolonging Unilateral external fixator.Joint mobilization wasencouraged when the gravity line in lower limb was corrected gradually.ResultsAll cases which were followed2up from6months to1years (averaged11months)postoperatively had got good fusion, and the movement of the knee had the same range aspreoperation1.The meancorrected angle of genu varum was10°, FTA achieved to3°ofeversion1.The mean score according to HSS standard was82,which had achieved47.3than preoperation.ConclusionHTO can apparently correct the weight loading axis of knee OA withgenu varum andimproved the blood supply in locus, decrease the pressure in the tibial1.EDTQ self-madeexternal fixator which had simple design and reliable fixation can control the osteotomyangle accurately, and are ideal choice of fixation for HTO.
