A total of 78 high tibial osteotomies —70 for valguization and 8 for varization—in 60 patients were reviewed. I all cases, the osteotomy was stabilized by a new staple designedwith compressive effect, due to the elasticity of the material used. The follow-up of the patientsranged from 3 to 10 years. According to Coventry's criteria (1973), good results were obtainedin 61 osteotomies (78%), fair in 11 (14%) and poor in 6 (8%). Neither loss of correction normigration of the staple were detected. Complications were found as paresia of the extensorlongus of the first toe in one case, infection of the soft tissues in 2 cases and persistingpostoperative edema of the lower extremity in other 2 patients. Healing of the osteotomy wasachieved in 49 days average (range, 30-67). The new compressive staple permit to reduce oreliminate postoperative plaster inmovilization, facilitate an early knee rehabilitation, and diminishthe risk for loss of correccion.
