High tibial osteotomy without internal fixation for medial unicompartmental osteoarthrosis

Between 1982 and 1993, a total of 35 patients underwent high tibial osteoto my for medial unicompartmental osteoarthrosis. The osteotomy was performed high in the tibia without the use of jigs, and internal fixation devices we re avoided. Patients were assessed using the British Association for Surger y of the Knee score, and satisfactory results with minimal complications we re obtained. Our results indicate that in a select group of patients, high tibial osteotomy preserves bone stock and is performed near the deformity s o that excellent correction is achieved and recurrence of varus deformity i s avoided.
