Tibial osteotomy for osteoarthrosis of the knee.

Forty-five knees with tibial osteotomy for osteoarthrosis were studied at 5 to 10 years following surgery. Twenty-seven were graded excellent, eight good and ten poor. The best results were found in knees which maintained a Femoro-Tibial angle of 163 degrees--180 degrees whereas the poor results were associated with either under-correction at operation or late recurrence of deformity. The latter was closely related to pain. Provided that the initial deformity is adequately corrected and maintained, tibial osteotomy for osteoarthrosis of the knee gives good results which can last up to 10 years.
