Abstract
From 1975 to 1986, 102 high tibial osteotomies for varus gonarthrosis were performed in 99 patients. Fifty-eight patients (60 knees) were re viewed at an average followup of 15 years (range, 10-21 years); of the remaining 41 patients, seven had a knee replacement, 18 had died, and 16 were lost to followup. The results, assessed according to the scor ing system of the Hospital for Special Surgery and including the seven patients who underwent a knee replacement, were excellent or good in 37 (55%) knees and fair or poor in 30 (45%). Twenty-six patients of th e current study previously were reviewed in 1986, with an average foll owup of 8 years, using the same clinical and radiographic criteria. In this group of 26 patients, excellent and good results decreased from 73% in 1986 to 46% in 1996. The knees in these 26 patients with a foll owup greater than 15 years had a statistically significant higher perc entage of fair and poor results. No statistically significant differen ces in the results were found according to the amount of correction. R adiographic controls at followup were available for 45 of the 60 knees ; a loss of correction greater than 5 degrees was observed in 11 knees . The results of this long-term followup study show that high tibial o steotomy for varus gonarthrosis allows a long period (range, 10-15 yea rs) of relief of pain, good range of motion, and function in a large n umber of patients. Results tend to deteriorate with time, particularly after 15 years.
