The cases of twenty-four patients who had twenty-six osteotomies of the
tibial tubercle in conjunction with total knee replacement were analyzed
with regard to complications and technical considerations. The patients
were followed for a minimum of two years (average, three years and six
months). Major complications related to the surgical technique occurred in
23 per cent of the knees and complications not related to the technique, in
an additional 8 per cent. Rheumatoid arthritis and a history of at least
one previous operation about the knee were predisposing factors for these
complications.
