Resumen (ES)
Scintigraphic studies were performed in 20 patients with cemented total prosthesis of the knee. The patellar release was necessary in 10 cases. None of the patients developed knee extension deficits. Scintigraphic studies were performed 12 months after surgery in order to know the patellar blood supply at that moment. Patellar isotopic uptake was compared with the uptake at the distal metaphysis of the homolateral femur, at lateral projection. We haven''t found any differences between both groups, so we consider that the patellar release doesn''t make a less blood supply twelve months after surgery.
