Abstract
We reviewed 32 deep-frozen irradiated allografts used for the reconstruction of bone defects in 20 knees. They were subdivided into bulk grafts, cortical strut grafts, and morsellised bone. The average follow-up was 4.2 years (2 to 7.2). Radiographs showed union of the allograft to the host in all cases. Two allografts later fractured and three knees required further surgery because of infection. The allografts effectively filled large bone defects around the knee, lessening the need for custom-made and constrained prostheses.
