Fresh osteochondral allografts for post-traumatic knee defects have been carried out at our institution since 1972. These grafts are performed for unipolar traumatic defects that involve a significant amount of both bone and cartilage in young patients who are not suitable candidates for prosthetic replacement. These grafts are done fresh within 24 hours of the death of the donor. If there is an associated deformity in the knee, then a realignment osteotomy is carried out through the femur if the deformity is valgus, and through the tibia if the deformity is varus. One hundred and twenty six knees in 123 patients were reconstructed with this procedure, with an average follow-up of 7.5 years. Survivorship analysis showed a 95% success rate at 5 years, 71% at 10 years, and 66% at 20 years. Copyright © 1997 by Freddie Fu, MD.
