Behaviour of bone allografts in the advancement of the tibial tuberosity.
In order to determine the behaviour of bone allografts in the advancement of the tibial tuberosity, we studied retrospectively 134 knees belonging to 119 recipients of frozen bone allograft for the treatment of a symptomatic patellofemoral osteoarthrosis. All patients had a 1.2-1.5 cm tibial tuberosity advancement with a release of the lateral patellar retinacula and no other additional surgery. Total incorporation of grafts took place in 116 cases (86.6%); graft resorption appeared in 16 patients (11.9%)(total resorption 3, and partial resorption 13). No disease transmission has been detected. To avoid donor site morbidity associated with harvesting iliac crest, the use of frozen bone allograft is a good alternative in the advancement of the tibial tuberosity.
