The new ligament was fixed to the tibia by a metallic screw and to the femur by a bioabsorbable screw. Griffith TB, et al. The two-stage group contained significantly more patients with meniscal and chondral pathology compared with the primary ACLR group. As this number has continued to increase, the incidence of revision ACL reconstruction (ACLR) has also grown to a rate of between 4.1 and 13.3% of all primary ACLRs performed [2].

ACL injuries most commonly occur during sports that involve sudden stops and changes in direction such as soccer, football, basketball and volleyball. The available data indicate that autograft for bone tunnel grafting in 2-stage ACL revision may be associated with a lower risk of revision ACL reconstruction graft failure compared with allograft bone. If no autograft is available for revision surgery, they advise augmentation of the allograft with the lateral extra-articular iliotibial band procedure to reduce the high failure rate associated with the use of the allograft. Hi you mentioned this was a staged procedure - any chance you can post the entire operative report without patient info?
