ObjectiveTo investigate the preliminary clinical outcome of the femur RetroButton combined with glaze allogenic cortical press-fit bolt fixation in ACL reconstruction.MethodsA series of 10 patients suffered from ACL ruptures underwent standard procedures of arthroscopiic ACL reconstruction.The femoral tunnels were located and drilled through the anterior-medial approach，and the tibial tunnels were located and drilled through the incisions of harvesting grafts.For the femur graft fixation，glaze allergenic cortical press-fit bolt was inserted from the entrance in femoral tunnels joint after RetroButton fixation.For the tibia graft fixation，the absorbable interference screw was used which was strengthened by a portal-shape screw.The clinical outcomes were evaluated by x-ray，CT and ACL diagnosis test，including pivot and Lachman tests.ResultsResult of the pivot and Lachman tests of all patients showed to be negative at 3～6 months after surgery.Through X-ray and CT scan，we found that the femoral tunnel of the patients were not enlarged and part of the cortical press-fit bolt had been ab-sorbed.ConclusionThe combined femur graft fixation of RetroButton and glaze allergenic cortical press-fit bolt can effectively prevent the enlargement of the femoral tunnels at 3 to 6 months postoperatively.In addition，the glaze allergenic cortical press-fit bolt can promote the tendon-bone healing process because of the osteoinductive effects.15 refs，2 figs.
