384 Use of A Dry Swab During ACL Hamstring Tendon Graft Preparation May Lead to Decreased Graft Diameter at Implantation with Subsequent Rebound in Graft Diameter When Exposed to Haemarthrosis – A Porcine Tendon Study

Abstract Introduction ACL reconstruction surgery commonly utilises a hamstring tendon graft. Grafts are normally covered with wet swab prior to implantation. The aim of this study was determine the variance in graft diameter when comparing traditional dry swab. Method Flexor tendons from selection fresh pig trotters were isolated and prepared standard preparation technique. Half grafts swab; other half Graft diameters measured at 10-minute intervals. After 30 minutes submerged Hartmann’s solution simulate post-operative haemarthrosis, checked again after 1 hour solution. Results Use resulted 0.5mm greater reduction than group. group also showed an increase by soaked solution, not seen Conclusions Using produces smaller diameter, would allow bone tunnels, retaining stock. subsequent rebound may press fit mechanism facilitate improved integration into tunnel.
