In a similar study, Roche et al. (2005) investigated the ultimate tensile strength of low dose gamma irradiation (15.4-15.5 kGy) on patellar ligaments and fascia lata allografts. Each irradiated allograft was matched with a control non-irradiated graft from the same donor to limit biomechanical variability resulting from different donors. The study did not find a statistical difference in the tensile strength between the matched low dose irradiated and non-irradiated allografts. In addition, Gibbons et al. (1991) showed in a biomechanical study that maximum stress, maximum strain, and strain energy density to maximum stress was not significantly reduced in goat BPTB grafts irradiated with 20 kGy of gamma irradiation. Further, Goertzen et al. (1995) found no significant difference in strength between canine BPTB grafts irradiated with 25 kGy and non-irradiated BTPB grafts after being implanted in an ACL reconstruction for (Haut and Powlison 1990; Mae et al. 2003; Maeda et al. 1993 Maeda et al. , 1998 Smith et al. 1996) of irradiated tendons indicate that treatment below 20-25 kGy have minimal impact on biomechanical properties.
