The Effects of Freezing on the Tensile Properties of Repaired Porcine Flexor Tendon

Effects of Tension Across the Tendon Repair Site on Tendon Gap and Ultimate Strength

“…[15][16][17][18] The flexor digitorum profundus tendons were cut transversely at the level of the metatarsophalangeal joint after exposing them through an incision in the flexor sheath. This level corresponds to the middle part of human zone 2 flexor tendons structurally.…”

Viscoelastic Relaxation and Recovery of Tendon

“…Investigators report that such careful freezing procedures have little effect on the biomechanical properties of collagenous tissues such as tendon and ligament. 14,22 All experiments were performed using a servohydraulic mechanical test system (Bionix 858; MTS, Minneapolis, MN) in conjunction with a computer to collect data. The load frame was equipped with a lower block designed to hold the potted bone and an upper soft tissue grip designed to hold the tendon.…”

Effects of gamma irradiation and repetitive freeze–thaw cycles on the biomechanical properties of human flexor digitorum superficialis tendons

“…However, as the processing for biomechanical evaluation is becoming more complex and time-consuming, specimens may need additional periods of frozen storage before the experiment is completed. Although previous studies have reported that one period of deep freeze storage or o2 cycles of freeze-thaw on soft tissue have relatively little effect on the biomechanical properties of ligaments and tendons (Hirpara et al,2008;Lee et al, 2009;Moon et al, 2006b), it is uncertain if repetitive freeze-thaw cycles will significantly affect these properties. Therefore, the purpose of this study was to evaluate the biomechanical properties of human tendons after gamma radiation and repeated freeze-thaw cycles, and to compare them with fresh specimens.…”
