“…These findings are similar to those of Forward and Cowan and Rodeo et al [16,35]. Forward and Cowan [16] used the long digital flexor tendon of rabbits and placed it in a tunnel in the calcaneus. Rodeo et al [35] used the long digital extensor tendon of dogs and placed it in a tibial tunnel.…”

In an attempt to assess reconstruction of the anterior cruciate ligament (ACL) by a new method, 18 New Zealand white rabbits underwent ACL replacement using the medial one-third of the patellar tendon and the semitendinosus tendon, thus partly reproducing the anatomical configuration of the ACL, with the semitendinosus tendon replacing the posterolateral bundle of the ACL and the patellar tendon replacing the anteromedial bundle. The Noulis-Trillat-Lachman test was performed before and after transection of the ACL, after reconstruction and before sacrifice. The animals were divided into four groups and were killed at 3, 6, 12 and 22 weeks after surgery. Femur-ligament-tibia complexes were evaluated postoperatively for gross morphology and histological appearance. The tendons of the first group showed compact parallel fibres with no definitive separation of their bundles and areas of disorganized collagen matrix. Tendons were surrounded by trabecular lamellar bone haphazardly arranged. The tendons of the second, third and fourth groups looked more like normal tendon. The trabecular bone surrounding the tendons formed a tunnel. The Noulis-Trillat-Lachman test result was negative before the procedure, 6.5 +/- 0.5 mm on average after transection of the ACL, 1.5 +/- 0.6 mm after the procedure, and negative again before sacrifice. The joints of the animals killed at 12 and 22 weeks showed signs of osteoarthritic lesions.

“…In our study (case 1), osseointegration took place without an interference screw, and it seems that so long as the tunnel diameter corresponds to the graft, this is possible without fixation with an interference screw. These findings are also in line with animal studies in which tendons became integrated with the surrounding bone in predrilled holes (Kernwein 1942, Whiston and Walmsley 1960, Forward et al 1963, Rodeo et al 1993, St Pierre et al 1995, Liu et al 1997. Another difference between our findings and those of Pinczewski et al (1997) is the histological appearance of the tendon in the tunnel.…”

“…Healing of ruptured tendons occurs in three biological phases: the cellular reaction phase, the fibrous protein synthesis phase, and the remodeling phase. In healing tendons, it has been observed that stiffness of the tissue returns before strength and that the healing of mid‐tendon injuries parallels the healing of bony‐insertion‐site injuries with respect to tensile strength 8,9 . Much of what is known about tendon healing has been gained from animal studies involving surgically transected and repaired tendons 10–19 .…”

Biochemical, biomechanical and ultrastructural properties of the connective tissue matrix were investigated during the early remodeling phase of tissue repair in experimentally tenotomized and repaired rabbit Achilles tendons. Sterile surgical tenotomy was performed on the right Achilles tendons of 14 rabbits and allowed to heal for 15 days. The animals were euthanized and the Achilles tendons excised from both limbs. The left contralateral Achilles tendon of each rabbit was used as a control in the experiments. Prior to biochemical analysis, both intact and healing tendons were tested for their biomechanical integrity. The results revealed that the healing tendons had regained some of their physicochemical characteristics, but differed significantly from the intact left tendons. The healing tendons regained 48% tensile strength, 30% energy absorption, 20% tensile stress, and 14% Young's modulus of elasticity of intact tendons. In contrast, biochemical analysis showed that the healing tendons had 80% of the collagen and 60% of the collagen crosslinks (hydroxypyridinium) of normal tendons. Sequential extraction of collagen from the tissues yielded more soluble collagen in the healing tendons than intact tendons, suggesting either an increase in collagen synthesis and/or enhanced resorption of mature collagen in healing tendons compared to intact tendons. Electron microscopic studies revealed remarkable differences in the ultrastructure between intact and healing tendons. These observations could explain, in part, the connective tissue response to healing during the early phases of tissue remodeling.
