Graft creep
WebJun 1, 1996 · Viscoelastic creep is a well-know phenomenon associated with collagenous soft tissues under sustained tensile load. Despite our understanding of this phenomenon and the potential for “loosening” of the graft over time, pretensioning of bone—patellar tendon—bone (B-PT-B) grafts for reconstruction of the anterior cruciate ligament (ACL) … WebMar 16, 2004 · A series of graft creep tests under cyclic loads was also done. The results showed that there was no significant difference in graft construct elongation under cyclic loads (range 0.7–1.3 mm) after allowing for 0.4 mm mean graft creep. The WasherLoc gave the highest ultimate strength (945 N, p <0.001, range 490–945 N). We concluded that all ...

The graft was sutured in place by means of interrupted sutures (5-0 polyglycolic acid sutures) at the coronal and apical corners. A basting-type of suture was also used, to obtain good adaptation of the graft to the recipient site. A conventional autogenous gingival graft (approximately 1 mm thick) was placed ...
