Abstract
Systems and methods for preparing a ligament graft for a ligament reconstruction procedure are provided. In general, the described techniques utilize a graft preparation system having a holder and a delivery suture assembly removably coupled thereto. The delivery suture assembly can include a spine coupled with an anchor suture configured to form a self-tightening knot used to position the assembly around a graft and a plurality of suture windings configured to be affixed to the graft when the assembly is deployed. The assembly is delivered to the graft using the holder and the sutures can be affixed to the graft without penetrating therethrough. The spine helps to evenly distribute the load among the windings compressing the graft which are thus are capable of withstanding increased loads. Thus, an improved, simplified, and time- and labor-saving approach to preparing ligament grafts is provided.
