Die Versorgung der frischen und der veralteten Kreuzbandruptur mit kombiniertem autologem und alloplastisch verstärktem Sehnentransplantat (Polypropylen-Band)

Abstract

After discussing basic problems in repair and reconstruction of acute as well as secondary anterior cruciate ligament-lesions authors present a modified Kennedy-MacIntosh technique of acl-reconstruction. Temporary compensation of loss in tensile strength of the autograft (quadriceps-patellar-tendon) is achieved by an 8 mm Polypropylene band with excellent biocompatibility and mechanical characteristics. "Biological fixation" of the distal part of the tendon-graft avoids "stress shielding" and physiological applied stress may lead to remodeling and structuring in the sense of functional adaptation. Acute acl-ruptures are sutured or reinserted and treated with fibrine-tissue-glue. Furthermore a semitendinosus-autograft combined with a 6 mm Polypropylene band is added. Details of the operations-procedure are presented as well as steps in postoperative treatment. Early results and complications are finally discussed.

Augmented repair and early mobilization of acute anterior cruciate ligament injuries

“…The use of autologous material (semitendinosus, gracilis, or patellar tendon) requires that a large portion of the cruciate fibers must be sacrificed because of the relatively large diameter of these grafts. 5,57 In this study we found only one patient with a foreign body reaction, demonstrating good tolerance for the Trevira augmentation device. In contrast to other synthetic ligaments that fray upon rupture, the Trevira augmentation device develops a clean break without evidence of abrasion.…”
