The Gore-Tex ligament is a permanent prosthesis of polytetrafluoroethylene (PTFE) and has an ultimate tensile strength of 5,300 Newtons. The technique was originally designed for salvaging knees that had already failed anterior cruciate ligament (ACL) reconstructions. The technique allows for immediate full weight bearing and full range of motion without a cast or bracing.Over 1,000 Gore-Tex ACL reconstructions have been performed in the United States. The Southern California Orthopedic and Sports Medical Group has performed 103 Gore-Tex ACL reconstructions arthroscopically without extraarticular backup procedures.
