The fixation strength of sutures is higher than these screw type devices?
Yes this is true; suture has been considered the gold standard for meniscal repair for many years. However there have been many reported problems with suture breakage, difficulty of knot tying and seating. This has been particularly prevalent due to the increased use of arthroscopic approaches for menisci repair.In vitro biomechanical pull-out test data indicates that the Inion TrinionTM Meniscus Screw provides equal initial strength to a single vertical 2-0 polydioxanone suture. Approximately 50 % and 30 % of the initial strength remains after 6 weeks and 12 weeks, respectively.Many suture based implants are non absorbable. Therefore both the implant and the suture remain permanently within the repair site. Should there be any wear particle debris generated then increased wear and damage to the articulating surfaces and/or possible arthrodesis of the joint may occur.With all suture based meniscal repair implants suture management is challenging and even more so if the surgeon is using
