How strong is the Teno Fix® compared to the current suture techniques?
The pullout force that obtained in the cadaver model is 45 Newtons. The unique capturing and compression of the collagen fibers of the tendon allow the device to use the high intrinsic strength of the tendon for a very strong repair. This allows for possible early active motion and the associated benefits. The 2-0 stainless steel suture has a >90 Newton tensile strength. The use of stainless steel eliminates the effects of gapping in the repair while the standard polypropylene suture repair which has a high elasticity rate, allowing stretching and gap formation. Gapping at the repair site of more than 2mm has been shown to reduce healing.
