Biomechanic Comparison of the Teno Fix Tendon Repair Device With the Cruciate and Modified Kessler Techniques

The Teno Fix repair system did not confer a mechanical advantage over the locked cruciate or modified Kessler suture techniques for zone II lacerations in cadaveric flexor tendons during cyclic loading in a linear testing model. This information may help to define safe boundaries for postoperative rehabilitation when using this internal tendon repair device.
