Fig. 2From: Jigless knotless internal brace versus other open Achilles tendon repairs using a progressive rehabilitation protocol: a biomechanical studyThe repaired Achilles tendon was anatomically oriented and fixed in a dynamic tensile-testing machine. The linear variable differential transformer (LVDT) (A) was used to measure the repair gap created during the cyclic loading test. The LVDT was welded with two pins (B) adjacent to the repair gap, which were used to fix the LVDT onto the specimenBack to article page
