The TIGHT-N™ Anchor is the next generation of tendon fixation intended to protect the tendon from wrap and laceration, to sit sub-cortically for high-strength fixation1, to leverage the benefits of an inlay technique, all in an implant designed for ease-of-use.

Current Challenges in Biceps Tenodesis

Interference Screw Failures

27% of patients experienced a popeye deformity with a screw after biceps tenodesis.2 This is believed to be secondary to interference screws cutting the tendon during insertion into the bone socket.3

Tendon Damage

In a biomechanical study, researchers observed that all the specimens in the interference screw group failed with tearing of the tendon at the bone-screw-tendon interface.4

Tendon Elongation

Studied suture anchor onlay techniques have shown statistically significant tendon elongation (10-27 mm on average) when compared to inlay interference screw techniques (4 mm on average).5

Features & Benefits

Protects Tendons and Grafts 

The half-sheath design is intended to cradle without compression and laceration from screw threads, and the technique uses a mallet to remove the risk of tendon wrap from rotating a screw into a bone tunnel.

Inlay Technique for Optimal Healing Environment 

The inlay technique provides exposure to blood and bone marrow and has been shown to provide a more optimal environment for healing than an onlay technique.

High-strength Fixation1 

With over 276N in tested pull-out force, the winged design allows the anchor to be securely seated under the cortical layer of the bone. 

Third-party Testing vs. Competition

High-strength Fixation1

When compared to competitive devices studied, TIGHT-N Anchor showed consistent high-strength fixation.

Less displacement* and variability compared to studied competitive devices1

Less displacement and variability gives you the confidence that your tendon is going to stay in place.**

The Suprapec Approach with TIGHT-N Anchor

Reduced Complication Rates 

Open biceps tenodesis using a subpec technique has shown a slightly greater complication rate in some studies,6  so with TIGHT-N Anchor we’re returning to the suprapec technique. 

Lower stress-riser fracture risk 

Subpectoral cortical drill holes for biceps tenodesis were shown to be a stress riser for fractures. In contrast, suprapectoral cortical drill holes were shown to create significantly less of a stress riser.7 

No difference in groove pain 

In recent studies, no significant difference was reported in bicipital groove pain among arthroscopic suprapectoral and open subpectoral approaches for biceps tenodesis.
