Lateral Extra-Articular Tenodesis (LET) has regained prominence as a crucial complement to Anterior Cruciate Ligament Reconstruction (ACLR), enhancing rotational stability and reducing the rate of graft failure. Integrating biomechanical innovation with clinical research, Auxein continues to redefine fixation strategies for optimal surgical outcomes.
Auxein’s design philosophy merges biomechanical integrity with surgical efficiency. Our anchor systems, fixation devices, and graft management solutions ensure consistent performance and long-term joint stability. By aligning engineering innovation with clinical need, Auxein enables surgeons to restore mobility with confidence.
LET enhances rotational control by resisting excessive tibial internal rotation and anterior translation. Combined with ACLR, it decreases graft strain by approximately 50% (Guenther et al., JBJS, 2017), ensuring a balanced load-sharing mechanism. Studies consistently show that the dual approach reduces pivot shift phenomena and lowers graft rupture rates.
| Study (Year) | Procedure | Failure Rate | Pivot Shift Reduction | Patient Satisfaction |
| Rowan et al., 2019 | ACLR + LET | ↓3.8% | ↓45% | 92% |
| Perelli et al., 2023 | Isolated LET | N/A | Moderate | 85% |
| Minguell et al., 2023 | Revision ACLR + LET | ↓5–10% | Strong | 89% |
| Zanna et al., 2023 | ACLR + LET | ↓35% | ↓60% | 94% |
| Condello et al., 2019 | Allograft ACLR + LET | ↓40% strain | ↓48% | 90% |
Indication | Rationale | Preferred Technique |
High-grade pivot shift | Restores anterolateral restraint | Modified Lemaire LET |
Revision ACLR | Reduces re-rupture risk | Modified MacIntosh |
Generalized laxity | Controls tibial internal rotation | Iliotibial Band LET |
High-demand athletes | Prevents graft overload | Hamstring + LET |
Lateral Extra-Articular Tenodesis combined with ACL Reconstruction represents the next step in restoring native knee biomechanics. By reducing rotational laxity and enhancing joint stability, this dual reconstruction ensures longevity and performance. Through continued innovation, simulation, and clinical partnership, Auxein is shaping the future of orthopedic biomechanics.
