Beyond Wires: Why Auxein’s AV-Wiselock Anterior Patella Plate Redefines Fixation Standards

September 5, 2025

Introduction

For decades, Tension Band Wiring (TBW) has been the gold standard for patella fracture fixation. While effective in basic fracture patterns, its limitations are well documented: implant migration, poor biomechanical stability, frequent need for revision, and delayed recovery.
A new era in fixation has emerged with Anterior Patella Plating Systems, particularly the Auxein 2.7mm AV-Wiselock Anterior Patella Plates. Supported by robust biomechanical and clinical evidence, plating is rapidly becoming the superior alternative.

Clinical Evidence: Plating vs TBW

Complication Rates
TBW/CCW: up to 40% postoperative complications
Plating: as low as 8.7%
(Müller et al., 2024)

Biomechanical Stability

TBW often fails under cyclic loading, leading to displacement and instability.
Locked anterior plating shows minimal interfragmentary rotation (0.09° vs 0.73° for TBW) and higher resistance to mechanical failure.
(Athar et al., 2024)

Revision Surgery

TBW: revision rates up to 17.5% due to migration, breakage, and skin perforation.
Plating: 0% revision rates reported in comparative studies.
(Stoffel et al., 2023)

The AV-Wiselock Advantage

The Auxein 2.7mm AV-Wiselock Anterior Patella Plate is engineered to address TBW’s shortcomings and align with evidence-based best practices.
Key Innovations:

Variable-Angle Locking Technology (±15°)
Low-Profile Anatomical Design
Bendable & Cuttable Construction
Titanium Alloy Build
Suture Windows for Reinforced Fixation

AV-Wiselock Plate vs. TBW: A Comparative Advantage

Feature	Tension Band Wiring (TBW)	AV-Wiselock Anterior Patella Plate
Biomechanical Stability	Limited under cyclic loading	Superior under dynamic stress
Implant Migration Risk	High	Minimal
Soft Tissue Irritation	Frequent	Low-profile design reduces risk
Fracture Versatility	Transverse and displaced fractures	Simple, wedge, & comminuted fractures
Recovery	Slower, delayed mobilization (8-10 Weeks)	Early mobilization possible (2-3 Weeks)

Clinical Impact: Faster, Safer Recovery

By combining superior biomechanical stability, lower complication rates, and elimination of revision risk, the AV-Wiselock Plate enables:

Early mobilization
Reduced stiffness
Better long-term functional outcomes

As highlighted in the systematic review by Theodoulidis et al., 2023, plating is not only a safe alternative but increasingly the preferred approach in both simple and complex patella fractures.

Conclusion

The evidence is decisive: anterior patella plating is surpassing TBW as the new standard in fracture fixation. With innovations like the Auxein AV-Wiselock Anterior Patella Plate, surgeons can deliver stronger fixation, earlier recovery, and better patient satisfaction—redefining outcomes in patella trauma care.
