Tibialis Anterior Tendon Reconstruction Using Augmented Half-Thickness Tendon Segment Transposition

Area of Science:

• Orthopedic Surgery
• Musculoskeletal Research

Background:

• Tibialis anterior tendon rupture leads to significant patient morbidity.
• Existing reconstruction techniques have limitations.

Purpose of the Study:

• To describe the outcomes of a novel surgical technique for tibialis anterior tendon reconstruction.
• To evaluate the efficacy of augmented, half-thickness tibialis anterior tendon segment transposition.

Main Methods:

• Retrospective review of 3 patients with surgically treated attritional distal tibialis anterior tendon rupture.
• Novel technique involved distal transposition of a healthy tendon segment augmented with human acellular dermal matrix allograft.
• 1-year follow-up assessed range of motion, motor power, pain, and functional scores.

Main Results:

• All patients achieved symmetrical range of motion and motor power, with the ability to heel walk.
• Mean pain scores significantly improved postoperatively.
• Mean Foot and Ankle Ability Measure scores showed substantial improvement.
• No postoperative complications were reported.

Conclusions:

• Augmented, half-thickness tibialis anterior tendon segment transposition appears to be a safe and effective technique for reconstructing distal ruptures.
• Short-term clinical outcomes are comparable to other established reconstruction methods.
• Further research with larger cohorts is warranted to confirm these findings.
