All-Arthroscopic Triangular Fibrocartilage Complex Ligamentoplasty: Technique and Results

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Arthroscopy

Background:

• Chronic triangular fibrocartilage complex (TFCC) injuries often lead to distal radioulnar joint (DRUJ) instability.
• Traditional surgical approaches may involve significant trauma and prolonged rehabilitation.

Purpose of the Study:

• To describe a modified all-arthroscopic technique for TFCC ligamentoplasty in chronic TFCC injuries with DRUJ instability.
• To evaluate the clinical and functional outcomes of this minimally invasive approach.

Main Methods:

• A prospective study involving 11 consecutive patients with chronic TFCC injury and DRUJ instability.
• All patients underwent a modified all-arthroscopic TFCC ligamentoplasty.
• Outcomes measured included joint motion, grip strength, pain (VAS), Mayo Wrist Score (MWS), and QuickDASH Score.

Main Results:

• The all-arthroscopic technique achieved 100% DRUJ stability at 12 months post-surgery.
• Significant improvements were observed in grip strength, pain reduction, and functional scores (MWS and QuickDASH).
• No major complications or reinterventions were reported in the study cohort.

Conclusions:

• The modified all-arthroscopic TFCC ligamentoplasty is a reliable and effective technique for irreparable peripheral TFCC tears.
• This minimally invasive approach reduces surgical trauma, potentially leading to decreased postoperative pain and faster rehabilitation.
• The technique demonstrates potential for improved reconstruction quality and superior functional outcomes in patients with DRUJ instability.
