BiPOD Arthroscopic Acromioclavicular Repair Restores Bidirectional Stability

Area of Science:

• Orthopedics
• Sports Medicine
• Surgical Techniques

Background:

• Acromioclavicular (AC) joint stabilization is complex, with current methods often failing to provide reliable vertical and horizontal plane stability.
• High-grade AC joint injuries require robust surgical repair to restore joint function and prevent long-term complications.

Purpose of the Study:

• To evaluate the efficacy of the BiPOD (bidirectional) repair technique in achieving stable reconstruction of the AC joint.
• To assess the BiPOD technique's ability to provide both vertical and horizontal stability following acute, high-grade AC joint injuries.

Main Methods:

• Prospective review of the first 6 patients undergoing the arthroscopically assisted BiPOD repair for acute high-grade AC joint injuries.
• Image intensifier guidance was used for the reconstruction of both coracoclavicular and AC ligaments.
• Repair utilized a combination of FiberTape and Poly-Tape for rigid fixation, with radiographic analysis (coracoclavicular distance and Alexander axillary view) at 6-month follow-up.

Main Results:

• A single patient experienced a superficial infection; no other complications were reported.
• Preoperative coracoclavicular distance difference of 9±2 mm was reduced to 0.3±2 mm at 6 months, indicating successful vertical reduction.
• All 6 patients demonstrated stable horizontal reduction on the Alexander axillary view, with the clavicle aligned with the acromion.

Conclusions:

• The BiPOD acromioclavicular reconstruction technique effectively restores bidirectional stability to the AC joint.
• This arthroscopic approach provides a reliable method for managing high-grade acute AC joint injuries, with positive early radiographic outcomes.
