Suspensory Fixation Device for Use With Bone-Patellar Tendon-Bone Grafts

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering

Background:

• Bone-patellar tendon-bone (BTB) grafts are effective for anterior cruciate ligament (ACL) reconstruction.
• Traditional screw fixation methods have drawbacks, including tunnel blowout and graft damage.

Purpose of the Study:

• To describe and evaluate a novel suspensory fixation technique for BTB ACL reconstruction.
• To highlight the advantages of adjustable-loop suspensory fixation over traditional screw fixation.

Main Methods:

• A technique using Pullup BTB adjustable-loop length suspensory fixation for both femoral and tibial sides is described.
• The graft is harvested and prepared using standard procedures.
• The suspensory fixation device allows double passage of the loop through each bone block for added security.

Main Results:

• The suspensory fixation technique offers precise tunnel positioning and high tensile strength.
• Adjustable loops provide control over bone block placement and allow for graft retightening.
• The double-loop passage enhances safety during the anterior cruciate ligament reconstruction procedure.

Conclusions:

• Adjustable-loop suspensory fixation is a secure and effective option for BTB ACL reconstruction.
• This technique potentially offers an improved alternative to traditional screw fixation methods.
• It facilitates anatomic reconstruction with enhanced graft security and positioning control.
