How to Choose an Endobutton for ACL and PCL Reconstruction: Fixed Loop vs Adjustable Loop

Choosing an Endobutton for ACL or PCL reconstruction requires attention to the fixation design, loop configuration, material and graft requirements. An Endobutton is used with a graft to support fixation at the bone surface, but the correct product depends on the planned technique and the information provided in the manufacturer’s documentation. Well Trust offers Endo Button configurations that include fixed loop and adjustable loop options for sports medicine applications.

What Is an Endobutton?

An Endobutton is a small fixation button used with a suture loop or graft suspension system. The button is positioned in relation to the bone tunnel according to the surgical technique. The product page reviewed for this article identifies titanium as the material and lists the device under orthopedic surgical instruments. Because fixation requirements can vary between procedures, healthcare professionals should select the device based on the graft, tunnel dimensions, technique and applicable instructions for use.

Fixed Loop vs Adjustable Loop

Fixed loop Endobutton

A fixed loop Endobutton uses a preset loop length. This configuration can be considered when the required loop length has been established during surgical planning. The Well Trust product information lists fixed loop specifications of 15, 20, 25, 30 and 35 mm. A fixed option may help simplify ordering when the required dimensions are known, but the selected size still needs to match the procedure and graft configuration.

Adjustable loop Endobutton

An adjustable loop Endobutton is designed for loop adjustment during graft positioning. This configuration can provide flexibility when the final graft position or tunnel relationship requires intraoperative adjustment. The Well Trust product information identifies an adjustable loop configuration with 2/8 holes. The adjustable loop should be selected and handled according to the product instructions and the technique used by the qualified surgical team.

How to Select the Right Loop Configuration

Start by confirming the procedure and the intended fixation position. Then review the graft length, tunnel dimensions, desired loop arrangement and available implant configuration. A fixed loop may be considered when the required length is clearly defined. An adjustable loop may be considered when the surgical plan requires adjustment during positioning. These descriptions are product-selection principles, not a substitute for clinical judgment or professional training.
