The Attachable Button is a modular two-piece fixation system designed to solve the challenges of narrow bone tunnels in minimally invasive joint surgery. Unlike traditional pre-assembled buttons, the Attachable Button System (ABS) allows the surgeon to shuttle the suture loop through a small-diameter tunnel (as small as 3.5mm) before attaching a larger titanium button on the cortical surface. Manufactured from medical-grade Titanium Alloy (Ti-6Al-4V), the button features specialized slots that securely lock onto the graft loop. This modularity allows for the use of larger-diameter buttons (11mm to 20mm) to maximize the "footprint" on the bone, which is essential for patients with soft or osteoporotic bone. Optimized for ACL, PCL, and Tibial fixation, the TOOLMED Attachable Button ensures a secure seal of the tunnel while providing the highest level of pull-out strength.

Product Description
By keeping the button separate during the initial passing stage, surgeons can use smaller bone tunnels, preserving more of the patient's natural bone stock without sacrificing fixation strength.
The system allows surgeons to choose the button size intraoperatively. If the bone cortex appears weak or the tunnel opening is slightly enlarged, a larger 20mm button can be attached for increased security.
The "ABS" design provides a broader footprint than standard buttons, distributing the graft load more evenly across the cortical surface to prevent button migration or bone erosion.
Used in complex Coracoclavicular (CC) ligament repairs and pectoral tendon reattachments where a small passing tunnel is required but a large cortical footprint is needed for stabilization.
Ideal for labral reconstruction and gluteus medius repairs that require high-strength, low-profile suspensory fixation in the pelvic or femoral bone.
Primarily used for tibial fixation in "all-inside" ACL and PCL reconstructions. It is also highly effective for ankle syndesmosis repairs where cortical bridge strength is a concern.

The Attachable Button is a two-part surgical anchor. It allows a surgeon to pull a strong suture loop through a very thin hole in the bone first. Once the loop pops out on the other side, the surgeon "attaches" a larger metal button to it. It’s like putting a large washer on a bolt after the bolt is already through the wall.
This system is a favorite for Tibial Fixation in ACL Reconstruction. Because the tibia (shin bone) often has a softer cortex than the femur, surgeons like to use the Attachable Button to provide a larger surface area for the fixation to hold onto, ensuring the new ligament doesn't pull through the bone.
The primary advantage is Flexibility. Surgeons don't have to commit to a button size until they see the quality of the bone. It also makes the surgery easier because passing just a thread through a narrow bone tunnel is much simpler and faster than trying to squeeze a pre-attached metal button through the same space.
The biomechanics of the ABS system focus on Load Distribution. By using a larger button (e.g., 20mm), the force ($F$) applied by the ligament graft is spread over a larger area ($A$), significantly reducing the stress ($S = F/A$) on the bone. This prevents the "windshield wiper effect" and ensures the button stays flush against the cortex during the entire healing period.
First, a small 3.5mm pilot hole is drilled. The suture loop is shuttled through the tunnel using a passing wire. Once the loop exits the skin, the Attachable Button is slid onto the loop through its precision-machined slots. The surgeon then pulls the graft back into the tunnel, seating the button firmly against the bone. Final tensioning is completed by pulling the adjustment sutures.
Since the button is made of medical-grade titanium, it is permanent and MRI-safe. Patients usually follow a standard rehabilitation protocol for ACL or ligament repair. The broad contact area of the Attachable Button provides excellent early stability, which is crucial for the first 6–12 weeks when the graft is biologically incorporating into the bone.
The Attachable Button represents a significant advancement in modular fixation. By allowing for larger cortical footprints through smaller tunnels, it gives surgeons a safer, more reliable way to secure ligament grafts in patients with varying bone densities.
No. Once the graft is tensioned, the pressure of the loop against the button slots creates a secure mechanical lock. It cannot be detached without surgically releasing the tension.
No, the button is designed with "side-loading" slots that allow the surgeon to click the loop into place in seconds, even with surgical gloves on.
A 20mm button is usually chosen for "revision" surgeries (where a previous hole exists) or for patients with lower bone density, as it provides more surface area to prevent the button from sinking into the bone.
Yes. The Attachable Button System works perfectly with hamstring tendons, quadriceps tendons, and even synthetic grafts.
Yes. The titanium button is "radiopaque," meaning it will show up clearly on an X-ray so your doctor can verify that it is sitting perfectly against the bone.
