There are an estimated , ACL repairs in the US each year: most ACL tears occurs from noncontact injuries. The % of the knee ligament injuries. Among femoral cortical suspension devices, the EndoButton CL . to confirm the position of the EndoButton after ACL reconstruction (Fig 3). One device used for femoral fixation of ACL grafts is the EndoButton Continuous Loop (Smith & Nephew. Endoscopy, Andover, Mass). This device has been well.

The effect of cortical button location on its post-operative migration in anatomical double-bundle anterior cruciate ligament reconstruction.
The EndoButton revealed a smaller standard deviation of ultimate failure load and yield load. Caution is need when removing the soft tissue over the lateral aspect of the femoral cortex.
Journal of Orthopaedic Research. EndoButton is an extra-articular device made of metallic button and a polyurethane ribbon Endotape.
The Bio Cross-Pin broke in all cases tested. The sum of these factors may increase the graft micromovement and delay graft healing Fu et al. In two cases, the button pulled out the bone tunel with visible plastic deformation.
As a result, the button pulled out from the cortical bone Ahmad et al. No significant difference of ultimate failure load, yield load, and energy was observed between the Bio Cross-Pin and EndoButton fixation. Knee Surg Sports Traumatol Arthrosc. The previous studies showed a positive correlation between a malpositioned EndoButton and a higher rate of button migration.
We believe this arthroscopic reduction technique could be beneficial in the case of a migrated EndoButton during ACL reconstruction of the knee; however, studies on long-term clinical outcomes with a larger cohort will be necessary to determine its efficacy.
Intra-articular detachment of the Endobutton more than 18 months after anterior cruciate ligament reconstruction. A standard arthroscopic examination is performed through anteromedial and anterolateral portals. There is a paucity of available literature regarding how to best remove interposed soft tissue and reduce the position of the EndoButton.
Biomechanical properties of quadruple tendon and patellar tendon femoral fixation techniques. National Center for Biotechnology InformationU. Weight-bearing exercise as tolerated with crutches is also initiated immediately. Table 1 shows the results of single-cyclic load-to-failure test.
Femoral fixation solution for ACL reconstruction | Smith & Nephew – Corporate
In vitro comparison between cortical and cortico-cancellous femoral suspension devices for anterior cruciate ligament reconstruction: The probability level was set at 0. A edobutton stiffness can, therefore, increase the displacement associated with anterior translation and may result in an unstable knee.
Received Mar 31; Accepted Jul The endobbutton band endoscopic portal for direct visualization of ideal button placement. Report of two cases. Do adjustable loops lengthen? A systematic review of randomized controlled trials. The specimens were kept moistened by spraying with physiological solution 0.
Yasuo OhnishiM. Mechanical comparison of biodegradable femoral fixation devices for hamstring tendon graft – A biomechanical study in a porcine model.
Over the top or endobutton for ACL reconstruction?
Journal of Orthopaedic Science. Abstract Suture button—based femoral cortical suspension constructs of anterior cruciate ligament grafts can facilitate a fast and secure fixation.
A poor fixation can lead to graft slippage endobufton result in knee instability or failure of fixation Fu et al. Both techniques are able to support the immediate post-operative loading applied. Displacement at failure mm.
ACL reconstruction suture button – ENDOBUTTON – Smith & Nephew
If soft tissue is interposed between the EndoButton and lateral aspect of the femoral cortex, a radiofrequency RF probe Vulcan is inserted through another LF portal to remove the soft tissue. Migration of EndoButton after anatomic double-bundle anterior cruciate ligament reconstruction. Services on Demand Journal. Our arthroscopic reduction technique allows the surgeon to assess for malpositioning and migration of the EndoButton directly through the LF portal and remove any soft tissue interposed between the EndoButton and the lateral cortex of the femur.
Immediately after the graft fixation, each femur was clamped to a custom device with bone cement PMMA and screws. Second-generation, no-incision anterior cruciate ligament reconstruction. Each femur was dissected and the superficial flexor tendon with approximately 5 mm diameter was extracted and used as a double graft.
The second aspect to be noted is the direction of bone tunnel axis during graft tension testing.
The force x displacement curves was used to calculate these variables because we are not focusing the graft strain but the mechanical behavior of the whole system bone-graft-implant. Introduce a shaver through another LF portal to clean up the soft tissue around the EndoButton. An arthroscope is inserted into the LF portal to evaluate for EndoButton migration from the endobuttoon aspect of the femoral cortex Fig 2 A and B. Each specimen was then submitted to cyclic and single-cyclic loading-to-failure test.
