B Anteroposterior eneobutton of a right Rt knee showing reduced position of migrated EndoButtons after arthroscopic reduction. Footnotes The authors report the following potential conflict of interest or source of funding: In general, suspension of the EndoButton over soft tissue, such as the ITB, was weaker than that on the femoral cortex.
The advantages of this arthroscopic technique include small incisions and direct visualization that can help remove rndobutton soft-tissue interposition and reduce a migrated EndoButton. The previous studies showed a positive correlation between a malpositioned EndoButton and a higher rate of button migration. Make an LF portal by longitudinally extending the guide pin incision.
This technique requires careful cleaning of the soft tissue over the lateral cortex of the femur. Fortunately, the patient had no ACL instability. Second-generation, no-incision anterior cruciate ligament reconstruction. The techniques allows direct visualization of the reduction of the migrated EndoButton. Suture button—based femoral cortical suspension fixation of anterior cruciate ligament ACL grafts can facilitate a fast and secure graft fixation for ACL reconstruction.
An unidentified pitfall of Endobutton use: A systematic review of randomized controlled trials. Associated Data Supplementary Tchnique Video 1 After passage of the anterior cruciate ligament Surgiical graft through the tibial tunnel, the position of the EndoButton is confirmed by fluoroscopy after the EndoButton is felt to be flipped in a right knee. Caution is need when removing the soft tissue over the lateral aspect of the femoral cortex. Care is taken to ensure that the femoral and tibial tunnels are created anatomically in every patient.
Suture button—based femoral cortical suspension constructs of anterior cruciate ligament grafts can facilitate a fast and secure fixation.
Etchnique surgical techniques do not allow adequate visualization of the button in its final position to confirm that it is correctly flipped over without soft-tissue interposition between the EndoButton and the iliotibial band ITB or vastus lateralis. In addition, there is a small possibility of injury to the lateral superior genicular artery. D Removed soft tissue beneath migrated EndoButton arrow. Femoral suspension devices for anterior cruciate ligament reconstruction: Our technique cannot be applied in the case of a migrated EndoButton resulting from malpositioning of the endobuttin bone tunnel.
However, arthroscopic ACL reconstruction is more technically complex, and inexperienced surgeons may have difficulty identifying the interposed soft tissue and EndoButton.
Articles from Arthroscopy Techniques are provided here courtesy of Elsevier. Clinical and functional outcomes after anterior cruciate ligament reconstruction using cortical button fixation versus transfemoral suspensory fixation: Switch the shaver to a Vulcan probe to remove any interposed soft tissue beneath the EndoButton.
Postoperative clinical examination before revision showed range of motion without increased resistance. They determined that migration of the EndoButton was more common with the presence of soft-tissue interposition and clinical outcomes were unaffected by migration and soft-tissue interposition.
In the case in which the EndoButton migrates from the lateral aspect of the femoral cortex Fig 1 Aa lateral femoral LF portal is created through the femoral guide pin incision on the lateral aspect of the femur.
Report of two cases. There is also a risk of damage to the EndoButton loop by using the Vulcan. A Vulcan probe can also be inserted through the same portal to help manipulate and fit tecunique EndoButton into the proper position at the lateral cortex of the femur by pulling the graft on the tibial side Fig 2 D and E. Yasuo OhnishiM.
Find articles by Hajime Utsunomiya. Postoperative anteroposterior radiograph of a right Rt knee showing reduced EndoButton to lateral aspect of femoral cortex. Weakening of femoral fixation before graft integration might cause loosening of the reconstructed ACL and failure of the ACL reconstruction.
National Center for Biotechnology InformationU. There appears to be a short recovery time, which is especially beneficial for athletes who must quickly recover back to their preinjury activity level. Physical therapy, consisting of exercise without resistance, to improve range of motion is initiated immediately after surgery.

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. A standardized postoperative protocol is implemented for each patient.
C The Vulcan probe arrowheadintroduced through the second LF portal, can remove the interposed soft tissue surrounding ebdobutton EndoButton arrow. Pediatric techniquf cruciate ligament femoral fixation: Reduce the migrated EndoButton to the proper position, and fit the EndoButton to the lateral cortex of the knee by pulling the graft on the tibial side.
Introduce a shaver through another LF portal to clean up the soft tissue around the EndoButton. Published online Oct This Technical Note describes an arthroscopic technique to prevent migration of the EndoButton using a femoral guide endobuttoh incision on the lateral aspect of the femur as an endoscopic portal. This Technical Note presents an arthroscopic technique that successfully removes interposed soft tissue between the EndoButton and the lateral aspect of the femoral cortex and reduces EndoButton migration from the lateral aspect of the femoral cortex of the knee.
Several techniques have been proposed to ensure accurate placement of the EndoButton and lessen the probability of malpositioning. Intra-articular detachment of the Endobutton endobuttn than 18 months after anterior cruciate ligament reconstruction.

Migration of EndoButton after anatomic double-bundle anterior cruciate ligament reconstruction. Our arthroscopic reduction technique endobutyon 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 techbique femur.
A probe can be inserted through the same portal to help manipulate the EndoButton into the proper position at the lateral cortex of the femur by pulling the graft on the tibial side. Am J Sports Med.
