“…In a porcine biomechanical study, Ahmad et al 36 found that suspensory cortical femoral fixation had higher ultimate failure load and less graft slippage than interference screws. Milano et al 37 and Miller et al 38 also showed that extracortical fixation has a mean load to failure of 700–1150 N. The failure load for interference screws in soft-tissue grafts is close to 450 N, which was termed by Noyes et al 39 as the physiological load that the knee has to withstand.…”

Background/objectiveThe Magellan Society is composed of > 150 high-volume fellowship-trained sports surgeons from four continents. These surgeons represent their regional sports organisations in travelling fellowships and are considered to be opinion leaders in their respective organisations. Prior to the 2014 Magellan Meeting in Arima, Japan, a survey was conducted to understand how Magellan members perform anterior cruciate ligament (ACL) reconstruction. This study aims to better understand how ACL reconstruction is performed by sports surgeons worldwide and to determine differences in surgical practice.MethodsA survey was conducted prior to the Magellan Meeting in Arima, Japan. Information on ACL graft of choice for primary surgery and revision surgery, preferred surgical techniques, and femoral and tibial graft fixation methods was collected. The incidence of meniscal tears and the management of injuries in ACL surgery were also studied. The results of the survey are discussed in this article.ResultsA response rate of 51% (72 member respondents) was achieved for this survey. Hamstring autograft (58%) was the graft of choice for primary ACL reconstruction. The next most common autograft used was bone patella tendon bone autograft (28%). Allograft was the graft of choice in only 4% of respondents. The region of origin of surgeons and the age of surgeons were factors in the ACL graft of choice. Seventy-five percent of surgeons practised single-bundle ACL reconstructions only, 22% performed both single-bundle and double-bundle ACL reconstructions, and 3% performed double-bundle ACL reconstructions exclusively. Sixty-two percent of the respondents drilled femoral tunnels using the anteromedial portal technique. Meniscus repairs were performed in 25% of ACL reconstructions, on average.ConclusionBased on the survey, hamstring transportal anatomic single-bundle ACL reconstruction with meniscus preservation is the preferred ACL reconstruction technique of high-volume fellowship-trained sports surgeons.

“…Ahmad CS et al found in a porcine biomechanical study that suspensory cortical femoral fixation had a higher ultimate failure load of 864 N and less graft slippage as compared to interference screw with a failure load of 539 N [77]. Various other authors have also shown that extracortical fixation has a mean load to failure of 700 N to 1150 N during biomechanical testing [78,79]. The failure load for the interference screw is close to 450 N, which is what Noyes terms the physiological load that the knee has to withstand [80].…”

The purpose of ESSKA- APOSSM Travelling fellowship is to better understand the epidemiology, management and surgical techniques for sports across continents. There has been a progressive evolution in ACL reconstruction and there is variation in technique in ACL reconstruction amongst the most experienced surgeons in different continents. During this one month fellowship, we saw various ACL reconstruction techniques using different graft sources, with a variety of graft fixation methods, with the common aim of recreating an anatomical ACL reconstruction.

“…Since secure fixation of a ligament is directly associated with postoperative outcomes, various types of fixtures are used in clinical practice [1]. Various fixtures are used in anterior cruciate ligament (ACL) reconstruction, including interference screws, post screws, double spike plate (DSP) screws and double staples [2][3][4][5][6], and their mechanical properties have been studied [7]. The Endo-Button, a suspensory cortical button, is widely used because it allows for easy and relatively strong fixation [8,9].…”

Background: Suspensory cortical buttons are widely used for fixation of reconstructed ligaments during anterior cruciate ligament (ACL) reconstruction because they have high usability and a favorable fixing force. However, it is not always easy to fix a reconstructed ACL while maintaining appropriate ligament tension. Therefore, we developed an improved cortical button that provides temporary tension until suturing is completed. Methods: Button holes of our improved EndoButton are not perpendicular to the bone surface on which the button is placed, but have an angle of 45 degrees so that the button can be temporarily fixed by applying tension to the suture. The improved EndoButton and the original EndoButton (Smith & Nephew Inc., Andover, Massachusetts) were each tied to FiberWire 5/7 metric (5 M) (manufactured by Arthrex). Ten cycles of preliminary loading (0-50 N) were applied to each suture, followed by test loading (0-250 N) for 500 or 1000 cycles. Then, a tensile test was performed at a displacement velocity of 20 mm/min. Results: The breaking strength of the sutures of the improved EndoButton were tend to higher than those of the sutures of the original EndoButton after 1000 loading cycles (p = 0.067, d = 0.883). The moduli of rigidity of the sutures of the improved EndoButton were higher than those of the sutures of the original EndoButton after 500 loading cycles (p = 0.027) and remained almost the same regardless of the number of loading cycles. Conclusion: We found that compared with the original cortical button, the improved cortical button was better able to retain suture breaking strength and modulus of rigidity, regardless of the number of load cycles.
