BEAR is a new technique that uses a collagen scaffold instead of a graft to repair the ACL. 2009;17:77-79. Outcomes-including the IKDC Subjective Score, the side-to-side difference in instrumented AP knee laxity, and muscle strength-were assessed at 2 years by an independent examiner blinded to the procedure. is a founder, paid consultant, and equity holder in Miach Orthopaedics, Inc, which was formed to work on upscaling production of the BEAR scaffold. PMID: 24646218. Meaning the cartilage destruction markers after an ACL reconstruction surgery are similar to those seen right after the original injury, causing a double hit to the cartilage. PMID: 26261424; PMCID: PMC4527573. Background: Preclinical studies suggest that for complete midsubstance anterior cruciate ligament (ACL) injuries, a suture repair of the ACL augmented with a protein implant placed in the gap between the torn ends (bridge-enhanced ACL repair [BEAR]) may be a viable alternative to ACL reconstruction (ACLR).

Mansour J, Ghanimeh J, Ghoul A, Estephan M, Khoury A, Daher M. SICOT J. Orthop J Sports Med. The problem is that the recent research from Harvard shows that drilling these graft tunnels likely means a significant second severe inflammatory hit to the cartilage (2-4). ACL reconstruction; ACL repair; BEAR; anterior cruciate ligament; bridge-enhanced ACL repair; human; scaffold-enhanced ACL repair. The BEAR III trial was designed to evaluate the effects of age on outcomes following the BEAR procedure. 8600 Rockville Pike At two years, control subjects had a laxity that, on average, was greater by 1.8 mm in the treated knee than that of the untreated knee. BEAR-MOON is an acronym for BEAR (Bridge-Enhanced ACL Restoration) MOON (Multicenter Orthopaedic Outcomes Network). from 8 AM - 9 PM ET. In a statement, Martha Shadan, president and CEO of Miach Orthopaedics, said the implant represented the first substantial advancement in the treatment of ACL tears in decades. The FDA, an agency within the U.S. Department of Health and Human Services, protects the public health by assuring the safety, effectiveness, and security of human and veterinary drugs, vaccines and other biological products for human use, and medical devices.

Further work is planned Perhaps the single biggest question from an athlete is, When can I return to play? For ACL surgery, the current recommendations are 1-2 years. Background: While a sex effect on outcomes following anterior cruciate ligament (ACL) reconstruction surgery has been previously documented, less is known following bridge-enhanced ACL repair (BEAR). 2016;44(7):16601670. Unauthorized use of these marks is strictly prohibited. Upper left panel: A suture (purple) is placed through the tibial stump via a whipstitch and secured with 2 free sutures (green) to an extracortical button. That may be tough to do using an MRI report, as the reading radiologist often doesnt differentiate between the two tear types. This is a potential problem as the natural ACL has two bands that cross each other (hence the name Cruciate, which in Latin means cross). D.E.K. In total, 96% of the patients returned for 2-year follow-up. TheLifespan Orthopedics Institute is managing the only New England site, one of six across the nation, to conduct the trial with our partner physicians at University Orthopedics. At two years, control subjects had a laxity that, on average, was greater by 1.8 mm in the treated knee than that of the untreated knee. Patients with the implant had an average that was greater by 1.61 mm in the treated knee compared to their untreated knee. 2020 Jul;26(13-14):702-711. doi: 10.1089/ten.tea.2020.0057. Dr. Fleming: ACL reconstruction surgery in active patients has been the gold standard treatment for more than three decades. Females Have Earlier Muscle Strength and Functional Recovery After Bridge-Enhanced Anterior Cruciate Ligament Repair. Epub 2018 Jul 22. The gold standard of ACL rupture is using a graft of tendon to replace the ACL, Fleming explains. The BEAR Implant is a resorbable implantmeaning it is absorbed by the bodymade from bovine collagen and is secured via suture to bridge the gap between the torn ends of a patient's ACL. HHS Vulnerability Disclosure, Help maintained a conflict-of-interest management plan that was approved by Boston Childrens Hospital and Harvard Medical School during the conduct of the trial, with oversight by both conflict-of-interest committees and the institutional review board of Boston Childrens Hospital, as well as the US Food and Drug Administration. It is indicated for skeletally mature patients at least 14 years of age with a complete rupture of the ACL, as confirmed by MRI. Keywords: The upshot? Unauthorized use of these marks is strictly prohibited. The FDA granted marketing authorization for an implant to repair the injury. The Bridge-Enhanced ACL Repair (BEAR) Implant is an alternative to ACL reconstruction, which typically requires harvesting tendonsand sometimes bonefrom another part of the patients body or a deceased donor. 90 clinic locations offering non-surgical Regenexx solutions for musculoskeletal pain. To learn more, see my video below: Our research has shown that for the right type of tears, you end up with MRI and functional evidence of a repaired ACL. So as the ACL cells move into the implant, they absorb the protein of the implant and replace it with new protein organized like the native ACL, she tells Verywell. Thus, there remains a need to find a new method that is less invasive and has the potential to provide better outcomes. Ive summarized the comparison above. Tang C, Kwaees TA, Accadbled F, Turati M, Green DW, Nicolaou N. J Child Orthop. Her discoveries led to the conceptualization of an implant that could be placed between the torn ends of the ACL to bridge the gap, which is then mixed with the patients own blood to stimulate healing. Epub 2023 Apr 13. The request was submitted under section 513(f)(2) of the FD&C Act. ACL reconstruction surgery has been a staple of modern sports medicine for decades. Epub 2016 May 13. Compared to traditional ACL reconstruction, the implant is a less invasive procedure that restores the knee's natural anatomy and function. It is indicated for skeletally mature patients at least 14 years of age with a complete rupture of the ACL, as confirmed by MRI. PMID: 20810079. The bridge enhanced ACL restoration (BEAR) procedure provides the ability to perform primary repair of the acutely torn ACL's via utilization of a proprietary protein based scaffold. 2015 Jul 31;8:437-47. doi: 10.2147/JPR.S86244. Compared to traditional ACL reconstruction, the implant is a less invasive procedure that restores the knees natural anatomy and function. Outcomes reported included International Knee Documentation Committee (IKDC) subjective and objective results, knee anteroposterior (AP) laxity findings via an arthrometer, and functional outcomes. The FDA assessed the safety and effectiveness of the BEAR Implant in a randomized controlled trial of 100 subjects with complete ACL rupture. -, Anderson AF, Irrgang JJ, Kocher MS, Mann BJ, Harrast JJ; International Knee Documentation Committee. The BEAR-MOON trial addresses the question of whether this new and less invasive surgical procedure can provide non-inferior outcomes to the gold standard of treatment in terms of knee laxity, a common test to evaluate the integrity of the ACL, and patient-reported outcomes. 2016 Oct;44(10):2579-2588. doi: 10.1177/0363546516655333. Epub 2013 Jun 28. The BEAR Implant from Miach Orthopaedics was approved by the U.S. Food and Drug Administration in December 2020. Murray MM, Fleming BC, Badger GJ; BEAR Trial Team; Freiberger C, Henderson R, Barnett S, Kiapour A, Ecklund K, Proffen B, Sant N, Kramer DE, Micheli LJ, Yen YM. In the study, 65 patients received the BEAR Implant and 35 members of the control group received ACL reconstruction with autograft (using their own tendon from another part of the body). The device, the Bridge-Enhanced ACL Repair (BEAR) Implant, unlike traditional reconstruction, does not require the use of harvested tendons for ACL repair and is the only currently- available alternative to reconstruction with allograft, autograft or suture-only repair for the treatment of ACL rupture. If you have questions or comments about this blog post, please email us at [emailprotected]. 2018;26:1362-1366. Whether it replaces ACL reconstruction as the gold standard remains to be seen but I am optimistic it will, Fleming adds.

Along with this authorization, the FDA is establishing special controls for devices of this type, including requirements related to labeling and performance testing. Migliorini F, Vecchio G, Eschweiler J, Schneider SM, Hildebrand F, Maffulli N. J Orthop Traumatol. Assuming that orthopedic surgeons apply BEAR to the correct patients, these two procedures should never really compete head to head. National Library of Medicine Harvard Health Publishing. Stepwise demonstration of the bridge-enhanced, Stepwise demonstration of the bridge-enhanced anterior cruciate ligament repair (BEAR) technique using the, Magnetic resonance imaging from the 9 patients in the bridge-enhanced anterior cruciate ligament, Magnetic resonance imaging from the 7 patients in the anterior cruciate ligament reconstruction, MeSH The advantages are: In past decade, we have published two MRI analysis case series demonstrating good healing of the ACL with the Perc-ACLR procedure (16,17). First, BEAR allows the ACL to repair itself rather than ripping out the ACL remnants and placing a tendon as a substitute. Please enable it to take advantage of the complete set of features! Bridge-Enhanced Anterior Cruciate Ligament Repair Is Not Inferior to Autograft Anterior Cruciate Ligament Reconstruction at 2 Years: Results of a Prospective Randomized Clinical Trial. Do you have a torn ACL? Am J Sports Med. Regenexx Perc-ACLR has been performed since 2012. AOSSM has not conducted an independent investigation on the OPD and disclaims any liability or responsibility relating thereto. R01 AR056834/AR/NIAMS NIH HHS/United States, R01 AR065462/AR/NIAMS NIH HHS/United States, Abourezk MN, Ithurburn MP, McNally MP, et al. However, the BEAR technology has the potential to transform the way we treat ACL injuries, with restoration of the native ligament and without the need to harvest a graft from another part of the knee. J Pain Res. The purpose of this study was to report the 12- and 24-month outcomes of patients who underwent the BEAR procedure compared with a nonrandomized concurrent control group who underwent ACL reconstruction (ACLR) with an autograft. U.S. Food and Drug Administration. (D) The ends of the torn ACL then grow into the scaffold, which is gradually replaced by healing ligament tissue. who did mahalia jackson marry, abandoned hospitals in ohio, jenni rivera house zillow,
