ACL Implant Gains De Novo Authorization
FDA has granted a de novo marketing authorization for Miach Orthopedics’ anterior cruciate ligament (ACL) implant for ACL reconstruction to treat ACL tears. The Bridge-Enhanced ACL Repair (BEAR) Implant is an alternative to traditional reconstruction and does not require the use of harvested tendons for ACL repair. The device is a resorbable implant made from bovine collagen and is secured via suture to bridge the gap between the torn ends of a patient’s ACL. “The patient’s own blood is injected into the implant during the surgical implantation procedure with the intent of forming a device-protected clot that enables the body’s healing process,” an FDA release says. “Within about eight weeks of the BEAR Implant surgical procedure, it is absorbed and replaced by the body’s own tissue.”
Device authorization is based on data from a randomized controlled trial of 100 subjects with complete ACL rupture. 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), FDA says. “At the two-year mark, patients who received the BEAR Implant reported an average score of 88.6 and control subjects reported an average score of 84.6 using the International Knee Documentation Committee Subjective Score, a patient-reported outcome measure (questionnaire) that asks questions about symptoms related to pain and stiffness, sports activity and knee function,” it says. Those with the implant also had a laxity that, on average, was greater by 1.7 mm in the treated knee than that of the untreated knee, it says.
