Expiration: 2029-09-30

The Arthrex AR-4580 is a professional-grade, sterile, single-use orthopaedic arthroscopy instrument expertly engineered to perform rapid, high-strength, "all-inside" repairs of torn knee meniscal cartilage. Part of the specialized FiberStitch™ 1.5 product portfolio, this device features an ergonomic, low-profile mechanical handle mated to a curved delivery needle designed to navigate safely around femoral condyle contours and access the medial or lateral joint gaps. Unlike rigid legacy platforms that utilize hard plastic PEEK toggles, the AR-4580 is an "all-suture" fixation system pre-loaded with two soft, ultra-low-profile polyester implants linked together by a high-tensile, non-absorbable size 2-0 coreless FiberWire® suture loop. Operating via a tactile manual trigger, the system sequentially deploys the soft anchors behind the knee joint capsule, transforming them into flat, low-profile cushions that compress and stabilize the vertical or longitudinal meniscus tear. This all-suture architecture significantly decreases localized tissue morbidity, protects adjacent articular cartilage surfaces from scratching or friction damage, and provides excellent biomechanical fixation strength to support accelerated patient post-operative loading milestones.
