Mitek Sports Medicine, part of DePuy, itself part of J&J, is releasing the HEALIX ADVANCE KNOTLESS Anchor for arthroscopic rotator cuff repairs. Here are some details about the device from Mitek:
The HEALIX ADVANCE KNOTLESS Anchor features dual-thread technology to maximize fixation and pull-out strength in both cancellous and cortical bone, and a multi-thread design that enables fast insertion into bone. Additionally, the device eliminates the need for arthroscopic knot tying.
The HEALIX ADVANCE KNOTLESS Anchors are offered in three sizes, 4.75mm, 5.5mm and 6.5mm and are made of either BIOCRYL® RAPIDE™, a biocomposite material that allows absorption and boney ingrowth at the implant site, or radiolucent polyetheretherketone (PEEK), a biocompatible thermoplastic material. The anchors hold up to six strands of the company’s ORTHOCORD® High Strength Orthopaedic Suture or two strands of high strength tape-suture. The new knotless anchor requires no new instrumentation.
In performance testing, HEALIX ADVANCE KNOTLESS Anchors displayed higher pullout strength when compared to other knotless anchors tested in the 4.5mm/4.75mm size range, and equivalent performance when compared to knotless anchors tested in the 5.5mm size.
The unique cortical threads and flare of the HEALIX ADVANCE KNOTLESS Anchor allows for cortical fixation of suture to bone, which enables more fixation points than other knotless anchors. Other features include an inserter ring that keeps sutures aligned along the shaft and prevents suture wrapping inside the subacromial space and cannula.
