Biomechanical Analysis of Pullout Strengths of Rotator Cuff and Glenoid Anchors: 2011 Update

Pullout strength of all suture anchors in the repair of rotator cuff tears: a biomechanical study

“…Tendon reinsertion is now usually done with suture threads mounted on anchors to restore attachment to bone. These metal, absorbable or polyetheretherketone (PEEK) anchors, screwed or impacted, are considered the reference device for tendon reinsertion [8,9]. Not all anchors have the same pullout strength or thread resistance, however [8,9].…”

Evaluation and Comparison of Eyelet Durability in Generic and Brand PEEK Rotator Cuff Anchors in Porcine Cortical and Cancellous Bone

“…Direct comparison with other RC anchors is limited due to cost considerations and the fact that most brand anchors had been tested [3,4]. Generic anchor test results are therefore compared to publish UFLs for several brand anchors in Table 3 noting that the published and current results were both obtained using calibrated measurement test instruments [4].…”

“…Anchors were inserted into cortical bone and subjected to Tests 1-3. Corkscrew FT anchors were chosen for comparison because they were not previously tested [3,4].…”

“…In a recent study of anchors inserted in fresh porcine humerus, the frequency of eyelet breakage was judged design dependent based on mechanical testing of various combinations of sutures and anchors [3,4]. Eyelets were the weakest element of anchors and therefore their performance is a primary concern.…”

Arthroscopic Repair of Ankle Instability With All-Soft Knotless Anchors

“…28 It induces minimal bony aggression stating no limitation to any subsequent surgical approach to that area. Being an all-suture anchor, it minimizes the risk of articular damage attributable to implant migration or implant failure.…”
