Three‐Anchor Knotless Compression Bridges Improve Contact Mechanics in a Biomechanical Model of Large, Single‐Row Tendon Repairs
Abstract
Purpose To investigate the influence of anchor density on tendon footprint contact mechanics in knotless all‐suture anchor compression bridge constructs. Methods Unicortical polyurethane solid foam blocks with a cancellous density of 20 lb/ft 3 and a cortical density of 40 lb/ft 3 simulated bone. Tendons were replicated with 4.76‐mm‐thick 40A durometer polyurethane rubber sized to 27 × 12 mm. Test groups consisted of two 2.6‐mm all‐suture anchor single‐row knotless compression bridge constructs evaluated at interanchor distances of 10, 15, 20, and 25 mm. A 3‐anchor construct was also evaluated for the 25‐mm (large tear) condition. The repair sutures of each construct were individually hooked onto a zeroed, handheld force gauge and manually tensioned to create a minor (
