Comparison of the cheese-wiring effects among three sutures used in rotator cuff repair

Purpose: The goal of this study was to compare the cheese-wiring effects of three sutures with different coefficients of friction. Materials and methods: Sixteen human cadaveric shoulders were dissected to expose the distal supraspinatus and infraspinatus muscle tendons. Three sutures were stitched...

Description
Summary:Purpose: The goal of this study was to compare the cheese-wiring effects of three sutures with different coefficients of friction. Materials and methods: Sixteen human cadaveric shoulders were dissected to expose the distal supraspinatus and infraspinatus muscle tendons. Three sutures were stitched through the tendons: #2 Orthocord™ suture (reference #223114, DePuy Mitek, Inc., Raynham, MA), #2 ETHIBONDFNx01 EXCEL Suture, and #2 FiberWire® suture (FiberWire® , Arthrex, Naples, FL). The sutures were pulled by cyclic axial forces from 10 to 70 N at 1 Hz for 1000 cycles through a MTS machine. The cut-through distance on the tendon was measured with a digital caliper. Results: The cut-through distance in the supraspinatus tendons (mean ± standard deviation, n = 12) were 2.9 ± 0.6 mm for #2 Orthocord™ suture, 3.2 ± 1.2 mm for #2 ETHIBONDFNx01 suture, and 4.2 ± 1.7 mm for #2 FiberWire® suture. The differences were statistically significant analyzing with analysis of variance (P = 0.047) and two-tailed Student′s t-test, which showed significance between Orthocord™ and FiberWire® sutures (P = 0.026), but not significant between Orthocord™ and ETHIBONDFNx01 sutures (P = 0.607) or between ETHIBONDFNx01 and FiberWire® sutures (P = 0.103). Conclusion: The cheese-wiring effect is less in the Orthocord™ suture than in the FiberWire® suture in human cadaveric supraspinatus tendons. Clinical Relevance: Identification of sutures that cause high levels of tendon cheese-wiring after rotator cuff repair can lead to better suture selection.
