Suture Anchor Economics & Construct Value

Evaluating commercial construct acquisition pricing against clinical recurrence, structural healing, and bone-preservation mechanics in shoulder reconstruction.

Interpreting Cost vs. Clinical Failure Across Indications: In arthroscopic Bankart repair, elevated historical recurrence (~18.5%) was driven primarily by insufficient anchor count (<3–4 anchors) and unaddressed glenoid bone loss or hyperlaxity (Boileau et al., 2006), rather than knotted vs. knotless material. When modern surgical indications and ≥3–4 anchors are applied, solid (PEEK/biocomposite) and knotless/all-suture anchors achieve statistically equivalent recurrence rates (~8–10%). Conversely, in large rotator cuff tears (>3 cm), higher-cost double-row/suture-bridge constructs substantially reduce anatomical re-tear rates on imaging (~11% vs. ~26% for single-row; Hein et al., 2015).

Bankart Fixation: Anchor Number vs. Material

• Primary Driver of Stability: Achieving ≥3–4 fixation points across the anteroinferior glenoid rim and addressing critical bone loss dictates clinical recurrence—not whether the anchor is knotted or knotless (Boileau et al., 2006; Jain et al., 2024).
• Where All-Suture / Knotless Adds Value: Rather than claiming lower re-dislocation rates, smaller-diameter (1.3–1.8 mm) all-suture anchors conserve narrow glenoid rim bone stock, avoid prominent intra-articular suture knots, and reduce perianchor osteolysis (Lee & Shin, 2025).

Rotator Cuff: Structural Healing vs. PROMs

• Anatomical Footprint Restoration: In tears >3 cm, transosseous-equivalent / suture-bridge constructs increase footprint contact pressure and significantly lower structural re-tear rates on MRI/ultrasound compared to single-row repairs (Hein et al., 2015; Duquin et al., 2010).
• Economic Justification: While short-term PROMs often appear similar, preserving tendon integrity lowers the risk of progression to cuff tear arthropathy and costly salvage reverse arthroplasty in active patients.
