Double-row repair of rotator cuff tears: Comparing tendon contact area between techniques
Shao Hui Allan Ng, Chung Hui James Tan
Abstract
BACKGROUND: In rotator cuff repair surgery, the double-row technique is widely performed. Studies have shown that with increased contact area and pressure between tendon and bone interface, better healing is promoted. AIM: To assess the different suture configurations with the double-row technique and how this influences the contact area of the rotator cuff tendon to bone. METHODS: 1 medial, 2 lateral), were employed for three control groups. Each group consisted of eight shoulders with identical repair configurations. Footprint contact areas of the repaired tendon against the tuberosity were determined using pressure sensitive Fujifilm placed between the tendon and tuberosity. RESULTS: respectively. No statistical significance was noted between the three groups. CONCLUSION: In the technique of double-row repair, using a 3-suture anchor configuration may offer a non-inferior alternative to the standard 4-anchor construct in terms of efficacy. This may also result in overall cost reduction and shorter surgical time.
