The contact pressure and contact area at the tendon-bone interface after the most commonly used rotator cuff repair methods have not been investigated.
Hypothesis: There are no significant differences among the transosseous, the single-row suture anchor, and the double-row suture anchor techniques in terms of contact pressure, contact area, and pressure patterns at the tendon-bone interface.
Study Design: Controlled laboratory study.
After creating a full-thickness supraspinatus tendon tear in 10 cadaveric shoulder specimens, we inserted pressure-sensitive film between the tendon stump and the bone, and we repaired the tear by (1) transosseous, (2) single-row suture anchor, and (3) double-row suture anchor techniques.
The double-row technique produced the greatest contact area and the second-highest contact pressure, whereas the single-row technique created the highest contact pressure and the least contact area. The transosseous technique produced the second-greatest contact area and the least contact pressure.
Clinical Relevance: The double-row suture anchor technique and the transosseous technique may provide a better environment for tendon healing.
