Background 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. Methods 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. Results The contact area of the double-row technique was 42% greater than that of the transosseous technique (P <. 0001) and 60% greater than that of the single-row technique. The contact area of the transosseous technique was 31% greater than that of the single-row technique (P =. 0015). The average pressures of the single-row and double-row techniques were 18% (P =. 014) and 16% (P =. 03) greater, respectively, than that of the transosseous technique, but there was no significant difference between the single-row and double-row techniques (P =. 915). Conclusions 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.
