Abstract

The principle of margin convergence applied to rotator cuff repair is achieved by side-to-side suture of the cuff tear in order to converge the free margin of the cuff toward its bone bed. This technique dramatically reduces strain along the "converged" margin, thereby protecting the tendon-bone repair interface during the critical phases of healing.
