Introduction

Structural failure after rotator cuff surgery has been reported as between 11% and 94%, with increased function in patients with intact rotator cuffs. Improved strength and long-term outcomes after rotator cuff repair are ultimately predicated upon successful tendon-to-bone healing.

Joint motion is commonly prescribed following tendon repair surgeries such as rotator cuff repairs; however, the ideal rehabilitation program to optimize tendon-to-bone healing is unknown. Prior studies have demonstrated the detrimental effects of immediate load, as well as both the detrimental and positive effects of immobilization; however, there is no literature to date describing the in vivo e
