A massive, retracted tear of the rotator cuff poses a unique challenge to the orthopaedic surgeon. All at- tempts must be made to mobilize the tendons such that they can be repaired to their anatomic insertion sites on the greater tuberosity in a tension-free manner. However, many retracted tears cannot be fully mobilized. In this situa- tion, there is substantial controversy over the most successful repair technique.
The advent of double-row re pairs has been a substantial advance in rotator cuff repair. The double-row technique has been shown to be biomechanically superior to single-row and transosseous suture techniques 1-4. However, the studies com- paring these repair constructs have subjected all specimens to the same loads, failing to account for differences in tension be- tween the repair constructs
