“…Large animal models, such as goat, sheep, dog, calf, and rabbit, have proven to be suitable models for standard‐of‐care surgical techniques, robust mechanical loading, scaffold‐based repair strategies, and studies of muscle degenerative mechanisms, owing to the persistence of muscle atrophy and fatty infiltration as a consequence of chronic tendon release in these species. The limitations of the use of large animals include anatomic bone and soft tissue differences, cost, and the prolonged follow‐up required to demonstrate pathophysiologic changes .…”

Rotator cuff (RC) injuries represent a significant source of pain, functional impairment, and morbidity. The large disease burden of RC pathologies necessitates rapid development of research methodologies to treat these conditions. Given their ability to model anatomic, biomechanical, cellular, and molecular aspects of the human RC, animal models have played an indispensable role in reducing injury burden and advancing this field of research for many years. The development of animal models in the musculoskeletal (MSK) research arena is uniquely different from that in other fields in that the similarity of macrostructures and functions is as critical to replicate as cellular and molecular functions. Traditionally, larger animals have been used because of their anatomic similarity to humans and the ease of carrying out realistic surgical procedures. However, refinement of current molecular methods, introduction of novel research tools, and advancements in microsurgical techniques have increased the applicability of small animal models in MSK research. In this paper, we review RC animal models and emphasize a murine model that may serve as a valuable instrument for future RC tendon repair investigations.

“…A study by Brassart et al 45 highlights an issue regarding loss in footprint contact pressure after knotted repairs. The investigators showed that contact pressure was reduced by up to 60% immediately after tying the last knot in a mattress repair and contact pressure continued to fall over time, decreasing to 14% of the initial reading after 1 hour.…”

The ideal rotator cuff repair should have strong initial fixation strength to resist early structural failure and high footprint contact pressure to assist biological healing. Fixation strength can be enhanced by using more suture anchors in the repair construct and by placing anchors in area of high bone density such as the proximal part of the tuberosities. High footprint contact pressure can be achieved by using tension band repair constructs such as inverted mattress and suture bridge technique. These techniques pass sutures over the bursal surface of the tendon with lateral fixation. These bursal sutures push the tendon down to the footprint insertion creating a larger pressurized contact area beneficial for healing. Postoperative external rotation should be avoided to minimize strain on the anterolateral region of the repaired tendon. Abduction of 30 degrees should minimize loading stress on the repair construct and also facilitates blood flow to the footprint insertion.
