This trial is to evaluate the effectiveness of the ArthroFLEX® ECM scaffold graph as an augment in rotator cuff repair surgery to reduce the failure rate of rotator cuff repairs for large and massive rotator cuff tears.
This is a prospective, randomized, controlled, multi-center clinical trial to evaluate the effectiveness of an ECM scaffold graft to augment repair of a large/massive rotator cuff tear. The study will involve 70 patients. 35 patients will be randomly assigned to each arm of the study.
Despite advances in surgical technology, repairs of large (3-5 cm) and massive (>5 cm) rotator cuff tears (RCT) fail between 20%-90% of the time [1]. Due to their size and increased structural involvement, large or massive RCT present a substantial challenge to orthopaedic surgeons. [16] The repairs tend to fail at the suture-tendon junction, which is due to several factors, including tension at the repair and quality of the tendon [1-2,5]. Full thickness tears are uncommon in younger patients, especially those less than forty years old and are usually traumatic in etiology. Younger patients also typically fair better following arthroscopic rotator cuff repair with fewer failures and more successful return to pre-injury level of function [16]. One strategy to augment repair of large to massive rotator cuff tears has been the development of biological scaffold materials, which are composed of extracellular matrix (ECM). The ECM composing the scaffolds are made from a number of tissues, including, but not limited to, small intestinal submucosa (SIS), dermis, and pericardium [3]. Studies to date include both prospective and retrospective in animal and human models, and include Restore, a porcine-derived SIS by DePuy Orthopaedics, GraftJacket, a human-derived, non-cross-linked dermis graft by Wright Medical Technology, and Zimmer Collagen Repair, a cross-linked porcine derived dermal graft made by Zimmer. Restore studies have shown no benefit and some even an increase in repair failure with recommendations not to use to augment repair. GraftJacket studies have shown a reduction in graft failure; however, several of the Restore and GraftJacket studies are limited by a lack of a control cohort. The Zimmer graft studies have conflicting results with both an improvement and no improvement in failure rates of repair. The prior studies listed are all in vivo; however, the majority are not randomized trials and thus do not have a control with which to compare data. In addition, some trials include open repairs. A lack of prospective, randomized, controlled, in vivo trials exist that evaluate the ability of the ECM scaffold graft augmentation in large to massive arthroscopic rotator cuff repairs to decrease the failure rate.
The purpose of this study is to evaluate the efficacy of using the Arthroflex (A-FLEX) graft to augment large to massive arthroscopic rotator cuff repairs in vivo and decrease repair failures in a prospective, randomized, controlled trial. By undergoing serial US examinations at follow-ups, we also intend to evaluate when during the postoperative period the failure of the repair occurs.

| ArthroFLEX ECM scaffold graft | Procedure | In patients receiving a graft, thru mini open technique the lateral portal incision will be extended vertically approximately 5-6 cm. A standard, deltoid-splitting, mini-open approach will then be performed, leaving the deltoid attachment to the acromion intact. For arthroscopic technique same method of fixation will be used below. The dermis graft will be sized and cut so as to cover the entire repair site in both medial-lateral and anterior-posterior dimensions. |

The patient self-evaluation section form contains visual analog scales for pain and activities of daily living questionnaire. The activities of daily living questionnaire is marked on a four-point ordinal scale that can be converted to a cumulative activities of daily living index. A shoulder score can be derived from the visual analogue scale score for pain (50%) and the cumulative activities of daily living score (50%). Scores range from 0 to 100. The higher the score, the better the outcome. |

| Patient Outcomes: Measurement of Shoulder Activity Level | This activity scale was developed using established principles: item generation, item reduction, pretesting, and reliability and validity testing. The activity rating is a numerical sum of scores for five activities rated on a five-point frequency scale from never performed (0 points) to daily (4 points). Patients were scored on the following criteria: carrying an object 8 lb or heavier by hand, handling objects overhead, weight training with arms, swinging motion (i.e., hitting tennis or golf ball), and lifting objects 25 lb or heavier. It can be used in conjunction with patient-based measures of shoulder outcome to define patient populations for cohort studies, and to assess activity level as a prognostic factor in patients with shoulder disorders. Scores range from 0 to 20. The higher the score, the better the outcome. | Preoperative |

| Treatment Group |
Patients randomly assigned into the treatment group will undergo open or arthroscopic rotator cuff repair with A-FLEX graft to augment the repair. ECM scaffold grafts are indicated for the reinforcement of soft tissues repaired by sutures or suture anchors during tendon repair surgery, including rotator cuff. ArthroFLEX ECM scaffold graft: In patients receiving a graft, thru mini open technique the lateral portal incision will be extended vertically approximately 5-6 cm. A standard, deltoid-splitting, mini-open approach will then be performed, leaving the deltoid attachment to the acromion intact. For arthroscopic technique same method of fixation will be used below. The dermis graft will be sized and cut so as to cover the entire repair site in both medial-lateral and anterior-posterior dimensions. |

The patient self-evaluation section form contains visual analog scales for pain and activities of daily living questionnaire. The activities of daily living questionnaire is marked on a four-point ordinal scale that can be converted to a cumulative activities of daily living index. A shoulder score can be derived from the visual analogue scale score for pain (50%) and the cumulative activities of daily living score (50%). Scores range from 0 to 100.

| Secondary | Patient Outcomes: Measurement of Shoulder Activity Level | This activity scale was developed using established principles: item generation, item reduction, pretesting, and reliability and validity testing. The activity rating is a numerical sum of scores for five activities rated on a five-point frequency scale from never performed (0 points) to daily (4 points). Patients were scored on the following criteria: carrying an object 8 lb or heavier by hand, handling objects overhead, weight training with arms, swinging motion (i.e., hitting tennis or golf ball), and lifting objects 25 lb or heavier. It can be used in conjunction with patient-based measures of shoulder outcome to define patient populations for cohort studies, and to assess activity level as a prognostic factor in patients with shoulder disorders. Scores range from 0 to 20. The higher the score, the better the outcome. | Posted | Mean | Standard Deviation | Units on a scale | Preoperative |

| EG001 | Treatment Group | Patients randomly assigned into the treatment group will undergo open or arthroscopic rotator cuff repair with A-FLEX graft to augment the repair. ECM scaffold grafts are indicated for the reinforcement of soft tissues repaired by sutures or suture anchors during tendon repair surgery, including rotator cuff. ArthroFLEX ECM scaffold graft: In patients receiving a graft, thru mini open technique the lateral portal incision will be extended vertically approximately 5-6 cm. A standard, deltoid-splitting, mini-open approach will then be performed, leaving the deltoid attachment to the acromion intact. For arthroscopic technique same method of fixation will be used below. The dermis graft will be sized and cut so as to cover the entire repair site in both medial-lateral and anterior-posterior dimensions. | 0 | 3 | 0 | 3 | 1 | 3 |
| EG002 | Alternative Treatment Group | Patients who meet pre-op inclusion criteria where a repair cannot be accomplished due to intraoperative findings will remain in the study. This group will be analyzed separately and still follow study procedures.
