Intervention / Treatment
Detailed Description
This is a prospective multi-center clinical study evaluating GraftJacket in the augmentation of large and massive rotator cuff tears compared to the traditional surgical technique of sutures and anchors alone. The study group will consist of 160 patients (early withdrawals or drop outs will not be replaced). Surgical approach for each patient will be either mini-open or arthroscopic. Safety assessments for this clinical study will be based on reported adverse events. Any adverse event that occurs during the study that represents a change from the patient's condition as noted at baseline [determined by normal standard of care] that is related to the procedure will be documented by completing the adverse events case report form.
Each investigator will indicate which operative technique (mini-open or arthroscopic) will be used during the study period at their site. The site selection process will be used to attempt to attain an equal distribution of both operative techniques used in the study. Patients will be randomly assigned to the treatment groups A or B. A randomization scheme using a 2 block model will be used within each surgical technique. Randomization cards meeting the requirements for this process will be generated by the statistician. Both surgical technique treatment groups will use the same assessments for comparisons throughout the study period.

Patients with reparable rotator cuff repairs must present with large and massive rotator cuff tears of more than 3cm, which can be repaired either arthroscopically or by open surgery to be eligible for enrollment. A reparable rotator cuff tear is defined as a tear of the rotator cuff where it is possible to bring the retracted tendon edge back to the greater tuberosity of the humerus without excessive tension. It should be possible to accomplish a watertight repair or only leave a residual defect of less than or equal to 1cm. The anteroposterior and mediolateral dimensions of the rotator cuff tear will be assessed intra-operatively by measurements either including the edges or after the edges are trimmed depending on the judgment of the surgeon. Rotator cuff tears involving the subscapularis tendon will not be included in the study, because the postoperative rehabilitation is more difficult and may confound the outcome results of either group. Surgical variables that should be documented on source documents and appropriate CRFs are the size of rotator cuff tear, the number of tendons involved, the type of repair (open, mini-open, arthroscopic) and the type and number of sutures and anchors.
Both clinical assessments and magnetic resonance imaging will be used to evaluate the effectiveness of the surgical techniques in both groups A and B. A screen/baseline MRI will be obtained of the affected shoulder during the preoperative visit. This MRI will be used to evaluate the extent of involvement and determine suitability for enrollment into the study including the size of the tear and extent of muscle atrophy. Images obtained within 3 months of signing consent may be used to assess eligibility for enrollment. Three additional follow-up MRIs of the affected shoulder will be obtained as part of the 2 year post-operative evaluation and will be used to evaluate structural success of group A, suture and anchor or group B, GraftJacket® allograft augmentation. The MRI scans performed at 6 months, 12 months and 24 months will be used to determine the rate of re-tear and to help to assess the integrity of the rotator cuff. Re-tears which are evident on the 6-month MRI will be considered a failure of the surgical technique, will be excluded from further follow-up within the study and followed separately. The comparison of the proportions of re-tears in patients in groups A and B who complete the MRI regimen through 2 years will be used to determine if GraftJacket® augmentation is a viable alternative to suture and anchor.
The Investigator will use clinical, functional, radiological, assessment of adverse events and assessment of the surgical techniques of groups A or B to evaluate each patient enrolled in this clinical study.
Pre Operative Procedures - Screen (Baseline)
Screening activities are performed during Visit 1. The protocol requires the following assessments during that visit:
- Informed consent process completed before any study related activities begin
- Inclusion/Exclusion criteria evaluation for study entry qualifications
- Magnetic Resonance Imaging (MRI)
- American Shoulder and Elbow Society (ASES) Scale
- University California Los Angeles (UCLA) Score
- Constant-Murley Score (CMS) Operative Procedures
The protocol requires completion of the following assessments during Visit 2:
- Open wound evaluation of rotator cuff tear for classification as large or massive with measurement of the tear to confirm size and length
- Enrollment confirmed using WMT randomization scheme for patient assignments Post Operative Procedures
Protocol requires the following assessments to be completed during the 1 month (plus 15 days) -Visit 3; 3 month (plus 15 days)-Visit 4; 6 month (plus 30 days) -Visit 5 and 12 month (plus 30 days) -Visit 6:
- MRI - Only performed during the 6 month (plus 30 day)-Visit 5 and 12 month (plus 30 days) -Visit 6
- ASES Scale
- CMS
- UCLA Score End of Study
Protocol requires completion of the following assessments during 24 month (plus 30 days)-Visit 7:
- MRI
- ASES Scale
- CMS
- UCLA Score
- Completion of End of Study Evaluation Form by the Principal Investigator
4.7 Scientific validity of the study design: Address the strengths and weaknesses of the selected design. Specifically indicate why a particular design was selected.
(1 page maximum - adhere to page limitations) Strengths: Prospective Randomized Clinical Trial Weakness: While not a true weakness, this trial is not randomized in the regular way but is using the "Expertise Randomization" style where the surgeon chooses his particular expertise of surgical repair of the rotator cuff (mini-open or arthroscopic) and the patients are randomized within that group.
A telephone randomization scheme cannot be used so there will be envelopes available to the surgeon in the OR for the group.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
less or no recurrence of shoulder rotator cuff tear with the use of the tissue scaffold than with the standard use of surgical anchors and screws as measured by MRI results
Time Frame: 2 years
|
each subject will be eligible for the study based on the Pre-operative results of the MRI as it relates to the size of the tissue tear.
The subjects will be assigned to either the tissue scaffold material or the standard surgical suture or anchors.
Then, the procedure to repair is determined by the investigator as an arthoscopic or open procedure.
Pos-operative evalutions via MRI will be obtained throughout the study to evaluate the effectiveness of the surgical procedure and for the measurement of retear or not.
