Comparison of Partial Rotator Cuff Repair vs. Superior Capsular Reconstruction for Irreparable Rotator Cuff Tears

February 9, 2026 updated by: Robert J. Gillespie, University Hospitals Cleveland Medical Center
The primary objective of this prospective randomized controlled trial is to compare pain and functional outcomes between two surgical modalities for irreparable rotator cuff tears as measured by the pain visual analog scale (VAS), simple shoulder test (SST), American Shoulder and Elbow Surgery shoulder score (ASES), and Patient Reported Outcomes Measurement Information System (PROMIS) 29 score at 6 weeks, 3, 6, 12, and 24 months post-operatively. The two surgical modalities of interest are partial rotator cuff repair alone and partial rotator cuff repair with superior capsule reconstruction (SCR). The secondary objective of this study is determine the failure rate of partial repair alone vs. partial repair with SCR via magnetic resonance imaging (MRI) at 12 months post-operatively. The information gained from this investigation will be useful to discern if SCR provides any benefit to patients with irreparable rotator cuff tears. The investigators hypothesize that there is no statistically significant difference in pain and functional outcomes between partial rotator cuff repair alone versus partial rotator cuff repair with SCR. In addition, the investigators hypothesize that the failure rate will be significantly higher in patients undergoing partial rotator cuff repair with SCR.

Study Overview

Detailed Description

Rotator cuff injury is a commonly encountered problem within the United States. In most cases, surgical repair can reduce pain and restore baseline functional status. However, in the case of an irreparable rotator cuff tear, management becomes more challenging as these injuries tend to be larger in size, are inelastic secondary to tendon retraction, and exhibit fatty infiltration and rotator cuff atrophy1. A multitude of surgical approaches for an irreparable rotator cuff tear have been described in the literature, including partial repair alone, partial repair with superior capsular reconstruction (SCR), arthroscopic debridement, graft interposition, balloon spacer arthroplasty, tendon transfers, and reverse total shoulder arthroplasty (rTSA)2. In younger patients, the traditional approach to managing these injuries involved partial rotator cuff repair with subacromial decompression and debridement with the hopes of providing the patient with some restoration of function and pain relief3,4. Clinical studies have demonstrated that partial repair can lead to an improvement in pain and function in the early post-operative period; long-term outcomes following this procedure were less reliable3. In addition, a high rate of failure has been associated with partial rotator cuff repair alone. Partial repair with SCR is a relatively new surgical procedure that has become an increasingly popular treatment modality in recent years because of early promising biomechanical and functional outcomes5,6. However, there have been no prospective randomized assessments of SCR. Therefore, the long-term outcomes of SCR compared to the standard of care, namely partial rotator cuff repair, are unknown.

This will be a multi-center, prospective randomized controlled trial. Prior to enrollment, patients will be screened for inclusion criteria. Participants who meet the eligibility criteria and are suspected to have an irreparable rotator cuff tear will be randomized into one of the two treatment arms prior to surgery. Group 1 will receive partial rotator cuff repair alone while group 2 will receive partial rotator cuff repair with SCR. All patients with suspected irreparable rotator cuff tears will be consented in clinic. There is the potential situation where the surgeon believed that the rotator cuff tear was irreparable based on clinical and radiographic evidence but was able to completely repair the tear intraoperatively. Based on the modified intention-to-treat (mITT) principle, these select patients will be dropped from the study and will no longer be followed for research purposes. Randomization will occur with a stratified randomization excel spreadsheet. Each group will be followed post-operatively for 24 months. The primary objective of this study is to compare pain and functional outcomes between the two treatment arms. The secondary objective is to assess the failure rate between the two treatment arms.

Study Procedures

  1. All patients with a strongly suspected irreparable rotator cuff tear will be identified in the clinics of the treating physicians and be screened for inclusion and exclusion criteria. The consent form will be reviewed in depth with the patients by an IRB-approved member of the study team, and all questions will be answered prior to enrollment in the study. Patients will be asked if they need additional time to review the consent, and no coercion will occur throughout the consent process. Although patients will be consented at this clinic visit, they will be informed that there is a possibility that they will ultimately be excluded from the study because an irreparable rotator cuff tear can only be confirmed intraoperatively.
  2. At the initial pre-operative clinic visit, patient demographics will be collected and the pain and functional status of patients will be assessed using VAS, SST, ASES, and PROMIS-29 scores. It should take approximately 15 minutes to complete these surveys in clinic.
  3. Patients requiring medical clearance to ensure their health is optimized for surgery will do so. After receiving medical clearance (if needed), the patients will undergo surgery.
  4. Patients will be randomized prior to surgery into one of two possible treatment arms as described above. Stratified randomization will be performed with Microsoft Excel. If a patient, who was suspected to have an irreparable rotator cuff tear based on clinical and radiographic findings, is amenable to a complete rotator cuff tear, they will be dropped from the study and no longer followed for research purposes. This is based on the mITT principle.
  5. On the day of surgery, the patient will receive either a partial rotator cuff repair alone or a partial rotator cuff repair with SCR.
  6. Intraoperative data will be collected. For both groups, the investigators will assess if the following were performed during the procedure: subacromial decompression, biceps tenotomy vs. tenodesis, marginal convergence, single vs. double-row repair, and repair of the subscapularis muscle. For the SCR group, the size (mm2) and width (mm) of the acellular dermal allograft will be recorded. Finally, any complications that occur intraoperatively will be recorded for both groups.
  7. After discharge from the surgery center, both groups of patients will be given identical pain medication regimens, post-operative restrictions, and clinical follow-up schedule. They will be instructed to follow-up in clinic at 6 weeks, 3, 6, 12, and 24 months post-operatively.
  8. At each post-operative appointment, the patients will again be administered the VAS, SST, ASES, and PROMIS-29 questionnaires. Complications will be assessed at each visit. In addition, at the 12-month follow-up appointment, each patient in both groups will be given a prescription for an MRI of the operative shoulder to assess for failure of the repair.
  9. Key variables for analysis will be found within the electronic medical record, and in questionnaires administered at clinic appointments. They include: age at time of surgery, sex, height, weight, hand dominance, laterality of surgery, mechanism of injury, and surgical complications (e.g., infection, failure of repair).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Superior Capsular Reconstruction
Superior capsular reconstruction is one treatment option for massive and irreparable rotator cuff tears. The superior shoulder capsule, a thin membranous structure located on the inferior surface of the supraspinatus and infraspinatus muscles, is often torn in this type of rotator cuff tear. In superior capsular reconstruction, this structure is reconstructed with acellular dermal allograft.
Placebo Comparator: Partial Rotator Cuff Repair
Partial rotator cuff repair can be performed, in conjunction with other procedures such as subacromial decompression and biceps tenodesis, when a rotator cuff tear is not amenable to a complete repair.
