New Study Finds Positive Outcomes After Arthroscopic Shoulder Superior Capsular Reconstruction
While rotator cuff injuries are quite common, rotator cuff tears can be debilitating, occurring either over time from prolonged wear and tear or from an acute trauma injury. Complete rotator cuff tears are generally repaired by arthroscopic surgery. While surgical techniques have vastly improved over the years, a high re-tear rate still exists and some tears are not even able to be repaired primarily. For these cases, several salvage procedures exist. One is superior capsular reconstruction (SCR) which uses a graft to reconstruct the superior capsule of the shoulder in the region of the irreparable rotator cuff.
A new retrospective study from Hospital for Special Surgery (HSS) evaluated 72 patients who underwent arthroscopic SCR with dermal allograft to treat symptomatic irreparable rotator cuff tears. All patients were operated on at HSS between 2012 and 2017. Nearly 42% of the patients had a history of failed rotator cuff repair.
After surgery, the overwhelming majority of patients demonstrated significant improvements in forward elevation, abduction and external rotation through their pre- and post-operative active range of motion. At follow-up appointments, patients completed various patient-reported outcome surveys including Single Assessment Numeric Evaluation (SANE), American Shoulder and Elbow Surgeons (ASES), and University of California at Los Angeles (UCLA). Patient scores were high, averaging 80%, 78% and 85%, respectively.
Five patients required a second operation – no other complications were recorded.
“This technique has proven to be effective for patients with irreparable tears,” said Joshua S. Dines, MD, HSS sports medicine surgeon and senior study author. “As we continue to do more outcomes research, we become more precise at predicting the best candidates for each technique. While not for everyone, this has emerged as a great option for patients who may not be right for a reverse shoulder replacement.”
The authors look to perform future research evaluating the long-term outcomes and results.

Abstract Title: Clinical Outcomes following Arthroscopic Shoulder Superior Capsular Reconstruction
HSS is the world’s leading academic medical center focused on musculoskeletal health. At its core is Hospital for Special Surgery, nationally ranked No. 1 in orthopedics (for the tenth consecutive year), No. 3 in rheumatology by U.S. News & World Report (2019-2020), and named a leader in pediatric orthopedics by U.S. News & World Report “Best Children’s Hospitals” list (2019-2020). Founded in 1863, the Hospital has the lowest complication and readmission rates in the nation for orthopedics, and among the lowest infection rates. HSS was the first in New York State to receive Magnet Recognition for Excellence in Nursing Service from the American Nurses Credentialing Center four consecutive times. The global standard total knee replacement was developed at HSS in 1969. An affiliate of Weill Cornell Medical College, HSS has a main campus in New York City and facilities in New Jersey, Connecticut and in the Long Island and Westchester County regions of New York State, as well as in Florida. In addition to patient care, HSS leads the field in research, innovation and education. The HSS Research Institute comprises 20 laboratories and 300 staff members focused on leading the advancement of musculoskeletal health through prevention of degeneration, tissue repair and tissue regeneration. The HSS Global Innovation Institute was formed in 2016 to realize the potential of new drugs, therapeutics and devices. The HSS Education Institute is a trusted leader in advancing musculoskeletal knowledge and research for physicians, nurses, allied health professionals, academic trainees, and consumers in more than 130 countries. Through HSS Global Ventures, the institution is collaborating with medical centers and other organizations to advance the quality and value of musculoskeletal care and to make world-class HSS care more widely accessible nationally and internationally. www.hss.edu.
