These authors sought to review their results with arthroscopic superior capsular reconstruction (SCR) using a decellularized porcine dermal xenograft in 56 patients with massive, irreparable rotator cuff tears. While the preoperative and postoperative ranges of motion were measured, these data were not reported.
Preoperative ASES, subjective shoulder values, and VAS scores were improved at two years ofter surgery. Eleven patients were pseudoparalytic prior to surgery; in five cases pseudoparalysis was reversed after SCR.
The anatomic failure rate in this study is unknown. The authors recognized 14 graft failures (25%) by MRI at a mean follow-up of 34 months; however, followup MRIs were only obtained on symptomatic patients with low scores in patient reported outcomes measures.
The relationship between anatomic failure and clinical failure was not investigated.
