Retrospective histologic study of 7 biopsy specimens harvested during second-look arthroscopy in patients who had undergone rotator cuff repair augmented with a highly porous reconstituted bovine collagen implant. Examines how the implant integrates with host tissue, how collagen matures, and whether the implant provokes any adverse tissue reaction across time points spanning 5 weeks to 6 months.
When counseling patients after collagen-augmented rotator cuff repair, this histologic timeline supports expecting biologically integrated, tendon-like tissue by 6 months with complete implant resorption — and reassures that the absence of inflammatory reaction in all 7 human specimens validates safety signals previously seen only in animal models.
