Graft Source and Processing as Separate Exposures in Superior Capsular Reconstruction
Keywords:

Broad graft labels combine properties that may have different biological and clinical implications. Source, processing, storage, geometry, and delivery can vary together, making an observed outcome difficult to attribute to one material feature. This conceptual synthesis develops an exposure definition for superior capsular reconstruction. A review of graft biology motivates the distinction, while reconstruction research and causal methods clarify the evidence needed for comparison. The framework separates source identity from measured construct properties, places processing on an explicit timeline, and examines overlap among the strategies available to patients. It treats biological plausibility as a hypothesis-generating resource rather than a substitute for comparative outcomes. No specimens, operative records, or patient outcomes are newly analyzed. The contribution is a design for describing what was implanted and what a clinical comparison can legitimately estimate when nominal graft categories contain multiple treatment versions.
