Matrix Remodeling Accompanies In Vitro Articular Cartilage Spherical Shaping, Nathan Thomas Balcom

Master's Theses

Introduction: Articular cartilage (AC) is a low friction load bearing material found in synovial joints. The natural repair of damaged tissue is difficult and often requires surgical intervention. With large defects it becomes necessary to match the original tissue geometry. We hypothesized that localized collagen (COL) and/or proteoglycan (PG) remodeling occurs during AC spherical reshaping. The objective of this study was to determine the presence, magnitude and depth dependence of COL and PG remodeling that accompanies AC reshaping. Methods: Full thickness AC blocks (7x7 mm² surface area) were harvested from the ridges of the patellofemoral groove of immature (1-3 …
