Articular cartilage and bone have distinctly different properties, rendering challenging the engineering of a robust interface that reduces stress concentrations and delamination. The osteochondral interface, which consists of a tidemark, calcified cartilage, cement line, and surrounding tissues, has a unique structure and function, but there is a dearth of quantitative data to describe it. Elucidating the structure–function relationships through characterization will be essential in defining design criteria for tissue engineering. Osteochondral engineering has used scaffold-based methods that, for example, use polymers in conjunction with ceramics. Excitingly, scaffold-free methods are emerging for engineering the articular cartilage layer, which can be interfaced with an underlying bone substrate.

A systematic review suggests that sexual dimorphism in the efficacy of regenerative rehabilitation approaches for the treatment of KOA may be partly attributed to the functional decline of female mesenchymal stem cells (MSCs) over the lifespan, particularly after menopause. These declines are likely to be accompanied by poor clinical outcomes. While evidence is far from adequate, physical therapeutics have emerged as a means to promote estrogen signaling in MSCs, potentially reversing menopause-related MSC dysfunction.
