What material is commonly used for glenoid polyethylene in TSA?

The commonly used material for glenoid polyethylene in total shoulder arthroplasty (TSA) is ultra-high molecular weight polyethylene (UHMWPE). This material is favored due to its excellent wear resistance and biocompatibility, making it suitable for bearing surfaces in joint replacement. UHMWPE combines high strength with low friction properties, which are critical in reducing wear and prolonging the lifespan of the implant.

These attributes are especially significant in shoulder arthroplasty, where the glenoid component is subjected to multi-directional forces and motions. The durability of UHMWPE helps mitigate concerns about implant failure over time, promoting better clinical outcomes for patients. Other materials, while useful in various applications, do not offer the same combination of mechanical properties and biocompatibility necessary for glenoid components.
