“…In vitro and in vivo studies of hip arthroplasty have indicated that crosslinking can reduce PE wear by up to 80%-90% [1,5]. The comparative wear studies have been reported on conventional UHMWPE and XLPE tested in a wear simulator/multidirectional motion pin-ondisc device against smooth and roughened femoral heads [17][18][19][20]. Most researchers have reported better wear resistance of XLPE than conventional UHMWPE [3,[17][18][19].…”

Most researchers have reported better wear resistance of XLPE than conventional UHMWPE [3,[17][18][19]. However, there are reports that XLPE is more sensitive to adverse conditions such as surface roughness effects of the femoral heads and third-body wear [3,[20][21][22].…”

The objective of this study was to investigate the wear resistance of ultrahigh‐molecular weight polyethylene (UHMWPE) and crosslinked polyethylene (XLPE) against different counterfaces. Friction and wear studies were evaluated under dry reciprocating sliding conditions at room temperature. Ti6Al4V discs finished in polished, lapped, and ground conditions were reciprocated against polymer cylinders. In addition, abrasive wear studies were conducted using different abrasive grit sizes. The friction and wear properties of the two polyethylenes were strongly affected by the different counterfaces. XLPE showed important friction and wear sensitivity with the change of surface roughness of the Ti6Al4V disc, as well as with the change in abrasive grit size. Scanning electron microscopy and energy‐dispersive X‐ray (EDX) analysis of the worn disc surfaces and the polymer pins indicated the wear mechanisms affecting the polyethylenes. POLYM. ENG.

Polyethylene (PE) remains the gold standard for the articulating surface in hip and knee arthroplasty. To increase arthroplasty longevity and improve wear resistance, newer versions of PE have been designed with resultantly different wear properties. Highly cross-linked polyethylene (HXLPE) is used in total hip arthroplasty with excellent outcomes; however, its use in total knee arthroplasty (TKA) remains conflicting. This review summarizes biomechanical and wear properties, clinical outcomes, and cost of polyethylene inserts in TKA. Simulation studies have convincingly shown decreased wear and oxidation rates with HXLPE when compared to conventional polyethylene (CPE). Registry results have been conflicting, and short-to midterm clinical studies have not demonstrated a significant difference between HXLPE and CPE. The cost of HXLPE inserts is higher than CPE. Long-term clinical data are lacking and further studies are warranted to evaluate the role of HXLPE in TKA.
