Lower 5-year wear with vitamin-E infused HXLPE liner versus standard crosslinked liner in THA
Bone Joint J. 2018 Dec;100-B(12):1592-1599. doi: 10.1302/0301-620X.100B12.BJJ-2018-0371.R1208 patients (221 hips) scheduled for total hip arthroplasty were randomized to completion of surgery with either a vitamin E-infused highly crosslinked polyethylene liner (VEPE) or a moderately crosslinked polyethylene liner (ModXLPE). The primary purpose of this study was to compare liner wear via radiographic femoral head penetration between groups at 5-year follow-up. Results demonstrated significantly lower median total femoral head penetration in the VEPE group compared to the ModXLPE group at 5 years. When subgroup analyzed based on articulation type, the use of a ceramic femoral head demonstrated lower total liner wear relative to a metal femoral head within both groups. No patient in either group developed osteolysis or required revision for aseptic loosening. Clinical measures at 5 years, including pain and function, also did not significantly differ between groups.
