The addition of vitamin E could reduce femoral head penetration of the polyethylene liners.

ABSTRACT:

Background

Vitamin E-diffused highly cross-linked polyethylene (HXLPE/Vit E) is a relatively advanced material used in total hip arthroplasty (THA) but whether it shows superiority is unclear.

Objective

This meta-analysis was performed to investigate the effect of HXLPE/Vit E liners in THA.

Methods

Medline/PubMed, Embase and Cochrane Library databases were searched to retrieve studies assessing the efficacy of HXLPE/Vit E liners in THA with the design of a randomized, controlled trial. Meta-analyses were conducted to merge the outcome estimates of interest, such as the femoral head penetration (FHP), FHP rate, FHP in x- (medial/lateral), y- (vertical) and z- (anteroposterior) axes, cup inclination angle, Harris hip score (HHS), numeric rating scale (NRS) and complicat
