The addition of vitamin E could reduce femoral head penetration of the polyethylene liners.
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 complications. Then pooled outcomes at different time points during the follow-up period were calculated.
Results: Follow an elaborate search of related databases, 23 studies involving a total of 54,920 participants were deemed eligible for this meta-analysis. The pooled results revealed significant decreased FHP at the last follow-up (pooled Mean Difference [MD] = -0.10, 95% confidence intervals [CIs]: -0.14 to -0.06). The subgroup analysis revealed a consistent trend at different time points during the follow-up. Significant decrease in the FHP rate were identified at the postoperative 1-2 years (pooled MD = -0.01, 95% CIs: -0.02 to -0.00) rather than at 2-5, 5-7, and 7-10 years. The combined results of clinical scores demonstrated no significant changes in the HHS, NRS, and EQ-5D variables. Additionally, no significant differences in the revision and cup inclination angle were identified during the follow-up period.
Conclusions: This study indicated that HXLPE/Vit E liner in total hip arthroplasty may decrease the femoral head penetration, mainly due to the decreased wear in proximal directions. However, no improvement on the clinical functions and complications were identified, and whether HXLPE/Vit E has the potential to prevent implant loosening or revision surgery could not be identified, which requires to be elaborated by high-quality randomized controlled trials.
期刊介绍：
Journal of Orthopaedic Surgery and Research is an open access journal that encompasses all aspects of clinical and basic research studies related to musculoskeletal issues.
Orthopaedic research is conducted at clinical and basic science levels. With the advancement of new technologies and the increasing expectation and demand from doctors and patients, we are witnessing an enormous growth in clinical orthopaedic research, particularly in the fields of traumatology, spinal surgery, joint replacement, sports medicine, musculoskeletal tumour management, hand microsurgery, foot and ankle surgery, paediatric orthopaedic, and orthopaedic rehabilitation. The involvement of basic science ranges from molecular, cellular, structural and functional perspectives to tissue engineering, gait analysis, automation and robotic surgery. Implant and biomaterial designs are new disciplines that complement clinical applications.
JOSR encourages the publication of multidisciplinary research with collaboration amongst clinicians and scientists from different disciplines, which will be the trend in the coming decades.
