Vitamin E-enriched polyethylene bearings are not inferior to Arcom bearings in primary total knee arthroplasty at medium-term follow-up.
The release of wear particles can be responsible for periprosthetic osteolysis, which can in turn, lead to aseptic loosening. Vitamin E-infused polyethylene (HXLPE Vit-E) has been shown, in vitro, to be more resistant to wear than conventional polyethylene (UHMWPE) by its crosslinking (HXLPE) and its higher resistance to oxidation. After reading a case report of a fracture of a vitamin E-enriched HXLPE bearing, the aim of this retrospective study was to evaluate fracture risk and clinical inferiority or not of vitamin-E HXLPE compared to conventional polyethylene in total knee arthroplasty (TKA). ⋯ Level III, therapeutic study.

Review Meta AnalysisCemented versus uncemented hemiarthroplasty for the management of femoral neck fractures in the elderly: a meta-analysis and systematic review.
Hemiarthroplasty is commonly used to treat unstable femoral neck fractures in older patients. However, there is no consensus on the use of cement during hemiarthroplasty. Therefore, we performed a systematic review to focus on the outcomes of cemented and uncemented hemiarthroplasty for the treatment of femoral neck fractures in older patients. ⋯ This meta-analysis showed cemented hemiarthroplasty might be an optimum choice for treating unstable femoral neck fractures in older patients. However, the results of this meta-analysis should be interpreted cautiously owing to some limitations. Further studies are required to provide more robust evidence.

Meta AnalysisPrevalence and risk factors for prolonged opioid use after total joint arthroplasty: a systematic review, meta-analysis, and meta-regression.
Opioids are a mainstay for pain management after total joint arthroplasty (TJA). The prevalence and risk factors for prolonged opioid use after TJA are important to understand to help slow the opioid epidemic. We aim to summarize and evaluate the prevalence and time trend of prolonged opioid use after TJA and pool its risk factors. ⋯ To our knowledge, this is the first meta-analysis determining the risk factors of prolonged opioid use and characterizing its rate and time trend in TJA. Understanding risk factors for patients with higher potential for prolonged opioids use can be used to implement appropriate management strategies, reduce unsafe opioid prescriptions, and decrease the risk of prolonged opioid use after TJA.

Review Meta AnalysisImpact of tourniquet during knee arthroplasty: a bayesian network meta-analysis of peri-operative outcomes.
The role of tourniquet during knee arthroplasty is controversial. The present study compares various tourniquet protocols using a Bayesian network meta-analysis of peri-operative data. ⋯ For knee arthroplasty, longer tourniquet use is associated with the shorter duration of surgery, lower intra-operative blood lost, lower drops in haemoglobin and fewer transfusion units. The shortest average hospitalisation was associated with no tourniquet use.
