“…The early complications from cementless femoral stems are clear; fibrous ingrowth, aseptic loosening, thigh pain, leg length discrepancy, and periprosthetic fracture contribute to the likelihood of secondary or revision surgery [2], [3], [4], [5], [6], [7], [49], [50]. These early complications have been shown to occur at lower rates with cemented femoral stems in most populations [2], [3], [4], [5], [6], [7], [49], [50].…”

“…These early complications have been shown to occur at lower rates with cemented femoral stems in most populations [2], [3], [4], [5], [6], [7], [49], [50]. With these secondary reoperations, there is an increase in the risk for dislocation, wound difficulties, infection and an overall increase in costly health care needs as well as increases in morbidity and mortality.…”

“…With the adoption of press-fit cementless femoral implants, the incidence of early complications, especially femoral periprosthetic fracture, resulting in early revision continues to increase [2], [3]. Other known risk factors for periprosthetic fracture include elderly patients, female gender, osteoporotic bone, and metabolic bone disease [2], [3], [4], [5], [6], [7].…”

BackgroundThere is now a clear trend with increased usage of cementless femoral stems for all ages and most patients. As the number of total hip arthroplasties (THAs) performed annually continues to increase with expanding indications for THA and demands for improved quality of life, so will the prevalence of THA in the elderly and aging populations. This is worrisome as the risk of complications with cementless femoral stems increases in elderly patients and those with poor bone quality. The purpose of this study is to analyze the available data from comparative studies to determine whether cementless femoral stems are overused and whether cemented stems warrant increased consideration.MethodsUsing Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, searches were performed to find original studies comparing cementless and cemented femoral stems; large population registry studies and reports were also included.ResultsThis systematic review documents that older patients with cementless fixation increase the risk of revision, there is no clear fixation advantage in midaged patients, and younger patients fare better with cementless fixation. Complications after THA create burdens on the health care system and on patients.ConclusionsUsing evidence-based data should be better guidance in selecting the most reliable implants for THA. Although cementless femoral fixation for THA has evolved to the “new standard,” it has not been proven to be the “gold standard” for all patients.

“…The causes include debonding of the components from the host bone with subsequent instability, or wear of the components with production of wear debris. This wear debris can disrupt bone metabolism leading to destruction of bone around the hip replacement (osteolysis), predisposing the patient to periprosthetic fracture (Harris, 2004;Katz, Wright, Polaris, Harris, & Losina, 2014).…”

Total hip arthroplasty (THA) is highly successful for reducing pain and improving function, providing health-related quality of life benefit. Demand for THA is increasing with associated increase in revision hip surgery. Hip arthroplasty surveillance (long-term follow up) can identify asymptomatically failing THA to prepare for revision surgery, reducing potential for complications or complexity of surgery. However, it is unknown whether the surveillance of THA can be shown to improve the patient outcomes or reduce costs around revision surgery. With the current need to reduce unnecessary health consultations and to show the economic advantages of any service, the purpose of this study is to consider the relative effectiveness of hip arthroplasty surveillance on revision hip arthroplasty. This is a single-centre, observational study in which consecutive patients undergoing aseptic revision of THA over 12 months in a large orthopaedic unit will be considered for participation. Primary outcome measures will be change in each of three valid patient-reported scores from pre-operatively to 12 months post-surgery. Secondary outcomes will be the costs of treatment calculated using data obtained from the participants' hospital records and a self-report questionnaire. An exploratory approach will be used to investigate the effect of surveillance on the outcomes of interest. A linear mixed method model will be used to study the change in scores between baseline and 12 months. The economic evaluation will be a cost-utility analysis, which compares the value of alternative interventions by attaching costs to the quality-adjusted life years produced by each intervention.

“…As one of the most commonly performed surgical procedures, this number is estimated to increase to 500,000 by the year 2030 [1]. The complications related to THRs are typically early failure that occur within the first five years after implantation in 10% of patients [2]. Thus, there is a high demand to get high quality, economical and sustainable implants.…”

Modern hip prostheses feature a modular implant design with at least one tapered junction. This design can lead to several complications due to the introduction of additional interfaces, which are subjected to various loading conditions and micromotion. The main objective of current study is to develop a fretting corrosion apparatus, which is able characterize the mechanical and electrochemical behaviour of various existing metal alloy couples during fretting motion. This study describes the design and the main considerations during the development of a novel fretting corrosion apparatus, as well as determination of the machine compliance and the initial testing results. Machine compliance considerations and frictional interactions of the couples are discussed in detail. For the preliminary tests, metal alloy pins, made of Ti6Al4V and wrought high-carbon CoCrMo were mechanically polished to a surface roughness of less than 20nm. 2 pins (Diameter = 11mm) of either Ti6Al4V or CoCrMo were loaded onto a Ti6Al4V alloy rod at a normal force of 200N. The interface types included: Ti6Al4V-Ti6Al4V-Ti6Al4V, Ti6Al4V-Ti6Al4V-CoCrMo, and CoCrMo-Ti6Al4V-CoCrMo. The Ti6Al4V rod articulated against the metal alloy pins in a sinusoidal fretting motion with a displacement amplitude of ±50μm. Bovine calf serum (30g/L of protein content) was selected as a lubricant and tested at 2 different pH levels (pH 3.0 and 7.6). In all cases, current and friction energy were monitored during the fretting process. The results indicated distinct, material-specific current evolutions and friction energies. No significant differences were observed in electrochemical or mechanical behaviour in response to pH change. In general, Ti6Al4V-Ti6Al4V-Ti6Al4V couples displayed the earliest passivation and superior electrochemical behaviour compared to Ti6Al4V-Ti6Al4V-CoCrMo and CoCrMo-Ti6Al4V-CoCrMo under fretting conditions. In addition, fluctuations in current were observed in specific regions at all instances where Ti6Al4V was coupled with Ti6Al4V. These fluctuations were not observed in instances where Ti6Al4V was coupled with CoCrMo. These findings suggest transitions in the degradation mechanisms at the modular junction as a function of material couples/contacts. The findings may assist in improving the current hip modular junctions.
