BACKGROUND Total hip replacement (THR) is extremely common. Some prostheses fail, particularly in younger patients, and need to be revised, most commonly for loosening secondary to wear or dislocation. Surgeons have tried to address these problems by implanting large diameter metal-on-metal bearing surfaces. Our aim was to assess if metal-on-metal bearing surfaces lead to increased implant survival compared with other bearing surfaces in stemmed THR and, additionally, if larger head sizes… 
Failure rates of metal-on-metal hip resurfacings: analysis of data from the National Joint Registry for England and Wales
TLDR
Hip resurfacing only resulted in similar implant survivorship to other surgical options in men with large femoral heads, and inferior implant survival in other patients, particularly women, so it is recommended that resurfacing is not undertaken in women and that preoperative measurement is used to assess suitability in men.
Outcome of revised metal-on-metal hip arthroplasties: a Dutch arthroplasty register study
TLDR
Estimating re-revision rates after revision of a primary MoM hip arthroplasty in the Dutch Arthro Plasty Register (LROI) can be helpful in managing expectations of patients and orthopaedic surgeons.
Increased risk of revision of cementless stemmed total hip arthroplasty with metal-on-metal bearings
TLDR
At medium-term follow-up, the survivorship for cementless stemmed MoM THA was inferior to that for MoP THA, and metal-related problems may cause higher revision rates for MoM bearings with longer follow- up.
Distributed analysis of hip implants using six national and regional registries: comparing metal-on-metal with metal-on-highly cross-linked polyethylene bearings in cementless total hip arthroplasty in young patients.
TLDR
It is found consistent and strong evidence worldwide that large-head-size, metal-on-metal implants were associated with increased risk of revision after two years compared with metal- on-highly cross-linked polyethylene implants, with the effect becoming more pronounced over time.
The design of the acetabular component and size of the femoral head influence the risk of revision following 34 721 single-brand cemented hip replacements: a retrospective cohort study of medium-term data from a National Joint Registry.
TLDR
There were significant differences in failure between different designs of acetabular component and sizes of femoral head after adjustment for a range of covariates in cemented total hip replacement patients with osteoarthritis.

TLDR
A Markov model was developed to compare the cost-effectiveness of various implants against small-head cemented metal-on-polyethylene implants and found no evidence that uncemented, hybrid, or reverse hybrid implants were the most cost-effective option for any patient group.
Independent predictors of failure up to 7.5 years after 35 386 single-brand cementless total hip replacements: a retrospective cohort study using National Joint Registry data.
TLDR
Significant differences in failure between bearing surfaces and femoral stem size after adjustment for a range of covariates in a large cohort of single-brand cementless THRs are found.
Patient and implant survival following 4323 total hip replacements for acute femoral neck fracture: a retrospective cohort study using National Joint Registry data.
TLDR
THR is a good option in patients aged < 75 years and with ASA 1/2, but more research is required to determine the benefits of THR over hemiarthroplasty in older patients and those with ASA grades > 2.
A comparative assessment of small-head metal-on-metal and ceramic-on-polyethylene total hip replacement.
TLDR
Similar results were found for small-head MoM and CoP bearings up to ten years post-operatively, but after ten years MoM THRs had a higher risk of all-cause revision and the presence of an adverse response to metal debris seen in the small- head MOM group at revision is a cause for concern.
Predictive Factors for Revision and Survivorship Analysis of a Prevalent 36-mm Metal-on-Metal Total Hip Replacement System: A Large Single-Center Retrospective Cohort Study.
TLDR
Female gender and high femoral offset stems were significant predictors for all-cause revision and year of implantation was not significantly associated with an increasing number of revisions from 2007 onwards, although further studies to validate the impact of manufacturing discrepancies are recommended.

High failure rates with a large-diameter hybrid metal-on-metal total hip replacement: clinical, radiological and retrieval analysis.
TLDR
This hybrid metal-on-metal total hip replacement series has shown an unacceptably high rate of failure, with evidence of high wear at the trunnion-head interface and passive corrosion of the stem surface, which raises concerns about the use of large heads on conventional 12/14 tapers.
Risk of Complication and Revision Total Hip Arthroplasty Among Medicare Patients with Different Bearing Surfaces
TLDR
The risk of short-term complication (including dislocation) and revision THA were similar among appropriately matched Medicare THA patients regardless of bearing surface, and hard-on-hard THA bearings are of questionable value in Medicare patients.
Survivorship of second-generation metal-on-metal primary total hip replacement
TLDR
As there was no superior probability of survival, and there have been concerns on putative local and systemic toxicity of metal debris, the use of second-generation metal-on-metal articulations for primary THR remains moot.
Survival of Hard-on-Hard Bearings in Total Hip Arthroplasty: A Systematic Review
TLDR
As bearing designs continue to improve with modified materials and manufacturing techniques, use will increase, especially in young and active patients, though concerns remain about the increased reports of adverse events after metal-on-metal bearings.
Accelerating failure rate of the ASR total hip replacement.
TLDR
Wear at the modular junction is an important factor in the development of adverse tissue reactions after implantation of a large-diameter MoM THR, and co-ordinate measuring machine analysis of revised components showed that all patients suffering adverse tissue reacting in the resurfacing group had abnormal wear of the bearing surfaces.
Comparative survival of uncemented acetabular components following primary total hip arthroplasty.
TLDR
There are significant differences in the long-term survival of different types of uncemented acetabular components following total hip arthroplasty.
Results of 3,668 primary total hip replacements for primary osteoarthritis in patients under the age of 55 years
TLDR
The outcomes of total hip arthroplasty appear to have been relatively unsatisfactory for younger patients in Finland, and excessive wear of the polyethylene liner resulted in numerous revisions of modular cementless cups.
Five-year results of the ASR XL Acetabular System and the ASR Hip Resurfacing System: an analysis from the Australian Orthopaedic Association National Joint Replacement Registry.
TLDR
AsR prostheses used in conventional hip arthroplasty and in hip resurfacing exhibited a greater revision rate compared with other prostheses in the AOANJRR, consistent with those derived from other registries and from published studies of individual cohorts.
Optimal bearing surfaces for total hip replacement in the young patient: a meta-analysis
TLDR
A systematic review and meta-analysis of literature supports the use of MOM bearings in the management of the young arthritic hip and should be taken in the context of the limitations of such non-randomised study designs.
Medium-term Analysis of Modern Ceramic-On-Ceramic Bearing in THA
TLDR
Medium-term follow-up showed excellent clinical and radiological results of a modern ceramic-ceramic bearing and uncemented components in 107 hip arthroplasties, and it will be required to determine if this ceramic-on-cersamic bearing is associated with extended survivorship.
