Aims. The purpose of this study was to evaluate whether an innovative
templating technique could predict the need for acetabular augmentation
during primary total hip arthroplasty for patients with dysplastic
hips. Patients and Methods. We developed a simple templating technique to estimate acetabular

Aims. Our first aim was to determine whether there are significant
changes in the level of metal ions in the blood at mid-term follow-up,
in patients with an Articular Surface Replacement (ASR) arthroplasty.
Secondly, we sought to identify risk factors for any increases. Patients and Methods. The study involved 435 patients who underwent unilateral, metal-on-metal

This study aimed to evaluate implant survival of reverse hybrid
total hip arthroplasty (THA) at medium-term follow-up. A consecutive series of 1082 THAs in 982 patients with mean follow-up
of 7.9 years (5 to 11.3) is presented. Mean age was 69.2 years (21
to 94). Of these, 194 (17.9%) were in patients under 60 years, 663
(61.3%) in female patients and 348 (32.2%) performed by a trainee.
Head size was 28 mm in 953 hips (88.1%) or 32 mm in 129 hips (11.9%).
Survival analysis was performed and subgroups compared using log
rank tests.Aims
Patients and Methods
There is little evidence on the cost effectiveness
of different brands of hip prostheses. We compared lifetime cost effectiveness
of frequently used brands within types of prosthesis including cemented
(Exeter V40 Contemporary, Exeter V40 Duration and Exeter V40 Elite
Plus Ogee), cementless (Corail Pinnacle, Accolade Trident, and Taperloc Exceed)
and hybrid (Exeter V40 Trilogy, Exeter V40 Trident, and CPT Trilogy).
We used data from three linked English national databases to estimate
the lifetime risk of revision, quality-adjusted life years (QALYs)
and cost. . For women with osteoarthritis aged 70 years, the Exeter V40 Elite
Plus Ogee had the lowest risk of revision (5.9% revision risk, 9.0
QALYs) and the CPT Trilogy had the highest QALYs (10.9% revision
risk, 9.3 QALYs). Compared with the Corail Pinnacle (9.3% revision
risk, 9.22 QALYs), the most commonly used brand, and assuming a
willingness-to-pay of £20 000 per QALY gain, the CPT Trilogy is
most cost effective, with an incremental net monetary benefit of £876.
Differences in cost effectiveness between the hybrid CPT Trilogy
and Exeter V40 Trident and the cementless Corail Pinnacle and Taperloc
Exceed were small, and a cautious interpretation is required, given
the limitations of the available information. However, it is unlikely that cemented brands are among the most
cost effective. Similar patterns of results were observed for men
and other ages. The gain in quality of life after
The aim of this prospective cohort study was to evaluate the early migration of the TriFit cementless proximally coated tapered femoral stem using radiostereometric analysis (RSA). A total of 21 patients (eight men and 13 women) undergoing primary total hip arthroplasty (THA) for osteoarthritis of the hip were recruited in this study and followed up for two years. Two patients were lost to follow-up. All patients received a TriFit stem and Trinity Cup with a vitamin E-infused highly cross-linked ultra-high molecular weight polyethylene liner. Radiographs for RSA were taken postoperatively and then at three, 12, and 24 months. Oxford Hip Score (OHS), EuroQol five-dimension questionnaire (EQ-5D), and adverse events were reported.Aims
Methods
There is widespread concern regarding the incidence of adverse soft-tissue reactions after metal-on-metal (MoM) hip replacement. Recent National Joint Registry data have shown clear differences in the rates of failure of different designs of hip resurfacing. Our aim was to update the failure rates related to metal debris for the Articular Surface Replacement (ASR). A total of 505 of these were implanted. Kaplan-Meier analysis showed a failure rate of 25% at six years for the ASR resurfacing and of 48.8% for the ASR
Aims. We present the clinical and radiological results at a minimum
follow-up of five years for patients who have undergone multiple
cement-in-cement revisions of their femoral component at revision
total hip arthroplasty (THA). Patients and Methods. We reviewed the outcome on a consecutive series of 24 patients
(10 men, 14 women) (51 procedures) who underwent more than one cement-in-cement
revision of the same femoral component. The mean age of the patients was
67.5 years (36 to 92) at final follow-up. Function was assessed using the original Harris hip score (HHS),
Oxford Hip Score (OHS) and the Merle D’Aubigné Postel score (MDP). Results. The mean length of follow-up was 81.7 months (64 to 240). A total
of 41 isolated acetabular revisions were performed in which stem
removal facilitated access to the acetabulum, six revisions were
conducted for loosening of both components and two were isolated
stem revisions (each of these patients had undergone at least two revisions). There was significant improvement in the OHS (p = 0.041), HHS
(p = 0.019) and MDP (p = 0.042) scores at final follow-up There
were no stem revisions for aseptic loosening. Survival of the femoral
component was 91.9% (95% confidence intervals (CI) 71.5 to 97.9)
at five years and 91.7% (95% CI 70 to 97) at ten years (number at
risk 13), with stem revision for all causes as the endpoint. Conclusion. Cement-in-cement revision is a viable technique for performing
multiple revisions of the well cemented femoral component during
revision

In order to assess current opinions on the long-term outcome after primary total hip replacement, we performed a multicentre, cross-sectional survey in 22 centres from 12 European countries. Different patient characteristics were categorised into ‘decreases chances’, ‘does not affect chances’, and ‘increases chances’ of a favourable long-term outcome, by 304 orthopaedic surgeons and 314 referring practitioners. The latter were less likely to associate age older than 80 years and obesity with a favourable outcome than orthopaedic surgeons (p <
0.001 and p = 0.006, respectively) and more likely to associate age younger than 50 years with a favourable outcome (p = 0.006). Comorbidity, rheumatoid arthritis, and poor bone quality were thought to be associated with a decreased chance of a favourable outcome. We found important differences in the opinions regarding long-term outcome after
