Background: To evaluate the efficacy and safety of a new hip prosthetic system compared with the control group.Methods: A total of 140 patients (140 hips) who met the inclusion criteria in three clinical institutions were selected. The main outcome were to judge the excellent and good rate of Harris score in the experimental group and the control group 5 years after operation, and whether the lower limit of the 95% confidence interval of the difference between the two groups was greater than the non-inferior threshold (the non-inferior cutoff value was-10%). The secondary outcome were the comparison of Harris scores, the number of adverse events, safety test and evaluation, the results of X-ray films and the concise health status questionnaire (SF-36) between the two groups before operation and after operation.Results: During the 5-year follow-up, the excellent and good rates of Harris scores in the experimental group and the control group were 96.8% and 96.7% respectively, and the rate difference was 0.1%. The lower limit of the 95% confidence interval was -8.9%, which was greater than the non-inferiority boundary value (the non-inferiority boundary value was-10%). There was no significant difference in Harris score, adverse events, safety test, imaging, and SF-36 analysis between the two groups before operation and after operation.Conclusion: The new combined hip prosthesis system meets the requirements of clinical safety and effectiveness, and is worth popularizing in clinical application.Trial registration: researchregistry, researchregistry5771.

What is appropriate surveillance for metal-on-metal hip arthroplasty patients?

The unexpected high revision rates of large-diameter (femoral head sizes of 36 mm or greater) metal-on-metal hip arthroplasties (MoMHAs) have led to worldwide regulatory authorities recommending regular surveillance, even for asymptomatic individuals. However, these recommendations are not evidence-based and are very costly. The rapidly evolving evidence base requires an update regarding the investigation and management of MoMHA patients. This article is the first of 2 (the second article in this series will consider the threshold for performing revision, and the outcomes following ARMD revision surgery: Matharu et al., Revision surgery of metal-on-metal hip arthroplasties for adverse reactions to metal debris: A clinical update. Acta Orthop 2018; in press), and considers the various investigative modalities used during surveillance, with specific focus on blood metal ion sampling and cross-sectional imaging. No single investigation can universally be used during MoMHA patient surveillance. Recent studies have now provided important information on interpreting blood metal ions (effective in identifying patients at low risk of problems), clarifying the roles of cross-sectional imaging (reserve combined ultrasound and MARS-MRI for complex cases), and providing parameters to safely exclude many asymptomatic patients from regular surveillance. This information will be useful when designing future surveillance protocols for MoMHA patients

Periprosthetic Pathology in ‘At Risk’ Ceramic-on-Polyethylene Total HIP Arthroplasty: A Clinical Study Using MARS-MRI in 50 Patients

Abstract: Soft tissue abnormalities after non-MoM THA are common in selected patients and can be clearly visualised with MARS-MRI. Pseudotumours as seen on MARS-MRI do occur in non-MoM hip arthroplasty but with low prevalence.
