“…Due to many advantages such as excellent biocompatibility, high wear resistance and chemical stability with low biological reactivity and toxicity, and the reduction of abrasion particles. [ 16 , 17 ] Abrasion particles from joint lubricants can cause inflammatory reactions in tissues. This can lead to osteolysis and implant loosening.…”

Background: A diagnosis by magnetic resonance imaging (MRI) is often necessary before surgery of degenerative spine diseases. This can lead to a possible conflict with an inserted implant of the hip or knee. Heat generation or movement could be caused by the magnetic field. The aim of this study is to investigate temperature development in vitro in a 1.5T MRI of a ceramic knee arthroplasty. Methods: A full ceramic, complete metal-free non-constrained primary total knee arthroplasty is investigated. Temperature change was measured between platinum resistors before and after each MRI sequence by change of resistance. The knee implant was placed in a plastic container after the sensors were attached. Then the container was completely filled with ultrasound gel. To document any possible movement of the implant, a grid was placed under the container to document the position of the implant before and after the scans. Results: A total of four standard knee sequences were performed. The temperature at sites 1 to 5 per implant was always documented in the as-is state before MRI and then after each sequence. A total of 5 temperature measurement points were taken per implant. It was found that there were extremely small temperature variations. These were always in the range of less than 1°C. There was no case of movement of the implant triggered by the MRI scan. Conclusions: The experimental investigations carried out here showed homogeneous results with this experimental setup. It is concluded that, at least in vitro, that this ceramic knee implant can be used in MRI examinations without heating or movement.

“…The importance of identifying what a “normal” post-surgical recovery trajectory looks like for different groups of patients will be important for the assessment of new and often expensive surgical technologies (such as robotic surgery). The use of robotic surgery for THA and TKA is predicted to grow significantly over the coming years ( 23 ), as it is an attractive concept to both surgeons and patients. However, it currently comes with a high cost, and the proposed advantage of a quicker postoperative recovery is yet to be proven with physical performance outcome measures that are both sensitive and specific.…”

Introduction:The objective of our study was to investigate the association of safety-net hospital (SNH) status with the use of premium technologies in total hip arthroplasty (THA) using the American Academy of Orthopaedic Surgeons American Joint Replacement Registry. Methods: Premium technology was defined as having one or more of the following three characteristics: ceramic femoral head, dual mobility (DM) bearing, or surgery conducted with robotic assistance (RA). Patients of all ages were included and subdivided into ceramic femoral head, DM, and RA cohorts. SNH status (based on disproportionate share data), patient demographics, geographical region, hospital size, and teaching affiliation were assessed. Multivariate regression analysis was conducted to analyze any notable associations.Results: A total of 624,933 THAs between SNHs and non-SNHs were available for analysis. Based on the three different premium technology categories, there were 551,838 THAs for ceramic femoral head utilization analysis, 601,223 THAs for DM utilization analysis, and 199,250 THAs for RA utilization analysis. SNHs were associated with less use of DM and RA (odds ratio [OR] 0.53 P , 0.0001, 0.39 P , 0.0001, respectively). No difference was observed in ceramic femoral head utilization between SNHs and non-SNHs. Patient age was significantly associated with less utilization of all three premium THA technologies (ceramic: OR 0.43 P , 0.0001; DM: OR 0.93 P , 0.0001, RA: OR 0.89 P , 0.001). Teaching hospitals were significantly associated with increased utilization of premium THA technologies (ceramic: OR 1.23 P , 0.0001, DM: OR 1.62 P , 0.0001, RA: OR 5.33 P , 0.001). Conclusion: Premium THA technologies are becoming increasingly used across the US healthcare system; however, that growth is not equal in hospitals with marginalized patient populations. The
