A crucial introduction to the existing myofascial discomfort novels -- Present cards 2021.
In addition, PROM-driven QALYs may be used to analyze novel spine surgical techniques for value-based improvements.BACKGROUND Patellofemoral arthroplasty (PFA) is one option for the treatment of isolated patellofemoral osteoarthritis, but there are limited data regarding the procedure and results. Because isolated patellofemoral arthritis is relatively uncommon, available case series generally are small, and even within national registries, sample sizes are limited. Combining data from multiple registries may aid in assessing worldwide PFA usage and survivorship. QUESTIONS/PURPOSES We combined and compared data from multiple large arthroplasty registries worldwide to ask (1) What proportion of patients undergoing primary knee arthroplasty have PFA? (2) What are the patient and prosthesis characteristics associated with PFA in common practice, as reflected in registries? (3) What is the survivorship free from revision of PFA and what are the reasons for and types of revisions? METHODS Data were provided by eight registries that are members of the International Society of Arthroplasty Registries (ISAR) who agreed to share ahe most common reason for revision across all countries was disease progression (42%, 434 of 1034). Most PFAs (83%, 810 of 980) were revised to a TKA. CONCLUSIONS The revision risk of PFA in all registries surveyed was more than three times higher than the reported revision risk of TKA at the same times. The survivorship of PFA is similar to that of the no-longer-used procedure of metal-on-metal conventional hip replacement. Although there may be potential functional benefits from PFA, these findings of consistent and alarmingly high rates of revision should create concern, particularly as this procedure is often used in younger patients. LEVEL OF EVIDENCE Level III, therapeutic study.BACKGROUND Lewinnek's recommendation for orienting the cup in THA is criticized because it involves a static assessment of the safe zone and because it does not consider stem geometry. A revised concept of the safe zone should consider those factors, but to our knowledge, this has not been assessed. QUESTIONS/PURPOSES (1) To determine the shape, size, and location of target zones for combined cup and stem orientation for a straight stem/hemispheric cup THA to maximize the impingement-free ROM and (2) To determine whether and how these implant positions change as stem anteversion, neck-shaft angle, prosthetic head size and target range of movements are varied. METHODS A three-dimensional computer-assisted design model, in which design geometry was expressed in terms of parameters, of a straight stem/hemispheric cup hip prosthesis was designed, its design parameters modified systematically, and each prosthesis model was implanted virtually at predefined component orientations. Functional component orientation ris study accurately defines the hypothetical impingement-free, design-specific component orientation in THA. Transforming it into clinical precision may be the case for navigation and/or robotics, but this is speculative, and as of now, unproven.BACKGROUND Ceramic bearings in THA have been used to reduce wear and, more recently, to avoid metals in the bearing because of the risk of metal ions adverse effects. Potential disadvantages to ceramic bearings are their brittleness and the ceramic fracture risk, which may lead to revision surgery. see more The frequency of revision for a fracture ceramic bearing, however, has not been thoroughly studied. QUESTIONS/PURPOSES (1) What is the frequency of revision for a fractured ceramic bearing in ceramic-on-polyethylene (CoP) and ceramic-on-ceramic (CoC) THAs, and is there any difference between alumina ceramics and alumina matrix composites (AMC)? (2) What are the factors associated with this complication? (3) To what extent did the patients who underwent revision for a fractured ceramic bearing undergo subsequent revisions, and for what reason? METHODS The Norwegian Arthroplasty Register has collected data on hip arthroplasty since 1987 and has a completeness of reporting of 97.3% for primary THAs and 93.3% for revisrticulations and in males. Bearings made of AMC appear to be at lower risk than those made from alumina ceramics. However, the long-term clinical wear performance of AMC bearings has not been extensively studied and should be studied further. LEVEL OF EVIDENCE Level III, therapeutic study.Tofacitinib is a novel oral janus kinase (JAK) inhibitor approved for the treatment of psoriatic arthritis. It was also investigated for the treatment of plaque psoriasis, although it is not approved by the Food and Drug Administration for this indication. This article aims to summarize the efficacy and safety data of tofacitinib for treatment of psoriatic disease. A comprehensive review of literature was conducted on the PubMed database using the search terms "((tofacitinib) AND (psoriasis)) OR ((tofacitinib) AND (psoriatic arthritis))". Data from the pivotal clinical trials evaluating tofacitinib in the treatment of psoriatic disease were summarized. The Oral-treatment Psoriasis Trial (OPT) study series demonstrated that tofacitinib is efficacious in the treatment of plaque psoriasis with an acceptable safety profile. The OPT studies also demonstrated the non-inferiority of tofacitinib 10mg twice daily compared to etanercept. The Oral Psoriatic Arthritis triaL (OPAL) study series demonstrated that tofacitinib significantly improved psoriatic arthritis outcomes compared to placebo and had an acceptable safety profile. Its efficacy is comparable to adalimumab in psoriatic arthritis. Patients treated with tofacitinib should be monitored for herpes zoster, malignancies, blood clots, and changes in laboratory values. Overall, tofacitinib is a useful new systemic agent in the treatment of psoriatic disease. Its oral route of administration, novel JAK pathway target, short half-life, and strong recapture rates after treatment interruption make it a unique new tool for psoriatic disease management. Further long-term studies will help determine its role in the treatment algorithm for psoriatic arthritis and its indication for plaque psoriasis.
