MUA within 1 year was recorded in 6882 patients (2.22%; 95% confidence interval [95% CI], 2.17-2.28) defining the MUA cohort; all others were included in the parallel non-MUA cohort. At 6 years, the mortality-adjusted estimated implant survival rate in the MUA cohort was 91.2% (95% CI, 90.0-92.2) in comparison to 98.1% (95% CI, 98.0-98.2) in the non-MUA cohort. In the fully adjusted model, this corresponded to an adjusted hazard for revision of 5.03 (hazard ratio; 95% CI, 4.55-5.57). Conclusion Patients who underwent MUA within 1 year of primary arthroplasty were at a 5-fold increased risk of subsequent revision even after excluding cases of infection or fracture. Further investigation of the etiology of stiffness after primary knee arthroplasty and the optimal treatment options to improve outcomes is justified.Background We compared the revision risk between metal-on-polyethylene (MOP) and ceramic-on-polyethylene (COP) total hip arthroplasty patients and evaluated temporal changes in short-term revision risks for MOP patients. Methods Primary MOP (n = 9480) and COP (n = 3620) total hip arthroplasties were evaluated from the Medicare data set (October 2005 to December 2015) for revision risk, with up to 10 years of follow-up using multivariate analysis. Temporal change in the short-term revision risk for MOP was evaluated (log-rank and Wilcoxon tests). Results Revision incidence was 3.8% for COP and 4.3% for MOP. MOP short-term revision risk did not change over time (P ≥ .844 at 1 year and .627 at 2 years). Dislocation was the most common reason for revision (MOP 23.5%; COP 24.8%). Overall adjusted revision risks were not different between MOP and COP up to 10 years of follow-up (P ≥ .181). Conclusions Concerns with corrosion for metal heads do not appear to result in significantly elevated revision risk for MOP at up to 10 years. Corrosion does not appear as a primary reason for revision compared to other mechanisms.Background Although the influence of psychological distress on the outcomes of total knee arthroplasty has been described extensively, its effect on unicompartmental knee arthroplasty (UKA) is poorly defined. Furthermore, most studies in arthroplasty literature had short follow-ups of ≤1 year. We investigated the influence of psychological distress on long-term patient-reported outcomes and analyzed the change in mental health after UKA in a cohort with minimum 10 years of follow-up. Methods Prospectively collected data of 269 patients undergoing UKA in 2004-2007 were reviewed. Patients were stratified into those with psychological distress (36-item Short-Form health survey [SF-36] Mental Component Summary [MCS] less then 50, n = 111) and those without (SF-36 MCS ≥50, n = 158). Clinical outcomes were obtained preoperatively, at 2 years, and 10 years. Multiple regression was used to control for age, gender, body mass index, Charlson Comorbidity Index, American Society of Anesthesiologists class, and baseline scores. selleck products The rate of expectation fulfillment and satisfaction was compared. Results Psychologically distressed patients had poorer Knee Society Knee Score, Function Score, Oxford Knee Score, and SF-36 Physical Component Summary preoperatively, at 2 years, and 10 years. However, an equal proportion in each group attained the minimal clinically important difference for each score. Distressed patients had a comparable rate of satisfaction (91% vs 95%, P = .136) but lower fulfillment of expectations (89% vs 95%, P = .048). The percentage of distressed patients declined from 41% to 35% at follow-up. The mean SF-36 MCS improved by 6.9 points. Conclusion Although psychologically distressed patients had relatively greater pain and poorer function preoperatively and up to 10 years after UKA, a similar proportion of them experienced a clinically meaningful improvement in patient-reported outcomes.Background The transition to motherhood is an exciting yet challenging period that requires physical, emotional, and social adjustment. During the postpartum period, mothers require support and information to ensure a smooth transition and adjustment to motherhood. One innovative strategy to provide mothers with this information is mobile health (mHealth), and specifically, text messaging. Objective To describe the design, development and usability testing of a postnatal text message intervention called Essential Coaching for Every Mother. Methods First time mothers (n=11) and postpartum healthcare providers (n=18) were involved in iterative interviewing in Halifax, Canada. Adaption of content occurred through three rounds of user testing using semi-structured interviews. The Information Assessment Method (IAM) Parents survey was also completed by mothers. Results Three cycles of iterative testing were conducted with eight participants (3 mothers, 5 healthcare providers), thirteen participants (8 mothers, 5 healthcare providers) and 8 participants (8 healthcare providers), respectively. Messages evolved from risk-focused to prevention and education focused. Mothers felt the messages addressed their needs and healthcare providers ensured the content was consistent with the messaging currently provided to postpartum mothers. Conclusion Essential Coaching for Every Mother is the first postnatal educational text message intervention developed for mothers in Halifax, Canada. We sought to involve first time mothers (end-users) and postpartum healthcare providers (experts) in the development and usability evaluation to ensure the intervention adequately met needs and was consistent with current practices related to postpartum education.Objectives Gradual-onset injuries associated with surfing have not previously been closely examined. This study investigated the duration, mechanisms, body locations and types of gradual-onset injuries in a sample of New Zealand surfers. Design Retrospective, cross-sectional online survey. Methods Self-identified surfers reported gradual-onset surfing-related injuries experienced in the preceding 12 months. Results Respondents (n=1473, age range 8-74 years) reported a total of 550 gradual-onset major injuries 44% acute duration ( less then 3 months) and 56% chronic (≥3 months). The injury incidence proportion was 27%. Shoulder (146 injuries, 64% chronic), low back (115 injuries, 58% chronic) and neck (105 injuries, 46% chronic) were the most commonly reported injury locations. Prolonged paddling was the most commonly reported mechanism of injury (40% of all injuries). Incidence proportion for gradual-onset major injuries was 6% higher for greater surfing abilities compared to lower abilities (p=0.01), and 13% higher for long boarders compared to short boarders (p=0.
