:Background and purpose - Both medial unicompartmental knee arthroplasties (UKA) and high tibial osteotomies (HTO) are reliable treatments for isolated medial knee osteoarthritis. However, both may with time need conversion to a total knee arthroplasty (TKA). We conducted the largest nationwide registry comparison of the survival of TKA following UKA with TKA following HTO.Patients and methods - From the Danish Knee Arthroplasty Registry, aseptic conversions to TKA from UKA and TKA converted from HTO within the period of 1997-2018 were retrieved. The Kaplan-Meier method and the Cox proportional hazards regression were used to estimate the survival and hazard ratio (HR) for revision, considering confounding by indication utilizing propensity-score based inverse probability of treatment weighting (PS-IPTW).Results - PS-IPTW yielded a well-balanced pseudo-cohort (standard mean difference (SMD) < 0.1 for all covariates, except implant supplementation) of 963.8 TKAs following UKA and 1139.1 TKAs following HTO. The survival of TKA following UKA was significantly less than that of TKA following HTO with a 5-year estimated survival of 0.88 (95% confidence interval (CI) 0.85-0.90) and 0.94 (CI 0.93-0.96), respectively. The differences in survival corresponded to an implant-supplementation adjusted HR of 2.7 (CI 2.4-3.1) for TKA following UKA compared with TKA following HTO.Interpretation - Previous UKA more than doubled the revision risk of a subsequent TKA compared with previous HTO. This potential risk should be considered in the shared treatment decision of patients who are candidates for both UKA and HTO.


背景和目的: 内侧单髁膝关节成形术 (UKA) 和胫骨高位截骨术 (HTO) 都是孤立性内侧膝骨关节炎的可靠治疗方法。然而,两者都可能随着时间的推移需要转为全膝关节置换术 (TKA)。我们对UKA后TKA与HTO后TKA的生存率进行了最大规模的全国注册比较。患者和方法-从丹麦膝关节置换术登记处检索到 1997-2018 期间从UKA无菌转换为TKA,从HTO转换为TKA。使用Kaplan-Meier方法和Cox比例风险回归估计生存和风险比 (HR) 进行翻修,考虑使用基于倾向评分的治疗加权逆概率 (PS-IPTW) 的适应症的混杂。结果-PS-IPTW产生了一个平衡良好的伪队列 (所有协变量的标准平均差 (SMD) <0.1,除植入物补充外) UKA后 963.8 TKAs和HTO后 1139.1 TKAs。UKA术后TKA的生存率明显低于HTO术后TKA的生存率,5 年估计生存率为 0.88 (95% 置信区间 (CI) 0.85-0.90) 和 0.94 (CI 0.93-0.96)。存活率的差异对应于UKA术后TKA与HTO术后TKA的植入物补充调整HR为 2.7 (CI 2.4-3.1)。解释-以前的UKA与以前的HTO相比,随后的TKA的修订风险增加了一倍多。这种潜在的风险应该在UKA和HTO候选患者的共同治疗决策中考虑。

METHODS:OBJECTIVE:Patients with immune-mediated inflammatory diseases such as rheumatoid arthritis or systemic lupus erythematosus are at increased risk of cardiovascular disease. However, the cardiovascular risk of patients with primary Sjögren's syndrome (SS) remains poorly studied. We aimed to investigate the association between primary SS and cardiovascular morbidity and mortality. METHODS:We performed a systematic review of articles in Medline and the Cochrane Library and recent abstracts from US and European meetings, searching for reports of randomized controlled studies of cardiovascular morbidity and cardiovascular mortality in primary SS. The relative risk (RR) values for cardiovascular morbidity and mortality associated with primary SS were collected and pooled in a meta-analysis with a random-effects model by using Review Manager (Cochrane collaboration). RESULTS:The literature search revealed 484 articles and abstracts of interest; 14 studies (67,124 patients with primary SS) were included in the meta-analysis. With primary SS versus control populations, the risk was significantly increased for coronary morbidity (RR 1.34 [95% confidence interval (95% CI) 1.06-1.38]; P = 0.01), cerebrovascular morbidity (RR 1.46 [95% CI 1.43-1.49]; P < 0.00001), heart failure rate (odds ratio 2.54 [95% CI 1.30-4.97]; P < 0.007), and thromboembolic morbidity (RR 1.78 [95% CI 1.41-2.25]; P < 0.00001), with no statistically significant increased risk of cardiovascular mortality (RR 1.48 [95% CI 0.77-2.85]; P = 0.24). CONCLUSION:This meta-analysis demonstrates that primary SS is associated with increased cardiovascular morbidity, which suggests that these patients should be screened for cardiovascular comorbidities and considered for preventive interventions, in a multidisciplinary approach with cardiologists.

METHODS:OBJECTIVE:We aimed to evaluate the comparative risk of hospitalized infection among patients with rheumatoid arthritis (RA) who initiated abatacept versus a tumor necrosis factor inhibitor (TNFi). METHODS:Using claims data from Truven MarketScan database (2006-2015), we identified patients with RA ages ≥18 years with ≥2 RA diagnoses who initiated treatment with abatacept or a TNFi. The primary outcome was a composite end point of any hospitalized infection. Secondary outcomes included bacterial infection, herpes zoster, and infections affecting different organ systems. We performed 1:1 propensity score (PS) matching between the groups in order to control for baseline confounders. We estimated incidence rates (IRs) and hazard ratios (HRs) with 95% confidence intervals (95% CIs) for hospitalized infection. RESULTS:We identified 11,248 PS-matched pairs of patients who initiated treatment with abatacept and TNFi with a median age of 56 years (83% were women). The IR per 1,000 person-years for any hospitalized infection was 37 among patients who initiated treatment with abatacept and 47 in those who initiated treatment with TNFi. The HR for the risk of any hospitalized infection associated with abatacept versus TNFi was 0.78 (95% CI 0.64-0.95) and remained lower when compared to infliximab (HR 0.63 [95% CI 0.47-0.85]), while no significant difference was seen when compared to adalimumab and etanercept. The risk of secondary outcomes was lower for abatacept for pulmonary infections, and similar to TNFi for the remaining outcomes. CONCLUSION:In this large cohort of patients with RA who initiated treatment with abatacept or TNFi as a first- or second-line biologic agent, we found a lower risk of hospitalized infection after initiating abatacept versus TNFi, which was driven mostly by infliximab.

METHODS:OBJECTIVE:Reducing pain is one of the main health priorities for children and young people with juvenile idiopathic arthritis (JIA); however, some studies indicate that pain is not routinely assessed in this patient group. The aim of this study was to explore health care professionals' (HCPs) beliefs about the role of pain and the prioritization of its assessment in children and young people with JIA. METHODS:Semi-structured interviews were conducted with HCPs who manage children and young people with JIA in the UK (including consultant and trainee pediatric rheumatologists, nurses, physical therapists, and occupational therapists). Data were analyzed qualitatively following a framework analysis approach. RESULTS:Twenty-one HCPs participated. Analyses of the data identified 6 themes, including lack of training and low confidence in pain assessment, reluctance to engage in pain discussions, low prioritization of pain assessment, specific beliefs about the nature of pain in JIA, treatment of pain in JIA, and undervaluing pain reports. Assessment of pain symptoms was regarded as a low priority and some HCPs actively avoided conversations about pain. CONCLUSION:These findings indicate that the assessment of pain in children and young people with JIA may be limited by knowledge, skills, and attitudinal factors. HCPs' accounts of their beliefs about pain in JIA and their low prioritization of pain in clinical practice suggest that a shift in perceptions about pain management may be helpful for professionals managing children and young people with this condition.
