Abstract Objective The purpose of this study was to perform a meta-analysis comparing mobile-bearing with fixed-bearing total knee arthroplasty (TKA) in terms of all-cause revision rates, aspetic loosening, knee functional scores, range of motion and radiographic lucent lines and osteolysis. Methods PubMed, Cochrane Library, Google Scholar and Web of Science were searched up to January 2020. Randomized controlled trials that compared primary mobile-bearing with fixed-bearing TKA, reporting at least one of the outcomes of interest, at a minimum follow-up of 12 months were included. All outcomes of interest were pooled at short-term (< 5 years), mid-term (5 to 9 years) and long-term (> = 10 years) follow-up intervals. Results A total of 70 eligible articles were included in the qualitative and statistical analyses. There was no difference between mobile-bearing or fixed-bearing TKA at short-term, mid-term and long-term follow-ups in all outcome measures including all-cause revision rate, aseptic loosening, oxford knee score, knee society score, Hospital for Special Surgery score, maximum knee flexion, radiographic lucent lines and radiographic osteolysis. Conclusion The current level of evidence demonstrated that both mobile-bearing and fixed-bearing designs achieved excellent outcomes, yet it does not prove the theoretical advantages of the mobile-bearing insert over its fixed-bearing counterpart. The use of either design could therefore be supported based on the outcomes assessed in this study. Level of Evidence: Level II, Therapeutic

Background:Knee osteoarthritis (OA) is a frequent degenerative disease representing an important health and economic burden. Symptomatic medical treatments available include intra-articular (IA) injections of corticosteroids (GC) but their efficacy is debated. In addition, safety signals regarding cartilage damage with IA GC have been highlighted in a few studies.Objectives:To perform a meta-analysis of studies assessing IA GC efficacy and safety in knee OA.Methods:A systematic literature review and a meta-analysis of randomized controlled trials (RCTs) assessing the effect of GC IA injections versus other interventions (IA Hyaluronic Acid, IA placebo, IA NSAID, oral NSAID or physiotherapy) in knee OA was performed. The effect of the interventions on pain and function were extracted from the single studies and pooled and are presented as short term (<6weeks), medium term (6-24 weeks) and long term (>24 weeks) follow-up period. Standardized mean differences (SMD) are reported.Results:Of 520 studies screened, 23 were included in the SLR and 14 subsequently included in the MA. While IA GC showed a superior effect compared to control on both pain (SMD -0.61 (95% CI -1,25, 0.03)) and function (SMD -1.02 (95% CI -2.14, 0.10)) in short term follow-up; long term follow-up analysis favored controls (IA HA, IA NSAID, physiotherapy) for both pain (SMD 0.68 (95% CI -0.11, 1.47)) and function (SMD 0.88 (95% CI -0.36, 2.12) outcomes (Figure 1). No difference was found between interventions in the medium term. Safety data were reported in 18/23 studies (n= 1936/2314 patients); and side effects were reported as follows: arthralgia (69 IA GC patients, 146 IA HA patients, and 20 saline patients); site injection pain (7 in the IA GC group, 2 in the IA saline group, 14 in the IA HA group); 16 post injection knee swelling without signs of septic arthritis in the IA GC group and 24 in the IA HA group. In one study assessing cartilage effects of GCs, the rate of cartilage loss was greater in the GC group with a reduction of cartilage thickness at 2 year compared to placebo group. No difference was observed in the progression of cartilage denudation or bone marrow lesion. On the contrary, another study showed no effect of injections on the cartilage structure.Conclusion:We demonstrate in this work that IA GC injections reduce pain and improve function in the early phase (≤6 weeks) of treatment. In the long term (≥24 weeks), other intervention such as IA HA injections or physiotherapy seem to be more efficient, but this effect was largely driven by single studies with large effect sizes and the comparators were heterogeneous.Figure 1.Knee pain outcome at short term (≤6weeks) (A), medium term (>6 & <24 weeks) (B), and long term (≥24 weeks) (C) follow up.Disclosure of Interests:None declared.

AbstractThis meta-analysis aimed to compare the clinical and radiographic outcomes between mobile-bearing total knee arthroplasty (MB-TKA) and fixed-bearing total knee arthroplasty (FB-TKA) at a minimum 10-year follow-up. PubMed, EMBASE, and Cochrane databases were searched. All included articles were evaluated by two trained reviewers according to the guidelines of the Cochrane Collaboration Handbook for potential risk, and the Consolidated Standards on Reporting Trials (CONSORT) checklist and scoring system was also used to assess the methodological quality of each study. The extracted data included function scores, range of motion (ROM) of the knee, incidence of adverse events or revision, survivorship analysis, and radiographic outcomes. Seven randomized controlled trials (RCTs) were included in this meta-analysis, and all RCTs had a follow-up period longer than 10 years. This meta-analysis shows no significant difference between the two groups with respect to the Keen Society Score (KSS; p = 0.38), KSS function score (p = 0.30), the Western Ontario and McMaster Universities Osteoarthritis index (WOMAC; p = 0.59), ROM (p = 0.71), radiolucent line (p = 0.45), femoral and tibial component positions in the coronal plane (p = 0.55 and 0.35, respectively), revision incidence (p = 0.77), and survivorship rates (p = 0.39). Meanwhile, it showed a slight difference between the two groups in the tibial component position in the sagittal plane (p = 0.003). According to this meta-analysis, the current best available evidence suggests no significant difference between the MB-TKA and FB-TKA groups with respect to the clinical outcomes, radiographic outcomes, revision, and survivorship at a minimum 10-year follow-up. This is a Level II, meta-analysis study.

AbstractChildren with parents suffering from a psychiatric disorder are at higher risk for developing a mental disorder themselves. This systematic review and meta-analysis of randomized controlled trials aims to evaluate the efficacy of psychosocial interventions to prevent negative mental health outcomes in the offspring of parents with mental illness. Eight electronic databases, grey literature and a journal hand-search identified 14 095 randomized controlled trials with no backward limit to June 2021. Outcomes in children included incidence of mental disorders (same or different from parental ones) and internalizing and externalizing symptoms at post-test, short-term and long-term follow-up. Relative risks and standardized mean differences (SMD) for symptom severity were generated using random-effect meta-analyses. Twenty trials were selected (pooled n = 2689 children). The main therapeutic approaches found were cognitive-behavioural therapy and psychoeducation. A significant effect of interventions on the incidence of mental disorders in children was found with a risk reduction of almost 50% [combined relative risk = 0.53, 95% confidence interval (CI) 0.34–0.84]. Interventions also had a small but significant effect on internalizing symptoms at post-test (SMD = −0.25, 95% CI −0.37 to −0.14) and short-term follow-up (−0.20, 95% CI −0.37 to −0.03). For externalizing symptoms, a decreasing slope was observed at post-test follow-up, without reaching the significance level (−0.11, 95% CI −0.27 to 0.04). Preventive interventions targeting the offspring of parents with mental disorders showed not only a significant reduction of the incidence of mental illness in children, but also a diminution of internalizing symptoms in the year following the intervention.

Abstract Background To determine the long-term effects (a minimum follow-up time 8.8 years) of cemented and cementless fixations used for total knee arthroplasty (TKA). Methods PubMed, EMBASE, Ovid, Cochrane Library, CINAHL, China National Knowledge Infrastructure and China Wangfang database were interrogated for appropriate randomized controlled trials (RCTs) through July 2020. Data were extracted and assessed for accuracy by 2 of the authors acting independently. Any controversial discrepancies were resolved after discussion with a third author. Result Eight RCTs were included with low to moderate bias risks. The cemented fixation of TKA was comparable to cementless fixation in terms of implant survival (relative risk, 1.016; 95% CI 0.978 to 1.056; P = 0.417), Knee Society (KS) knee score (standardized mean difference (SMD), − 0.107; 95% CI − 0.259 to 0.045; P = 0.168), KS function score (SMD − 0.065; 95% CI − 0.238 to 0.109; P = 0.463), KS pain score (SMD − 0.300; 95% CI − 0.641 to 0.042; P = 0.085), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score (SMD − 0.117; 95% CI − 0.307 to 0.073; P = 0.227), HSS score (SMD − 0.027; 95% CI − 0.270 to 0.217; P = 0.829), range of motion (SMD 0.061; 95% CI − 0.205 to 0.327; P = 0.652) at ≥ 8.8 years of follow-up. In terms of radiographic outcomes at ≥ 8.8 years of follow-up, the incidence of a radiolucent line in the cementless group was lower than for the cemented group (SMD 3.828; 95% CI 2.228 to 6.576; P < 0.001). However, the maximum total point motion (MTPM) of the cementless group was greater than for the cemented group (SMD − 0.739; 95% CI − 1.474 to − 0.005; P = 0.048). Conclusions Long-term follow-up verified that cementless and cemented fixation have similar prosthesis survival rates, clinical scores and mobility. However, radiography suggested that each technique had an advantage with regard to the radiolucent line and MTPM.

Introduction: Female sexual dysfunction is a common problem, affecting more than 1/3 of women during their lives. The aim of this review is to review the evidence for the effectiveness of testosterone in sexual dysfunction in postmenopausal women, particularly in the improvement of sexual desire.Material and Methods: The authors searched in international databases National Guidelines Clearinghouse, Guidelines Finder, Cochrane Library and MEDLINE/PubMed, for guidelines, systematic reviews, meta-analysis and randomized controlled trials, published between January 2005 and February 2017, using the MeSH terms ‘testosterone’, ‘androgens’, ‘libido’, ‘sexual dysfunctions’ and ‘menopause’.Results: From a pool of 506 articles, 11 were selected: three guidelines, one systematic review with meta-analysis and seven randomized controlled trials. The selected articles showed testosterone‘s efficacy on global sexual function and improvement of sexual desire in postmenopausal women, when both are used in monotherapy or in association with other hormones. No study showed changes in hepatic enzymes or serious adverse effects.Discussion: The small sample size and short follow-up used in the included studies limits the ability to assess testosterone’s long-term benefits and effects.Conclusion: At short-term, testosterone seems to improve sexual function in postmenopausal women, particularly sexual desire. Nevertheless, more studies with larger sample size and longer follow-up are needed to understand its long-term safety and effectiveness.

Background: Depression is a major nonmotor symptom of Parkinson’s disease (PD). However, few treatments exist for PD depression. Monoamine oxidase-B inhibitors (MAOB-Is) provide symptomatic relief for the motor symptoms of PD and exert antidepressive effects. The present meta-analysis of randomized controlled trials (RCTs) investigated the effects of MAOB-Is on depressive symptoms in patients with PD. Methods: Articles on PD-management-related RCTs using one of three MAOB-Is approved by the US Food and Drug Administration, that is, selegiline, rasagiline, and safinamide, were identified. The primary outcomes were the benefits of MAOB-Is for depressive symptoms. Subgroup analysis included the effects of MAOB-Is on patients in the early versus middle-to-late stages of PD and the effect of short-term versus long-term treatment. Results: Overall, six studies were included, four of which were conducted on patients with early stage PD. Overall, MAOB-Is significantly reduced the severity of depressive symptoms [standardized mean difference (SMD): −0.14, 95% confidence interval (CI): −0.21 to −0.06, p < 0.001]. Subgroup analysis indicated that the positive effect of MAOB-Is was significant in patients with early stage PD (SMD: −0.20, 95% CI: −0.31 to −0.09, p < 0.001), but not in those with middle-to-late-stage PD (SMD: −0.07, 95% CI: −0.17 to 0.03, p = 0.18). The antidepressive effect was significant for short-term treatment, that is, 90–120 days (SMD: −0.23, 95% CI: −0.35 to −0.10, p < 0.001), but not long-term treatment, that is, 24 weeks to 18 months (SMD: −0.08, 95% CI: −0.18 to 0.01, p = 0.09). Conclusion: In addition to the treatment of PD motor symptoms, MAOB-Is may help reduce the severity of depressive symptoms in PD, especially in patients with early stage PD. Considering the tolerability and simultaneous benefits of MAOB-Is, further RCTs are warranted to confirm their therapeutic effects in moderate-to-severe PD depression.

AbstractAs more patients undergo total knee arthroplasty (TKA) each year, and the average age of patients gets younger, the patients are generally more active requiring a greater physiological demand and increasing range of motion on the prosthesis than the previous patients. However, there is no consensus on the optimal TKA tibial bearing design. We performed this systematic review to compare the clinical differences between mobile and fixed bearing constructs used in contemporary TKA. We searched PubMed, EMBASE, and Cochrane Library databases, identifying 515 total publications, including 17 randomized controlled trials (RCTs). A meta-analysis was performed, while the quality and bias of the evidence were rated according to the Grading of Recommendations Assessment Development and Evaluation (GRADE) guidelines and the Cochrane Database questionnaire. The meta-analysis was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Seventeen studies were included, with a total of 1505 knees receiving a mobile bearing TKA and 1550 knees receiving a fixed bearing TKA. The meta-analysis compared clinical outcomes between mobile bearing (MB)-TKA and fixed bearing (FB)-TKA using postoperative Knee Society Score, postoperative ROM, and survivorship and showed that there was a distinct difference in Knee Society Score between the mobile-bearing and fixed-bearing groups (overall standardized mean difference = 1.38; 95% confidence interval (CI): 0.50–2.25; p = 0.002; I2 = 60%). Patients treated with mobile-bearing prostheses were more likely to report good or excellent range of motion results (overall standardized mean difference = 2.06; 95% CI: 0.65–3.47; p = 0.004). No difference in implant survivorship or reoperation rate were identified. The fixed-bearing and mobile-bearing TKA designs are both capable of producing excellent long-term results with excellent clinical outcomes if properly implanted; however, the mobile-bearing TKA have superiority in mid- to long-term clinical results. Trial registration number for PROSPERO was CRD42019126402.
