Anterior Cruciate

Background: Anterior cruciate ligament (ACL) ruptures are common, but the ideal timing for ACL reconstruction after injury is unclear with regard to meniscal insult. Purpose: To determine whether there is a relationship between timing from ACL rupture to ACL reconstruction and development of meniscal tears within this period. Study Design: Systematic review and meta-analysis. Methods: A systematic literature search was undertaken independently by 2 reviewers using the Cochrane method for systematic reviews in 5 online databases. The reviewers performed independent data extraction and assessment of risk of bias and study quality. The search included any comparative study, including randomized controlled trials (RCTs), prospective and retrospective cohort studies, and case-control studies of an adult population, that assessed the relationship between timing of ACL reconstruction surgery and rates of meniscal tears. Results: After screening, 12 studies (No. of participants = 3042) out of 3390 records were included for analysis: 3 RCTs (n = 272), 2 prospective cohort studies (n = 307), and 7 retrospective cohort studies (n = 2463). In analysis of these studies, rates of reported meniscal tears were compared for ACL procedures performed at 3 and 6 months after injury. Meta-analysis of 5 studies (n = 2012) showed that ACL reconstruction performed >3 months after injury was associated with a higher rate of medial meniscal tears compared with ACL reconstruction performed within 3 months of injury (estimated OR, 2.235; 95% CI, 1.183-4.223; P = .013) but not with a higher rate of lateral meniscal tears. Similarly, meta-analysis of 4 studies (n = 990) showed that ACL reconstruction performed >6 months after injury was associated with a higher rate of medial meniscal tears compared with ACL reconstruction performed within 6 months of injury (estimated OR, 2.487; 95% CI, 1.241-4.984; P = .01) but not with a higher rate of lateral meniscal tears. Conclusion: Our results suggest that delay of ACL reconstruction surgery >3 months after injury is associated with a higher rate of medial meniscal tears within this prereconstruction time frame. Further high-quality prospective studies may help determine whether this is a causal effect. However, based on current evidence, in those patients for whom ACL reconstruction is indicated, ACL reconstruction within 3 months of injury may be recommended.

Background: After anterior cruciate ligament (ACL) injury, the optimal timing of ACL reconstruction and the influence of this timing on chondral damage remain unclear. Purpose: To assess the effect of timing of ACL reconstruction on the presence of chondral injuries via a systematic review and meta-analysis. Study Design: Systematic review and meta-analysis; Level of evidence, 4. Methods: Two reviewers independently performed systematic literature searches of 5 online databases using the Cochrane methodology for systematic reviews. Eligibility criteria were any comparative study of patients aged >16 years that assessed the relationship between timing of primary ACL reconstruction surgery and rates of chondral injuries. Meta-analysis was conducted using a random-effects model. Results: After screening, 14 studies (n = 3559 patients) out of 2363 titles met the inclusion criteria: 3 randomized controlled trials (n = 272), 3 prospective cohort studies (n = 398), and 8 retrospective cohort studies (n = 2889). In analysis of the studies, chondral injury rates were compared between ACL reconstructions performed before and after 3 time points: 3, 6, and 12 months after injury (eg, ≤3 vs >3 months). The rates of chondral injury increased with each time point. The increase was mostly due to low-grade injuries at 3 months (estimated odds ratio, 1.914; 95% CI, 1.242-2.949; P = .003), with the increase in high-grade injuries becoming predominant after 12 months (estimated odds ratio, 3.057; 95% CI, 1.460-6.40; P = .003). Conclusion: Our findings suggest that delaying ACL reconstruction surgery results in a higher rate of chondral injuries and the severity of these lesions worsens with time. These findings are comparable with those of our previously published study, which demonstrated a higher risk of meniscal tears associated with delayed ACL surgery. When ACL reconstruction is indicated, surgery ≤3 months after injury is associated with a lower risk of intra-articular damage. Registration: CRD42016032846 (PROSPERO).

Objective To investigate the relationship between maternal exposure to alcohol and low birthweight (LBW). Methods The literature search was performed in January 2017 using the following electronic databases: Medline, Embase, LILACS, SciELO, Web of Science, Scopus, CINHAL, Proquest, and PsychInfo. The search strategy used the following terms: alcohol drinking, binge drinking, alcohol-related disorders, alcoholism, alcohol addiction/use/abuse/consumption, light/moderate/social/low drinking, low birthweight, case-control studies, retrospective studies, and cohort studies. No restrictions regarding language or publication date were considered. The literature search yielded 2,383 articles, and after screening and eligibility assessment, 39 articles were included in the systematic review, and 38 studies were included in the meta-analysis. Results Maternal alcohol consumption was associated with LBW among retrospective cohort studies (relative risk [RR] = 1.37; 95%CI [confidence interval]:1.10–1.77; I2 = 98.4%; p < 0.01). Prospective cohort studies (RR = 1.11; 95%CI: 0.98–1.25; I2 = 81.5%; p < 0.01), and case-control studies (odds ration [OR] = 1.16; 95%CI: 0.68–1.97; I2 = 61.2%; p = 0.05) showed no association between alcohol and LBW. No publication bias was identified, and the meta-regression showed that the sample size influenced the high heterogeneity among retrospective cohort studies. The subgroup analysis showed differences in association between groups when compared by sample size, type of adjustment, or crude measures and publication year. Conclusions We have not found an association between alcohol consumption during gestation and LBW in the analysis in all of the subgroups. In addition, we have found a high heterogeneity between the primary studies, which is related to methodological differences in the conduction of these studies.

ObjectivesTo analyse the relationship between serum uric acid (SUA), all-cause and cardiovascular (CV) mortality in peritoneal dialysis (PD) patients to inform clinical practice and future research.DesignA systematic review of observational studies.Data sourcesPubMed, Embase, Web of Science, the Cochrane Library, China National Knowledge Infrastructure (CNKI), SinoMed, Chinese Science and Technology Journal Database (VIP) and Wan Fang databases were searched from their inception to January 2021 for cohort and case–control studies reporting SUA and mortality in patients with PD.MethodsThe Newcastle-Ottawa Quality Assessment Scale was used to appraise quality of cohort and case–control studies. Effect estimates were presented as HRs with 95% CIs in a meta-analysis using STATA V.16.0. Data not suitable for pooling were synthesised qualitatively.ResultsFourteen cohort studies with 24 022 patients were included. No case–control studies were identified. For prospective cohort studies, pooled results for the highest SUA category were significantly greater than the lowest for all-cause (one study; 1278participants; HR 1.79; 95% CI 1.17 to 2.75) and CV mortality (one study; 1278 participants; HR 2.63; 1.62–4.27). An increase of 1 mg/dL in SUA level was associated with a 16% increased risk of all-cause mortality (one study; 1278 participants; HR 1.16; 1.03–1.32) and 34% increased CV mortality risk (one study; 1278 participants; HR 1.34; 1.16–1.55). For retrospective cohort studies, the highest SUA category did not demonstrate an elevated all-cause (five studies; 4570 participants; HR 1.09; 0.70–1.70) or CV mortality (three studies; 3748 participants; HR 1.00; 0.44–2.31) compared with the lowest SUA category. Additionally, there was no increase in all-cause (eight studies; 11 541 participants; HR 0.94; 0.88–1.02) or CV mortality (three studies; 7427 participants; HR 0.90; 0.76–1.06) for every 1 mg/dL increase in SUA level.ConclusionsResults of prospective and retrospective cohort studies were inconsistent. Consequently, prospective, multicentre, long-term follow-up studies are required to confirm the relationship between SUA and mortality in patients with PD.

IntroductionInjuries of the anterior cruciate ligament (ACL) are a common musculoskeletal complication and can cause significant reduction in patient function and quality of life. Many undergo ACL reconstruction, with high-quality rehabilitation key to successful outcome. Knowledge of physical prognostic factors, such as quadriceps strength, is crucial to inform rehabilitation and has important implications for outcome following ACL reconstruction. However, these factors predicting outcome are poorly defined. Therefore, the aim of this systematic review is to establish physical prognostic factors predictive of outcome in adults following ACL reconstruction. Outcome will be subdivided into two groups of outcome measures, patient-reported and performance-based. Physical prognostic factors of interest will reflect a range of domains and may be modifiable/non-modifiable. Results will help decide most appropriate management and assist in planning and tailoring preoperative and postoperative rehabilitation.Methods and analysisThis systematic review protocol is reported according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. MEDLINE, CINAHL and EMBASE databases, key journals and grey literature will be searched from inception to July 2019. Prospective cohort studies including participants aged ≥16 years who have undergone ACL reconstruction will be included, with articles focusing on multi-ligament reconstructions and ACL repair surgery, or not published in English excluded. Two independent reviewers will conduct searches, assess study eligibility, extract data, assess risk of bias (Quality in Prognostic Studies tool) and quantify overall quality of evidence (modified Grading of Recommendations, Assessment, Development and Evaluation guidelines). If possible, a meta-analysis will be conducted, otherwise a narrative synthesis will ensue focusing on prognostic factors, risk of bias of included studies and strength of association with outcomes.Ethics and disseminationFindings will be published in a peer-reviewed journal, presented at conferences and locally to physiotherapy departments. Ethical approval is not required for this systematic review.PROSPERO registration numberCRD42019127732.

Background: Vancomycin presoaking of the graft has been shown to decrease infection rates in some case series of anterior cruciate ligament (ACL) reconstruction. Purpose: We sought to substantiate the efficacy of vancomycin presoaked grafts for the prevention of infection after ACL reconstruction. Methods: We performed a systematic review of Medline and OVID to assess the incidence of postoperative infection in studies comparing patients undergoing ACL reconstruction with the use of vancomycin presoaked ACL grafts and a control group of patients undergoing ACL reconstruction without the use of presoaked grafts. The efficacy of vancomycin presoaking was calculated using the Agresti-Coull confidence interval. Relative risk (RR) was calculated for every study and the total sample. Results: The 11 studies that met inclusion criteria comprised 24,298 patients. In patients with vancomycin presoaking of the graft, 1 infection was reported in 8764 cases (0.01% rate). In the studies with control groups that did not have vancomycin presoaked grafts, there were 125 infections in 15,534 ACL reconstructions (0.8% rate). The efficacy of vancomycin presoaking in preventing infection after ACL reconstruction was 99.9% (0.999%–1.000% CI). The overall RR obtained was 0.07 (0.03–0.16 CI). All included studies were retrospective cohort studies (level III). Conclusions: Vancomycin presoaking of the graft has been shown to decrease infection rates after ACL reconstruction in studies of low evidence level. This suggests the need for prospective randomized controlled trials addressing this issue so that recommendations on the routine use of vancomycin presoaking of ACL grafts can be made with confidence.
