Background Arthroscopic reconstruction for anterior cruciate ligament rupture is a common orthopaedic procedure. One area of controversy is whether the method of double-bundle reconstruction, which represents the 'more anatomical' approach, gives improved outcomes compared with the more traditional single-bundle reconstruction. Objectives To assess the effects of double-bundle versus single-bundle for anterior cruciate ligament reconstruction in adults with anterior cruciate ligament deficiency.
Surgical management is recommended for unstable distal clavicle fractures. A variety of methods have been previously reported, but there is no current consensus regarding which method is most suitable. Therefore, we have conducted a systematic review and network meta-analysis to compare postoperative shoulder function and complications between different fixation methods to identify which class of fixation is best for unstable distal clavicle fractures. We searched the literature systematically using eligibility criteria of all comparative studies that compared postoperative outcomes of coracoclavicular fixation (tight rope, screw or endobutton), hook plating, plate and screws, tension band wiring and transacromial pinning fixation for unstable distal clavicle fractures from PubMed, EMBASE, and Scopus databases up to February 10, 2018. Two reviewers independently extracted data. A network meta-analysis was applied to combine direct and indirect evidence and to estimate the relative effects of the treatment options. The probability of being the best treatment was estimated using surface under the cumulative ranking curves (SUCRA). Ten comparative studies (n = 505 patients) with one RCT study (n = 42) met the inclusion criteria. Intervention included coracoclavicular fixation (n = 111 patients), hook plating (n = 300 patients), plate and screws (n = 41 patients), tension band wiring (n = 81 patients) and transacromial pinning (n = 14 patients). A network meta-analysis showed that CM scores of coracoclavicular fixation were significantly higher when compared to hook plate and tension band wiring, with pooled mean of 2.98 (95% CI 0.05-5.91) and 7.11 (95% CI 3.04-11.18). For UCLA, CC fixation and plate and screw fixation had significantly higher scores compared to hook plating fixation with a mean score 2.22 (95% CI 0.44-3.99) and 3.20 (95% CI 0.28-6.12), respectively. In terms of complications, plate and screw fixation had lower risk with RRs of 0.63 (95% CI 0.20-1.98), 0.37 (95% CI 0.19-0.72), 0.11 (95% CI 0.04-0.30) and 0.02 (95% CI 0.002-0.16) when compared to coracoclavicular fixation, hook plating, tension band wiring and transacromial pinning. The SUCRA probabilities of CC fixation were in the first rank with 96.8% for CMS, while plate and screw fixation were in the first rank with 67.7 and 93.8% for UCLA score and complications. We recommend using plate and screw and CC fixation as the first- and second-line treatment of unstable distal clavicle fractures. As the quality of studies for this meta-analysis was not high, larger and higher-quality randomized controlled trials are required to confirm these conclusions for informed clinical decision making.
The study indicates that, although orthopaedic physicians had positive attitudes towards providing ADR information to patients, improvement is needed in communicating NSAID risk information.
Background:Adequate graft size and length are crucial factors that correlate with improved outcomes after anterior cruciate ligament reconstruction with a semitendinosus (ST) tendon autograft alone. Anthropometric parameters could be used as predictors of graft measurements but they have shown imprecise correlation in some patients.Purpose:To evaluate the accuracy of ultrasound (US) for the preoperative evaluation of ST graft size and length.Study Design:Cohort study (diagnosis); Level of evidence, 3.Methods:A total of 40 patients were included in this study. Patient sex, age, anthropometric parameters, and preoperative US measurements were recorded. After the ST tendons were harvested, their lengths as well as the diameters of the 4-strand ST grafts were recorded. Correlations between patient US measurements were analyzed. Inadequate ST graft length was defined at <28 cm, and inadequate 4-strand ST graft diameter was defined at <8 mm.Results:The prevalence of patients with an ST graft length <28 cm was 47.5%, and the prevalence of patients with a 4-strand ST graft diameter <8 mm was 42.5%. US measurements had a strong, significant correlation with the ST graft length (P < .001) and a moderate correlation with the 4-strand ST graft diameter (P < .001). Absolute agreement between the preoperative US measurement of ST graft length and the intraoperative ST graft length showed good reliability (ICC2,1 = 0.825). The cross-sectional area (CSA) of the ST tendon at the knee joint level by US showed a weak correlation (r = 0.207) with the 4-strand ST graft diameter (P = .200). A CSA of 16 mm2 measured by US could be used to predict a 4-strand ST graft diameter ≥8 mm, with a sensitivity of 73.9% and specificity of 76.5%.Conclusion:Preoperative US measurements of ST tendons had a strong correlation with intraoperative ST graft length and provided good sensitivity to detect a 4-strand ST graft diameter ≥8 mm. All other anthropometric parameters showed a weak to moderate correlation with ST graft length and size.
