Meta-Analysis
BACKGROUND
Neuromuscular deficits are common following knee injuries and may contribute to early-onset post-traumatic osteoarthritis, likely mediated through quadriceps dysfunction.
OBJECTIVE
To identify how peri-articular neuromuscular function changes over time after knee injury and surgery.
DESIGN
Systematic review with meta-analyses.
DATA SOURCES
PubMed, Web of Science, Embase, Scopus, CENTRAL (Trials).
ELIGIBILITY CRITERIA FOR SELECTING STUDIES
Moderate and high-quality studies comparing neuromuscular function of muscles crossing the knee joint between a knee-injured population (ligamentous, meniscal, osteochondral lesions) and healthy controls. Outcomes included normalized isokinetic strength, muscle size, voluntary activation, cortical and spinal-reflex excitability, and other torque related outcomes.
RESULTS
A total of 46 studies of anterior cruciate ligament (ACL) and five of meniscal injury were included. For ACL injury, strength and voluntary activation deficits were evident (moderate to strong evidence). Cortical excitability was not affected at < 6 months (moderate evidence) but decreased at 24+ months (moderate evidence). Spinal-reflex excitability did not change at < 6 months (moderate evidence) but increased at 24+ months (strong evidence). We also found deficits in torque variability, rate of torque development, and electromechanical delay (very limited to moderate evidence). For meniscus injury, strength deficits were evident only in the short-term. No studies reported gastrocnemius, soleus or popliteus muscle outcomes for either injury. No studies were found for other ligamentous or chondral injuries.
CONCLUSIONS
Neuromuscular deficits persist for years post-injury/surgery, though the majority of evidence is from ACL injured populations. Muscle strength deficits are accompanied by neural alterations and changes in control and timing of muscle force, but more studies are needed to fill the evidence gaps we have identified. Better characterisation and therapeutic strategies addressing these deficits could improve rehabilitation outcomes, and potentially prevent PTOA.

BACKGROUND
Anterior cruciate ligament (ACL) tears are debilitating injuries frequently suffered by athletes. ACL reconstruction is indicated to restore knee stability and allow patients to return to prior levels of athletic performance. While existing literature suggests that patient-reported outcomes are similar between bone-patellar tendon-bone (BTB) and hamstring tendon (HT) autografts, there is less information comparing return-to-sport (RTS) rates between the 2 graft types.
PURPOSE
To compare RTS rates among athletes undergoing primary ACL reconstruction using a BTB versus HT autograft.
STUDY DESIGN
Systematic review; Level of evidence, 4.
METHODS
The MEDLINE, Embase, and Cochrane Library databases were searched, and studies that reported on RTS after primary ACL reconstruction using a BTB or HT autograft were included. Studies that utilized ACL repair techniques, quadriceps tendon autografts, graft augmentation, double-bundle autografts, allografts, or revision ACL reconstruction were excluded. RTS information was extracted and analyzed from all included studies.
RESULTS
Included in the review were 20 articles investigating a total of 2348 athletes. The overall RTS rate in our cohort was 73.2%, with 48.9% returning to preinjury levels of performance and a rerupture rate of 2.4%. The overall RTS rate in patients after primary ACL reconstruction with a BTB autograft was 81.0%, with 50.0% of athletes returning to preinjury levels of performance and a rerupture rate of 2.2%. Patients after primary ACL reconstruction with an HT autograft had an overall RTS rate of 70.6%, with 48.5% of athletes returning to preinjury levels of performance and a rerupture rate of 2.5%.
CONCLUSION
ACL reconstruction using BTB autografts demonstrated higher overall RTS rates when compared with HT autografts. However, BTB and HT autografts had similar rates of return to preinjury levels of performance and rerupture rates. Less than half of the athletes were able to return to preinjury sport levels after ACL reconstruction with either an HT or BTB autograft.

CONTEXT
Anterior cruciate ligament (ACL) reconstruction (ACLR) is frequently performed in patients younger than 20 years whose goal is to return to sport (RTS). Varying reinjury rates have been reported, and the factors responsible are unclear. Studies differ with regard to age, graft type, surgical techniques, postoperative rehabilitation, RTS guidelines, and methods used to determine ACL failures.
OBJECTIVE
To determine RTS rates; the effect of participation in high-risk sports, sex, and graft type on ACL reinjury rates; and whether objective test criteria before RTS correlate with lower reinjury rates.
DATA SOURCES
A systematic review of the literature from inception to May 31, 2019, was conducted using the PubMed and Cochrane databases.
STUDY SELECTION
Studies on transphyseal ACLR in athletes <20 years old with a minimum mean follow-up of 2 years that reported reinjury rates, the number that RTS, and detailed the type of sport were included.
STUDY DESIGN
Systematic review.
LEVEL OF EVIDENCE
Level 4.
RESULTS
A total of 1239 patients in 8 studies were included; 87% returned to sport and 80% resumed high-risk activities. Of the patients, 18% reinjured the ACL graft and/or the contralateral ACL. Nine percent of patellar tendon autografts and 15% of hamstring autografts failed (odds ratio [OR], 0.52; = 0.002). Of reinjuries, 90% occurred during high-risk sports. Male patients had a significantly higher rate of ACL graft failure than female patients (OR, 1.64; = 0.01). There was no sex-based effect on contralateral ACL injuries. Only 1 study cited objective criteria for RTS.
CONCLUSION
A high percentage of athletes returned to sport, but 1 in 5 suffered reinjuries to either knee. Male patients were more likely to reinjure the ACL graft. Objective criteria for RTS were rarely mentioned or not detailed. The need for testing of knee stability, strength, neuromuscular control, agility, and psychological measures before RTS remains paramount in young athletes.

Review
OBJECTIVE
This study proposes to systematically review the literature and compare data on (1) function, (2) pain, (3) return to sport, and (4) complications after anterior cruciate ligament (ACL) reconstruction with quadriceps tendon autograft (QT) and hamstring tendon autograft (HT).
METHODS
In June 2021, a systematic review of the EMBASE, MEDLINE/PubMed, Cochrane Central Register of Controlled Trials, and LILACS databases was performed, based on PRISMA guidelines. The search strategy included the keywords: "Previous Cruciate Ligament Reconstruction," "ACL reconstruction," "quadriceps tendon autograft," "quadriceps graft," "Hamstring-Tendon Autografts." Meta-analyses were performed using Review Manager software (RevMan Web).
RESULTS
There were no significant differences between the two groups regarding function according to Lysholm score (MD 3.01; CI-0.30, 6.33, p = 0.08), the presence of pain (RR 0.89; CI-0.57, 1.39, p = 0.60), and re-rupture (RR 0.60; IC-0.19, 1.88, p = 0.38).
CONCLUSION
QT and HT autografts show comparatively good results in ACL reconstruction without significant differences regarding function, pain, and rupture after surgical intervention.

Given the limitations in the available literature, the precise indications, techniques, and outcomes of anterior skull base free flap reconstruction remain uncertain. The objective of this study was to perform a systematic review of published literature and evaluate indications, methods, and complications for anterior skull base free flap reconstruction. A systematic review of the literature was performed using a set of search criteria to identify patients who underwent free flap reconstruction of the anterior skull base. Articles were reviewed for inclusion based on relevance, with the primary outcome being surgical complications. After a comprehensive search, 406 articles were obtained and 16 articles were ultimately found to be relevant to this review-79 patients undergoing free flap reconstruction were identified. Overall complication rates were 17.7% (95% confidence interval [CI]: 16.6-33.1%) for major complications and 19.0% (95% CI: 17.8-35.5%) for minor complications. Microvascular reconstruction of the anterior skull base is feasible with high reliability reported in the literature.

Review
BACKGROUND
Reports of glenohumeral translation in shoulders with traumatic anterior instability have been presented. The aim of this systematic review was to investigate anterior-posterior translation in shoulders with traumatic anterior instability.
METHODS
This systematic review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies including patients aged ≥15 years with previous traumatic anterior shoulder dislocation or subluxation were included. The outcome was anterior-posterior glenohumeral translation. A search of PubMed, Embase, and Cochrane library was performed on July 17, 2022. Two reviewers individually screened titles and abstracts, reviewed full text, extracted data, and performed quality assessment.
RESULTS
Twenty studies (582 unstable shoulders in total) of varying quality were included. There was a lack of standardization and unity across studies. Radiography, ultrasound, computed tomography, magnetic resonance imaging, motion tracking, instrumentation, and manual testing were used to assess the glenohumeral translation. The glenohumeral translation in unstable shoulders ranged from 0.0 ± 0.8 mm to 11.6 ± 3.7 mm, as measured during various motion tasks, arm positions, and application of external force. The glenohumeral translation was larger or more anteriorly directed in unstable shoulders than in stable when contralateral healthy shoulders or a healthy control group were included in the studies. Several studies found that the humeral head was more anteriorly located on the glenoid in the unstable shoulders.
CONCLUSION
This systematic review provides an overview of the current literature on glenohumeral translation in traumatic anterior shoulder instability. It was not able to identify a threshold for abnormal translation in unstable shoulders, due to the heterogeneity of data. The review supports that not only the range of translation but also the direction hereof as well as the location of the humeral head on the glenoid seem to be part of the pathophysiology. Technical development and increased attention to research methodology in recent years may provide more knowledge and clarity on this topic in the future.

Review
BACKGROUND
Urethral surgery outcomes are often evaluated by assessing urinary flow and urethral patency. However, sexual consequences may appear after urethroplasty, impairing quality of life and patient's perception of success.The aim of this study is to assess the relationship between anterior urethral reconstruction and postoperative sexual dysfunction, including the proposed factors predicting sexual outcomes.
METHODS
We searched in PubMed database using the terms: "anterior urethroplasty", bulbar urethroplasty" or "penile urethroplasty", and "sexual dysfunction", "erectile function" or "ejaculation". Articles were independently evaluated for inclusion based on predetermined criteria. Systematic data extraction was followed by a comprehensive summary of evidence.
RESULTS
Thirty-eight studies were included for final analysis. No randomised trial on the topic was found. Urethral surgery might affect different aspects of sexual function: erectile function, ejaculatory function, penile shape and length, and genital sensitivity, leading to severe sexual dysfunction. Patient perception of sexual impairment was related to post-operative satisfaction.
CONCLUSIONS
Sexual dysfunction after anterior urethral reconstruction is an important issue that must be appropriately discussed during preoperative patient counselling. Reported outcomes after anterior urethroplasty should include sexual consequences and relevance, evaluated using validated tools.

Anterior fontanel is an integral element of an infant craniofacial system. There are six fontanels in the newborn skull, namely anterior, posterior, two mastoid, and two sphenoid fontanels. The anterior fontanel is the largest, prominent, and most important for clinical evaluation. Sex, race, genetics, gestational age, and region are the principal factors that influence anterior fontanel size. There exist inconclusive findings on the size of anterior fontanel in newborns. Therefore, this systematic review and meta-analysis aimed to determine the pooled mean size of anterior fontanel among term newborns and to identify the pooled mean difference of anterior fontanel size between males and females. PubMed/Medline, Google Scholar, Science Direct, JBI Library, embase, and Cochrane Library databases were systematically searched. All essential data were extracted using a standardized data extraction format. The heterogeneity across studies was assessed using the Cochrane Q test statistic, I test statistic, and -values. A fixed-effect model and random effect model were used to estimate the pooled mean size of anterior fontanel and the pooled mean difference between male newborns and female newborns, respectively. To deal with heterogeneity, sub-group analysis, meta-regression analysis, and sensitivity analysis were considered. JBI quality appraisal checklist was used to evaluate the quality of studies. In this meta-analysis, 8, 661 newborns were involved in twenty-six studies. Among studies, 13 conducted in Asia, 7 in Africa, 5 in America, and 1 in Europe. The pooled mean size of anterior fontanel was 2.58 cm (95% CI: 2.31, 2.85 cm). The pooled mean size of anterior fontanel for Asia, Africa, America, and Europe region was 2.49, 3.15, 2.35, and 2.01 cm, respectively. A statistically significant mean difference was detected between male and female newborns (D + L pooled MD = 0.15 cm, 95% CI: 0.02, 0.29 cm). The pooled estimate of this review does provide the mean value of the anterior fontanel size in the newborns. There was a statistically significant mean fontanel size difference between male and female newborns. Therefore, male newborns had a significantly larger mean size than female newborns.

Review
PURPOSE
To summarize the quantitative and qualitative anatomy of the acromioclavicular (AC) and coracoclavicular (CC) ligaments of the AC joint.
METHODS
A systematic review of the literature evaluating the quantitative and qualitative anatomy of the CC and AC ligaments of the AC joint was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines.
RESULTS
The conoid ligament (CL) arises from the posterior coracoid precipice and courses with a tapered inferior apex to insert on the conoid tubercle of the posteroinferior clavicle. The trapezoid ligament originates from the anterior-superior coracoid with medially extending fibers anterior to the conoid's C-shaped footprint and runs with the CL to insert along the trapezoid line on the inferior aspect of the anterior clavicle, anterolateral to the conoid tubercle. The AC capsule's superoposterior bundle and the CL are robust stabilizing ligaments characterized by prominent attachment sites to the posteroinferior clavicle.
CONCLUSIONS
Clear and consistent quantitative and qualitative descriptions of the CC ligaments (CL and trapezoid ligament) have been well defined; however, quantitative data on the capsuloligamentous anatomy of AC ligaments (superoposterior and anteroinferior) ligaments) remain limited.
CLINICAL RELEVANCE
There are high complication and failure rates after AC joint stabilization. To improve patient outcomes, the anatomy of the CC and AC joints needs to be better understood.

STUDY DESIGN
Systematic review and meta-analysis.
OBJECTIVE
Anterior cervical diskectomy and fusion (ACDF) is an effective surgical option for patients with cervical radiculopathy, myelopathy, or deformity. Although ACDF is generally safe, dysphagia is a common complication. Despite its high incidence, prolonged postoperative dysphagia is poorly understood; its etiology remains relatively unknown, and its risk factors are widely debated.
METHODS
We searched MEDLINE, Scopus, Web of Science, and Embase for studies reporting complications for cervical diskectomy with plating. We recorded dysphagia events from all included studies and calculated effect summary values, 95% confidence intervals (CIs), Q values, and values.
RESULTS
Of the 7,780 retrieved articles, 14 met inclusion criteria. The overall dysphagia rate was 8.5% (95% CI 5.7 to 11.3%). The rate of moderate or severe dysphagia was 4.4% (0.4 to 8.4%). Follow-up times of <12, 12 to 24, and >24 months reported rates of 19.9% (6.0 to 33.7%), 7.0% (5.2 to 8.7%), and 7.6% (1.4 to 13.8%), respectively. Studies utilizing the Bazaz Dysphagia Score resulted in an increase in dysphagia diagnosis relative to studies with no outlined criteria (19.8%, 5.9 to 33.7% and 6.9%, 3.7 to 10.0%, respectively), indicating that the criteria used for dysphagia identification are critical. There was no difference in dysphagia rate with the use of autograft versus allograft.
CONCLUSIONS
This review represents a comprehensive estimation of the actual incidence of dysphagia across a heterogeneous group of surgeons, patients, and criteria. The classification scheme for dysphagia varied significantly within the literature. To ensure its diagnosis and identification, we recommend the use of a standardized, well-outlined method for dysphagia diagnosis.
