Review
PURPOSE
The All-Inside PCL Reconstruction is a surgical technique which overcomes some of the key challenges faced with traditional PCL Reconstruction, and is becoming more relevant as the rate of PCL reconstruction increases.The purpose of this study is to review the technical practices of the all-inside PCL reconstruction since it was first introduced, with respect to the various key components involved in the surgical technique, to provide more information to the surgeon of the various surgical options available in practice.
MATERIALS AND METHODS
A systematic review was performed by the authors in January 2023 as per Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines to identify all studies outlining the all-inside surgical technique in the past decade. The predetermined eligibility criteria were applied in the screening of the literature in Pubmed, Cochrane and Google Scholar databases.
RESULTS
A total of 14 studies were included in the final review, 9 technical studies, 2 case series, 2 book chapters and 1 review. An allograft was the preferred choice in 9 of the 14 studies. The semitendinosus was preferred when an autograft was chosen. Quadruple folding of the graft was the preferred configuration in 11 studies with the graft diameters from 8 to 12 mm and length ranging from 60 to 150 mm. The femur socket length ranged from 15 to 35 mm and the tibia socket length ranged from 20 to 70 mm. All the studies reported the use of at least 3 portals and up to 6 portals was also reported. 13 studies reported the graft docking first into tibia socket followed by the femoral socket. 7 studies reported the graft entry via the AM portal and 6 studies used a lateral portal. 9 studies used augmentation such as suture anchors (6 studies) and suture tape (3 studies). The 30° and 70° arthroscopic lenses were used alternatingly in 8 studies and fluoroscopy was utilized in 10 studies.
CONCLUSION
The current literature review of all-inside PCL reconstruction consisted mainly technical studies and more clinical outcomes studies are needed to determine its efficacy. It observed a trend to use an allograft, at least 3 portals and docking the graft in the tibia socket first. There is no obvious preference of portal for graft entry.

Review
Evaluating the optimal management strategy for intraoperative iatrogenic injury to the medial collateral ligament during primary total knee arthroplasty: A systematic review.
INTRODUCTION
Intraoperative iatrogenic MCL injuries during primary TKA are rare complications that lack a gold standard management protocol. This review aims to provide insight into various treatment modalities and evidence-based guidance for improved patient outcomes.
METHODS
A comprehensive search across five databases identified relevant randomized control trials and retrospective cohort studies with reported outcomes. A total of 17 studies were included, and variables such as patient demographics, injury type, management, and Knee Society Scores (KSS) were assessed. The quality of included studies was evaluated using the Critical Appraisal Skills Programme tool.
RESULTS
Mean age of included patients ranged from 60.0 to 71.4 years. The mean Body Mass Index ranged from 26.75 to 34.40 kg/m. Among the included knees, 298 were categorized as MCL avulsion, and 167 as midsubstance/transection injuries. Primary repair with sutures or bone staples emerged as the most common management. Intraoperative MCL injury was correlated with reduced preoperative range of motion (ROM) and postoperative KSS clinical, functional, and pain scores compared to control groups. Postoperative ROM was comparable between MCL injury and control groups, ranging from 100.0° to 130.0° and 107.0° to 130.0°, respectively.
CONCLUSION
Current evidence supports primary repair as the preferred management for this complication. Factors such as extent of the tear, type of injury, and the surgeon's experience also help to guide treatment. While treatment modalities like allograft or autograft reconstruction show promise, further research with larger sample sizes is needed to enhance future outcomes.

Review
This systematic review, registered with Prospero, aims to identify an optimal animal model for meniscus repair research, moving from ex vivo experimentation to in vivo studies. Data sources included PubMed, Medline, all Evidence-Based Medicine Reviews, Web of Science, and Embase searched in March 2023. Studies were screened using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Extracted data including animal model, type of experiment, type of tear, surgical techniques, and measured outcomes, were recorded, reviewed, and analyzed by four independent reviewers. The SYstematic Review Centre for Laboratory animal Experimentation (SYRCLE) Rob tool was used for critical appraisal and risk of bias assessment. Out of 11,719 studies, 72 manuscripts were included for data extraction and analysis; 41 ex vivo extra-articular studies, 20 ex vivo intra-articular studies, and only 11 in vivo studies. Six animal models were employed: porcine, bovine, lapine, caprine, canine, and ovine. Longitudinal lesions were the most frequently studied tear pattern and sutures the most common repair technique. Studied outcomes focused mainly on biomechanical assessments and gross observations. This systematic review can guide researchers in their choice of animal model for meniscus repair research; it highlighted the strengths of the porcine, caprine, and bovine models for ex vivo cadaveric studies, while the porcine and caprine models were found to be more suited to in vivo studies due to their similarities with human anatomy. Research teams should familiarize themselves with the advantages and disadvantages of various animal models before initiating protocols to improve standardization in the field.

Meta-Analysis
BACKGROUND
Leaks following bariatric surgery, while rare, are potentially fatal due to risk of peritonitis and sepsis. Anastomotic leaks and gastro-gastric fistulae following Roux-En-Y gastric bypass (RYGB) as well as staple line leaks after sleeve gastrectomy have historically been treated multimodally with surgical drainage, aggressive antibiotic therapy, and more recently, endoscopically. Endoscopic clipping using over-the-scope clips and endoscopic suturing are two of the most common approaches used to achieve full thickness closure.
METHODS
A systematic literature search was performed in PubMed to identify articles on the use of endoscopic clipping or suturing for the treatment of leaks and fistulae following bariatric surgery. Studies focusing on stents, and those that incorporated multiple closure techniques simultaneously, were excluded. Literature review and meta-analysis were performed with the PRISMA guidelines.
RESULTS
Five studies with 61 patients that underwent over-the-scope clip (OTSC) closure were included. The pooled proportion of successful closure across the studies was 81.1% (95% CI 67.3 to 91.7). The successful closure rates were homogeneous (I = 39%, p = 0.15). Three studies with 92 patients that underwent endoscopic suturing were included. The weighted pooled proportion of successful closure across the studies was shown to be 22.4% (95% CI 14.6 to 31.3). The successful closure rates were homogeneous (I = 0%, p = 0.44). Three of the studies, totaling 34 patients, examining OTSC deployment reported data for reintervention rate. The weighted pooled proportion of reintervention across the studies was 35.0% (95% CI 11.7 to 64.7). We noticed statistically significant heterogeneity (I = 68%, p = 0.04). One study, with 20 patients examining endoscopic suturing, reported rate of repeat intervention 60%.
CONCLUSION
Observational reports show that patients managed with OTSC were more likely to experience healing of their defect than those managed with endoscopic suturing. Larger controlled studies comparing different closure devices for bariatric leaks should be carried out to better understand the ideal endoscopic approach to these complications.

Effects of Perineal Warm Compresses during the Second Stage of Labor on Reducing Perineal Trauma and Relieving Postpartum Perineal Pain in Primiparous Women: A Systematic Review and Meta-Analyses.
Non-pharmaceutical midwifery techniques, including perineal warm compresses, to improve maternal outcomes remain controversial. The aims of this study are to assess the effects of perineal warm compresses on reducing perineal trauma and postpartum perineal pain relief. This systematic review included randomized controlled trials (RCTs). We searched seven bibliographic databases, three RCT register websites, and two dissertation databases for publications from inception to 15 March 2023. Chinese and English publications were included. Two independent reviewers conducted the risk of bias assessment, data extraction, and the evaluation of the certainty of the evidence utilizing the Cochrane risk of bias 2.0 assessment criteria, the Review Manager 5.4, and the online GRADEpro tool, respectively. Seven RCTs involving 1362 primiparous women were included. The combined results demonstrated a statistically significant reduction in the second-, third- and/or fourth- degree perineal lacerations, the incidence of episiotomy, and the relief of the short-term perineal pain postpartum (within two days). There was a potential favorable effect on improving the integrity of the perineum. However, the results did not show a statistically significant supportive effect on reducing first-degree perineal lacerations and the rate of perineal lacerations requiring sutures. In summary, perineal warm compresses effectively reduced the second-, third-/or fourth-degree perineal trauma and decreased the short-term perineal pain after birth.

Arthroscopic Surgery Combined With Platelet-Rich Plasma Does Not Significantly Improve Pain, Function, Complications, and Retear Rate Compared With Arthroscopic Surgery Alone for Full-Thickness Rotator Cuff Tears: A Systematic Review and Meta-analysis.
PURPOSE
To evaluate the effectiveness and safety of arthroscopic surgery combined with platelet-rich plasma (PRP) compared with arthroscopic surgery alone in the treatment of patients with full-thickness rotator cuff tears.
METHODS
The Cochrane Library, PubMed, Embase, Scopus, EBSCO, Web of Science, China National Knowledge Infrastructure, and Wanfang Database were systematically searched from inception to November 2023. Subject words combined with free words were used to collect randomized controlled trials focusing on arthroscopic surgery combined with PRP in the treatment of full-thickness rotator cuff tears. The assessment of evidence quality employed the Cochrane Collaboration risk of bias tool, and data analysis was performed using RevMan 5.3 software.
RESULTS
A total of 9 studies with 537 patients were included. The meta-analysis revealed that compared with the arthroscopic surgery alone group, the summary result of University of California Los Angeles score scores in the arthroscopic combined with PRP group was (mean difference [MD] = 1.08, 95% confidence interval [CI] 0.19∼1.97, P = .02), subgroup analysis of surgical suture method visual analog scale (VAS) single-row (MD = -1.00, 95% CI -1.50 to -0.50, P < .0001), VAS double-row (MD = -0.10, 95% CI -0.17 to -0.02, P = .02), and Constant-Murley score single-row (MD = 3.49, 95% CI 0.32∼6.66, P = .03), the difference was statistically significant, and the differences in VAS, Constant-Murley score, and Quick Disabilities of the Arm, Shoulder and Hand, complications, and retear rate were not statistically significant.
CONCLUSIONS
Patients undergoing arthroscopic repair combined with PRP treatment showed no difference in pain, function, complications, and retear rate compared with those treated with arthroscopic surgery alone.

Review
Persistent postsurgical pain (PPSP) is one of the most bothersome and disabling long-term complications after inguinal hernia repair surgery. Understanding perioperative risk factors that contribute to PPSP can help identify high-risk patients and develop risk-mitigation approaches. The objective of this study was to systematically review and meta-analyze risk factors that contribute to PPSP after inguinal hernia repair. The literature search resulted in 303 papers included in this review, 140 of which were used for meta-analyses. Our results suggest that younger age, female sex, preoperative pain, recurrent hernia, postoperative complications, and postoperative pain are associated with a higher risk of PPSP. Laparoscopic techniques reduce the PPSP occurrence compared to anterior techniques such as Lichtenstein repair, and tissue-suture techniques such as Shouldice repair. The use of fibrin glue for mesh fixation was consistently associated with lower PPSP rates compared to tacks, staples, and sutures. Considerable variability was observed with PPSP assessment and reporting methodology in terms of study design, follow-up timing, clarity of pain definition, as well as pain intensity or interference threshold. High or moderate risk of bias in at least one domain was noted in >75% of studies. These may limit the generalizability of our results. Future studies should assess and report comprehensive preoperative and perioperative risk factors for PPSP adjusted for confounding factors, and develop risk-prediction models to drive stratified PPSP-mitigation trials and personalized clinical decision-making. PERSPECTIVE: This systematic review and meta-analysis summarizes the current evidence on risk factors for persistent pain after inguinal hernia repair. The findings can help identify patients at risk and test personalized risk-mitigation approaches to prevent pain.

INTRODUCTION
Thorough validation of novel microsurgical techniques is deemed essential before their integration into clinical practice. To achieve proper validation, the design of randomized controlled trials (RCTs) should be undertaken, accompanied by the execution of comprehensive statistical analyses, including confounder adjustment and power analysis. This systematic review aims to provide an encompassing overview of the validation methodologies employed in microsurgical studies, with a specific focus on innovative vessel anastomosis techniques.
METHODS
A literature search was conducted in PubMed for articles describing the validation of novel microsurgical vessel anastomosis techniques in animal or human subjects.
RESULTS
The literature search yielded 6,658 articles. A total of 6,564 articles were excluded based on title and abstract. Ninety-four articles were assessed for full-text eligibility. Forty-eight articles were included in this systematic review. Out of 30 comparative studies, 9 studies validated novel modified interrupted suture techniques, 6 studies modified continuous techniques, 6 studies modified sleeve anastomosis techniques, 1 study a modified vesselotomy technique, 7 studies sutureless techniques, and 1 study a modified lymphaticovenular anastomosis technique. Twenty-eight studies contained animals ( = 1,998). Fifteen animal studies were RCTs. Two studies contained human/cadaveric subjects ( = 29). Statistical power analysis and confounder adjustment were performed in one animal study. Out of 18 noncomparative studies, 5 studies validated novel modified interrupted suture techniques, 1 study a modified continuous technique, 2 studies modified sleeve anastomosis techniques, 4 studies modified vesselotomy techniques, 4 studies sutureless techniques, and 2 studies modified lymphaticovenular anastomosis techniques. Ten studies contained animal subjects ( = 320), with two RCTs. Eight studies contained human subjects ( = 173). Statistical power analysis and confounder adjustment were performed in none of the animal or human studies.
CONCLUSION
The current methods of microsurgical technique validation should be reconsidered due to poor study design. Statistical analysis including confounder adjustment and power analysis should be performed as a standard method of novel technique validation.

BACKGROUND
Seroma formation is the most common complication of abdominoplasties. Many preventive interventions have been proposed, but none have been recognized as a definitive solution, partly due to varying levels of evidence (LOE) in the literature.
OBJECTIVES
We aimed to analyze seroma prevention methods supported by high-level evidence.
METHODS
The PubMed database was queried through August 2023. Primary articles of interest included randomized controlled trials (RCTs), prospective comparative studies, and meta-analyses of these studies. The LOE for each article was determined according to the American Society of Plastic Surgeons Rating Scale. The "seroma occurrence ratio," or ratio of seroma events in the interventional group to respective control group, was calculated to compare incidence rates between techniques.
RESULTS
Twenty articles and 9 categories of techniques were analyzed. Study designs included 10 RCTs, 2 prospective cohort studies, 7 prospective comparative studies, and 1 retrospective randomized study. The use of progressive-tension and quilting sutures had the most data supporting a statistically significant reduction in seroma (occurrence ratio 0.306, < .001). Tissue adhesives and preservation of Scarpa's fascia were also well reinforced (0.375, < .01 and 0.229, < .011, respectively), while increasing the number of drains was not ( = .7576). Meta-analysis demonstrated that compared with 2 drains alone, alternative techniques were more effective at reducing seroma occurrence (pooled risk ratio 0.33, 95% CI, 0.11-0.99).
CONCLUSIONS
This review highlights multiple seroma prevention techniques for abdominoplasty investigated in recent high-quality literature. We suggest future randomized comparative studies of the various seroma prevention methods to fully ascertain their efficacy following abdominoplasty.

Review
OBJECTIVES
The medial collateral ligament (MCL) injury is one of the possible complications of primary total knee arthroplasty (TKA), which can lead to coronal-plane instability that requires surgical revision. Injured MCL can result in joint instability and polyethylene wear. Different strategies have been proposed for MCL reconstruction based on the location of the injury. However, there is a lack of clarity regarding the optimal method for handling an iatrogenic MCL injury throughout a TKA.
METHODS
A PRISMA flow diagram was used to guide the systematic literature review. An extensive search was conducted in PubMed, Embase, Scopus, Web of Science, and Google Scholar. Newcastle Ottawa scale checklist was used to assess the methodological quality of the articles.
RESULTS
A total of 19 qualitative studies, including non-cadaveric patients with MCL injury during TKA, were identified after analyzing the full text of the articles. All included studies were either retrospective, observational cohort or case series. A total of 486 patients were studied to gather information on the methods used to repair the MCL and their results. Most injuries arose in the tibial attachment, which surgeons mostly realized during the final stages of surgery. Used techniques can be categorized into three main groups: Primary repair, Repair with augmentation, and changing prosthesis characteristics.
CONCLUSION
This systematic review demonstrated that the most popular management of iatrogenic MCL injury was using suture anchors, staples, screws and washers, and more constrained prostheses. The proper method should be decided considering the site of the MCL injury.
