Meta-Analysis Review
BACKGROUND
A large number of studies have found that the musculoskeletal injury of modern and contemporary dancers has a high incidence. Previous publications have indicated that there are many potential factors that are related to dancing injury; however, they have not been proven, and even some data are conflicting in different research.
RESULTS
The search yielded 18 prospective studies reporting on professional and pre-professional modern or contemporary dancers from companies and schools. The prevalence of modern and contemporary dancers was 0.82 (: 0.74~0.90). The injury proportion of trauma, overuse, ankle and foot, lower extremity, joint and ligaments, muscle and tendons, and time-loss were 0.40, 0.26, 0.49, 0.34, 0.33, and 0.29 in the total number of injuries. There was no evidence of a significant difference in sex, age, and education program. The factors of BMI and injury history achieved statistical significance, and the -values were less than 0.01.
CONCLUSION
Based on the results of this article, BMI and injury history may be risk factors for injury in contemporary and modern dancers. Modern and contemporary dancers have a high prevalence of musculoskeletal injuries. Lower extremity injuries are the most common in the whole body, with injuries to the foot and ankle being more frequent. The mechanism of injury is mostly overuse injury, and the injured tissues are mostly muscle tendons and joint ligaments.

Meta-Analysis
Immediate mobilization after repair of Achilles tendon rupture may increase the incidence of re-rupture: a systematic review and meta-analysis of randomized controlled trials.
BACKGROUND
Achilles tendon rupture (ATR) is a significant injury that can require surgery and can have the risk of re-rupture even after successful treatment. Consequently, to minimize this risk, it is important to have a thorough understanding of the rehabilitation protocol and the impact of different rehabilitation approaches on preventing re-rupture.
MATERIALS AND METHODS
Two independent team members searched several databases (PubMed, EMBASE, Web of Science, Cochrane Library, and CINAHL) to identify randomized controlled trials (RCTs) on operative treatment of ATR. We included articles that covered open or minimally invasive surgery for ATR, with a detailed rehabilitation protocol and reports of re-rupture. The study protocol has been registered at PROSPERO and has been reported in the line with PRISMA Guidelines, Supplemental Digital Content 1, http://links.lww.com/JS9/C85 , Supplemental Digital Content 2, http://links.lww.com/JS9/C86 and assessed using AMSTAR Tool, Supplemental Digital Content 3, http://links.lww.com/JS9/C87 .
RESULTS
A total of 43 RCTs were eligible for the meta-analysis, encompassing a combined cohort of 2553 patients. Overall, the postoperative incidence of ATR patients developing re-rupture was 3.15% (95% CI: 2.26-4.17; I2 =44.48%). Early immobilization group patients who had ATR had a 4.07% (95% CI: 1.76-7.27; I2 =51.20%) postoperative incidence of re-rupture; Early immobilization + active range of motion (AROM) group had an incidence of 5.95% (95% CI: 2.91-9.99; I2 =0.00%); Early immobilization + weight-bearing group had an incidence of 3.49% (95% CI: 1.96-5.43; I2 =20.06%); Early weight-bearing + AROM group had an incidence of 3.61% (95% CI: 1.00-7.73; I2 =64.60%); Accelerated rehabilitation (immobilization) group had an incidence of 2.18% (95% CI: 1.11-3.59; I2 =21.56%); Accelerated rehabilitation (non-immobilization) group had a rate of 1.36% (95% CI: 0.12-3.90; I2 =0.00%). Additionally, patients in the immediate AROM group had a postoperative re-rupture incidence of 3.92% (95% CI: 1.76-6.89; I2 =33.24%); Non-immediate AROM group had an incidence of 2.45% (95% CI: 1.25-4.03; I2 =22.09%).
CONCLUSIONS
This meta-analysis suggests the use of accelerated rehabilitation intervention in early postoperative rehabilitation of the Achilles tendon. However, for early ankle joint mobilization, it is recommended to apply after one to two weeks of immobilization.

Review
Posterior pilon variant ankle fractures (PPVF) are a unique subtype of posterior malleolar fractures which have been a source of controversy and confusion in recent years. There has not been a thorough literature review previously written on the topic. Database searches of PubMed and Embase were conducted from inception until June 2023. The key words included "pilon variant," "posterior pilon variant," and "posterior pilon" fractures. Outcomes were evaluated by union time, rates of delayed union, nonunion, malunion, and complication. A total of 15 articles relevant to surgical repair of pilon variant fractures were included in the literature review. The unique mechanism of injury has been reported to involve both rotational and axial forces, leading to involvement of the posterior and medial aspects of the distal tibia. Pilon variant fractures can be suspected by several characteristics on radiographs and have a high confirmation rate via CT images. Multiple systems have been proposed to classify this fracture pattern, but there is no consensus on the ideal classification system. Surgically, direct fixation has shown better short-term clinical outcomes versus indirect fixation or no fixation. PPVF have a distinct fracture pattern involving the posterior and medial columns of the distal tibial plafond, and results from a mechanism intermediate to rotational and axial forces. These fractures are more severe than tri-malleolar fractures due to increased rates of articular impaction and incongruity. Future classification systems should focus on joint surface area and the tibial pilon column involved to avoid confusion with less severe posterior malleolar fractures.

Meta-Analysis
PURPOSE
The purpose of this systematic review and meta-analysis was to evaluate the prevalence and clinical significance of heterotopic ossification (HO) following total ankle replacement (TAR).
METHODS
During August 2023, the PubMed, Embase and Cochrane library databases were systematically reviewed to identify clinical studies reporting HO following TAR. Data regarding surgical characteristics, pathological characteristics, subjective clinical outcomes, ankle range of motion, radiographic outcomes, reoperation rates were extracted and analysed.
RESULTS
Twenty-seven studies with 2639 patients (2695 ankles) at a weighed mean follow-up time of 52.8 ± 26.9 months were included. The pooled prevalence rate was 44.6% (0.25; 0.66). The implant with the highest rate of HO was the INBONE I (100%) and BOX (100%) implants. The most common modified Brooker staging was grade 1 (132 patients, 27.0%). Random effects models of standardized mean differences found no difference in American orthopedic foot and ankle society (AOFAS) scores, visual analog scale scores (VAS) and ankle range of motion (ROM) between patients with HO and patients without HO. Random effects models of correlation coefficients found no correlation between AOFAS, VAS and ROM and the presence of HO. The surgical intervention rate for symptomatic HO was 4.2%.
CONCLUSION
This systematic review and meta-analysis found that HO is a common finding following TAR that is not associated with inferior clinical outcomes. Surgical intervention was required only for moderate-to-severe, symptomatic HO following TAR. This study is limited by the marked heterogeneity and low level and quality of evidence of the included studies. Further higher quality studies are warranted to determine the precise prevalence and impact of HO on outcomes following TAR.

Review
UNLABELLED
Damage to the articular cartilage resulting in an acute tear can lead to functional changes within the joint and increase the risk of osteoarthritis developing. There is limited understanding of the association between occupational risk factors and sustaining an acute articular cartilage tear in the military and other physically demanding occupations. Therefore, the aim of this systematic review was to identify and evaluate original research reporting on occupational risk factors associated with sustaining acute articular cartilage tears.
METHODS
A systematic review following the Preferred Reporting Items for Systematic review and Meta-Analysis-Protocols was conducted and registered with the Open Science Framework. Key academic databases were searched using terms from the following concepts: risk or cause, paid occupations, and acute articular cartilage tears.
RESULTS
Of an initial 941 studies, 2 studies met the eligibility criteria, both reporting data from military contexts; only one evaluated acute articular cartilage tears in both males and females. One paper focused on articular cartilage injury within the knee and the other within the ankle joint with incidence rates being 0.2 and 0.3 per 1000 person-years, respectively. People in more physically active occupations and individuals with an above-normal body mass index were reported as being at higher risk of sustaining an acute articular cartilage tear.
CONCLUSION
Physically demanding occupations, such as the military, may increase the risk for acute tears of the articular cartilage. However, the findings of this review indicate there is a paucity of research to underpin understanding of the injury mechanisms and occupational risk factors for acute articular cartilage tears.

BACKGROUND
The Lisfranc joint is an intricate podiatric medical structure that when injured can prove difficult to treat. No consensus has been established on optimal surgical management for this injury. It is widely debated whether open reduction and internal fixation or primary arthrodesis provides better outcomes for patients. Although literature has been published on this subject, no generalized guidelines have been created. The goal of this study was to analyze high-level meta-analyses to draw conclusions about surgical interventions for Lisfranc joint injuries.
METHODS
A literature review was conducted to analyze outcomes of meta-analyses from January 1, 2016, to August 31, 2021. Only high-level evidence that reported at least one of the following outcomes was included: American Orthopaedic Foot and Ankle Society scale score, visual analog scale score, total complication rate, hardware removal rate, revision surgery rate, and secondary procedure rate.
RESULTS
Six articles met the inclusion and exclusion criteria and were then analyzed. For all of the outcome measures, primary arthrodesis was equal or superior to open reduction and internal fixation.
CONCLUSIONS
We recommend primary arthrodesis over open reduction and internal fixation for adult Lisfranc injuries.

Journal of Orthopaedics Jun 2024This systematic review and meta-analysis investigated the treatment for Achilles tendon rupture (ATR) associated with the lowest risk of rerupture in older patients. (Review)
Review
BACKGROUND
This systematic review and meta-analysis investigated the treatment for Achilles tendon rupture (ATR) associated with the lowest risk of rerupture in older patients.
METHODS
Five databases were searched through September 2022 for studies published in the past 10 years analyzing operative and nonoperative ATR treatment. Studies were categorized as "nonelderly" if they reported only on patients aged 18-60 years. Studies that included at least 1 patient older than age 70 were categorized as "elderly inclusive." Of 212 studies identified, 28 were eligible for inclusion. Of 2965 patients, 1165 were treated operatively: 429 (37%) from elderly-inclusive studies and 736 (63%) from nonelderly studies. Of the 1800 nonoperative patients 553 (31%) were from nonelderly studies and 1247 (69%) were from elderly-inclusive studies.
RESULTS
For nonoperative treatment, the rate of rerupture was higher in nonelderly studies (83/1000 cases, 95% CI = 58, 113) than in elderly-inclusive studies (38/1000 cases, 95% CI = 22, 58; <.001). For operative treatment no difference was found in the rate of rerupture between nonelderly studies (7/1000 cases, 95% CI = 0, 21) and elderly-inclusive studies (12/1000 cases, 95% CI = 0, 35; <.78). Overall, operative treatment was associated with a rerupture rate of 1.5% (95% CI: 1.0%, 2.8%) (<.001), which was lower than the 5% rate reported by other studies for nonoperative management (<.001).
CONCLUSION
Older patients may benefit more than younger patients from nonoperative treatment of ATR. More studies are needed to determine the age at which rerupture rates decrease among nonoperatively treated patients.

Meta-Analysis Review
BACKGROUND
Main objective of this research is to know if there is a different survival rate between fixed bearing (FB) and mobile bearing (MB) total ankle replacement (TAR). We hypothesized that there are no differences between the survival rates of both implants.
METHODS
A systematic search was performed in PubMed, Cochrane, EMBASE and ClinicalTrials.gov databases to identify published studies from August 2018 to September 2022 including results for FB and MB TAR survivorship. Inclusion criteria included 1) primary TAR in one or both feet in which implant could be identified, 2) a minimum of 20 procedures reported, 3) reported implant survivorship or calculable and 4) a minimum of 12 months follow-up for level 1-3 studies or 60 months for level 4 studies.
RESULTS
3902 ankles in 28 studies were included. 719 were FB and 3104 MB with an overall survivorship of 94% (95% CI [0.89; 0.97]) and 89% (95% CI [0.86; 0.92]) respectively. After subgroup analysis, we did not find differences among both groups (p = 0.429). Meta-regression analysis showed that longer follow-up was associated with lower survival rates in MB group (p = 0.000) while no other relationships were found with other factors (age, level of evidence or conflict of interests).
CONCLUSIONS
No differences in survival rates between both groups were found. Age and other studied confounders were not found to be related with implant survivorship. However, longer follow-up was found to be related with lower survival rates. Studies with longer follow-up and higher level of evidence are needed to confirm results.

Meta-Analysis Review
BACKGROUND
Foot orthoses (FOs) are often prescribed by clinicians to treat foot and ankle conditions, prevent running injuries, and enhance performance. However, the lack of higher-order synthesis of clinical trials makes it challenging for clinicians to adopt an evidence-based approach to FOs' prescriptions.
RESEARCH QUESTION
Do FOs with different modifications alter lower extremity running kinematics and kinetics?
METHODS
A systematic search of seven databases was conducted from inception to February 2023. The analysis was restricted to healthy adults without foot musculoskeletal impairments and studies that compared the FOs effects with the controls. The methodological quality of the 35 studies that met the eligibility criteria was evaluated using the modified Downs and Black checklist. The random effects model estimated the standardized mean difference (SMD) with 95% confidence intervals and effect sizes. Sub-group analyses based on FOs type were performed to assess the potential effects of the intervention.
RESULTS
Our findings indicated that both custom and off-the-shelf arch-support FOs reduced peak plantar pressure at the medial heel (SMD=-0.35, and SMD=-1.03), lateral heel (SMD=-0.50, and SMD=-0.53), and medial forefoot (SMD=-0.20, and SMD=-0.27), but increased plantar pressure at the mid-foot (SMD=0.30, and SMD=0.56). Compared with the controls, significant increases (SMD=0.36) in perceived comfort were found with custom FOs. A reduction (SMD=-0.58) in initial ankle inversion was found when a raised heel cup was integrated with arch-support FOs. A medial post integrated with arch support exhibited a reduced ankle (SMD=-1.66) and tibial (SMD=-0.63) range of motion. Custom FOs, however, unfavorably affected the running economy (SMD=-0.25) and perceived exertion (SMD=0.20).
SIGNIFICANCE
Although FOs have been reported to have some positive biomechanical effects in healthy populations without musculoskeletal impairments or running-related issues, they need to be optimized and generalized to achieve better running performance and prevent injury.

Meta-Analysis
BACKGROUND
This study evaluates the clinical outcomes of contemporary total ankle arthroplasty (TAAs) to primarily establish the current benefits and risks to facilitate informed decision making to secondarily establish if improvements are seen between subsequent generations of implants, bearing philosophy, and associated surgical technique.
METHODS
A systematic review and meta-analysis of published data from January 2000 to January 2020 was conducted following PRISMA guidelines.
INCLUSION CRITERIA
English language papers, adult population, ≥20 ankles with a minimum follow up ≥24 months, pre- and post-operative functional scores available. Ankle implants were characterised by generations, which were determined from the original studies and confirmed based on literature set definitions.
RESULTS
A total of 4642 TAAs in 4487 patients from 51 studies were included. The mean age was 61.9-years and follow up 57.8-months. Overall, 10-year survivorship rates were 77.63 %, with mobile bearing designs showing a small but significant advantage. Improved survivorship favoured the most modern implants at both two (p < 0.05), and 10-years (p < 0.01). The relative risk of a complication occurring improved with the evolution of implants e.g., nerve injury, and post-operative complications such as fracture, wound complications (e.g., dehiscence or heamatoma) and radiological abnormalities (e.g., radiolucencies, heterotopic bone formation and aseptic loosening). However, surgical site infection, and intra-operative fracture rates remain implant independent.
CONCLUSIONS
Modern TAA offers improved survivorship, even with a trend to lower mean implantation age, similar complexity and ever changing indications. It would appear that implant evolution has reduced risks, especially those associated with revision, without affecting functional outcomes.
