Background: Chronic ankle instability (CAI) is a common and highly disabling condition. Although several studies have evaluated and analyzed prevention and treatment strategies for CAI, an unbiased and systematic synthesis of evidence is required to provide the most powerful and comprehensive evidence-based measures for the its prevention and treatment of CAI. This study aimed to synthesize evidence from the existing literature addressing the treatment and prevention of CAI.

Methods: The PubMed, Embase, Cochrane, and Web of Science databases were systematically searched for relevant studies from inception to December 12, 2023. Data on effect sizes and corresponding 95 % confidence intervals for selected intervention measures were extracted. Systematic reviews were assessed for quality of included studies using a measurement tool (i.e., "AMSTAR 2").

Results: In total, 37 studies were included, among which 21 (57 %) were of high or moderate quality. Strong evidence suggested that lower weight (P < 0.001), lower body mass index (P = 0.002), and non-stability defects (P = 0.04) significantly reduced the risk of developing CAI. Strong evidence supported exercise and moderate evidence supported manual therapy, acupuncture, and surgery for improving CAI. Additionally, external support plays an active role in the treatment process of CAI.

Conclusion: This is the first study synthesizing evidence supporting interventions for the treatment and prevention of CAI. Low body weight and body mass index were effective preventive measures against CAI. Exercise, manual therapy, acupuncture, and surgery can improve ankle function in patients with CAI. Plantar sensory treatment and neuromuscular training may be good therapeutic options for patients with CAI.

Introduction: Ledderhose disease (plantar fibromatosis) is a benign and progressive proliferative disorder of the plantar fascia that forms fixed and painful nodules within the fascia, causing functional disability and decreased quality of life.

Methods: we conducted a narrative review using Pubmed (https://pubmed.ncbi.nlm.nih.gov/) and searched for the terms "Ledderhose disease" "plantar fibromatosis" "Ledderhose disease treatment" "plantar fibromatosis treatment" with further focused searches in Pubmed to supplement information regarding each intervention.

Results: many non-surgical therapeutic strategies are used in managing symptoms. These include pharmacological and non-pharmacological treatment options. Surgical treatment is employed when these therapies are not able to control the symptoms.

Conclusion: understanding and exploring effective treatment modalities for Ledderhose disease (LD) is important in improving the functional disability and quality of life. This review aims to showcase a general outline of the condition and illustrate the present treatments used to manage the disease.

Introduction: Individuals with pes planus may have alterations in talar cartilage thickness due to changes in lower extremity alignment. The aim of this study was to measure the talar cartilage thickness of subjects with pes planus and compare the results with those of healthy controls. Another aim of the present study was to evaluate its relationship with anthropometric foot parameters.

Methods: This cross-sectional study included 48 individuals (16 males and 32 females) in the pes planus group and 48 individuals in the healthy control group (14 males and 34 females) based on the Navicular Drop (ND) test and the Foot Posture Index (FPI). Talar cartilage thickness (TCT) was measured with ultrasound. Anthropometric foot parameters of the individuals, such as foot length and foot width, were evaluated using a podoscope.

Results: TCT was higher in participants with pes planus compared to the control group (dominant side, p = 0.006; non-dominant side, p = 0.002). Foot width and length were similar in both groups for the dominant and non-dominant feet (p > 0.05). TCT on the dominant foot was positively correlated with the FPI score (r = 0.205, p = 0.045), ND score (r = 0.297, p = 0.003), foot width (r = 0.244, p = 0.017) and foot length (r = 0.253, p = 0.013). On the other hand, TCT on the non-dominant side was positively correlated with the FPI score (r = 0.235, p = 0.021), ND score (r = 0.363, p < 0.001), foot width (r = 0.270, p = 0.008) and length (r = 0.303, p = 0.003).

Conclusion: The talar cartilage of patients with pes planus seems to be thicker, and this is generally related to body weight, body mass index, foot anthropometrics, and posture characteristics.

Introduction: Total ankle replacement (TAR) is an effective treatment for end-stage osteoarthritis. The aim of this systematic review was to assess the age of patients undergoing TAR in prospective comparative studies. Our hypothesis is that the age reported in most recent papers might be lower than those reported in older papers.

Methods: This systematic review was performed using Pubmed, Scopus, EMBASE and Cochrane databases. Only Level I and II studies dealing with TAR were included. Data regarding demographics, study design, number of cohorts in each study, year of publication and year/years in which surgery was performed were extracted. A two-fold analysis was conducted building groups of patients based on the year of publication and creating 1) two groups (before and after the median year) and 2) three groups (using tertiles) in order to compare age of patients operated in different period of times. A comparison was also performed considering the median year of surgery for patients undergoing TAR.

Results: Overall 59 cohorts (42 studies, published between 1999 and 2023; median year of publication: 2017) were included (6397 ankles, 6317 patients, median age 63 years). The difference between the median age for 27 cohorts published until 2016 (weighted median 63 years; IQR, 62.5-64) and the median age for 32 cohorts published after 2017 (weighted median 63.2 years; IQR, 63-67.8) was not statistically significant (p = 0.09). The division in tertiles did not reveal any significant change in the weighted median age at surgery (T1 (1999-2014; 63.2 years; IQR, 62.8-64.1), T2 (2015-2018; 63 years; IQR,63-63.5) and T3 (2019-2023; 63.2 years; IQR, 62.6-67.8)) over time (p = 0.65). The median age of patients operated between 1999 and 2008 vs 2009 and 2023 (data from 48 cohorts) was not different either (p = 0.12).

Conclusion: According to this review of prospective studies published between 1999 and 2023, the median age for patients undergoing TAR over the last two decades has been 63 years, remaining steady with no significant changes over time.

Level of evidence: Level II - systematic review including Level I and Level II studies.

Background: Clamping along the transsyndesmotic (TS) axis decreases the risk of malreduction when reducing syndesmotic diastasis. We aimed to measure the difference between the TS axis and the axis determined by the newly proposed fluoroscopic incisura tangent (IT) method. The measurements were compared to those between the TS axis and those based on the center-center (CC) and talar dome lateral (TL) methods.

Methods: We analyzed computed tomographic images of 43 normal ankles. The IT view was simulated using a digitally reconstructed radiograph, in which the anterior and posterior fibular incisura tubercles overlapped on the internally rotated anteroposterior view. The interaxis angle between the TS and the axes determined by the IT method was measured on the axial computed tomographic image corresponding to the radiographic image. The same procedure was repeated using the CC and TL methods. The measured values were compared between the three methods using a one-factor analysis of variance. Furthermore, the measurements of the anteverted and retroverted incisurae were compared for each fluoroscopic method.

Results: The mean interaxis angles between the TS were - 0.5 degrees, 6.3 degrees, and - 1.8 degrees for the IT, CC, and TL methods, respectively, with a significantly larger value for the CC method than for the IT and TL methods (P < .001). No significant difference was found in the interaxis angle in the anteverted (-0.1 degrees) and retroverted (-1.0 degrees) incisurae when using the IT method (P = .15). The angles in the retroverted incisurae were larger than those of the anteverted incisurae for the CC and TL methods.

Conclusion: The fluoroscopic IT method accurately estimated the TS axis. The interaxis angles were consistent, regardless of the incisura anatomy. The fluoroscopic method can be used to clamp and fix the syndesmosis along the TS axis.
