Abstract
The last several decades have brought about substantial development in our understanding of the biomolecular pathways associated with chondral disease and progression to arthritis. Within domains relevant to foot and ankle, genetic modification of stem cells, augmentation of bone marrow stimulation techniques, and improvement on existing scaffolds for delivery of orthobiologic agents hold promise in improving treatment of chondral injuries. This review summarizes novel developments in the understanding of the molecular pathways underlying chondral damage and some of the recent advancements within related therapeutics.

Abstract
BACKGROUND As total ankle arthroplasty (TAA) increases in popularity nationwide for the management of end-stage arthritis, it is essential to understand ways to mitigate the risk of infection. Diabetes increases the risk of infection due to compromised immunity and impaired wound-healing mechanisms. However, there is limited research on how diabetic management, inclusive of medications and glucose control, may impact infection risks post-TAA. This study aims to demonstrate the impact of diabetic management on the occurrence of periprosthetic joint infection (PJI) following TAA. METHODS This was a retrospective study of patients who underwent a TAA at a single academic institution from March 2002 to May 2022. Patients with diabetes who developed an intraarticular infection following TAA were propensity score matched (1:3) to diabetic patients who did not. Data collection included demographics, implant types, diabetic medications, and preoperative hemoglobin A1c. PJI was diagnosed based on Musculoskeletal Infection Society (MSIS) criteria. Statistical analyses assessed differences in medication use, glucose control, and infection rates between groups. RESULTS Of the 1863 patients who underwent TAA, 177 patients had a diagnosis of diabetes. The infection rate in patients with diabetes (2.8%) was higher than the total cohort rate (0.8%). Five patients with diabetes developed a PJI at an average of 2.2 months postoperatively. This cohort (n = 5) was compared to propensity score-matched controls (n = 15). There was no significant difference in diabetic medication use. Patients who developed PJI had higher rates of uncontrolled diabetes (60.0% vs. 6.7%) and average A1c levels (7.02% vs. 6.29%) compared to controls. CONCLUSION Our findings suggest that the elevated risk of PJI observed in individuals with diabetes subsequent to TAA may be attributed not solely to the presence of diabetes, but to inadequate glycemic control. Effectively managing blood glucose levels is imperative for achieving favorable outcomes following TAA. LEVEL OF EVIDENCE III.

Abstract
Background Arthroscopic-assisted treatment of ankle fractures has proven useful in the adult population, but little evidence exists for the utilization of arthroscopic-assisted ankle fracture fixation in the pediatric population. The purpose of this systematic review is to examine the management of pediatric ankle fractures using arthroscopy. Methods A systematic review was performed using PubMed, Web of Science, CINAHL, and MEDLINE from database inception to February 22nd, 2023. Inclusion criteria for this systematic review was pediatric population less than age 18, arthroscopic surgery management, and ankle fracture. Results A total of 19 articles (n=30 patients) out of 176 articles met final inclusion criteria with all articles consisting of case reports or case series. The average patient age was 13.8±1.6 years. Sixteen of the patients (53%) had arthroscopic surgery along with an adjunct surgery as indicated, whereas 14 patients (47%) had arthroscopic surgery with or without percutaneous fixation. A high majority of patients demonstrated full range-of-motion and large improvements in function. Conclusions Arthroscopy is used with percutaneous fixation or in adjunct to open approaches for pediatric ankle fracture management with good results. More research is needed to determine the utility of arthroscopy in the management of pediatric ankle fractures.

Abstract
BACKGROUND Despite the questionable validity of online-based physician review websites (PRWs), negative reviews can adversely affect a provider's practice. Several investigations have explored the effect of extremely negative "one-star" reviews across subspecialties such as adult reconstruction, sports medicine, and orthopaedic traumatology; however, to date, no study has explored one-star reviews in foot and ankle surgery. The goal of this study was to characterize factors that contribute to extremely negative, one-star reviews for foot and ankle surgeons on Vitals.com. METHODS A retrospective analysis of negative one-star reviews with corresponding patient complaints for foot and ankle surgeons (both orthopaedic surgeons as well as podiatrists) in the United States. Physicians included were selected within a 10-mile radius of the top ten largest cities in the United States. Data was stratified by patient type (e.g., those receiving surgery and those not undergoing surgical intervention) and binned according to type of patient complaint, as previously described. RESULTS Of the 2645 foot and ankle surgeons identified in our initial query, 13.8% of surgeons contained one-star reviews eligible for analysis. Patient complaints related to bedside manner and patient experience are the causative factors accounting for 41.5% of the one-star reviews of foot and ankle surgeons for nonsurgical-related complaints. Surgical complications and other outcomes-related factors comprised roughly 50% of the complaints related to surgical patients. CONCLUSION In conclusion, complaints related to bedside manner and patient experience are the causative factors accounting for 41.5% of the one-star reviews of foot and ankle surgeons for nonsurgical-related complaints. Surgical complications and other outcomes-related factors comprised roughly half of the complaints related to surgery. This data serves to inform practicing foot and ankle surgeons as to the influences behind patients leaving extremely negative reviews on PRWs. LEVEL OF CLINICAL EVIDENCE IV.

Abstract
SUMMARY Treatment of traumatic critical-sized bone defects remains a challenge for orthopaedic surgeons. Autograft remains the gold standard to address bone loss, but for larger defects, different strategies must be used. The use of 3D-printed implants to address lower extremity trauma and bone loss is discussed with current techniques including bone transport, Masquelet, osteomyocutaneous flaps, and massive allografts. Considerations and future directions of implant design, augmentation, and optimization of the peri-implant environment to maximize patient outcome are reviewed.

Abstract
SUMMARY 3D printing technologies have evolved tremendously over the last decade for uses in orthopaedic surgical applications, including being used to manufacture implants for spine, upper extremity, foot and ankle, oncologic, and traumatic reconstructions. Materials used for 3D-printed orthopaedic devices include metals, degradable and nondegradable polymers, and ceramic composites. There are 2 primary advantages for use of 3D printing technologies for orthopaedics: first, the ability to create complex porous lattices that allow for osseointegration and improved implant stability and second, the enablement of complex geometric designs allowing for patient-specific devices based on preoperative imaging. Given continually evolving technology, and the relatively early stage of the materials and 3D printers themselves, the possibilities for continued innovation in orthopaedics are great.

Abstract
As the number of primary total ankle replacements increases for treatment of end-stage ankle arthritis, failures are also expected to rise. Periprosthetic joint infection is among the causes of failures and has been reported to be as high as 5%. Diagnosis is usually made by a combination of clinical examination findings, imaging, laboratory, and microbiological workup. Management is generally separated into limb salvage or amputation. Limb salvage can be challenging and may involve a single versus staged approach. Options include revision arthroplasty or arthrodesis procedures (ankle versus tibiotalocalcaneal), and a multidisciplinary approach is sought to eradicate infection before definitive management.

Abstract
BACKGROUND Prosthetic substitution of the talus presents a significant challenge to the foot and ankle surgeon. The shear and compressive forces on the talus and its tenuous blood supply lead to high rates of avascular necrosis and eventual talar collapse. The purpose of this systematic review is to evaluate whether total ankle total talus replacement (TATTR) leads to improved clinical and radiographic outcomes with appropriate safety metrics in patients with a history of avascular necrosis or significant trauma. METHODS We searched the concepts of talus, prosthesis, and arthroplasty in MEDLINE (PubMed), Embase (Elsevier), CINAHL Complete (EBSCOhost), and Scopus (Elsevier) from the database's inception through March 9, 2023. Inclusion Criteria were 1) previous trauma to the talus, 2) post-traumatic arthritis to the tibiotalar joint, 3) avascular necrosis of talus, 4) multiple failed prior interventions, 5) degenerative osteoarthritis to the tibiotalar joint, and 6) inflammatory arthropathy to tibiotalar joint. Patients less than 18 years of age and manuscripts in non-English languages were excluded. RESULTS Of the 7625 references, 16 studies met the inclusion criteria, yielding data from 136 patients (139 ankles). The studies varied in design, with case reports and retrospective case series being predominant. The overall weighted average modified Coleman Methodology Score (mCMS) was 70.4 out of 100, indicating moderate flaws in study design that may be subject to various forms of bias and possible confounders. Demographics showed a diverse range of etiologies, with alumina ceramic being the primary prosthesis material. Functional scores demonstrated improvements in dorsiflexion and plantarflexion, although patient-reported outcome measures (PROs) were inconsistently reported. Complications included fractures, heterotopic ossification, prolonged wound healing, and infections. Revision details were sparsely reported. CONCLUSION TATTR is a promising treatment modality for improving short-term functional outcomes for patients with avascular necrosis or trauma-related issues. However, this systematic review underscores the need for standardized reporting, longer-term follow-ups, and further research to establish the procedure's efficacy and safety, particularly in comparison to other treatment modalities.

Abstract
Cartilage damage presents a significant clinical challenge due to its intrinsic avascular nature which limits self-repair. Addressing this, our study focuses on an alginate-based bioink, integrating human articular cartilage, for cartilage tissue engineering. This novel bioink was formulated by encapsulating C20A4 human articular chondrocytes in sodium alginate, polyvinyl alcohol, gum arabic, and cartilage extracellular matrix powder sourced from allograft femoral condyle shavings. Using a 3D bioprinter, constructs were biofabricated and cross-linked, followed by culture in standard medium. Evaluations were conducted on cellular viability and gene expression at various stages. Results indicated that the printed constructs maintained a porous structure conducive to cell growth. Cellular viability was 87% post printing, which decreased to 76% after seven days, and significantly recovered to 86% by day 14. There was also a notable upregulation of chondrogenic genes, COL2A1 (p = 0.008) and SOX9 (p = 0.021), suggesting an enhancement in cartilage formation. This study concludes that the innovative bioink shows promise for cartilage regeneration, demonstrating substantial viability and gene expression conducive to repair and suggesting its potential for future therapeutic applications in cartilage repair.

Abstract
BACKGROUND The utilization of total ankle arthroplasty (TAA) for managing severe ankle osteoarthritis has become increasingly common, leading to a higher occurrence of revision TAA procedures because of failure of primary TAA. This study aims to examine the clinical results associated with revision TAA using the INBONE II system. Given the growing number of TAA revision procedures and a focus on motion-preserving salvage options, we evaluated our early experience with revision TAA. METHODS A retrospective analysis was conducted on a group of 60 presumed noninfected patients who underwent revision TAA with the INBONE II system. Detailed information was collected on patient demographics, implant characteristics, concurrent procedures, and complications. The implant survival was estimated using Kaplan-Meier analysis. RESULTS The study revealed high complication rates but generally fair clinical outcomes for revision TAA using the INBONE II system. Complications were observed in 22 patients (36.7%), including persistent pain (n = 6), nerve injury/impingement (n = 5), infection (n = 3), fracture (n = 3), implant failure (n = 3), impaired wound healing (n = 2), and osteolysis (n = 3). The 3-year survivorship rate from reoperation was 92.0% (82.7%-100.0%) whereas the 3-year survivorship rate from major complications was 90.4% (80.8%-100.0%). CONCLUSION We report high complication rates but generally fair clinical results for revision TAA utilizing the INBONE II system. LEVEL OF EVIDENCE Level IV, retrospective case series study.

Abstract
BACKGROUND The study investigates the connection between academic productivity and industry earnings in foot and ankle orthopedic surgery fellowships. Utilizing metrics like the H-index and Open Payments Database (OPD) data, it addresses a gap in understanding the relationship between scholarly achievements and financial outcomes, providing a basis for further exploration in this specialized medical field. AIM To elucidate the trends between academic productivity and industry earnings across foot and ankle orthopedic surgery fellowship programs in the United States. METHODS This study is a retrospective analysis of the relationship between academic productivity and industry earnings of foot and ankle orthopedic surgery fellowships at an individual faculty and fellowship level. Academic productivity was defined via H-index and recorded from the Scopus website. Industry earnings were recorded from the OPD. RESULTS Forty-eight foot and ankle orthopedic surgery fellowships (100% of fellowships) in the United States with a combined total of 165 physicians (95.9% of physicians) were included. Mean individual physician (n = 165) total life-time earnings reported on the OPD website was United States Dollar (USD) 451430.30 ± 1851084.89 (range: USD 25.16-21269249.85; median: USD 27839.80). Mean physician (n = 165) H-index as reported on Scopus is 14.24 ± 12.39 (range: 0-63; median: 11). There was a significant but weak correlation between individual physician H-index and individual physician total life-time earnings (P < 0.001; Spearman's rho = 0.334) and a significant and moderate positive correlation between combined fellowship H-index and total life-time earnings per fellowship (P = 0.004, Spearman's rho = 0.409). CONCLUSION There is a significant and positive correlation between academic productivity and industry earnings at foot and ankle orthopedic surgery fellowships in the United States. This observation is true on an individual physician level as well as on a fellowship level.

Abstract
BACKGROUND Hallux valgus is a common condition with a complex etiology resulting in numerous treatment options. Recurrence of the deformity can occur following correction. Surgical technique and possibly also postoperative care play a role in reducing recurrence rates. This article highlights a postoperative surgical dressing technique which allows for semirigid support during the immediate postoperative period. METHODS A wooden tongue depressor placed along the medial border of the hallux comprises the primary support for the dressing. The rigidity of the tongue depressor allows for the hallux to be drawn toward the depressor, encouraging neutral alignment of the hallux. Dressings are removed 2 weeks postoperatively, with new dressings applied in similar fashion and maintained in place until 6 weeks postoperatively. RESULTS Based upon our observations, our surgical dressing technique provides sufficient support following hallux valgus correction surgery while being straightforward to replicate without the need for frequent dressing changes. The dressing materials are of negligible cost and are typically readily available. No associated wound complications have been observed. CONCLUSIONS We present an easily replicable and affordable option for postoperative hallux valgus correction surgical dressings. LEVELS OF EVIDENCE Level V: Expert Opinion.

Abstract
BACKGROUND The COVID-19 pandemic caused notable shifts in healthcare behavior, influenced by remote work policies. This study examines the impact of Work from Home (WFH) policies on public interest in ankle-related orthopaedic surgeries, utilizing Google search trends. Understanding these trends is crucial for healthcare providers, enabling them to adapt services and communication to evolving patient needs during challenging times. OBJECTIVE To comprehend variations in search volume and trends for ankle-related queries due to WFH policies during the COVID-19 pandemic. METHODS Ankle-related terms accessible to laypersons were analyzed using Google Trends data from March 2018 to March 2022 in the United States. Data were divided into pre-pandemic (March 2018-March 2020) and post-pandemic (March 2020-March 2022) periods. Weekly search interest data for 20 terms were analyzed using a Mann-Whitney U test. The study aimed to identify significant changes in search interest, providing insights into public information-seeking behavior concerning ankle surgeries. RESULTS Among the 20 terms analyzed, 11 exhibited significant changes. Ankle arthritis and ankle bursitis showed increased interest, suggesting heightened concern during the pandemic. Conversely, post-pandemic interest decreased for terms 9 terms, including ankle pain and ankle tendonitis, indicating reduced worry. Moderate declines were noted for ankle gout, Achilles tendonitis, and heel bursitis, reflecting shifting patient priorities. Some terms, including ankle fracture and ankle arthroplasty, showed stable information-seeking behavior despite the pandemic. CONCLUSIONS The study underscores the nuanced impact of WFH policies on public interest in ankle-related orthopaedic surgeries. Varied search trends highlight changing patient concerns. Healthcare providers can use these insights to tailor services effectively, meeting evolving patient needs and enhancing communication strategies.

Abstract
Hallux valgus deformity (HVD) involves subluxation of the first metatarsophalangeal joint. While HVD is primarily considered a forefoot condition, midfoot instability may play a significant role in its development and severity. However, very few studies have placed a heavy emphasis on studying this phenomenon. Therefore, this review had a particular focus on understanding midfoot instability based on weightbearing imaging assessments of the TMT joint. This review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and searched five databases for studies on midfoot instability in HVD patients. The severity of HVD was defined by hallux valgus angle (HVA) and distal metatarsal articular angle (DMAA). Data was extracted, and articles were graded using the Methodological Index for Non-Randomized Studies (MINORS). Of 547 initially retrieved articles, 23 met the inclusion criteria. Patients with HVD showed higher HVA and DMAA on weightbearing radiographs (WBRG) and weightbearing computed tomography (WBCT) compared to healthy individuals. Midfoot instability was assessed through intermetatarsal angle (IMA) and tarsometatarsal angle (TMT angle). Patients with HVD exhibited greater IMA and TMT angles on both WBRG and WBCT. This review highlights the importance of weightbearing imaging assessments for midfoot instability in HVD. IMA and TMT angles can differentiate between healthy individuals and HVD patients, emphasizing the significance of midfoot assessment in understanding HVD pathology. These findings validate the limited evidence thus far in the literature pertaining to consistent midfoot instability in HVD patients and are able to provide ample reasoning for physicians to place a larger emphasis on midfoot imaging when assessing HVD in its entirety.

Abstract
BACKGROUND Although many patients with posttraumatic ankle arthritis are of a younger age, studies evaluating the impact of age on outcomes of primary total ankle arthroplasty (TAA) have revealed heterogenous results. The purpose of the present study was to determine the effect of age on complication rates and patient-reported outcomes after TAA. METHODS We retrospectively reviewed the records of 1,115 patients who had undergone primary TAA. The patients were divided into 3 age cohorts: <55 years (n = 196), 55 to 70 years (n = 657), and >70 years (n = 262). Demographic characteristics, intraoperative variables, postoperative complications, and patient-reported outcome measures were compared among groups with use of univariable analyses. Competing-risk regression analysis with adjustment for patient and implant characteristics was performed to assess the risk of implant failure by age group. The mean duration of follow-up was 5.6 years. RESULTS Compared with the patients who were 55 to 70 years of age and >70 years of age, those who were <55 years of age had the highest rates of any reoperation (19.9%, 11.7%, and 6.5% for the <55, 55 to 70, and >70-year age groups, respectively; p < 0.001), implant failure (5.6%, 2.9%, and 1.1% for the <55, 55 to 70, and >70-year age groups, respectively; p = 0.019), and polyethylene exchange (7.7%, 4.3%, and 2.3% for the <55, 55 to 70, and >70-year age groups, respectively; p = 0.021). Competing-risk regression revealed a decreased risk of implant failure for patients who were >70 of age compared with those who were <55 years of age (hazard ratio [HR], 0.21 [95% confidence interval (CI), 0.05 to 0.80]; p = 0.023) and for patients who were 55 to 70 years of age compared with those who were <55 years of age (HR, 0.35 [95% CI, 0.16 to 0.77]; p = 0.009). For all subscales of the Foot and Ankle Outcome Score (FAOS) measure except activities of daily living, patients who were <55 years of age reported the lowest (worst) mean preoperative and postoperative scores compared with those who were 55 to 70 years of age and >70 years of age (p ≤ 0.001). Patients who were <55 years of age had the highest mean numerical pain score at the time of the latest follow-up (23.6, 14.4, 12.9 for the <55, 55 to 70, and >70-year age groups, respectively; p < 0.001). CONCLUSIONS Studies involving large sample sizes with intermediate to long-term follow-up are critical to reveal age-related impacts on outcomes after TAA. In the present study, which we believe to be the largest single-institution series to date evaluating the effect of age on outcomes after TAA, younger patients had higher rates of complications and implant failure and fared worse on patient-reported outcome measures.

Abstract
BACKGROUND The purpose of this study is to develop a simple and reproducible bending model that is compatible with a wide range of orthopaedic fixation devices and 3D printed spacers. METHODS A robust 4-point bending model was constructed by securing sawbones blocks with different orthopaedic fixation device constructs. Stress strain curves derived from a fundamental mechanics model were used to assess the effect of bone density, type of hardware (staple vs intramedullary beam), the use of dynamic compression, orientation of staples (dorsal vs plantar), and the use of 3D printed titanium spacers. FINDINGS The high throughput 4-point bending model is simple enough that the methods can be easily repeated to assess a wide range of fixation methods, while complex enough to provide clinically relevant information. INTERPRETATIONS It is recommended that this model is used to assess a large initial set of fixation methods in direct and straightforward comparisons.

Abstract
BACKGROUND The literature demonstrating positive outcomes after total ankle arthroplasty (TAA) is mounting. However, the long-term outcomes of TAA (≥ 10 years) remain minimally reported. The purpose of this systematic review and meta-analysis was to evaluate outcome metrics over multiple TAA studies with greater than 10 years of average follow-up. METHODS TAA studies were searched in Medline, Embase, and Scopus from the date of inception to September 12, 2022. Inclusion criteria included 1) studies of patients that underwent uncemented TAA, and 2) studies with an average follow-up time of at least ten years. Manuscripts in non-English languages and isolated abstracts were excluded. We collected American Orthopaedic Foot and Ankle Score (AOFAS) and Visual Analog Scale (VAS) scores from the included studies for pooled meta-analysis. Due to the varying definition of survivability between studies, this metric was not assessed in our final evaluation. RESULTS Our data included approximately 3651 patients (3782 ankles). Of the 25 studies with an average follow-up of 10 years included in the systematic review, 5 provided pre- and post-operative AOFAS means and 5 provided pre- and post-operative VAS means with associated measures of variability and were included in our meta-analysis. The weighted mean difference between pre-and post-operative AOFAS and VAS scores was -40.36 (95% CI -47.24 to -33.47) and 4.52 (95% CI: 2.26-6.43), respectively. The risk of bias was low to moderate for the included studies. CONCLUSION Outcomes following TAA are favorable and indicate patient-reported outcome improvement over long-term follow-up. However, a significant amount of heterogeneity exists between studies. Future, prospective, randomized research should focus on standardizing outcome measures, survivorship, and complication reporting methodologies to allow for pooled meta-analyses of these important outcome metrics.

Abstract
BACKGROUND Despite substantial increase in total ankle arthroplasty (TAA) nationwide, there are few studies comparing flat-cut vs chamfer-cut talar systems in TAA with regard to radiographic aseptic loosening rates of the implant. METHODS This retrospective study included 189 Salto-Talaris TAA and 132 INBONE II primary TAA with a minimum 1-year follow-up. Patient characteristics were obtained including gender, age at surgery, body mass index (BMI), smoking status, primary diagnosis, surgical time, and the presence of diabetes. Radiographic evidence for aseptic loosening was assessed. Statistical analysis was performed for comparison in outcomes between Salto-Talaris and INBONE II. RESULTS The mean age of the study population was 63.5 ± 9.8 years at surgery. Mean follow-up was 4.9 ± 3.0 years. Radiographic aseptic loosening of the tibial implant showed no significant difference between the 2 groups: Salto-Talaris, 18%, and INBONE II, 18.9% (P = .829). Aseptic loosening of the talar implant also showed no significant difference between the 2 groups: Salto-Talaris, 1.6%, and INBONE II, 1.5% (P = .959). No variables, including the implant type, were found to contribute to the aseptic loosening rate of either the tibia or talus. CONCLUSION In our cohort, we observed no difference in radiographic implant aseptic loosening between Salto-Talaris and INBONE II systems. LEVEL OF EVIDENCE Level IV, retrospective case series study.

Abstract
Platelet-rich plasma (PRP) is an autologous serum containing higher concentrations of platelets and growth factors above normal blood. The process of obtaining PRP involves the extraction of blood from the patient which is then centrifuged to obtain a concentrated suspension of platelets. PRP continues to evolve as a potential treatment modality with many applications in orthopaedic surgery. The therapeutic components of PRP possess numerous theoretical regenerative properties. The present manuscript outlines how PRP is prepared, noting the tremendous variability between preparation protocols. Given the growing body of evidence examining the use of PRP in pathologies of the foot and ankle, we assess its efficacy as it relates to our field. Specifically, we evaluate the literature in the past five years regarding the role of PRP in treating plantar fasciitis, Achilles tendinopathy, insertional Achilles tendinitis, Achilles tendon ruptures, osteochondral lesions of the talus, hallux rigidus, and ankle osteoarthritis.

Abstract
BACKGROUND Infection is a serious complication of primary total ankle arthroplasty (TAA) and can lead to implant failure and revision surgery. Various demographic, comorbidity, and surgical factors have been associated with an increased risk of infection. However, the evidence base remains limited, and further research is needed regarding infection in TAA. This study aims to analyze risk factors of infection and explore outcomes following infected TAA. METHODS A retrospective cohort study was conducted using data from a single institution from 2002 to 2022. Patients who underwent primary TAA and had subsequent infection were identified through annual registry surveillance and matched using propensity score matching (PSM) based on various demographic, comorbidity, and surgical factors. Demographics were compared between the matched groups using Mann-Whitney U test and Fisher exact test. The outcomes following infection were identified and summarized using descriptive statistics. RESULTS A total of 1863 patients who underwent primary TAA were identified, and 19 were diagnosed with an infection. The identifiable overall infection rate was 1.0%. After PSM, there were no significant differences in the difference in age, gender, BMI, and smoking status between the infected and control cohort. There was a statistically significant increase in the rate of diabetes in the infected cohort. The subsequent surgical intervention resulted in limb salvage in 18 (94.7%) cases. Out of the total number of cases, 2-stage revision to total ankle replacement was performed in 7 cases, whereas revision to arthrodesis and isolated polyethylene exchange were each carried out in 4 cases. One patient had to undergo amputation; however, at the time of the most recent follow-up, all patients were found to be free of infection. CONCLUSION This study demonstrated high rates of a history of smoking and diabetes in the infected TAA cohort. The diabetes rate in the infected group was significantly higher than the noninfected controls. Two-stage revision to total ankle replacement was performed in 7 cases, and revision to arthrodesis and isolated polyethylene exchange were each carried out in 4 cases. Overall, a high rate of limb salvage was reported. LEVEL OF EVIDENCE Level III, case-control study.

Abstract
BACKGROUND As total talus replacement (TTR) grows in popularity as a salvage option for talar collapse, a critical evaluation of the complications associated with this procedure is indicated. METHODS In this review of the literature, we present a patient report and provide a review of several complications seen after TTR, including ligamentous instability, infection, and adjacent joint osteoarthritis, which we have encountered in our practice. RESULTS Total talus replacement has the potential to reduce pain and preserve range of motion. However, the treating surgeon must be cognizant of the variety of adverse outcomes. We have presented cases of potential devastating complications from our own clinical experience and the literature. CONCLUSIONS In conclusion, TTR may have utility in the properly selected patient with end-stage talar collapse, but implant composition, indications, and patient demographic variables complicate the interpretation of the literature.Levels of Evidence: Level III.

Abstract
The first metatarsophalangeal (MTP) joint is a frequently loaded joint, handling loads up to 90% of bodyweight. First MTP arthrodesis is a frequently performed procedure designed to improve pain in patients with degenerative MTP joint disease. There are a wide variety of fixation constructs for this procedure without consensus on the most effective method. The purpose of this study was to compare the biomechanical integrity of various constructs utilized for first MTP arthrodesis. A systematic review of the literature was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed, CINAHL, MEDLINE, and Web of Science databases were searched from inception to 18 June 2023. Articles discussing the biomechanics of first MTP arthrodesis constructs were included. A total of 168 articles were retrieved. A total of 20 articles involving 446 cadaveric and synthetic bone constructs were included in the final review. Of the six articles comparing dorsal plating with compression screws to crossed interfragmentary screws, five found that dorsal plating had significantly higher stiffness. All three studies assessing shape-memory staples found them to be significantly less stable than crossed screws or dorsal plates alone. Both studies evaluating fully threaded screws found them to be stronger than crossed cancellous screws. Wedge resections have been shown to be 10 times stronger than standard planar or conical excision. Dorsal plating with compression screws is the gold standard for MTP arthrodesis. However, more research into newer methods such as fully threaded screws and wedge resections with an increased focus on translation to clinical outcomes is needed.

Abstract
Purpose The purpose of this study was to compare bone marrow stimulation using micro-computed tomography (micro-CT) analysis of an abrasion arthroplasty technique, drilling k-wire technique, traditional microfacture awl, or a microdrill instrument for subchondral bone defects. Methods Eleven cadaveric distal femoral specimens were obtained and divided into 3 common areas of osteochondral defect: trochlea and weightbearing portions of the medial and lateral femoral condyles. Each area of interest was then denuded of cartilage using a PoweRasp and divided into quadrants. Each quadrant was assigned either a 1.6 mm Kirschner wire (k-wire), 1.25 mm microfracture awl, 1.5 mm fluted microdrill, PowerPick, or a curette (abrasion arthroplasty) to create 4 channels into the subchondral bone sing the same instrument. Subchondral bone and adjacent tissue areas were then evaluated using micro-CT to analyze adjacent bone destruction and extension into the bone marrow. Results Overall, there was a significantly decreased area of bone destruction or compression using the microdrill (0.030 mm) as compared to the microfracture awl (0.072 mm) and k-wire (0.062 mm) (P < .05). Within the trochlea and the medial femoral condyle, there was significantly decreased bony compression with the microdrill as compared to the awl and k-wire (P < .05); however, when stratified, this was not significant among the lateral femoral condylar samples (P = .08). Conclusion Bone marrow stimulation causes bony compression that may negatively impact subchondral bone and trabecular alignment. It is important to understand which tools used for bone marrow stimulation cause the least amount of damage to the subchondral bone. Clinical Relevance This study demonstrates the decreased subchondral bony defects seen with the microdrill versus the traditional microfracture awl indicating that when performing bone marrow stimulation, the microdrill may be a less harmful tool to the subchondral bone.

Abstract
Background Since the Physician Payments Sunshine Act in 2010, a substantial body of work has explored the supplemental income received by physicians to understand trends in industry payments and investigate sources of bias. To date, no study has examined how various fellowship characteristics impact industry earning levels at foot and ankle orthopaedic surgery fellowships. The purpose of this study is to examine the various fellowship and faculty-specific variables in correlation with industry earnings in foot and ankle orthopaedic surgery fellowships. Methods This study is a retrospective analysis of foot and ankle orthopaedic surgery fellowships and respective faculty along with various fellowship characteristics in correlation to industry lifetime earning levels as of March 2023. Industry total lifetime earnings represent income directly paid to physicians, is not part of the physician's salary, and does not include any research grants or funding. Lifetime earnings represent all years recorded on the Open Payments Database website (2015-2021). Results There are 165 faculty physicians and 48 programs with complete data out of all foot and ankle orthopaedic surgery fellowship programs in the United States. The mean fellowship H-Index per fellowship was 48.94 ± 38.92, and the mean fellowship lifetime earning was $1 551 791.66 ± $4 136 091.64. There was no significant association between fellowship lifetime earnings and Newsweek ranking of fellowship-affiliated hospitals (P = .906), Doximity ranking of fellowship-affiliated residencies (P = .703), and region of the United States (P = .126). There was a statistically significant increase in total lifetime earnings in programs with 4 fellows as compared to 1 fellow (P = .035). Conclusion There was no statistically significant correlation between a variety of foot and ankle fellowship-specific factors and lifetime industry earnings, aside from increased earnings in programs having 4 fellows. Prestige factors, such as Doximity and Ranked Hospital Newsweek List rank, as well as region of the United States is not associated with industry earnings.

Abstract
BACKGROUND Legislation in the United States has been enacted to reduce opioid overuse and abuse in the setting of the opioid epidemic, and a notable target has been opioid overprescription. However, the impact of this legislation on elective foot and ankle surgery is largely unknown. The purpose of this study was to evaluate the impact of opioid-limiting legislation on opioid prescribing in elective foot and ankle surgery. METHODS The 90-day perioperative opioid prescription filling in oxycodone 5-mg equivalents was identified in all patients 18 years of age and older undergoing nontrauma, nonarthroplasty foot and ankle surgery from 2010 to 2019 using a commercial database. States with and without legislation were identified, and opioid prescription filling before and after the legislation were tabulated. Unadjusted and adjusted analyses were performed to evaluate the impact of time and state legislation on perioperative opioid prescribing in this patient population. RESULTS Initial and cumulative opioid prescribing decreased significantly from 2010 to 2019 (39 vs 35.7 initial and 98.1 vs 55.7 cumulative). States with legislation had larger and more significant reductions in initial and cumulative opioid prescribing compared with states without legislation over similar time frames (41.6 to 35.1 with legislation vs 40.6 to 39.1 without legislation initial prescription filling volume and 87.7 to 62.8 vs 88.6 to 74.1 cumulative prescription filling volume). CONCLUSION State legislation and time have been associated with large, clinically relevant reductions in 90-day perioperative cumulative opioid prescription filling, although reductions in initial opioid prescription filing have remained low. These results encourage states without legislation to enact restraints to reduce the opioid epidemic. LEVELS OF EVIDENCE Level III: Retrospective, prognostic cohort study.

Abstract
Background Artificial intelligence (AI) platforms, such as ChatGPT, have become increasingly popular outlets for the consumption and distribution of health care-related advice. Because of a lack of regulation and oversight, the reliability of health care-related responses has become a topic of controversy in the medical community. To date, no study has explored the quality of AI-derived information as it relates to common foot and ankle pathologies. This study aims to assess the quality and educational benefit of ChatGPT responses to common foot and ankle-related questions. Methods ChatGPT was asked a series of 5 questions, including "What is the optimal treatment for ankle arthritis?" "How should I decide on ankle arthroplasty versus ankle arthrodesis?" "Do I need surgery for Jones fracture?" "How can I prevent Charcot arthropathy?" and "Do I need to see a doctor for my ankle sprain?" Five responses (1 per each question) were included after applying the exclusion criteria. The content was graded using DISCERN (a well-validated informational analysis tool) and AIRM (a self-designed tool for exercise evaluation). Results Health care professionals graded the ChatGPT-generated responses as bottom tier 4.5% of the time, middle tier 27.3% of the time, and top tier 68.2% of the time. Conclusion Although ChatGPT and other related AI platforms have become a popular means for medical information distribution, the educational value of the AI-generated responses related to foot and ankle pathologies was variable. With 4.5% of responses receiving a bottom-tier rating, 27.3% of responses receiving a middle-tier rating, and 68.2% of responses receiving a top-tier rating, health care professionals should be aware of the high viewership of variable-quality content easily accessible on ChatGPT.

Abstract
BACKGROUND As total ankle arthroplasty (TAA) is increasingly performed in younger individuals in the United States, the aim of this study was to analyze TAA outcomes and complications by age. METHODS A total of 1619 primary and revision TAAs from 2012 to 2020 were collected and included from the National Surgical Quality Improvement Program. Patients were stratified by age into those younger than 55 years, between 55 and 70 years, and older than 70 years. Demographics, medical comorbidities, American Society of Anesthesiology Physical Classification (ASA) class, operative time, 30-day complications, and comorbid conditions were compared by univariable analysis. Multivariable analysis was used to analyze readmission rates, reoperation rates, operative time, and hospital length of stay. RESULTS Patients younger than 55 years were found to have a significantly longer operative time compared to patients older than 70 years of age or between 55 and 70 years (P < .001, P = .034). Patients older than 70 years were found to have a significantly longer hospital stay (P < .001) and a greater risk of discharging to a nonhome location (P < .001). By multivariable analysis, patients 55 to 70 have a statistically lower risk of readmission compared to the other 2 cohorts (P = .043). No difference in postoperative complications was demonstrated between the different groups. CONCLUSIONS As the incidence of total ankle arthroplasty increases across all ages, it is important to understand specific perioperative risks for each age group. Younger patients tended to have longer surgeries and higher body mass indexes (BMIs). Patients aged 55 to 70 years had the lowest risks for perioperative complications. Patients greater than 70 years were at risk for longer hospital stays and discharge to nonhome locations. There were no differences in postoperative complications by age.

Abstract
Charcot neuroarthropathy (CN) is a rare but serious sequela of diabetes and other diseases that cause peripheral neuropathy. It is most commonly characterized by degeneration of the foot and/or ankle joints leading to progressive deformity and altered weight-bearing. If left untreated, the deformities of CN lead to ulceration, infection, amputation, and even death. Because of the associated peripheral neuropathy and proprioception deficits that accompany CN, patients typically do not perceive the onset of joint destruction. Moreover, in the hands of the untrained clinician, the initial presentation of CN can easily be mistaken for infection, osteoarthritis, gout, or inflammatory arthropathy. Misdiagnosis can lead to the aforementioned serious sequelae of CN. Thus, an early accurate diagnosis and off-loading of the involved extremity, followed by prompt referral to a specialist trained in the care of CN are crucial to prevent the late-term sequelae of the disease. The purpose of this article was to create an opportunity for enhanced understanding between orthopedic surgeons and emergency physicians, to improve patient care through the optimization of diagnosis and early management of CN in the emergent setting.

Abstract
BACKGROUND The first stage of fracture healing consists of hematoma formation with recruitment of proinflammatory cytokines and matrix metalloproteinases. Unfortunately, when there is an intra-articular fracture, these inflammatory mediators are not retained at the fracture site, but instead, envelop the healthy cartilage of the entire joint via the synovial fluid fracture hematoma (SFFH). These inflammatory cytokines and matrix metalloproteinases are known factors in the progression of osteoarthritis and rheumatoid arthritis. Despite the known inflammatory contents of the SFFH, little research has been done on the effects of the SFFH on healthy cartilage with regard to cell death and alteration in gene expression that could lead to posttraumatic osteoarthritis (PTOA). METHODS SFFH was collected from 12 patients with intraarticular ankle fracture at the time of surgery. Separately, C20A4 immortalized human chondrocytes were 3-dimensionally cultured to create scaffold-free cartilage tissue analogs (CTAs) to simulate healthy cartilage. Experimental CTAs (n = 12) were exposed to 100% SFFH for 3 days, washed, and transferred to complete media for 3 days. Control CTAs (n = 12) were simultaneously cultured in complete medium without exposure to SFFH. Subsequently, CTAs were harvested and underwent biochemical, histological, and gene expression analysis. RESULTS Exposure of CTAs to ankle SFFH for 3 days significantly decreased chondrocyte viability by 34% (P = .027). Gene expression of both COL2A1 and SOX9 were significantly decreased after exposure to SFFH (P = .012 and P = .0013 respectively), while there was no difference in COL1A1, RUNX2, and MMP13 gene expression. Quantitative analysis of Picrosirius red staining demonstrated increased collagen I deposition with poor ultrastructural organization in SFFH-exposed CTAs. CONCLUSION Exposure of an organoid model of healthy cartilage tissue to SFFH after intraarticular ankle fracture resulted in decreased chondrocyte viability, decreased expression of genes regulating normal chondrocyte phenotype, and altered matrix ultrastructure indicating differentiation toward an osteoarthritis phenotype. CLINICAL RELEVANCE The majority of ankle fracture open reduction and internal fixation does not occur immediately after fracture. In fact, typically these fractures are treated several days to weeks later in order to let the swelling subside. This means that the healthy innocent bystander cartilage not involved in the fracture is exposed to SFFH during this time. In this study, the SFFH caused decreased chondrocyte viability and specific altered gene expression that might have the potential to induce osteoarthritis. These data suggest that early intervention after intraarticular ankle fracture could possibly mitigate progression toward PTOA.

Abstract
Background Suture button fixation of syndesmotic injuries allows for more physiologic motion of the ankle joint while maintaining adequate reduction and may avoid the need for additional surgeries, given the lower risk of syndesmotic diastasis and implant failure. Few studies have examined the optimal number and configuration of suture buttons for syndesmotic disruption. The purpose of this systematic review and meta-analysis is to compare different suture button configurations from the cadaveric literature and to assess their relative effect on the stability of the syndesmotic reduction and functional movement of the ankle. Methods A literature search in the databases MEDLINE via PubMed, Embase via Elsevier, Scopus via Elsevier, and SPORTDiscus via EBSCO were searched through December 2022 to identify studies related to cadaveric modeling of the syndesmosis. Only cadaveric studies with suture button fixation and studies in English were included. The quality of cadaveric studies was assessed using the Quality Assessment for Cadaveric Studies (QUACS) tool. Revman 5.3 software was used to perform the meta-analysis. Results The meta-analysis included 5 studies and 86 limbs. The systematic review included 15 studies. When comparing single and double suture button configurations, no difference was found between groups with regard to fibular rotation (MD =-0.9; 95% CI: -2.09 to 0.27; I2=79%; P=0.13) and both groups had similar rotational stability. The double suture button technique did demonstrate less sagittal fibular translation compared to the single suture button (MD =0.48; 95% CI: 0.02-0.94; I2=66%; P=0.04). When comparing two suture buttons in parallel and divergent configurations, studies did not find any differences with regard to strength or stability. Conclusions There were no significant differences in biomechanical parameters when comparing single and double suture button constructs. While single button suture constructs result in minimal fibular rotation, double suture button constructs minimize fibular translation. This review may serve as a guide for clinicians when approaching these injuries.

Abstract
BACKGROUND There is limited data evaluating the effect of obesity on outcomes following total ankle arthroplasty (TAA), especially in adequate sample sizes to detect impacts on patient-reported outcomes (PROs). The purpose of this study was to assess the effect of obesity on complication rates and PROs. METHODS This was a single-institution, retrospective study of 1093 primary TAA performed between 2001 and 2020. Minimum follow-up was 2 years. Patients were stratified by body mass index (BMI) into control (BMI = 18.5-29.9; n = 615), obesity class I (BMI = 30.0-34.9; n = 285), and obesity class II (BMI > 35.0; n = 193) groups. Patient information, intraoperative variables, postoperative complications, and PRO measures were compared between groups using univariable statistics. Multivariable Cox regression was performed to assess risk for implant failure. Mean follow-up was 5.6 years (SD: 3.1). RESULTS Compared to control and class I, class II patients had the lowest mean age (P = .001), highest mean ASA score (P < .001), and greatest proportion of female sex (P < .001) and Black/African American race (P = .005). There were no statistically significant differences in postoperative complications (infection, implant failure, or impingement) across the BMI classes (P > .05).Preoperatively, class II had lower (worse) mean scores for Foot and Ankle Outcome Score pain and ADL subscales than controls (post hoc pairwise P < .001 for both). At final follow-up, both class II and class I had lower (worse) mean Short Musculoskeletal Function Assessment (post hoc pairwise P < .001 and P = .030, respectively) and 36-Item Short Form Health Survey scores (post hoc pairwise P < .001 and P = .005, respectively) than controls. CONCLUSION At midterm follow-up, obesity was not associated with increased rates of complications after TAA. Patients with obesity reported worse musculoskeletal function and overall quality of life after TAA but there was no differential improvement in PROs across BMI classes. To our knowledge, this is the largest single-institution study to date examining the effect of obesity on outcomes after primary TAA. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
The use of fetal tissues in regenerative medicine has long been a source of both promise and controversy. Since the turn of the century, their utilization has expanded because of antiinflammatory and analgesic properties, which have been theorized to act as an avenue for treating various orthopaedic conditions. With increased recognition and use, it is essential to understand the potential risks, efficacy, and long-term effects of these materials. Given the substantial body of literature published since 2015 (the date of the most recent review of fetal tissues in foot and ankle surgery), this manuscript provides an updated reference on the topic. Specifically, we evaluate the recent literature regarding the role of fetal tissues in wound healing, hallux rigidus, total ankle arthroplasty, osteochondral defects of the talus, Achilles tendinopathy, and plantar fasciitis.

Abstract
Osteochondral lesions of the talus (OLTs) are a difficult pathologic entity to treat. They require a strong plan. Lesion size, location, chronicity, and characteristics such as displacement and the presence of subchondral cysts help dictate the appropriate treatment required to achieve a satisfactory result. In general, operative treatment is reserved for patients with displaced OLTs or for patients who have failed nonoperative treatment for 3 to 6 months. Operative treatments can be broken down into cartilage repair, replacement, and regenerative strategies. There are many promising treatment options, and research is needed to elucidate which are superior to minimize the morbidity from OLTs.

Abstract
Background Total ankle arthroplasty (TAA) provides a surgical alternative to tibiotalar arthrodesis when treating end-stage ankle arthritis. TAA preserves range of motion at the tibiotalar joint leading to improved postoperative function. Many patients who undergo TAA wish to maintain a high level of activity, including participation in low-impact sports such as golf. There are several studies in the total hip and total knee arthroplasty literature that have looked at the effect of total joint arthroplasty on golf handicap. We hypothesized that similar to hip and knee arthroplasty research, TAA is likely to result in a postoperative increase in golf handicap. Methods After obtaining institutional review board approval, we retrospectively identified 60 patients (from 140 consecutive TAAs performed between August 2016 and February 2017) who had undergone TAA, played golf pre- and postoperatively, and had at least 1 year of postoperative follow-up. The average postoperative follow-up for the cohort was 28.1 months. Variables including preoperative and postoperative golf handicaps, swing laterality, age, gender, surgical laterality, implant used, and operating surgeon were recorded. Results The average preoperative and postoperative handicaps were 19.7 and 17.9, respectively, which did not represent a statistically significant difference (P = .07). Patients who played 3 or more rounds per week had better preoperative and postoperative handicaps compared to patients who played 2 rounds or less; however, the change in their handicap following TAA and the number of rounds played per week was not affected. There was no association between the change in handicap and the follow-up period, handedness of golf shot, surgical laterality, implant used, or the operating surgeon. Conclusion Our findings showed that golf handicap was not negatively affected following TAA in this series. Level of Evidence Level IV, case series.

Abstract
Osteochondral lesions of the talus (OLTs) are lesions that occur before the physis closes and are frequently associated with acute ankle trauma. These lesions are often difficult to diagnose due to swelling and inflammation that are present after the initial injury. A growing body of literature has assessed the effects of OLTs in the adult population. However, the literature examining these lesions in the juvenile population is sparse. The purpose of this review is to provide a thorough understanding of OLTs, with a specific focus on the juvenile population. We evaluate the recent literature regarding the outcomes of various surgical treatment; modalities in the pediatric patient. While the outcomes after surgical treatment of pediatric OLTs are generally favorable, the paucity of investigation in this demographic is alarming. Further research is needed to better inform practitioners and families regarding these outcomes, as treatment plans are highly dependent on the individual patient in question.

Abstract
Background Social media platforms, like TikTok, have become popular options for the distribution of health care information. Because of the lack of scientific oversight, the quality of health care-related videos has become a focus of the current literature. However, orthopaedic surgery has lagged behind other fields in acknowledging the widespread utilization of TikTok videos for medical information consumption. This study aims to assess the quality and educational benefits of ankle sprain-related TikTok videos. Methods TikTok was queried using the hashtag "#anklesprainexercises." One hundred videos were included after applying the exclusion criteria. The number of views, likes, shares, comments, and favorites was recorded. The content was graded using DISCERN (a well-validated informational analysis tool) and ASEES (a self-designed tool for exercise evaluation). We hypothesized that information on TikTok related to ankle sprain exercises would be poor in quality. Results The total number of views of the 100 videos was 6 483 412, with a median of 5377.5 (IQR = 1074-20 275). The videos collectively received 385 847 likes, 3642 comments, 55 574 favorites, and 14 918 shares with a median of 267.5 (IQR = 41.5-1678.0), 4.0 (IQR = 0.0-23.0), 42.0 (IQR = 4.8-264.5), and 13.0 (IQR = 1.8-67.8), respectively. General users had a higher percentage of their videos graded as "very poor" (61.8%) in comparison to the number of videos uploaded by health care professionals deemed "very poor" (34.4%). Neither general user nor health care professionals had videos graded as "good" or "excellent." There were significant differences between the 2 groups for DISCERN 1, 3, and ASSES scores. Conclusion Although TikTok is a powerful tool for information distribution, the educational value of the videos related to ankle sprain injury exercises was poor. With only 2% of videos receiving a grade of "fair," and no videos reaching a score of "good" or "excellent," health care professionals should be aware of the low-quality content easily accessible on TikTok.

Abstract
BACKGROUND Social media platforms, like TikTok, have become popular options for the consumption and distribution of healthcare information. Due to the lack of scientific oversight, the consistency of healthcare-related videos has become a focus of the current literature. However, orthopaedic surgery has lagged behind other specialties in acknowledging the widespread utilization of TikTok videos for medical information. This study aims to assess the quality and educational benefits of Achilles tendinopathy-related TikTok videos. METHODS TikTok was queried using the hashtags "#achillestendonexercises", "achillestendonitisexercises", "achillestendinosisexercises", and "achillestendinopathyexercises". 100 videos (25 for each term) were included after applying the exclusion criteria. The number of views, likes, shares, comments, and favorites was recorded. The content was graded using DISCERN (a well-validated informational analysis tool) and ATEES (a self-designed tool for exercise evaluation). RESULTS The total number of views of the 100 videos was 1647,148, with a median of 7562.5 (IQR = 2,281- 19,575). The videos collectively received 73,765 likes, 1125 comments, 14,491 favorites and 6897 shares with a median of 283 (IQR= 73.8-957.8), 7 (IQR= 1.8-16.0), 61.5 (IQR= 8.8-184.3), and 18.5 (IQR= 2.0-49.8), respectively. General users uploaded slightly less (48%) when compared to healthcare professionals (52%). Healthcare professionals had more videos graded as "very poor" (43.4%) in comparison to the general users (36.2%). General users had more videos graded as "poor" (63.8%) in comparison to healthcare professionals (54.7%). However, there were no significant differences between the groups on either of the video grading scales. CONCLUSION Although TikTok is a powerful tool for information distribution, the educational value of the videos related to Achilles tendinopathy exercises was poor. With only 1% of videos receiving a grade of 'fair,' and no videos reaching a score of 'good' or 'excellent', healthcare professionals should be aware of the high viewership of low-quality content easily accessible on TikTok.

Abstract
Recent developments in robotic technologies in the field of orthopaedic surgery have largely been focused on higher volume arthroplasty procedures, with a paucity of attention paid to robotic potential for foot and ankle surgery. The aim of this paper is to summarize past and present developments foot and ankle robotics and describe outcomes associated with these interventions, with specific emphasis on the following topics: translational and preclinical utilization of robotics, deep learning and artificial intelligence modeling in foot and ankle, current applications for robotics in foot and ankle surgery, and therapeutic and orthotic-related utilizations of robotics related to the foot and ankle. Herein, we describe numerous recent robotic advancements across foot and ankle surgery, geared towards optimizing intra-operative performance, improving detection of foot and ankle pathology, understanding ankle kinematics, and rehabilitating post-surgically. Future research should work to incorporate robotics specifically into surgical procedures as other specialties within orthopaedics have done, and to further individualize machinery to patients, with the ultimate goal to improve perioperative and post-operative outcomes.

Abstract
Background The Malerba calcaneal Z-osteotomy is an operative procedure to treat the hindfoot varus component of adult cavovarus deformity. Basic science studies support the corrective ability of this osteotomy. However, there have been no published midterm clinical and radiographic results. The purpose of this article is to describe the radiographic and clinical improvement in a series of patients treated with this osteotomy. Methods A retrospective chart review identified 14 feet in 12 patients from January 2013 to August 2018 who met minimal follow-up criteria. Preoperative visual analog scale (VAS) scores, Foot Function Index (FFI) scores, and American Orthopaedic Foot & Ankle Society (AOFAS) scores were compared with postoperative scores. Preoperative Meary angle, calcaneal pitch, and hindfoot alignment were also compared with postoperative measurements. Complications and radiographic union were recorded. Results At a mean of 80 months, VAS, FFI, and AOFAS scores improved from 7.86 to 1.64, 57.78% to 18.11%, and 39.57 to 80.71, respectively (all P < .001). At a mean of 15 months, Meary angle, calcaneal pitch, and hindfoot alignment improved from 11.14 to 6.64 degrees (P < .001), 30.93 to 27.43 degrees (P = .005), and 19.83 degrees varus to 8.50 degrees varus (P < .001). There was 1 nonunion and 1 postoperative sural nerve neuralgia, but both patients ultimately did well clinically. There were no instances of postoperative tarsal tunnel syndrome. All patients stated that they would have the procedure done again. Conclusion The calcaneal Z-osteotomy is an effective method to treat adult hindfoot cavovarus deformity. All patients had good clinical outcomes with minimal complications. Level of Evidence Level IV, case series.

Abstract
CASE We report a case involving a 21-year-old woman who sustained a Grade III open pilon fracture of the left ankle during a motor vehicle accident that resulted in a 12-cm critical-sized bone defect (CSD) that was successfully treated with a three-dimensional (3D) printed titanium alloy (Ti-6Al-4V) cage, a tibiotalocalcaneal intramedullary nail, and autogenous and allograft bone. The patient's reported outcome measures were comparable with those reported for non-CSD injuries at 3-year follow-up. The authors conclude that 3D printed titanium cages offers a unique approach to traumatic limb salvage for tibial CSD. CONCLUSIONS 3D printing offers a novel solution to CSDs. To the best of our knowledge, this case report details the largest 3D printed cage, to date, used to treat tibial bone loss. This report describes a unique approach to traumatic limb salvage with favorable patient-reported outcomes and evidence of radiographic fusion at a 3-year follow up.

Abstract
The purpose of this review is to develop evidence-based practices for the use of platelet-rich plasma (PRP) to treat osseous pathologies of the lower extremity. There is moderate high-quality evidence to support the efficacy of PRP as a surgical augment to microfracture in osteochondral lesions of the talus (OLT). The literature supports a conceivable positive impact on bony union and osseous healing. There is insufficient evidence to support PRP injections in the conservative management of OLT or symptomatic ankle osteoarthritis. PRP may serve as a viable treatment method in the surgical augmentation of microfracture surgery in OLT and has promise for increasing bony union following surgical operations. Further high-quality, comparative studies with longer clinical follow-up are required.

Abstract
Tarsal coalitions are abnormal fibrous or bony connections between the tarsal bones of the foot. While not always symptomatic, coalitions can cause pain, alterations in forefoot and hindfoot morphology, and alterations in foot and ankle biomechanics. Previous research has described the association of tarsal coalitions with fractures of the lower extremity. Multiple reports of acute fracture in the presence of tarsal coalition have been presented, as have reports of stress fractures of the foot and ankle with concomitant coalition, insidious in onset and thought to be related to aberrancies in foot and ankle biomechanics. The purpose of this review is to discuss the biomechanics seen in tarsal coalitions and to describe reports of fracture occurring concomitantly with tarsal coalitions. We will discuss diagnostic options and treatment approaches in the setting of fracture with preexisting tarsal coalition.

Abstract
Total ankle arthroplasty (TAA) is an increasingly utilized treatment for ankle arthritis, and opioids are commonly used as part of perioperative pain control. However, many states have enacted opioid-limiting legislation to reduce perioperative opioid prescribing. The aim of this study was to evaluate the impact of time and state legislation on perioperative opioid prescribing in TAA. This study is a retrospective, observational review of 90-day perioperative opioid prescribing in 1,829 patients undergoing TAA throughout the United States using a large insurance database. Initial and cumulative volumes and rates of opioid prescription filling were recorded along with baseline patient and operative characteristics. Dates of state legislation enactment were also recorded. Student t-tests, analysis of variance, and multivariable linear and logistic regression were utilized to analyze the impact of time and state legislation on opioid prescription filling. In the 90-day perioperative time period, initial and cumulative opioid prescription filling in oxycodone 5-mg equivalents has decreased significantly from 2010 (63.8 initial and 163.3 cumulative) to 2019 (41.1 initial and 67.2 cumulative). States with opioid-limiting legislation saw larger and more significant reductions in initial and cumulative opioid prescription filling preact to postact (63.3-50.6 with legislation vs 61.4-51.9 without legislation initial and 146.4-93.3 with legislation vs 125.1-108.6 without legislation cumulative). This study demonstrates that foot and ankle surgeons in states with opioid-limiting legislation have responded by significantly reducing 90-day perioperative opioid prescribing in TAA. These results encourage states without legislation to enact opioid-specific laws to reduce opioid prescribing.

Abstract
INTRODUCTION The treatment of pathologic changes to the talus and surrounding joints presents a unique challenge to the foot and ankle surgeon. The purpose of this systematic review is to summarize the literature for unconstrained (no surrounding fusion or replacement) total talus replacement (TTR) and evaluate whether it leads to improved clinical and radiographic outcomes and appropriate safety metrics. METHODS Concepts of talus and arthroplasty were searched in MEDLINE, Embase, CINAHL Complete, and Scopus from 2005 to 2021. Inclusion Criteria were 1) previous trauma to the talus, 2) post-traumatic or degenerative arthritis to the tibiotalar joint, 3) avascular necrosis of talus, 4) multiple failed prior interventions, and 5) inflammatory arthropathy to tibiotalar joint. Manuscripts in non-English languages or those with concomitant total ankle arthroplasty or revision arthroplasty were excluded. RESULTS Twenty-two studies of 191 patients (196 ankles) were included. Nineteen studies utilized third generation implants, two studies used first generation (n = 9) and one study used second generation implants (n = 14) made largely of ceramic (n = 84), cobalt chrome (n = 49), or titanium (n = 24). Patient-reported outcome measures were favorable in all described categories (Table 4) with ten studies reporting an average postoperative change of + 2.92° of dorsiflexion and - 2.05° plantarflexion at final follow-up. The most common adverse outcome was adjacent joint arthritis with five studies reporting some degree of postoperative, degenerative changes in the surrounding joints (n = 52). CONCLUSION TTR is an alternative to joint sacrificing procedures to maintain range of motion through the tibiotalar joint and allow for maintenance of normal foot and ankle biomechanics. Despite promising early- and mid-term outcomes, future, prospective, randomized research should be conducted to better assess survivorship and complication rates with direct comparison of TTR to existing forms of salvage options for advanced talar pathology.

Abstract
BACKGROUND End-stage ankle arthritis is a debilitating condition often necessitating total ankle replacement (TAR). Tendo-Achilles lengthening (TAL) and gastrocnemius recession (GR) are commonly performed with TAR to improve ankle dorsiflexion (DF). No studies to date have radiographically analyzed tibiopedal motion to guide surgical management. The purpose of this study is to determine the effect of a TAL or GR during TAR on radiographic tibiopedal range of motion (ROM). METHODS A retrospective review of a prospectively maintained database was conducted followed by a propensity score-matched analysis of 110 patients who underwent TAL (n = 26), GR (n = 29), or no lengthening procedure (n = 55) with TAR. Minimum of 1-year ROM radiographic follow-up was required. Exclusion criteria included (1) calcaneal osteotomies, (2) simultaneous or previous hindfoot or midfoot arthrodesis, (3) prior ankle arthrodesis, or (4) revision TAR. Demographic data were extracted from the TAR database. Radiographic assessment included tibiopedal dorsiflexion (DF) and plantarflexion (PF). RESULTS DF improved by 2.8 degrees (P = .0286) and by 6.0 degrees (P < .0001) in the TAL and GR cohorts, respectively, with no difference in the control group (+0.7 degrees, P = .3764). PF was decreased by 4.5 degrees (P = .0152) and by 7.2 degrees (P = .0002) in the TAL and GR cohorts, respectively, with no difference in the control group (-0.2 degrees, P = .8546). Minimal differences were observed for total arc of motion for all 3 groups (control 0.5 degrees, GR -1.2 degrees, TAL -1.7 degrees), all of which were nonsignificant (all P > .05). There was no between-group difference in the change in overall arc of motion between the groups (P = .3599). GR resulted in a greater increase in DF (6.0 vs 2.8 degrees; P = .1074), with a reciprocal greater decrease in PF (7.2 vs 4.5 degrees; P = .2416) compared with the TAL cohort. CONCLUSION Both TAL and GR increased postoperative DF; however, this was accompanied by a reciprocal loss in PF. Minimal differences were observed for total arc of motion. Patients should be counseled that concomitant procedures performed to increase DF will do so at the expense of PF. LEVEL OF EVIDENCE Level III, retrospective review of prospectively collected data.

Abstract
➢ The preparation methodology for platelet-rich plasma (PRP) may have important clinical implications with varying effectiveness with leukocyte, platelet, and growth factor concentrations. ➢ There is high-quality evidence to support the superiority of PRP over corticosteroids in the case of chronic plantar fasciitis. ➢ There is moderate-quality to high-quality evidence for PRP's ability to increase tendon thickness with no capacity to decrease pain, increase function, or augment percutaneous tenotomy in Achilles tendinopathy. ➢ There is insufficient evidence to support PRP injections in the definitive treatment of Achilles tendon rupture. However, PRP may contribute to postoperative recovery after tendon rupture repair, but this requires further research. ➢ The biochemical theory supporting the clinical use of PRP must be reinforced with high-level evidence research. Based on the current literature, PRP may serve as a viable treatment method in chronic plantar fasciitis. Further high-quality, comparative studies with longer clinical follow-up are required to support recommendations for use of PRP in the treatment of Achilles tendon pathology.

Abstract
Category: Ankle; Ankle Arthritis Introduction/Purpose: Even as its popularity increases, there remain many unanswered questions regarding total ankle arthroplasty. One debate considers how best to restore proper rotation of the talar component relative to native, non- osteoarthritic anatomy. At present, two common schools of thought are to parallel the talar component rotation with the medial gutter line or to choose a line that bisects the gutters. These axis' are then considered with respect to a chosen foot axis, often defined by the second metatarsal or second toe clinically. The present study sought to define the foot center axis relative to the ankle on weight-bearing CT in patients without ankle osteoarthritis to inform talar component positioning in total ankle arthroplasty. Methods: Following IRB approval, charts were reviewed to identify patients without ankle osteoarthritis, trauma or other deformity who received a weightbearing CT scan. A pilot group of n=34 patients were included for a total of n=50 limbs. Average age was 50.3 +/- 7 and there were = 54% female patients. All measurements were made on MPR (multiplanar reformation) axial reconstructions. Cobb angle measurements between the anatomic foot center, the second, the fourth metatarsal and the gutter bisector or medial gutter line were recorded. Statistical analysis was performed by IBM SPSS Statistics for Windows, Version 27.0. Armonk, NY. Results: The mean gutter bisector angle was 5.7 deg +/- 2.0. The mean cobb angle between the anatomic foot center and the medial gutter line was 6.1 deg +/- 4.4 and between the anatomic foot center and gutter bisector was 6.3 deg +/- 4.8, there was no statistical difference between measurements (p=0.62, Table 1). The mean cobb angle between the second metatarsal and the gutter bisector was 9.9 deg +/- 6.8, whereas the mean cobb angle between the fourth metatarsal and the gutter bisector was 7.5 deg +/- 5.2, which was not statistically significant (p=0.053). There was no statistical difference between mean cobb angle measurements between the anatomic foot center and the gutter bisector and the fourth metatarsal and the gutter bisector (p=0.243), but there was statistical difference between mean cobb angle measurements of the second metatarsal and the gutter bisector and the anatomic foot center and the gutter bisector (p=0.003). Conclusion: The axial alignment of the foot center axis relative to the ankle in patients without deformity or osteoarthritis is most collinear with the medial gutter line. In general, the axial alignment of the ankle joint relative to the foot in patients without osteoarthritis tends towards <10 degrees of difference on weight-bearing CT, regardless of method chosen. Due to both the consistency of measure and reproducibility of measure on pre-operative weight-bearing CT, the anatomic foot center may be a useful guide for establishing intra-operative foot orientation when performing total ankle arthroplasty.
