Category: Ankle; Other Introduction/Purpose: Ankle sprains are one of the most common musculoskeletal injuries, and most will respond to nonoperative management. However, approximately 20% of patients will develop chronic ankle instability [CAI]. Surgical treatment of CAI is indicated when conservative treatment is not effective after three months with the Broström-Gould reconstruction being the gold standard. The healthcare utilization and costs of prolonged conservative treatment of operative musculoskeletal pathologies is understudied, so we aim to evaluate the patterns of healthcare utilization and estimated cost of care among patients who underwent Brostrom repair, contrasting those who sought surgical intervention earlier versus at later stages. This study could help demonstrate the economic burden placed on patients and the healthcare system with unnecessary prolonged nonoperative management of operative foot and ankle pathologies. Methods: MarketScan was queried for patients undergoing Brostrom Repair in both the inpatient and outpatient setting between January 2009 through December 2022 along with their corresponding nonsurgical encounters. ICD9/10 codes were used to identify patients with ankle instability as their primary diagnosis. Patients were then categorized into groups depending on the number of days between when they first presented for ankle instability and when they had a Brostrom Repair (within 1 month, 2-3 months, 3-6 months, 6 months-1 year, 1-2 years, and 2+ years). The number of patient encounters (which included physical therapy [PT], primary care visits, orthopedic visits, imaging, and corticosteroid injections ) was counted before and after surgery. Patients’ average number of encounters was calculated for each modality of visits. A two-sample t-test was used to compare the average usage before and after surgery (α = 0.05). Results: There was a total of 104,608 patient encounters (29.9% male, 70.1% female) with an average age of 35.9 +/- 14.9. Comparing average healthcare utilization before and after surgery, there was a significant decrease in patients undergoing surgery within 1 month. As the patient waits longer for surgery (1 month+), there is an upward trend of post-operative healthcare utilization. For patients that delayed surgery for 1 year or more, there was a significant increase in post-operative PCP visits, imaging, and consult visits. Cohorts that did not delay surgery for more than a year had a significant decrease post-operative imaging and PCP visits. For patients that delayed surgery for 1-3 months, patients had a significant decrease in almost all modalities (PCP visits, imaging, injections, and consults) post-operatively. Conclusion: This study evaluates the perioperative healthcare utilization of patients undergoing a Brostrom repair. Given that the average healthcare utilization of nonsurgical visits is significantly lower for the group who received surgery within 3 months of presenting with a diagnosis of ankle instability, there is merit for both the patient and the healthcare system for electing for an earlier surgery. This research opens the possibility of modeling the optimization of nonsurgical management to reduce overall healthcare utilization and thus costs.

Category: Midfoot/Forefoot; Ankle Introduction/Purpose: Venous thromboembolism (VTE) after foot and ankle surgery is a significant concern for patients and surgeons. The absence of guidelines for thromboprophylaxis in elective procedures underscores the importance of understanding risk factors. This study aimed to identify key risk factors of VTE in patients who underwent elective foot and ankle surgery, analyzing the rates based on the anatomical location of the surgery and the post-operative period. Methods: Data was collected from IBM MarketScan Database (2009-2019) for patients >18y without prior VTE who underwent elective foot/ankle surgery. Patients were divided into three groups based on region of surgery (forefoot, mid/hindfoot, lower leg/ankle), and VTE incidence was recorded 30- and 90-days post-surgery. Risk factors for VTE were identified through multivariate logistical regression analysis. Results: Among the 301,256 patients who underwent elective foot and ankle surgeries, the overall incidence of VTE within 90 days was 0.95%. The findings revealed that 31.8% of VTE incidents occurred within the first two weeks after surgery, and 29.2% still occurred after 6 weeks. An analysis of the anatomical region of surgery demonstrated that the lowest rate of VTE was amongst patients undergoing forefoot surgery (0.70%). There was a higher incidence and risk for VTE in patients undergoing midfoot/hindfoot surgery (1.22%, OR = 1.75) and lower leg/ankle surgery (1.76%, OR= 2.53). Additional risk factors for VTE included thrombophilia (OR = 5.06), male sex (OR = 1.43), increasing age (OR > 1.25), and a high Charlson Comorbidity Index (OR < 0.82 for scores < 5). Conclusion: This study identifies the incidence and timing for VTE after elective foot and ankle surgery. Furthermore, this study defines the risk factors associated with increased odds of VTE after elective foot and ankle surgeries. These findings are helpful in educating patients about a continued risk for VTE throughout the 90-day postoperative period. These results can also be utilized to stratify patients who need thromboprophylaxis based on the individual risk level.

Category: Ankle; Sports; Trauma Introduction/Purpose: Traditionally, open surgical repair has provided improved functional outcomes, reduced re-rupture rates, and quicker recovery and return to activities at the expense of increased wound complications of infection and skin necrosis compared to nonoperative management. Ma and Griffith in 1977 introduced the percutaneous approach, and over the following decades, multiple improved techniques, and modifications thereof, have been described with comparable outcomes to the open repair. The current study aims to provide updated level I evidence comparing the open and minimally invasive (MIS) through a comprehensive search of literature published in English, Spanish, Portuguese, and German while avoiding limitations of previous studies such as heterogeneous study designs and a small number of included studies. Methods: Following the PRISMA guidelines, two independent team members searched several databases to identify randomized controlled trials (RCTs) comparing open and MIS Achilles tendon repairs. The primary outcomes were (1) Sural nerve injury, (2) Skin complications, (3) Infection (deep/superficial), whereas the secondary outcomes were (1) AOFAS/ATRS score, (2) surgical time, (3) re-rupture (4) adhesions (5) ankle range of motion. Population: Achilles tendon rupture Intervention: MIS repair Control: Open repair Outcomes: Primary: (1) Sural nerve injury, (2) Skin complications, (3) Infection (deep/superficial) Secondary: (1) AOFAS/ATRS score, (2) surgical time, (3) re-rupture, (4) adhesions, (5) ankle range of motion (6) other complications. Results: Ten RCTs qualified for the meta-analysis with a total of 522 patients. 260(49.8%) patients had open repair while 262(50.2%) had MIS repair. The mean total complication rate was 15.5% (0-36.4%) in open repair vs. 10.4% (0-45.5%) in MIS repair, with non-significant statistical difference (RR= 1.50,CI=0.87-2.57,p= 0.14;I2=40%). The mean re-rupture rate was 2.5% (0-6.8%) in open repair vs. 1.53% (0-4.6%) with MIS repair, with non-significant statistical difference (RR=1.56,CI=0.42-5.70,p= 0.50;I2=0%). No cases of sural nerve injury were reported in the open repair group. The mean sural nerve injury was 3.4%(0-7.3%) in the MIS group, that was statistically significant (RR= 0.16,CI=0.03-0.46,p=0.02;I2=0%). The mean deep infection rate in the open group was 1.4% (0-5%) while no deep infection was reported in MIS, with no statistically significant difference (RR= 3.24,CI=0.48-20.54,p= 0.23;I2=0%). The mean superficial infection rate was 6.04% (0-18.2%) and 0.40% (0-4.5%) for open and MIS repairs, respectively, with statistically significant difference (RR= 5.70,CI=1.80-18.02,p< 0.001;I2=0%). Conclusion: Open Achilles tendon repair is associated with longer surgical time, higher risk of superficial infection, and ankle stiffness, while MIS repair is associated with a greater risk of temporary sural nerve palsy. Re-rupture rate and functional outcomes are mostly equivalent. We found MIS to be a safe and reliable technique. However, high-quality standardized RCTs are still needed before recommending MIS as the gold standard for the management of Achilles tendon rupture.

Category: Other Introduction/Purpose: Non-union of foot and ankle arthrodesis sites has been associated with revision surgery, morbidity and increased healthcare costs, so many surgeons elect to augment the fusion site with autologous bone grafts to improve union. While iliac crest autografts are considered the historical gold standard, other donor sites distal in the lower extremity such as calcaneus, proximal and distal tibia have been successfully used in foot and ankle surgery. This study aims to report on the safety and donor site morbidity of distal lower extremity (calcaneal, proximal and distal tibial) bone autografts. We summarized the findings in a comprehensive infographic illustration. We are unaware of any similar meta-analyses to date. Methods: Following the PRISMA guidelines, 2 independent investigators searched several databases in December 2020 using the following keywords and their synonyms: ('Bone graft', 'donor site morbidity', 'calcaneal graft', 'Proximal tibia graft', and 'distal tibia graft'). Besides, the reference lists from previous review articles were searched manually for eligible studies. The primary outcomes of interest were (1) Chronic pain, (2) Fracture and (3) infection whereas the secondary outcomes were (1) neurological complications, (2) sensory disturbance and hypertrophic scars, (3) other complications such as shoe-wear difficulties and gait disturbance. Inclusion criteria were: studies on complications and adverse events of lower extremity bone autografts (calcaneal, proximal tibial, and distal tibial bone autografts) reporting at least one desired outcome. Studies not reporting any of the outcomes of interest or if the full text is not available in English were excluded. Studies reporting on bone marrow aspirate or autografts for non-orthopedic indications were also excluded. Results: After removal of duplicates, 5981 studies were identified. After screening, 85 studies remained for full-text assessment, and 15 studies qualified for the meta-analysis with a total of 2296 bone grafts.1557(67.8%) were calcaneal grafts, 625 (27.2%) were proximal tibial grafts, and 114 (5%) were distal tibial grafts. The mean age of all patients was 52.43+-16 [CI=51.77-53.08] years. The mean follow-up duration was 1.86+-1.70[CI=1.79-1.93] years. The primary surgery was reported for 2129 grafts(92.7%).Out of those, foot and ankle procedure represented 97.4% of the procedures. In calcaneal bone grafts, there were 28 cases of chronic pain [1.97%,CI:1.10-2.50%, I2=66%], 5 fractures [0.32%,CI:0.10-0.60%, I2=0%], 20 sural neuritis [1.28%,CI:0.70-1.80%, I2=0%), and no wound infections. In proximal tibial grafts there were 13 cases of chronic pain [2.08%,CI:1.01-3.2%, I2=34.5%], 1 fracture [0.16%,CI:0.10-0.50%, I2= 0%], and 3 superficial wound infections [0.48%,CI:0.10-1.01, I2=0%]. In the distal tibial grafts there were no cases of chronic pain or wound infections, 1 fracture [0.90%,CI:0.80-2.6%,I2=0%], and 5 saphenous neuritis [4.5%,CI: 0.70- 8.40%,I2=65%]. Conclusion: Calcaneal, distal tibial, and proximal tibial bone autografts are safe with a low rate of overall and major complications. We report an overall complication rate of 6.8%, which is less than half of that previously reported for iliac crest grafts. The authors recommend using distal lower extremity grafts for foot and ankle primary surgeries instead of iliac crest grafts when indicated. Clinical trials with large sample sizes are required.

Category: Ankle; Arthroscopy; Sports Introduction/Purpose: Ankle sprains are the most common ankle injury accounting for up to 85% of all ankle injuries, and nearly 20% of acute ankle sprains progress to chronic lateral ankle instability that requires surgical intervention. In recent years, there has been a growing interest in arthroscopic Broström techniques as an alternative to open surgery. In the past two years alone, four comparative studies have been published. Recent case series and cohort studies showed reliable improvement in clinical and radiographic outcomes with arthroscopic surgeryAIM. The current study aims at providing the foot and ankle surgery community with the most updated evidence comparing outcomes of open to arthroscopic Broström procedure for chronic lateral ankle instability. Methods: This article was performed following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Two independent authors searched several databases for relevant comparative studies in English literature were identified between database inceptions to May 2020. The primary outcomes were (1) Functional scores (KAFS, AOFAS) and (2) Pain score on VAS, whereas the secondary outcomes were differences in (1) anterior drawer and talar tilt, (2) surgical time and complications rate, (3) time to return to sports and weight-bearing. Population: Chronic lateral ankle instability (LAI)Intervention: Arthroscopic Broström procedure Control: Open Broström procedure Outcomes: Primary: Functional scores, pain Secondary: Anterior drawer and talar tilt, complications, time to return to sport and weight-bearing Results: A total of 408 patients in eight studies met the inclusion criteria were subjected to analysis. 193 (47.3%) patients underwent open surgery, while 215 (52.7%) patients underwent arthroscopic surgery. The one year-AOFAS was 80.05 vs. 88.6 in open and arthroscopic surgery, respectively (MD= -11.96, CI= -21.26, -2.76, I2= 82%, p= 0.01). The mean one year VAS was 2.05 and 1.45 in open and arthroscopic repair, respectively (MD= 0.31, CI= 0.09 to 0.54, I2=0%, p

Background: The COVID-19 pandemic created a difficult environment to provide musculoskeletal care to patients with foot and ankle pathology given the limitations placed on in-office visits. Telemedicine offered a unique avenue to reach these patients; however, the efficacy of telemedicine visits in patients with foot and ankle pathology is not well studied. We propose a telemedicine protocol that has allowed us to effectively see and treat patients with foot and ankle pathology. Methods: A 12-step standardized telemedicine protocol was created within the Foot and Ankle division that was used for seeing patients through telemedicine. Also included in this is previsit preparation and follow-up recommendations. Press Ganey surveys were retrospectively reviewed to understand patient experience with telemedicine. Results: 85.2% of patients surveyed responded with scores indicating excellent care. When comparing patients who were seen in-office and through telemedicine, 89.2% and 83.4% responded with scores indicating excellent care, respectively ( P = .37). Conclusion: Telemedicine offers an effective and convenient way to provide excellent musculoskeletal care to patients affected with foot and ankle pathology. This is the first study that evaluated a comprehensive protocol for telemedicine encounters and can be used to implement telemedicine by others using this approach. Level of Evidence: Level V, expert opinion.

Category: Other Introduction/Purpose: The current COVID-19 pandemic has created a unique problem for orthopaedic surgeons by mandating ‘social distancing’ and limiting patient-provider interactions. Centers have reacted to this by implementing Telemedicine as a way to still provide care for patients. We have developed a Telemedicine protocol we believe allows for enough information to be gathered to provide an accurate diagnosis and with high patient satisfaction. Methods: A 12-step standardized protocol was created to be used during foot and ankle Telemedicine visits. This was coupled with pre-visit preparation by the office staff with the patient as well as recommending appropriate follow-up either in person or again via Telemedicine. After implementation of this system in April 2020, we retrospectively reviewed Press-Ganey data collected for provider rating (scale 0-10) with Telemedicine visits and traditional office visits through June 2020. Scores of 9 and 10 out of 10 were grouped together to represent an excellent experience, and all other responses were grouped together as a less than excellent experience. Fischer’s exact test was used to compare samples. Results: A total of 183 patients were surveyed during this time period, 127 from telemedicine visits and 56 from in-office visits. 106/127 (83.4%) patients surveyed after Telehealth visits and 50/56 (89.2%) after in-person visits rated their visit as a 9 or 10 (p=0.37). Conclusion: The COVID-19 pandemic has changed the way that orthopaedic surgeons have needed to deliver care to their patients. Though the transition has had its difficulties, it would be a failure in progress to not recognize and adopt the advances that have been made during this time. Though the adaption of Telemedicine was made out of necessity at our institution, the lessons learned during this trying time has enabled us to provide excellent orthopaedic care through telemedicine that can continue once restrictions have been lifted.

Category: Hindfoot; Sports; Trauma Introduction/Purpose: Rupture of the Achilles tendon is a common injury that requires a lengthy duration of recovery and rehabilitation. Patients of various levels of physical activity, ranging from professional high-impact sports to low-impact recreational activities, can be affected by this injury. Often, one of the most important outcomes from the patient’s perspective is the ability to return to the same pre-injury level of sporting activity after recovery. The objective of the current study is to examine the relationship between global ankle strength and the ability to return to previous level of play following surgical repair of an Achilles tendon tear. Methods: Patients aged 18-50 years old at a minimum 1-year post-op from surgical repair of an isolated Achilles tendon rupture were recruited to return for a study visit. Patients reported both pre-injury and current activity level using the 10-point Tegner Activity Level Scale. Isokinetic strength testing was performed and the Isokinetic Strength Score (ISS) was calculated using maximal effort dorsiflexion and plantarflexion strength at 30o/s, 90o/s, and 240o/s comparing the operative and uninvolved extremity. The primary outcome was the patients’ ability to return to same level of play or within 1 Tegner activity level. Logitistic regression analysis was used to determine the relationship between ISS and return to play. Subgroup analysis was performed on patients participating in high level athletic activity (pre-injury Tegner >= 7) an those participating in only recreational or low level activity (pre-injury Tegner = 7), for every 16 point increase in ISS, the odds ratio for return to same level of play was 8.3 (p=0.055) and the OR for return to within 1 Tegner level of play was 6.3 (p=0.043). There was no association between ISS and return to previous activity in the 16 patients with lower pre-injury levels of activity. Conclusion: Improved ankle strength was associated with return to previous level of activity only in patients who participate in high level athletic activity. These results suggest that patients with more strenuous athletic activity prior to injury are more dependent on recovery of ankle strength in the post-operative time period in order to return to their previous high level of play. In contrast, regaining strength may be less important for returning to normal activities for less active patients.

Category: Other; Ankle; Hindfoot; Midfoot/Forefoot Introduction/Purpose: A lack of access to care is predictably associated with negative outcomes in foot and ankle surgery. Despite recent advances in telecommunication technologies, the field of orthopaedics has been slow to adopt these resources in offsetting barriers to care. The COVID-19 pandemic has forced departments to change their clinical approach, lending unprecedented opportunity to better understand how telehealth may bridge this care gap in foot and ankle practices. The purpose of this study was to assess patient-reported outcomes of telemedicine encounters, including comfort and patient satisfaction. Our hypothesis was that patients would be significantly less satisfied with telemedicine when compared to in-office appointments for all non-emergent visit types. Methods: Retrospective analysis of patients seen via telemedicine between April 13, 2020, to June 19, 2020, by one surgeon in the Emory Orthopedics Foot and Ankle department was conducted. Patients were contacted by one of the study authors via telephone to complete a questionnaire; satisfaction and other visit characteristics were assessed with a modified Likert scale from 1 to 5. Patients were designated as either ‘New’ or ‘Established’ based on whether or not they had completed an in-office clinic visit within the last year. Anatomy and pathology of disorder were determined by chief complaint and billing code. Patient demographics were recorded, and data were analyzed using paired and independent t-tests for parametric continuous data, Fisher’s exact and chi-square tests for non-continuous data. Results: 338 eligible patients were contacted via telephone, with 216 (63.9%) completing the telemedicine questionnaire. The patient cohort had an average age of 50.6 (19-84) years old and was 73.6% female (n=159). Overall mean satisfaction for telemedicine visits (4.69) was significantly lower than in-office visits (4.86) (p
