Mechanism of Injury for Traumatic Mid-Foot Lisfranc Injuries: Impact of the COVID-19 Pandemic.

Background During the COVID-19 pandemic, Americans transitioned away from their normal routines, drove in motor vehicles less, and reduced their physical activity, ultimately influencing the incidence and nature of orthopedic injuries that were operatively managed. The purpose of this study was to evaluate the effect of the COVID-19 pandemic lockdown and subsequent deconditioning on the mechanism of injury and severity of Lisfranc injury. Methods This retrospective study included patients with a traumatic Lisfranc injury who were surgically treated by a foot and ankle fellowship-trained orthopedic surgeon between 2015 and 2021. Electronic health records were queried for patient demographics, mechanism of injury, physical exam findings, and pain scores. Preoperative radiographs were reviewed to grade Lisfranc injuries using the previously described Nunley-Vertullo classification system. Descriptive and univariate statistics were performed to compare 15 patients in the pre-COVID-19 cohort and 15 patients in the post-COVID-19 cohort. Results In the pre-COVID-19 cohort, 80% (n=12/15) of the patients were female, the mean age was 46±15 years, the mean BMI was 29.7±7 kg/m2, and the mean follow-up period was 18.1±12 months. In the post-COVID-19 cohort, 53% (n=8/15) of the patients were female, the mean age was 48.5±17 years, the mean BMI was 31.4±7 kg/m2, and the mean follow-up period was 9.5±4 months. Significantly higher proportions of plantar ecchymosis (n=8/15, 53%), neuropathic pain (n=7/15, 47%), and swelling (n=12/15, 80%) were present in the post-COVID-19 cohort. A low-energy mechanism of injury was sustained by 73% (n=11/15) of the pre-COVID-19 cohort and 80% (n=12/15) of the post-COVID-19 cohort. Lisfranc injuries for the pre-COVID-19 cohort and the post-COVID-19 cohort demonstrated the following classifications: Grade 1 (33%, n=5/15 vs. 40%, n=6/15), Grade 2 (60%, n=9/15 vs. 53%, n=8/15), and Grade 3 (7%, n=1/15 vs. 7%, n=1/15). Conclusion Although a higher proportion of plantar ecchymosis, neuropathic pain, and swelling was observed, there was no association between a low mechanism of injury and a higher grade of Lisfranc injury following the COVID-19 pandemic.

Polyvinyl Alcohol Hydrogel Hemiarthroplasty of First Metatarsophalangeal Joint Hallux Rigidus.

Background Hallux rigidus (HR) is the most common arthritic condition of the foot. Although first metatarsophalangeal joint (MTPJ) arthrodesis has been the historical gold-standard treatment, polyvinyl alcohol (PVA) hydrogel implants have gained popularity as a joint-sparing technique. However, recent studies have shown variable failure rates of PVA hydrogel implants. The purpose of this study was to report the five-year experience with PVA hydrogel implants performed by a single surgeon. Methodology Health records were queried from August 2016 to 2021 for patients who underwent primary PVA hydrogel implant hemiarthroplasty for symptomatic late-stage HR. Patient demographics and postoperative outcomes variables were evaluated. Kaplan-Meier analysis was used to evaluate implant survival. A total of 146 PVA hydrogel implant procedures were performed with a minimum six-month follow-up. Results The majority of patients were female (n = 103, 70.5%), with a mean age of 58.1 (±10.1) years, body mass index of 27.3 (±5.2) kg/m2, and American Society of Anesthesiologists score <3 (n = 131, 89.7%). The majority had stage II or III disease (n = 115, 78.8%). Patients experienced significant improvement in visual analog scale score (p < 0.0001) and hallux dorsiflexion (p = 0.0005). There were 22 (15.1%) complications, including implant subsidence (n = 15, 10.3%), deep infection (n = 6, 4.1%), and hypertrophic ossification (n = 1, 0.7%). Revision surgeries were required in 12.3% (n = 18) of patients at an average of 9.4 (±9.2) months postoperatively. This included nine (6.2%) revision PVA hydrogel implant procedures and nine (6.2%) first MTJP arthrodesis. The one- and two-year survival rates for MTPJ arthrodesis (n = 9) were 95.9% and 86.3%, respectively. Conclusions In the largest single-surgeon series reported, first MTPJ hemiarthroplasty with a PVA hydrogel implant significantly improved pain and hallux dorsiflexion at an average of 14.5 months postoperatively. There was a high two-year survivorship of 86.3% until failure which required first MTPJ arthrodesis. Future studies should be performed to refine the indications for PVA hydrogel implants and identify risk factors.

Effect of Cigarette Smoking on Postoperative Outcomes After Arthroscopic Bone Marrow Stimulation for Osteochondral Lesions of the Talus.

BACKGROUND: Bone marrow stimulation (BMS) is presently considered first-line surgical treatment for osteochondral lesions of the talus (OLTs); however, some patients still experience pain or dysfunction after surgery, and the reasons for success or failure remain somewhat unclear. This study aimed to investigate the effect of smoking on postoperative outcomes after arthroscopic BMS for OLTs. METHODS: Consecutive patients with OLTs who underwent BMS between January 2017 and January 2020 were included. Smokers were defined as patients who actively consumed cigarettes before surgery and postoperatively, whereas nonsmokers were patients who never smoked. Visual analog scale (VAS), American Orthopaedic Foot & Ankle Society ankle hindfoot score (AOFAS), Karlsson-Peterson, and Tegner scores were assessed preoperatively and at follow-up. Additionally, a general linear model (GLM) was performed, followed by the interaction analysis to explore the potential influence of smoking. RESULTS: The study enrolled 104 patients with a mean follow-up of 30.91 ± 7.03 months, including 28 smokers and 76 nonsmokers. There were no significant differences in patient age (35.2 ± 10.0 years vs 37.6 ± 9.7 years, P = .282) or OLT area (63.7 ± 38.7 mm2 vs 52.8 ± 37.0 mm2, P = .782). Both univariate analysis and GLM revealed that smoking was associated with worse postoperative pain levels, Karlsson-Peterson, and AOFAS scores (P < .05). The interaction analysis showed a significant interaction between smoking and OLT area for postoperative Karlsson-Peterson scores (general ankle function) (P = .031). Simple main effects analysis revealed that the negative effect of smoking on Tegner score significantly increased among patients >32 years old or with OLT area>50 mm2 (P < .05). CONCLUSION: Smoking was associated with worse clinical outcomes following BMS of OLTs. As the size of OLTs increased, the difference in general ankle function between smokers and nonsmokers also increased. Furthermore, smokers who were older than 32 years or had larger OLTs were less likely to resume participation in high-level activities.

Foot and Ankle Patient Education Materials and Artificial Intelligence Chatbots: A Comparative Analysis.

BACKGROUND: The purpose of this study was to perform a comparative analysis of foot and ankle patient education material generated by the AI chatbots, as they compare to the American Orthopaedic Foot and Ankle Society (AOFAS)-recommended patient education website, FootCareMD.org. METHODS: ChatGPT, Google Bard, and Bing AI were used to generate patient educational materials on 10 of the most common foot and ankle conditions. The content from these AI language model platforms was analyzed and compared with that in FootCareMD.org for accuracy of included information. Accuracy was determined for each of the 10 conditions on a basis of included information regarding background, symptoms, causes, diagnosis, treatments, surgical options, recovery procedures, and risks or preventions. RESULTS: When compared to the reference standard of the AOFAS website FootCareMD.org, the AI language model platforms consistently scored below 60% in accuracy rates in all categories of the articles analyzed. ChatGPT was found to contain an average of 46.2% of key content across all included conditions when compared to FootCareMD.org. Comparatively, Google Bard and Bing AI contained 36.5% and 28.0% of information included on FootCareMD.org, respectively (P < .005). CONCLUSION: Patient education regarding common foot and ankle conditions generated by AI language models provides limited content accuracy across all 3 AI chatbot platforms. LEVEL OF EVIDENCE: Level IV.

Early Outcomes of Third-Generation Minimally Invasive Chevron-Akin (MICA) Osteotomy for Symptomatic Hallux Valgus Deformity.

Hallux valgus is a common progressive forefoot deformity. Although open techniques have shown good outcomes, no technique has been shown to be superior to other techniques. The current third generation of minimally invasive Chevron-Akin (MICA) technique features a percutaneous procedure with a stable internal fixation. The technique used in this study resulted in stable internal fixation; however, 1 screw was used in intramedullary fashion in the majority of cases. The purpose of this study is to review the early outcomes of MICA. Electronic Health Records (EHR) were queried for patients who underwent MICA to treat hallux valgus (HV) deformity, by a single surgeon. The primary clinical outcomes assessed were visual analog pain score (VAS), rate of revision surgery, and recurrence. Radiographic outcomes were assessed including pre and postoperative hallux valgus angle (HVA), intermetatarsal angle (IMA), and bony foot width. The secondary outcomes included postoperative complications. A total of 91 feet underwent MICA to correct symptomatic HV deformity. The mean age of this cohort was 53.63 ± 15.42 years, mean body mass index (BMI) of 26.81 ± 6.21 kg/m2, mean follow-up of 6.33 ± 6.39 months and 87 feet belonged to female patients. Patients showed significant improvement in VAS and radiographic outcomes at final follow-up, with a mean improvement of 10.70° ± 6.42°, 2.39° ± 3.55°, and 5.30 mm ± 4.23 mm for the HVA, IMA, and bony foot width, respectively. Two patients (2.2%) required revision surgery for nonunion and removal of symptomatic hardware. One patient had a second metatarsal fracture treated nonoperatively. No feet had recurrence, hardware loosening, infection, or scar hypersensitivity. The current study reported on early outcomes for MICA. This technique appears to be effective and safe with no failure of fixation in our patients. We showed in our short-term follow-up, MICA led to significant improvement in pain and radiographic scores.Levels of Evidence: III, retrospective study.

Short-Term Outcomes of Jones-Specific Implant Versus Intramedullary Screw and Plate Fixation for Proximal Fifth Metatarsal Fractures.

Although intramedullary screw fixation is commonly performed for proximal fifth metatarsal fractures, high rates of nonunion, refracture, and hardware prominence have been reported. The Jones Specific Implant (JSI) is a novel surgical implant which contours to the native curvature of the fifth metatarsal allowing for a more anatomic fixation. The purpose of this study was to compare short-term complication rates and outcomes of patients treated with the JSI to other fixation types such as plates and intramedullary screws. Electronic records were queried for adult patients with proximal fifth metatarsal fractures who underwent primary fixation from 2010 to 2021. All patients were treated by a foot and ankle fellowship-trained surgeon with intramedullary screws, plates, or JSI (Arthrex Inc., Naples, FL). Visual analog scale (VAS) and the American Orthopedic Foot and Ankle Score (AOFAS) were recorded and compared using univariate statistics. Eighty-five patients underwent fixation using intramedullary screw (n = 51, 60%), plate (n = 22, 25.9%), or JSI (n = 12, 14.1%) with a mean follow-up of 11.1 ± 14.6 months. The total cohort demonstrated a significant improvement in VAS pain (p < .0001) as well as AOFAS (p < .0001) scores. When comparing the cohort treated with JSI and the cohort treated with all other types of fixation, there were no significant differences in postoperative VAS or AOFAS scores. Only 3 complications, one with JSI (3.5%) required removal of the symptomatic hardware. The JSI is a novel treatment for proximal fifth metatarsal fractures, with similar early outcomes and complication rates when compared with intramedullary screw and plate fixation.

Metal Hypersensitivity Following Total Ankle Arthroplasty: Case Series and Literature Review.

Metal hypersensitivity following total ankle arthroplasty (TAA) is an underreported complication that can manifest as dermal, systematic, and orthopaedic-specific symptoms. It is critical to recognize that metal hypersensitivity is a diagnosis of exclusion; only after all other potential sources of failure, such as loosening or infection are ruled out, can this diagnosis be considered. Aside from imaging and common laboratory analysis, skin patch testing, leukocyte migration inhibition test (LMIT), and lymphocyte transformation test (LTT) are the testing options available for metal allergy. With regards to management of metal hypersensitivity, nonoperative modalities involving topical dermatological management are generally preferred. Severe cases of metal allergy may necessitate operative management consisting of explantation of the implant and either revision TAA with a custom hypoallergenic implant or conversion to an ankle fusion. We present 3 cases of presumed metal hypersensitivity following TAA. In all 3 cases, other forms of TAA failure were carefully ruled out. One patient underwent explantation and conversion to hypoallergenic implant, 1 patient underwent explantation and ankle arthrodesis with hypoallergenic hardware, and 1 patient elected for conservative care. In patients who underwent explantation and conversion to hypoallergenic hardware, no further symptoms associated with metal allergy were noted. Additional research is necessary to improve diagnostic accuracy of metal allergy and make treatment options more effective and accessible.Level of Evidence: Retrospective case series, IV.

Effect of Arthroscopically Confirmed Syndesmotic Widening on Outcome Following Isolated Broström Operation for Chronic Lateral Ankle Instability.

BACKGROUND: Tibiofibular syndesmosis (TFS) widening sometimes is not evident on radiography but can be found under arthroscopy in chronic lateral ankle instability (CLAI). This study aimed to evaluate the effect of TFS widening severity on clinical outcomes and return to activities after isolated Broström operation in CLAI patients and to propose an indication for its surgical intervention. METHODS: A total of 118 CLAI patients undergoing diagnostic ankle arthroscopy and open Broström-Gould operation were included. Based on the middle width of TFS measured under arthroscopy, patients were divided into the TFS-2 group (≤2 mm, n = 44), the TFS-3 group (2-4 mm, n = 42), and the TFS-4 group (≥4 mm, n = 32). The time to return to recreational sport and work, Tegner activity score, and proportion of returning to preinjury sports at the final follow-up were evaluated and compared. Other subjective evaluations included the American Orthopaedic Foot & Ankle Society score, visual analog scale, and Karlsson-Peterson score. RESULTS: Among the 3 groups, the TFS-4 group demonstrated the longest mean time to return to work and recreational sports, with the lowest proportion returning to preinjury sports. The TFS-4 group showed a significantly higher rate of sprain recurrence (12.5%) than the other 2 groups (P =.021). All the other subjective scores significantly improved after the operation without differences among the 3 groups. CONCLUSION: Concomitant severe syndesmotic widening adversely affects the return to activities after Broström operation in CLAI cases. The CLAI patients with a middle TFS width ≥4 mm were associated with delayed return to work and sports, a lower proportion of returning to preinjury sports, and more sprain recurrence, which might require further surgical intervention for syndesmosis in addition to Broström surgery.

Revision Surgery After Failed Index Synthetic Cartilage Implant Resurfacing for Hallux Rigidus: Single-Surgeon 5-Year Experience.

BACKGROUND: While metatarsophalangeal joint (MTPJ) arthrodesis is regarded as the gold standard treatment option for end-stage hallux rigidus (HR), synthetic cartilage implant (SCI) resurfacing has gained popularity. This study aimed to identify the SCI resurfacing failure rate for a single surgeon, while also comparing clinical outcomes of patients who underwent SCI replacement or MTPJ arthrodesis after failed index SCI resurfacing. METHODS: Health records were queried from 2016 to 2021 for patients with HR who were treated with SCI resurfacing by a single surgeon. Preoperative and postoperative range of motion, visual analog scale (VAS) pain scores, and hallux valgus angles were compared. A subgroup analysis was performed on patients who underwent revision with SCI replacement or MTPJ arthrodesis. SCI replacement included the use of bone graft, bone putty, or a custom 3D printed baseplate to prevent implant subsidence. RESULTS: A total of 219 SCI resurfacing procedures were performed by a single surgeon, including 23 revisions. When analyzing index procedures, an 8.2% revision rate was determined. The revision cohort (n = 23) consisted of 19 female patients and presented with a mean body mass index of 29.5 ± 5 kg/m2, mean age of 52.8 ± 11 years, mean follow-up duration of 22.3 (range, 3-54) months, and mean time to a revision surgery of 12.1 ± 12 (range, 1-50) months. Specifically, 12 procedures resulted in an SCI replacement, while 11 procedures resulted in arthrodesis. While all patients experienced significant improvement in their VAS pain scores (P < .001), the arthrodesis cohort experienced a greater improvement than the SCI revision cohort (P = .04). CONCLUSION: When analyzing SCI revision procedures, MTPJ arthrodesis reduced pain more significantly than SCI replacement. LEVELS OF EVIDENCE: Level IV: Retrospective case series.

Team Approach: Metal Hypersensitivity in Total Joint Arthroplasty.

¼: As total joint arthroplasty volume continues to grow nationwide, more uncommon complications such as metal implant hypersensitivity are reported with greater frequency in the literature. ¼: Metal hypersensitivity is a challenging diagnosis given the potentially vague symptomology. It should be considered a diagnosis of exclusion, necessitating careful consideration of other potential etiologies of a failing implant before arriving at the final diagnosis of metal hypersensitivity. ¼: Patients can experience substantial morbidity from implant rejection and in severe, refractory cases may even require revision arthroplasty and conversion to a hypoallergenic implant. ¼: Given the complex nature of the condition, successful treatment of metal hypersensitivity to orthopaedic implants is best achieved through the use of a multidisciplinary, team-based approach. Immunologists, radiologists, and infectious disease physicians as well as orthopaedic surgeons and mechanical engineers are all vital in appropriate diagnosis and treatment of the condition.

Outcome of Turf Toe Injuries in NFL Players.

The increase in artificial turf in the 1970s was thought to have contributed to increased incidence of turf toe injury in National Football League (NFL) players. To our knowledge, there are no publications that have analyzed the impact of this injury on performance. This is a retrospective case series. Online resources were used to identify NFL players who sustained a turf toe injury between the 2011 and 2014 seasons. The performance of each offensive skill player was analyzed separately by calculating their power rating (PR) over 6 seasons. Injured offensive skill players were then compared to a control group consisting of all RBs and WRs without a turf toe injury who competed in the 2012 season. Seventy-one turf toe injuries were identified. Twenty-nine occurred on grass, 29 on turf and the playing surface of 13 injuries could not be identified. The average PR prior to injury was 105.7/season (7.3/game), 87.3 (6.9/game) for the season of injury and 115.5 (8.1/ game) for postinjury seasons. The PR was not significantly different after a turf toe injury compared to before injury or to uninjured control player. There was no significant difference in NFL players' performances after turf toe injury based on power ratings.

Bilateral Achilles Tendon Ruptures in the NFL.

Background: Achilles tendon ruptures (ATR) can have devastating results for athletes in the National Football League (NFL). While many studies have examined the effects of an ipsilateral ATR, there are no reports on the impact of bilateral ATRs on NFL athlete performance. Methods: Publicly available online injury data for NFL athletes who sustained bilateral ATRs between the start of the 2007 season and the start of the 2021 season were queried using online news and sports analysis web sources. Results: After applying inclusion and exclusion criteria, 5 NFL athletes were identified. The findings demonstrated a significant difference in age at the time of each rupture (27.8 vs 30.4 years, P < .01) along with a decreasing trend in the number of Pro Bowl nominations following successive ATRs (P = .027). There were no differences reported for the duration and number of games missed during either rehabilitation period following an ATR. Upon analyzing defensive NFL athletes, forced fumbles was the only performance metric that significantly changed across successive ATRs. Conclusion: Overall, bilateral ATRs can adversely impact an NFL player's performance and further research should be performed to continue analyzing the effects of bilateral ATRs on these athletes.Level of Evidence: 4.

Early Outcomes of Combined Total Ankle Total Talus Replacement Using a 3D-Printed Talus Component With Hindfoot Arthrodesis.

Late-stage talar avascular necrosis (AVN) results in devascularization of the talus with osteonecrosis and subchondral collapse. A combined total ankle and total talus replacement (TATTR) with hindfoot arthrodesis may be utilized for end-stage talar AVN with tibiotalar and hindfoot joint arthritis. The purpose of this study is to evaluate the short-term outcomes of combined TATTR with hindfoot arthrodesis. Patients who underwent a combined TATTR or TTR with a hindfoot arthrodesis (subtalar with or without talonavicular arthrodesis) from 2016 to 2020 were retrospectively reviewed. Patient demographics, comorbidities, and surgical data were collected. Outcomes included the Visual Analog Scale (VAS) scores, range of motion, radiographic parameters, union rates, and complications. A total of 18 patients were reviewed. Nine patients were included with an average of 19.4 months follow-up. Significant postoperative improvements were observed in VAS scores (P < .001), ankle plantarflexion (P = .04), talocalcaneal height (P = .03), and tibiotalar alignment (P = .02). All patients achieved a successful union of their subtalar and talonavicular joints arthrodesis. There was one reoperation for a persistent varus ankle deformity. This is the first study to evaluate the clinical outcomes, radiographic outcomes, and union rate in combined TATTR with hindfoot arthrodesis. The early results demonstrated significant clinical improvement with 100% hindfoot union rate and no prosthetic failure.Level of Evidence: IV.

Pain Reduction With AbobotulinumtoxinA for the Treatment of Hallux Valgus in Adult Participants: Results of a Randomized and Placebo-Controlled Phase 2 Trial.

AbobotulinumtoxinA (aboBoNT-A, Dysport® [Ipsen, Paris, France]) inhibits acetylcholine release at the neuromuscular junction and may modulate pain signaling in hallux valgus (HV). This randomized study (NCT03569098) included a double-blind phase (aboBoNT-A 300U, 500U or placebo injections into forefoot muscles) and an open-label aboBoNT-A treatment period in participants with an HV diagnosis and no HV surgery. The primary endpoint was change from baseline in numeric pain rating scale (NPRS) score at week 8. Secondary endpoints included change in NPRS (other time points) and proportion of participants with ≥20% reduction from baseline NPRS (responders). Post-hoc analyses assessed number of days in a 7-day evaluation period that participants spent in a lower pain state than at baseline. Participants received aboBoNT-A 300U (n = 63), 500U (n = 60) or placebo (n = 63). Superiority to placebo was not observed with either aboBoNT-A dose at week 8, thus the primary endpoint was unmet. At week 12, a trend toward efficacy was observed with aboBoNT-A 500U versus placebo and the proportion of participants with ≥20% reduction from baseline NPRS was greater with aboBoNT-A 500U versus placebo (p = .006). Participants in the aboBoNT-A 500U group spent more days with lower NPRS than their lowest baseline score, and with NPRS ≥2 points lower than their mean baseline NPRS at weeks 8 and 12 versus placebo (all p < .05; post-hoc). AboBoNT-A was well tolerated. Although the primary endpoint was unmet, other endpoints showed a nominal advantage for aboBoNT versus placebo for treatment of HV-related pain, particularly at week 12. Further clinical evaluation is needed to establish whether botulinum toxins represent a viable non-operative treatment option for HV-associated pain. PLAIN LANGUAGE SUMMARY: Hallux valgus is the medical name for a bunion, a foot deformity that can worsen over time. Patients with bunions experience pain and walking can become difficult, which can affect their quality of life. Foot support aids (e.g., braces, splints and inserts) are available, but surgery is the standard treatment. This study looked at how injections of a specific type of botulinum toxin, called abobotulinumtoxinA or "aboBoNT-A", into the foot may help to reduce pain in patients with bunions. The study included 186 patients aged 18 to 75 years who had not had surgery on their bunion. The researchers looked at how well the injections worked using scales that measure the pain levels the patient experienced. The main outcome was whether patients who had aboBoNT-A injections had less pain after 8 weeks than they did before treatment. The study included patients who were injected with saltwater (no treatment) to check that any treatment effect was real. Researchers also looked at the results after 12 weeks, as well as how many patients had less pain after treatment than before and how many days in a given week patients experienced less pain after treatment than they did before. There was no reduction in pain levels with aboBoNT-A injections after 8 weeks compared with no treatment. However, the other study outcomes suggested that aboBoNT-A resulted in a small benefit compared with no treatment, especially after 12 weeks. Further medical research is needed to establish whether botulinum toxins represent an alternative treatment to surgery for the pain associated with bunions.

3D-Printed Total Talus Replacement After Free Vascularized Medial Femoral Condyle Osteocutaneous Flap for Avascular Necrosis of the Talus Leads to Poor Clinical Outcomes: A Case Series.

INTRODUCTION: Avascular necrosis (AVN) of the talus is 1 of the most difficult foot and ankle pathologies to diagnose and manage. The purpose of this study was to report on the functional outcomes of 3D-printed total talus replacement (TTR) in 2 patients with talar AVN who both underwent a failed revascularization. METHODS: This is a case series of 2 patients with TTR after a failed revascularization and a comparison group of 25 patients with primary TTR. Clinical and functional outcomes are used to compare both groups. RESULTS: Patient 1 had a postrevascularization Visual Analogue Scale (VAS) pain score of 9. Imaging showed failure of the medial femoral condyle to incorporate with talar fragmentation. Patient underwent TTR at 5 months postoperatively. At 2 years postoperatively, the patient underwent a cavovarus foot reconstruction; however, patient continued to suffer from ankle pain (VAS 6) and ultimately underwent below knee amputation at 3 years after the TTR. Patient 2 initially underwent a core decompression for a talar bone infarct followed by revascularization procedure at 6 months postoperatively due to persistent pain and bony infarcts. At 18 months postrevascularization, the patient had a VAS pain score of 9 and progression of the AVN. She underwent a TTR. At 1-year follow-up, the VAS pain score was 8. Both patients had an ankle plantarflexion of 30° at their last TTR follow-up. The comparison group consisted of 25 patients who underwent 3D-printed TTR with mean postoperative VAS score and ankle plantarflexion of 3.7° and 41.8°. CONCLUSION: Patients 1 and 2 demonstrated reduced plantarflexion and ankle motion after TTR relative to the comparison group which improved in both physical assessments. The first patient needed a below knee amputation for persistent pain. Patient 2 showed less improvement in all the foot and ankle outcome scores as compared with the primary TTR group.

Inflammatory Aseptic Arthropathy in the Setting of COVID-19: A Case Report.

Introduction: COVID-19 is among the most deleterious pandemics that the world has ever faced. It is known that SARS-CoV-2 engenders its effects by triggering a massive immune response identified as a "cytokine storm," but the full extent of clinical manifestations of the disease is still not understood. Case Presentation: We report the first case of a patient with COVID-19 infection who developed inflammatory (IL) aseptic arthropathy. The patient is a South Asian male of Indian origin residing in the United States. Conclusion: This case demonstrates the importance of remaining vigilant about the new and unique manners, in which COVID-19 may present itself. Providers should be aware of the possible development of IL arthropathy in patients with the disease.

Burnout Rates Among General Orthopedic Surgeons and Subspecialists: A Pilot Study.

Burnout among physicians is a syndrome of emotional exhaustion, de-personalization, and reduced sense of personal accomplishment that can negatively affect personal relationships, physician well-being, and patient outcomes. Although burnout rates of up to 50% to 60% among orthopedic surgeons have been reported, no studies have evaluated burnout among orthopedic generalists and subspecialists. The primary goal of this study was to examine the prevalence of burnout among orthopedic disciplines. We conducted a multicenter study from March 2019 through December 2019 involving 149 orthopedists. An abbreviated Maslach Burnout Inventory-Human Services Survey was used to measure burnout. Demographic information, personal characteristics, professional characteristics, family life and spousal support, and depression were also assessed. The mean rate of burnout among all respondents was 62%, whereas 16.77% screened positive for depression. Subspecialties with the highest rates of burnout were oncology (100%), sports medicine (68%), and trauma (63%). Similarly, trauma (50.00%), oncology (40.00%), and general orthopedics (20.00%) had the highest positive depression screening rates. In contrast, shoulder and elbow (50%), pediatric (52%), and foot and ankle (54%) specialists had the lowest rates of burnout, whereas shoulder and elbow (0.00%), spine (0.00%), and sports medicine (6.50%) specialists had the lowest rates of positive depression screening. Older age, higher debt load, and oncology subspecialty were associated with increased burnout risk. This study sought to determine burnout rates within each orthopedic discipline, with a secondary aim of disclosing contributing factors. Trauma and oncology had the highest rates of burnout and positive depression screening. Because this study represents a small orthopedic cohort, larger studies are needed to appropriately manage burnout in the future. [Orthopedics. 2022;45(6):333-339.].

Orthopaedic Foot and Ankle Surgery Leadership Trends: A Cross-Sectional Study of Fellowship Directors and Division Chiefs.

Background: In orthopaedic surgery departments, foot and ankle fellowship directors are tasked to create a robust clinical curriculum for trainees, while division chiefs manage the division's delivery of patient care. The primary aim of this study was to describe characteristics of foot and ankle surgery fellowship directors and division chiefs in an effort to recognize trends or disparities in leadership traits. Methods: The American Orthopaedic Foot and Ankle Society (AOFAS) fellowship directory for 2021 to 2022 was reviewed for AOFAS-recognized fellowship programs in the United States. Between March 2021 and June 2021, 48 fellowship directors and 23 publicly recognized division chiefs were administered an electronic survey to collect demographic, educational, and professional data. Univariate and bivariate statistical analyses were performed. Results: A total of 42 of the 48 (87.5%) fellowship directors and 18 of the 23 (78.3%) division chiefs responded to the questionnaire. Of the 48 fellowship directors, 45 (93.8%) were male, 43 (89.6%) identified as Caucasian, their average age at leadership appointment was 42.6 ± 7.5 (range, 32-70) years, and the average time between fellowship graduation and leadership appointment was 9.9 ± 7.8 (range, 0-36) years. Of the 23 chiefs, 22 (95.7%) were male, 20 (87.0%) identified as Caucasians, their average age at leadership appointment was 41.7 ± 7.8 (range, 32-53) years, and the average time between fellowship graduation and leadership appointment was 9.8 ± 6.8 (range, 2-21) years. The average H-index for the chiefs was greater than that of the fellowship directors (18.4 vs 13.4, P = .0373) when controlling for years of training>. Conclusion: The majority of current leaders identify as middle-age Caucasian males, demonstrate high research productivity, and have attended a select number of the same residency and fellowship training programs. By demonstrating the lack of diversity within foot and ankle surgery leadership, this study serves as a call to action for making inclusivity a priority.Levels of Evidence: Level IV: Cross-sectional study.

Achilles: Failed Acute Repair.

Acute Achilles tendon ruptures are commonly managed with surgical repair. This particular surgery is prone to rerupture, wound complications, deep vein thrombosis, and sural nerve injuries. In this chapter the authors discuss complications, how to avoid them, and ultimately how to manage complications with your patients.

Histologic grading correlates with inflammatory biomarkers in tibialis posterior tendon dysfunction.

BACKGROUND: It has been theorized that tibialis posterior tendon dysfunction (TPTD) is a degenerative process unrelated to inflammation. The purpose of this study was to determine if inflammatory cytokines, matrix metalloproteases (MMPs), and glutamate were elevated in diseased tibialis posterior tendons (TPTs). METHODS: Matched diseased TPT, TPT insertion, and flexor digitorum longus (FDL) samples were collected from 21 patients. The samples were individually incubated in media, which was analyzed for inflammatory cytokines, MMPs, and glutamate. Histology and statistical analyses were performed. RESULTS: Diseased TPT and TPT insertion were significantly elevated compared to transferred FDL in eight inflammatory markers (p < 0.005). Only the diseased TPT was significantly elevated compared to the transferred FDL tendons for glutamate (p < 0.01). Histologic grading correlated with inflammatory cytokine levels. CONCLUSION: Diseased TPT and TPT insertion demonstrated significantly elevated levels of inflammatory markers compared to the transferred tendons used as controls, suggesting a role for inflammation in the disease process. The amount of inflammation correlated with increased tendon degradation. LEVEL OF EVIDENCE: Level III.
