Background: Preoperative oral antibiotic use in patients undergoing foot and ankle surgery is standard practice, but no consensus has been reached regarding the efficacy of postoperative oral antibiotics. The purpose of this study was to determine whether postoperative oral antibiotics reduce the rate of surgical site infections (SSIs) in patients, with and without comorbidities, undergoing foot and ankle surgery. Methods: A retrospective chart review was conducted identifying patients who underwent foot and ankle surgery by 4 fellowship-trained, foot and ankle orthopaedic surgeons between January 1, 2015, and January 1, 2019. Patients were divided into 2 groups: those who received postoperative oral antibiotics (group 1) and those who did not (group 2). Two surgeons routinely prescribed postoperative oral antibiotics, and 2 did not. Demographics, comorbidities, and procedure complexity based on surgical site and Current Procedural Terminology code were recorded from the charts. The primary outcome was postoperative infection (superficial or deep) within 6 months after surgery. Patients with antibiotic use prior to surgery, preoperative infection, or lack of follow-up >6 weeks were excluded. Multivariate logistic regression modeling was used to analyze differences in infection rate and severity. Results: Chart review identified 3631 patients, 1227 of whom did not receive postoperative oral antibiotics whereas 2394 patients did. Routine postoperative oral antibiotic use did not significantly affect postoperative infection rates or severity. However, all covariates studied (diabetes, hypertension, obesity, tobacco use, alcohol use, rheumatoid conditions, and age) influenced postoperative infection rates and severity. Conclusion: The results of this study indicate that postoperative oral antibiotics are not associated with differences in infection rates or severity. We do not recommend routine use in foot and ankle surgery.

Background:The purpose of this article was to review the basic science pertaining to the harmful effects of cigarette smoke, summarize recent clinical outcome studies, and examine the benefits of smoking cessation and the efficacy of current smoking cessation strategies.Methods:The literature concerning basic science, clinical outcomes, and smoking cessation was reviewed; over half (56%) of the 52 articles reviewed were published in the last 5 years.Results:Smoking is associated with low bone mineral density, delayed fracture union, peri-implant bone loss, and implant failure. Orthopedic surgical patients who smoke have increased pain and lower overall patient satisfaction, along with significantly increased rates of wound healing complications.Discussion/Conclusion:Active smoking is a significant modifiable risk factor and should be discontinued before foot and ankle surgery whenever possible. Orthopedic surgeons play an important role in educating patients on the effects of smoking and facilitating access to smoking cessation resources.Level of Evidence:Level V, expert opinion.

Background: This study looked at the effect of patient demographics, insurance status, education, and patient opinion on whether various orthotic footwear prescribed for a variety of diagnoses were received by the patient. The study also assessed the effect of the orthoses on relief of symptoms. Methods: Chart review documented patient demographics, diagnoses, and medical comorbidities. Eligible patients completed a survey either while in the clinic or by phone after their clinic visit. Results: Of the 382 patients prescribed orthoses, 235 (61.5%) received their orthoses; 186 (48.7%) filled out the survey. Race and whether or not the patient received the orthosis were found to be significant predictors of survey completion. Race, type of insurance, and amount of orthotic cost covered by insurance were significant predictors of whether or not patients received their prescribed orthoses. Type of orthosis, diabetes as a comorbidity, education, income, sex, and diagnosis were not significant predictors of whether the patient received the orthosis. Qualitative results from the survey revealed that among those receiving their orthoses, 87% experienced improvement in symptoms: 21% felt completely relieved, 66% felt better, 10% felt no different, and 3% felt worse. Conclusion: We found that white patients had almost 3 times the odds of receiving prescribed orthoses as black patients, even after controlling for type of insurance, suggesting race to be the primary driver of discrepancies, raising the question of what can be done to address these inequalities. While large, systematic change will be necessary, some strategies can be employed by those working directly in patient care, such as informing primary care practices of their ability to see patients with limited insurance, limiting blanket refusal policies for government insurance, and educating office staff on how to efficiently work with Medicare and Medicaid.

To determine patient satisfaction and safety with wheeled knee walkers, we performed a retrospective, observational, and descriptive study. Inclusion criteria were age ≥18 years, unilateral foot or ankle surgery, non-weightbearing status, and being given the option of using the knee walker. Surveys were sent to eligible patients, and chart review included only those patients who returned surveys. Primary endpoints were occurrence and frequency of falls. Secondary endpoints were patient demographics, comorbidities, knee walker characteristics, duration of use, and patient satisfaction. We also attempted to identify associations between falls and patient characteristics. Eighty participants, 51 females and 29 males, responded adequately to the survey. The mean age of respondents was 55.6 ± 13.0 years and their mean body mass index (BMI) was 30.2 ± 5.9 kg/m2. Most used a steerable, 4-wheeled knee walker. Almost half (46%) had no prior experience with any type of walking aids, and none had experience using a knee walker. Two thirds (66%) did not receive any instruction on usage of the knee walker. Thirty-four (43%) of the 80 respondents fell while using the knee walker; nearly two thirds (62%) of those who fell reported multiple falls. Sixteen (55%) of 29 males compared to 18 (36%) of 50 females reported falling (p = .097). There was no statistical association between falls and age, BMI, or number of comorbidities. Most respondents (91%) who fell still reported satisfaction with the knee walker. Nearly half (43%) experienced falling, and nearly two thirds (64%) of those who fell had multiple falls.

Platelet-rich plasma has become an increasingly popular treatment option within the orthopedic community to biologically enhance and stimulate difficult-to-heal musculoskeletal tissues. This review evaluates the recent literature on platelet-rich plasma use in the treatment of foot and ankle pathologies. Recent literature has demonstrated platelet-rich plasma to have a possible benefit in the treatment of Achilles pathology, chronic plantar fasciitis, osteochondral lesions of the talus, ankle osteoarthritis, and diabetic foot ulcers. However, given the lack of standardization of platelet-rich plasma preparations and protocols and the predominance of low-quality studies, no definitive treatment indications exist. Platelet-rich plasma is a promising treatment option, but at present, there is only limited clinical evidence supporting its use in foot and ankle applications.

Background:The purpose of this study was to examine factors associated with pain after elective ankle and hindfoot reconstruction.Methods:Patients who underwent major ankle or hindfoot reconstruction over a 3-year period were identified. Retrospective chart review determined patient demographics, comorbidities, surgeries, tobacco, alcohol, and narcotic use, chronic pain, and mood disorders. Primary outcomes were cumulative amount of narcotic prescribed (morphine milligram equivalent dose) in the initial 90-day postoperative period, beyond 90 days, and visual analog pain score (VAS) at a minimum of 1-year follow-up. One hundred thirty-two patients (139 operations) met the inclusion criteria.Results:The average narcotic amount prescribed in the initial 90 days after surgery was 1711 mg (morphine equivalent), and narcotic prescriptions were required after 52 surgeries (35%) past 90 days. Preoperative narcotic use ( P < .01), chronic pain disorder ( P = .02), and mood disorder ( P < .01) were significant risk factors for continued narcotic use past 90 days. Tobacco use ( P = .01) and chronic pain disorder ( P < .01) also were significant risk factors for increased initial postoperative narcotic use. The average VAS score in 91 patients at an average of 2.7-year follow-up was 2.1. Mood disorder was a risk factor for increased VAS ( P < .01). No other associations were noted.Conclusion:Patients being treated for chronic pain, diagnosed with a mood disorder, taking any amount of narcotics preoperatively, or using tobacco products had a statistically significant increased risk for pain postoperatively. The presence of risk factors should prompt physicians to discuss pain management strategies before surgery.Level of Evidence:Level III, comparative series.

This review article provides an overview of talus fractures. Special attention is given to the clinical literature that evaluates the timing of surgical management for displaced talus fractures. Several series support delayed definitive fixation for talus fractures, suggesting displaced fractures do not necessitate emergent surgical fixation.

Background. The purpose of this study was to examine medical, social, and psychological factors associated with complications and reoperation after foot and ankle reconstruction. Methods. A retrospective chart review was conducted of 132 patients (135 feet; 139 operative cases) who had elective foot and ankle reconstruction. Medical, social, and psychological variables were documented. Primary outcomes included complications and reoperations. Results. The overall complication rate was 28% (39/139), and the reoperation rate was 17% (24/139). Alcohol use (P = .03) and preoperative narcotic use (P = .02) were risk factors for complications, with delayed wound healing more frequent in alcohol users (P = .03) and deep infection (P = .045) and nonunion (P = .046) more frequent preoperative narcotic use. Deep infection also was more frequent in tobacco users (P < .01). Older patients were less likely to undergo reoperation (risk of reoperation increased with age). Other variables were not associated with increased complications. Conclusion. Patients who consumed alcohol or had been prescribed any amount of narcotic within 3 months preoperatively were at increased risk for complications. Patients who smoked were more likely to have a wound infection. Surgeons should be aware of these factors and counsel patients before surgery.Levels of Evidence: Level III: Retrospective comparative study

Category: Ankle, Hindfoot, Midfoot/Forefoot, Trauma, Assistive devices, Post-operative Introduction/Purpose: Patients use assistive devices to mobilize during periods of non- or partial- weight bearing after lower extremity surgery or injury. The wheeled knee walker has grown in popularity, but there is a paucity of literature about this assistive device. The goal of this study is to quantify and describe patient use of knee walkers after foot and ankle surgery in the group practice of foot and ankle surgeons at multiple sites and a single institution. Primary endpoints include occurrence of falls, frequency of falls, and injury. Secondary endpoints include patient demographics (gender, age, BMI), comorbidities, knee walker characteristics, duration of use, and satisfaction in this population. This study also attempts to determine if any associations exist between knee walker-related falls and the above-mentioned factors. Methods: We performed a retrospective, observational and descriptive study examining the use of knee walkers in adult patients after a foot and ankle surgery. Inclusion criteria were patients =16 years with unilateral foot and ankle surgery, physician- instructed non-weight bearing status, and given the option of using the knee walker from March 2015 to April 2016. With institutional review board approval, paper and electronic surveys were sent to 691 patients. Informed consent and data were collected from June 2016 to January 2017. Using the survey, we collected information on knee walker characteristics, duration of use and payment of knee walker, occurrence and frequency of falls, adverse events, satisfaction and recommendation for or against the use of knee walker. We performed a chart review to obtain demographic data and comorbidities. To determine association between falls and factors collected, Pearson Chi-Square analysis was utilized for discrete variables and Independent samples T-Test for continuous variables. Results: 79/671 participants responded (12% response rate). The average age was 53.9±13.7years (range:17-85) and average BMI 30.7±5.9kg/m2 (range:18.2-48.9). 35/78(45%) participants had =3 comorbidities. Most used a steerable, 4-wheeled knee walker [74/76(96%) steerable, 66/76(87%) 4-wheeled]. Respondents used knee walkers on average 6.9±5.3weeks and 5.7±3.8hours/day. Two-thirds [51/76(67%)] did not receive instruction on usage of the knee walker. 32/73(44%) fell while using the knee walker, and nearly two-thirds [20/31(65%)] of those who fell reported multiple falls. 64/74(86%) participants were satisfied, 2/74(2.7%) felt neutral and 8/74(11%) were dissatisfied with the knee walker. 15/27(56%) male compared to 16/45(36%) female participants reported falling (p=0.097). There was no statistical association between falls and age, falls and BMI, or falls and =3 comorbidities. 30/32(94%) participants who fell still reported satisfaction with the knee walker. Conclusion: To our knowledge, this is the first study reporting on wheeled knee walker usage in a clinical population. A significant portion (44%) of knee walker users experienced falling, and nearly two-thirds (65%) of those who fell experienced multiple falls. Despite these rates of falling, there were high satisfaction rates overall (86%), and among those who fell (94%). We did not find statistical association between falls and risk factors collected. This institution currently has an ongoing prospective knee walker study to examine knee walker usage and characteristics, patient factors, adverse events and the association between adverse events and possible risk factors.

Category: Sports Introduction/Purpose: There remains controversy over the ideal implant for intramedullary screw fixation of fifth metatarsal Jones fractures. Promising results have separately been reported for both indication-specific partially threaded screws and headless compression screws. The purpose of this study was to compare clinical and radiographic results between Jones fracture patients treated with indication-specific partially threaded screws to variable-pitched headless compression screws. We also evaluated the association of various patient and fracture characteristics with surgical failure. Methods: We performed a retrospective review and comparative analyses of all Jones fractures treated with primary intramedullary screw fixation by 4 foot and ankle fellowship-trained orthopaedic surgeons at a single institution from 1995 through 2015. Exclusion criteria included concomitant foot or ankle procedures and revision surgery. Charts were reviewed for patient and injury characteristics, implant, and postoperative course. Serial radiographs were examined for fracture classification (Torg and anatomic zone) and radiographic union. Primary endpoint was number of surgical failures, defined as delayed union, nonunion, or refracture. Secondary endpoints included time to each of radiographic union, weight bearing, and pain resolution. Data were analyzed using independent T test, one-way ANOVA, chi-square, and correlation analyses with significance defined as p < 0.05. Results: Fifty-nine feet were reviewed with mean age 30 years and follow-up 9.6 months. Forty-seven received a partially threaded screw (PT) and 12 feet a headless compression screw (HC). The PT group had more failures (10/47, 21.3% vs. 1/12, 8.3%; p=0.31) and more weeks to full weight (4.2 vs. 3.3, p=0.06), without significant differences in time to radiographic union or pain resolution. Most failures were delayed unions. Pooled union rate was 96.6%. Correlated with failure were age (r=0.469, p < 0.001), diabetes (r=0.390, p=0.002), and BMI (r=0.281, p=0.03), without significant correlation for tobacco, gender, or weight. Compared to Torg 1 and 2, Torg 3 fractures had greater time to pain resolution and radiographic union, age, weight, and BMI. No differences were found between zone II and III fractures. Conclusion: To our knowledge, this is the first reported clinical comparison between indication-specific partially threaded screws (PT) and headless compression screws (HC) for treating Jones fractures. This is also one of the largest clinical series on the subject. The two groups had similar clinical and radiographic results, both with high union rates. While most failures were delayed unions that ultimately healed, the 21% failure rate in the PT group is concerning and may warrant further investigation. Increasing patient age, diabetes, and BMI were associated with worse outcomes. These data support headless compression screw fixation as a viable treatment for Jones fractures.

Background Total ankle replacement has increased in popularity in the management of severe tibiotalar arthritis. Most previous clinical reports focused on mobile-bearing designs. This study evaluates early radiographic and clinical results of the Salto fixed bearing design. Methods Twenty-three Salto fixed-bearing implants were prospectively studied. Records were reviewed for clinical outcome scores (VAS, AOFAS, SF36), subsequent surgeries, complications, radiographic data and implant survivorship. Average follow-up was 36 months. Results Statistically significant improvements in VAS, AOFAS ankle/hindfoot scores, and SF36 scores were shown at an average of 3 years postoperatively. At 3 years followup, survivorship of the implant was 82.6% with any reoperation as the endpoint and 95.6% for revision or removal of components. Seven patients had radiolucencies around the implant, one of which required revision to arthrodesis. Conclusion The fixed-bearing Salto ankle replacement has comparable early radiographic and clinical results to reports of the mobile-bearing Salto of comparable followup. Level of evidence: Level IV

Background: Diabetic peripheral neuropathy is now well recognized as the most common cause of Charcot arthropathy of the foot and ankle, but it may be associated with other peripheral neuropathies. While not well known, it is well documented that rheumatoid arthritis is correlated with peripheral neuropathy. However, despite rheumatoid neuropathy, Charcot arthropathy has never been associated with rheumatoid arthritis. We report a series of Charcot arthropathy patients with concomitant rheumatoid arthritis. Methods: The medical records of patients treated between 1986 and 2009 with Charcot arthropathy and rheumatoid arthritis were reviewed. Recorded data included neuropathy risk factors, medications, history of ulcerations, ambulatory status, shoe wear, and treatment course. Radiographs of Charcot joints were categorized according to the Brodsky anatomic classification. Patient care was based on published treatment algorithms, emphasizing accommodative, nonoperative treatment with selective surgical interventions. Surgery was indicated for recalcitrant, nonhealing lesions of the soft tissue and/or unbraceable, nonplantigrade feet. A successful outcome was considered an ambulatory patient without amputation and a closed skin envelope at last follow-up. Results: Four men and 16 women met the diagnostic criteria, resulting in 33 feet in the series. Average age was 61 years, and average follow-up was 4.3 years. In addition to rheumatoid arthritis, 4 patients (7 feet) had hypothyroidism, 4 patients (6 feet) had diabetes, 1 patient (2 feet) had megaloblastic anemia and diabetes, and 1 patient (1 foot) had hypothyroidism and diabetes; however, 17 feet (52%) had no known sources for neuropathy. Charcot involvement was type 1–midfoot in 21 feet (64%), type 2–hindfoot in 7 (21%), type 3a–ankle in 4 (12%), and type 3b–calcaneus in 1 (3%). Twenty-three feet (70%) were treated with conservative modalities. Ten feet (30%) required 15 surgeries, of which an exostectomy was the most common procedure. Of the 33 feet, 3 had persistent ulcerations and 1 underwent major amputation, representing 4 failures. Conclusions: Raising awareness within the orthopaedic community, we report a Charcot arthropathy population with a concomitant rheumatoid arthritis diagnosis, emphasizing a relationship between the 2 diseases. Through a conservative treatment regimen combined with selective surgical interventions, satisfactory outcomes were achieved in 88% of the rheumatoid Charcot feet. While several patients had additional neuropathy sources which could cause Charcot arthropathy (eg, diabetes), the majority of feet had no etiologies accounting for neuropathy or neuroarthropathy except rheumatoid arthritis. Further study is required to expand on this relationship between the 2 diseases. Level of Evidence: Level IV, retrospective case series.
