Category: Ankle Arthritis Introduction/Purpose: Recently, there have been many reports on the relationship between depression and clinical outcome of knee or hip arthroplasty. However, there is no study on the association between depression and total clinical outcome of total ankle arthroplasty (TAA). This study investigated the relationship between depressive symptoms and clinical outcome after TAA. Methods: Forty patients who underwent TAA for end-stage ankle arthritis from July 2014 to July 2017 and were able to follow- up at least 12 months were selected. Depressive symptoms were evaluated using Center for Epidemiologic Studies Depression Scale (CES-D) and Patient Health Questionnaire-9 (PHQ-9). The subjects were divided into Depressive group and Non-depressive group, and the preoperative and postoperative clinical results were compared using a visual analogue scale (VAS), American orthopedic foot and ankle-hindfoot score (AOFAS). The preoperative and postoperative radiological results were also compared using anterior surface angle of distal tibia (TAS), talar tilt of ankle joint (TT), lateral surface angle of distal tibia (TLS), and heel alignment distance (HD). Results: The mean age of the patients was 61.6±18.2 years and the average follow-up period was 24.3±7.3 months. 13 subjects were in Depression group and 27 subjects were in Non-depression group. There was no statistical difference in baseline characteristics between the two groups. Additionally, there was no statistical difference in preoperative VAS and AOFAS between the two groups (p>.05). Preoperative and postoperative VAS and AOFAS showed statistically significant improvement in both groups (p<.05). However, the depressive group showed higher result in postoperative VAS than the Non-depressive group significantly (3.1±2.4 vs 1.4±2.3, p<.05). The postoperative AOFAS was also higher in the non-depressive group significantly (89.3±13.4 vs 95.0±8.1, p<.05). Both groups showed improvement in postoperative radiologic index. Preoperative and postoperative radiologic index showed no difference in both groups. Conclusion: The clinical outcome after TAA was poor in patients with depressive symptoms when compared to patients without depressive symptoms. Since depressive symptoms is a patient-specific factor that result in less improvement in clinical outcomes after TAA, clinical considerations for depressive symptoms are needed prior to TAA surgery.

Category: Ankle Arthritis Introduction/Purpose: Periprosthetic osteolysis in total ankle arthroplasty (TAA) is a substantial problem. It may cause implant failure and has potential to affect long-term implant survival. To prevent major revisional arthroplasty, it is important to make an early diagnosis of osteolysis and decide an appropriate timing of surgical intervention such as bone graft. We report our experience of bone graft for osteolysis after TAA associated with clinical and radiologic outcome. Methods: Between May 2004 and Oct. 2013, 238 primary TAA were performed on 219 patients. We excluded 37 ankles with follow-up less than 24 months; thus, 201 ankles in 185 patients with mean follow-up of 61.9 (range, 24-130) months were included in the study. Nineteen patients were treated with a total of 21 bone graft procedures for periprosthetic osteolysis after TAA. Of these patients, 12 (57.1%) were males with mean follow-up length after bone graft 35.0 months. Location of osteolysis, bone grafting method and clinical outcome parameters using visual analog scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) score were recorded. Results: Radiographs revealed total of 62 osteolysis lesions in 19 patients; 35 (56.5%) distal tibial lesions, 23 (37.0%) talar lesions. Autogenous iliac bone graft was used in 18 procedures (85.7%). The mean scores (and standard deviation) improved for the VAS from 4.8 ± 1.23 points before bone graft to 3.0 ± 0.94 points at the last follow-up (p<0.05); and for the AOFAS score from 76.8 ± 5.9 before bone graft to 84.3 ± 4.5 at the last follow-up (p<0.05). After 21 bone graft procedures, 6 demonstrated detection of newly developed osteolysis. One patient needed a repeat bone graft procedure with cementation after the primary bone grafting due to large cyst on distal tibia. There was no implant failure or major revisions after the bone graft. Conclusion: Bone graft for periprosthetic osteolysis may improve patient’s clinical outcome and give support to the structures surrounding the implant. Bone grafting in optimal timing may also improve implant survivorship. However, further study is needed for the etiology of newly developed painless osteolysis even after the bone graft.

Gait Function

Category: Ankle, Ankle Arthritis Introduction/Purpose: Operative treatment of end-stage ankle arthritis involves either ankle arthrodesis (AA) or total ankle arthroplasty (TAA). The theoretical benefit of TAA is the ability to preserve range of motion (ROM) at the tibiotalar joint. Previous studies have questioned whether it is justified to perform TAA over AA in stiff, arthritic ankles. However, a recent study showed that patients who underwent TAA with stiff ankles preoperatively experienced significant clinical improvement in range of motion and gait function compared to more flexible groups at 1-year follow-up. We retrospectively assessed these same gait and functional parameters to see if these improvements held up in long-term follow-up. Methods: A retrospective study of long-term, prospectively collected functional gait data in 33 TAA patients at a mean of 7.6 years postoperatively (range 4.8-13.3) used a multivariate regression model to determine the effect of ankle stiffness on the long- term, objective outcomes of TAA. Data was analyzed by quartiles (Q1, Q2+Q3, Q4) of preoperative sagittal ROM using one-way analysis of variance (ANOVA) to compare both preop and postop gait parameters. The two middle quartiles were combined to conform to distribution of the data. The multivariate analysis determined the independent effect of age, gender, BMI, years post- surgery, and preop ROM on every preop and postop parameter of gait. Results: Statistically significant differences were found in all three gait parameter categories, including temporal-spatial (step length and walking speed), kinematic (total sagittal ROM and maximum plantarflexion), and kinetic (peak ankle power). The stiffest ankles preoperatively (Q1) had the greatest absolute increase in total sagittal ROM postoperatively, +5.3o, compared to -1.3o (p<0.0174) in Q4 (most flexible). However, Q1 had the lowest absolute total postoperative sagittal ROM of 13.1 o, compared to 19.7 o (p<0.0108) in Q4. Q1 also had the lowest preoperative step length, walking speed, maximal plantarflexion, and peak ankle power when compared to the other subgroups. There was no difference in any of these same parameters postoperatively. BMI and years post-surgery had no effect on outcomes, while age and gender had a minimal effect. Conclusion: Preoperative range of motion was once again predictive of overall postoperative gait function in long-term follow-up at an average of 7.2 years. A greater degree of preoperative sagittal range of motion was predictive of greater postoperative sagittal range of motion in long-term follow-up. Patients with the stiffest ankles preoperatively once again had a statistically and clinically greater improvement in function as measured by multiple parameters of gait. This shows that the clinically meaningful improvement in gait function after total ankle arthroplasty holds up in long-term follow-up, even in the setting of limited preoperative sagittal range of motion.

Category: Ankle Arthritis Introduction/Purpose: Ankle arthrodesis remains a prominent treatment choice for ankle arthritis in a majority of patients. Long term studies have shown a compensatory development of ipsilateral adjacent joint arthritis after ankle arthrodesis, and some patients who receive an ankle arthrodesis develop pain in surrounding joints, or even at the fusion site. As total ankle arthroplasty (TAA) design, instrumentation, and techniques have improved, the use of total ankle arthroplasty has become more widespread. Very few studies have been published on conversion of ankle arthrodesis to ankle arthroplasty, but they have shown improved function and patient-related outcome scores. The purpose of this study was to assess the radiographic, clinical, and patient-reported outcomes of patients undergoing ankle arthroplasty after conversion from a CT-confirmed ankle arthrodesis. Methods: This was a retrospective cohort study of patients with previous CT-confirmed ankle arthrodesis who underwent conversion to total ankle arthroplasty. Minimum follow up was 1 year. Nonunions of ankle arthrodesis were excluded. AOFAS ankle-hindfoot score, foot function index (FFI), pain, revision surgeries, complications, and patient demographics were assessed. Radiographs prior to TAA, and at latest follow-up were also reviewed. Results: 10 patients were included in the study with an average age of 54.5 years. No implants had to be revised. 1/10 (10%) patients had to undergo secondary surgery for heterotopic ossification removal. The same patient had to undergo another subsequent surgery for posterior ankle decompression. 2/10 (20%) patients had a mild talar subsidence of the TAA at latest follow-up, with no patients having tibial subsidence. Talar osteolysis was noticed in 2 patients (20%) at latest follow-up, with no patients having tibial osteolysis. Only one patient (10%) was noted to have a mild valgus alignment of TAA with no varus malalignments. All radiographic changes noted were clinically asymptomatic. The average AOFAS total score was 58 (range 23,89). The mean FFI total score was 41.9 (range 0,90). Conclusion: Conversion of ankle fusion to TAA is a challenging operation but can be a viable option for patients with ongoing pain after an ankle arthrodesis. We noted low revision rates and few complications at 1 year.

Abstract Background Obesity is a risk factor for several cancers, including differentiated thyroid cancer (DTC). Moreover, it has also been investigated as a potential risk factor for aggressiveness of DTC, but the data gathered so far are conflicting. The aim of our study was to evaluate the relationship between body mass index (BMI), aggressiveness of DTC at diagnosis, and clinical outcome. Methods We evaluated 1058 consecutive DTC patients treated with total thyroidectomy and enrolled at the time of first radioactive iodine (131I) treatment. Patients were divided into 4 groups based on their BMI: underweight (&lt; 18.5 kg/m2), normal weight (18.5-24.9 kg/m2), overweight (25-29.9 kg/m2), and obese (≥ 30 kg/m2). Histological aggressiveness of DTC at the time of diagnosis and clinical outcome according to 2015 American Thyroid Association (ATA) guidelines were evaluated. Results No differences in histological features, ATA risk of recurrence, activity of 131I administered and prevalence of 131I avid metastatic disease after first131I treatment, have been demonstrated among the groups. Furthermore, at the end of follow up (median = 5.7 years), no differences were evident in the number of further treatments performed as well as in the clinical response. Conclusions In our study group of Caucasian subjects, we could not demonstrate any association between BMI and aggressiveness of DTC, neither at the time of diagnosis nor during follow-up. These data indicate that postsurgical assessment and therapeutic attitude for treatment and follow-up of DTC should be based on the class of risk applied to the general population, with no concern for BMI.

Abstract Background NHS was created in 1948 to redress the healthcare inequality through provision of universal healthcare service in the UK. However even of late, significant health inequality persists. Socioeconomic deprivation is known to result in increased overall morbidity and mortality. Aim To assess the impact of socioeconomic deprivation (as categorised by Scottish Index of Multiple Deprivation, SIMD) on the medical management and clinical outcomes of patients with ACS (NSTEMI/STEMI) who were treated with PCI Methods A retrospective study of NSTEMI/NSTEMI patients after inpatient treatment with coronary angiogram and PCI. The parameters include basic demographics, risk factors, LV EF on echocardiogram, lipid profile and discharge medication. Individual's socioeconomic deprivation index, as described SIMD was also recorded (1 – most deprived and 10 – least deprived), and accordingly placed into quintile (SIMD 1–2, 3–4, 5–6,7 –8, 9–10). Follow-up for 24 months. Clinical outcome assessed was composite endpoint event of MACE. Results 357 from the lowest quintile (SIMD 1–2), 319 from SIMD 3–4, 191 from SIMD 5–6, 120 from SIMD 7–8, and 99 from the highest quintile (SIMD 9–10) were included. No statistical difference exists between age or gender. No difference in past medical history (inclusive of hypertension, diabetes, dyslipidemia, family history. No difference in incidence of nicotine use. Prescription of aspirin, P2Y12 inhibitors (clopidogrel, ticagrelor or prasugrel) as well as secondary prevention medications (such as ace inhibitor/angiotensin II receptor blocker, beta blocker, statin and GTN) were good and not statistically different between all groups. No statistical difference exists between all groups relating to pre-discharge LV ejection fraction on echocardiogram or random cholesterol level check on admission. 24 months follow-up demonstrated composite endpoint of MACE was statistically higher among patients of lowest socioeconomic quintile (Kaplan Meier plot, p<0.001). Step-wise multiple regression analysis also confirmed multiple socioeconomic deprivation as an independent predictor for more adverse clinical outcomes (p<0.001, R2=14.5%). Patients from the least deprived quintile possess survival advantage almost 14-folds as compared to those of most deprived group (Odd-ratio 13.8 (95% CI: 39.4–48.5)). Summary After an ACS event, despite initial coronary intervention and subsequent optimal prescription of prognostically beneficial secondary prevention medications, patients from the lower socioeconomic group (as described by SIMD) are still more likely to experience readmission for cardiovascular death, non-fatal myocardial infarction and non-fatal stroke. Socioeconomic deprivation has been shown to be an independent predictor of adverse clinical outcome for those who survived initial ACS. Acknowledgement/Funding None

Category: Ankle Arthritis; Ankle Introduction/Purpose: Total ankle arthroplasty (TAA) has garnered significant interest and increased use over the past decade, with advancements made in both design and surgical technique. The main advantage of TAA for the surgical treatment of ankle arthritis is to preserve range of motion compared to ankle arthrodesis. Among the criteria guiding the choice between arthroplasty and arthrodesis, the long-term survival and postoperative outcomes are of crucial importance. The Salto Talaris is a fixed-bearing implant first approved in the US in 2006, and long-term survivorship data is limited. The purpose of this study is to determine minimum 5-year survivorship of the Salto Talaris prosthesis and causes of failure. In addition, we evaluate long-term radiographic and patient-reported outcomes. Methods: We retrospectively identified 86 prospectively followed patients from 2007 to 2014 who underwent TAA with the Salto Talaris prosthesis at our institution. Of these, 81 patients (84 feet) had a minimum follow-up of 5 years (mean, 7.1; range, 5 to 12). Mean age was 63.5 years (range, 42 to 82) and mean BMI was 28.1 (range, 17.9 to 41.2). Survivorship was determined by incidence of revision, defined as removal/exchange of a metal component. Chart review was performed to record incidences of revision and reoperation. Preoperative, immediate and minimum 5-year postoperative x-rays were reviewed; coronal tibiotalar alignment (TTA) was measured on standing AP radiographs to assess alignment of the prosthesis. A TTA of +-5° from 90° indicated neutral alignment, while <85° and >95° was considered varus and valgus alignment, respectively. Radiographic subsidence as well as presence and location of periprosthetic cysts were documented. Pre- and minimum 5-year FAOS domains were compared. Results: Survivorship was 97.6% with two revisions. One patient underwent tibial and talar component revision for varus malalignment of the ankle, another underwent talar component revision for aseptic loosening and subsidence. The rate of other reoperations was 19.5% (18) with the main reoperation being exostectomy with debridement for ankle impingement (12). Average preoperative TTA was 88.8° with 48 neutral (average TTA of 90.1°), 18 varus (82.3°) and 8 valgus (99.6°) ankles. Average postoperative TTA was 89.0° with 69 neutral (89.7°), 6 varus (83°), and 1 valgus ankle (99.3°). Radiographic subsidence was observed in one patient who underwent revision, and periprosthetic cysts were observed in 18 patients. There was significant improvement in all FAOS domains at final follow-up. Conclusion: This is the largest study to date dedicated to evaluating survivorship of the Salto Talaris prosthesis. Our data reflects a high survival rate and moderate reoperation rate with long-term follow-up of the Salto Talaris implant. We observed significant improvement in radiographic alignment as well as patient-reported clinical outcomes at minimum 5-year follow-up.

Category: Ankle, Ankle Arthritis, Pediatric Foot and Ankle Introduction/Purpose: Ankle valgus has been reported in 50% of patients with multiple hereditary exostoses (MHE) and, untreated, results in early arthrosis. Widening of the ankle mortise has also been reported; however, there has been a lack of data regarding its natural history and management. Alterations of mortise anatomy result in poor functional outcomes and accelerated arthrosis of the ankle. The aim of our study was to report the characteristics and outcomes of mortise widening in a group of patients with MHE. Methods: A total of 13 patients with MHE and mortise widening (16 ankles) were identified. Age, sex, BMI, laterality, origin of osteochondroma, pain, instability, clinical deformity, operative data, and complications were recorded. Mortise (M), Talocrural angle (TC), and Tibiotalar angle (TT) measurements were collected on preoperative and last follow up radiographs. The majority of patients underwent medial distal tibia hemiepiphysiodesis. Post-surgical AOFAS and SF36 scores were collected. Results: Preoperatively, no patient complained of instability, however, 9/16 ankles were painful and 14/16 were clinically in valgus. Patients underwent surgery at an age of 11.8 years (9.7-15). Radiographic and clinical follow up were 2.6 years (0.2-7.3) and 6 years (1.5-11.7), respectively. There were no significant differences between pre/postoperative M, TC, TT angles. Operative patients improved mean M (5.17 to 4.63 mm) and TT (8.71 to 4.54 degrees), neither angle reached normal values. TC (fibular length) was within normal limits (82.2 to 84.8). Questionnaires were obtained for 8/16 ankles, at a mean age of 19 years (13-25.1). The average AOFAS score was 66.7 out of 100. Patients scored 8.6/10 for alignment, 32/40 for pain, 25.6/50 for function. SF-36 scores were excellent. Conclusion: The improvement in M and TT was modest and their values remained outside the normal limits. TC angle was within normal limits but displayed an overall fibular shortening and thus, decreased lateral buttress with potential for talar shift. This was reflected in the mean functional and overall AOFAS score. However, our patients are functionally compensating as evidenced by SF36 scores. More studies are needed to optimize the management of MHE patients with ankle malalignment. Earlier valgus correction and possible addition of fibular lengthening to simultaneously address mortise widening may need to be considered to prevent early ankle arthritis.

Objective: To assess whether unhealthy behaviors moderated the relationship between allostatic load (AL) and future significant depressive symptoms (SDSs) among 1,789 older Latinos. Method: Longitudinal data included baseline AL, three unhealthy behaviors (UBs), and 2-year follow-up SDS. Multivariable logistic regression analyses, stratified by birthplace (U.S. vs. foreign born), modeled the effects of AL, UB count (range = 0-3), and their interaction on follow-up SDS. Results: Compared with U.S.-born, foreign-born participants engaged in fewer UBs (0.52 vs. 0.60 behaviors, p = .01) and had higher baseline SDS (31% vs. 20%, p < .001). Among foreign-born participants, the effect of AL on future SDS (adjusted odds ratios [aORs]; 95% confidence interval [CI]) significantly increased across UB counts of 0 to 3: 1.06 [0.83, 1.35], 1.46 [1.14, 1.87], 2.00 [1.18, 3.41], and 2.75 [1.18, 6.44], respectively. Discussion: Among foreign-born Latinos, these results were most pronounced for women and adults above age 80, which may represent higher risk groups requiring more intensive screening for depression.

Category: Ankle Arthritis Introduction/Purpose: Total ankle arthroplasty (TAA) has been shown to be an effective treatment for end stage ankle arthritis. Achieving normal anatomical alignment has been shown to be important in long term outcomes and revision rates. Recent data from the British NJR has shown that revision rates are higher in patients with pre-operative fixed equinus. Although there is literature about surgical techniques to deal with pre-operative equinus we are not aware of any papers presenting patient outcomes. We present patient reported outcomes for our cohort of patients with pre-operative fixed equinus compared to those able to achieve a plantigrade ankle. Methods: This is a single surgeon, retrospective cohort study of consecutive cases. A mobile bearing prosthesis was used (Mobility TAA system, DePuy, Raynham, Massachusetts, USA). Cases were identified from a locally held joint registry which routinely records PROMS data pre-operatively and at annual intervals post-operatively. Patients undergoing primary TAA between March 2006 and June 2014 were included, revision procedures along with those with inadequate PROMS data were excluded. PROMS scores used were FAOS (WOMAC Pain, Function and Stiffness), SF-36 scores and patient satisfaction. All pre-operative lateral weight bearing xrays were reviewed to screen for potential fixed equinus deformity (tibia-sole angle >90 degrees). Clinical records were then reviewed to confirm clinical diagnosis of fixed equinus deformity. Results: 259 cases were identified, 95 cases were excluded based on our criteria leaving 164 cases for analysis (mean follow up 61.6 months). 144 were classified as neutral and 20 as fixed equinus. The fixed equinus group were significantly younger (neutral 64.2 vs equinus 53.9, p=0.0002), there was no difference in BMI or length of follow up. There was no difference in baseline scores except WOMAC stiffness, with the fixed equinus group significantly worse (36.9 vs 25.6, p=0.0014). Final PROMS score, change from baseline and patient satisfaction was the same in all domains for both groups. There was no difference in revision rates. Conclusion: A pre-operative fixed equinus deformity does not negatively impact on clinical outcomes in patients undergoing TAA. We are not aware of any previous studies to compare results. As expected the equinus group showed higher levels of stiffness pre-operatively. Contrary to the British NJR dataset we did not find a difference in revision rates.

Background: Total ankle arthroplasty is a viable option for the treatment of end stage ankle arthritis. The purpose of this study is to report on the mid-term results with a cemented total ankle prosthesis, the Inbone™ II implant over a 5 year period. Methods: A retrospective, single-center chart and radiographic review of all patients with end stage ankle arthritis treated with Inbone™ II TAR) as the primary index procedure from 12/1/2012 to 3/1/2017. Clinical data were evaluated at 3 month, 6 month, 1 year and subsequent intervals for the study period. Preoperative diagnosis, pertinent patient demographics adjunctive procedures, implant associated complications, subsequent surgeries, and revisions were recorded. Results: 121 total ankles met our inclusion criteria. Patients had an INBONE™ II TAR implant placed with bone cement with a minimum of a 12 months follow up. Average age was 62.88 (range, 32-87) years, average body mass index was 32.74 (range, 21.8-56.04) kg/m2 and average follow up was 28.51(range, 12-69) months. Using the COFAS complication classification there were 14 minor, 11 moderate, and 5 major complications. 6/121 (5.0%) revisions which included: polyethylene exchange, device explant/fusion, and antibiotic spacer in situ. No complications over the course of this study ended in amputation. Conclusion: Total Ankle Arthroplasty utilizing the cemented INBONE™ II yielded good midterm results with regards to minor, moderate, and major complications. Rate of revision 6/121 (5.0%) was within the reported range with only 5 patients converted to fusion during the study period resulting in a 95% survivability at mid-term follow up. Levels of Evidence: Level IV: Retrospective case series
