Category: Ankle Arthritis; Ankle; Other Introduction/Purpose: The utilization of total ankle replacement (TAR) for end-stage ankle osteoarthritis continues to increase in the United States. From 2011-2012, 47.5% of all TAR were covered by Medicare insurance, which represents a large insurance market share for inpatient ankle surgeries. However, there is a growing trend in orthopedics toward performing outpatient surgery. There have been studies that demonstrate the cost benefits and safety of outpatient TAR surgery. However, previous cost studies involve a single implant, small sample size, and lack clinical outcomes. Thus, we aim to compare the costs and clinical outcomes associated with TAR in the outpatient versus inpatient settings. Methods: We performed a retrospective study on 178 consecutive patients undergoing primary inpatient versus short-stay designation TAR during the 2016 and 2017 fiscal years. Patient demographics, concomitant procedures, perioperative complications, patient reported outcomes, and perioperative costs were collected. Results: The mean age of our cohort was 62.5 yo. The implant types were: Infinity (39.3%), Salto (38.2%), INBONE (15.2%), Vantage (7.3%), and STAR (3.4%). 47.8% of patients were covered under managed care and 42.1% under Medicare. There were no significant differences in medical comorbidities (p > 0.05) or concomitant surgeries (p=0.4574) between inpatient and outpatient groups. There was no difference in complications between inpatient and outpatient groups (p= 0.9652). Inpatients had a greater improvement in their SMFA function score compared to outpatients (p=0.0442). Both inpatient and outpatient cohorts significantly improved in all other reported patient reported outcomes at final follow-up (<0.0001) without a difference between groups (p >0.05). The total direct cost was higher for the inpatient group ($15,340.1) versus outpatient group ($13,002.6) (p<0.0001). Conclusion: While inpatient designation TAR were more comorbid, short-stay designation TAR were associated with a 15.5% reduction in perioperative costs, comparable complication rates, and similar final postoperative patient reported outcome scores compared to inpatient TAR.

Background: We aimed to perform an economic analysis and compare the clinical outcomes between inpatient and short-stay designation total ankle replacement (TAR). Methods: We performed a retrospective study on 178 consecutive patients undergoing primary inpatient versus short-stay designation TAR during the 2016 and 2017 fiscal years. Patient demographics, concomitant procedures, perioperative complications, patient-reported outcomes, and perioperative costs were collected. Results: The mean age of our cohort was 62.5 ± 9.6 years (range, 30-88 years), with a significant difference in age (64.1 vs 58.5 years) ( P = .005) and Charlson Comorbidity Index (3.3 ± 1.9 vs 2.3 ± 1.4; P = .002) for the inpatient and short-stay designation groups, respectively. At a mean follow-up of 29.6 ± 11.8 months (range, 12-52.3 months), there was no difference in complications between groups ( P = .97). The inpatient designation TAR group had a worse baseline Short Musculoskeletal Functional Assessment (SMFA) function score (76.1; 95% CI, 70.5-81.6) than the short-stay designation TAR group (63.9; 95% CI, 52.5-75.3) while achieving similar final postoperative SMFA function scores for the inpatient (55.2; 95% CI, 51.1-59.2) and short-stay (56.2; 95% CI, 48.2-64.2) designation TAR groups ( P > .05). However, the inpatient designation TAR group showed a significantly greater mean improvement in SMFA function score (20.9; 95% CI, 19.4-22.4) compared with the short-stay designation TAR group (7.7; 95% CI, 3.7-11.1) ( P = .0442). The total direct cost was significantly higher for the inpatient designation group ($15 340) than the short-stay designation group ($13 002) ( P < .001). Conclusion: While inpatient designation TARs were more comorbid, short-stay designation TARs were associated with a 15.5% reduction in perioperative costs, comparable complication rates, and similar final postoperative patient-reported outcome scores compared with inpatient TARs. Level of Evidence: Level III, retrospective comparative study.

The purpose of this study was to compare complication rates after total ankle replacement in 2 groups of patients based on polyethylene insert size. The total cohort was divided into 2 groups based on insert size. Group 1 included patients with polyethylene insert size less than 10 mm in thickness. Group 2 included patients with polyethylene insert sizes 10 mm and larger. Available charts were reviewed for patients who underwent primary total ankle arthroplasty by one surgeon. Patient demographics, polyethylene insert size, implant used, concomitant procedures, postoperative complications, and patient-reported outcome scores were recorded. One hundred patients were available for follow-up and were included in this study, which ranged from March 2012 to July 2017. The average follow-up was 31.3 months (range = 10-60 months). Forty-eight females and 52 males were included in this study. There were a total of 63 patients in group 1 and 47 patients in group 2. The total complication rate for patients in group 1 was 11.1% (7/63), and in group 2 it was 16.2% (6/32). There was no statistical significance in complication rates when comparing the 2 groups (P = 0.5427). All patients underwent at least one concomitant procedure at the time of initial ankle replacement. Our findings show that total ankle replacement complication rates are equal when comparing large polyethylene inserts commonly utilized to correct deformities, versus small polyethylene inserts commonly utilized in primary resurfacing. Levels of Evidence: Level IV, Retrospective comparative study

Background: The purpose of this study was to report on the radiographic outcomes, clinical outcomes, and implant survivorship following extramedullary-referenced (EMr) vs intramedullary-referenced (IMr) total ankle replacement (TAR). Methods: From May 2007 to February 2018, a consecutive series of patients with end-stage tibiotalar osteoarthritis undergoing TAR was enrolled in this study. Analyses were performed comparing IMr vs EMr components for patient-reported outcomes data, pre- and postoperative radiographic ankle alignment, concomitant procedures, and complications. Kaplan-Meier survivorship analyses served to determine implant reoperation and revision surgery. A total of 340 TARs were included with 105 IMr TAR and 235 EMr TAR. The mean follow-up was 5.3 years (±2.5, range 2-12). Results: The absolute value for preoperative coronal alignment was significantly greater for IMr compared to EMr TAR (13.0 vs 6.4 degrees; P < .0001), but both groups achieved near neutral alignment postoperatively (1.4 vs 1.5 degrees; P = .6655). The odds of having a concomitant procedure was 2.7 times higher in patients with an IMr TAR (OR 2.7, CI 1.7-4.4; P < .0001). There were similar improvements in patient-reported outcome scores at 1 year and final follow-up (all P > .05). The 5-year implant survivorship was 98.6% for IMr vs 97.5% for EMr at final follow-up. Conclusion: The IMr and EMr TAR components had comparable postoperative alignment, patient-reported outcome scores, and complications. The 5-year implant survivorship was similar between the IMr and EMr groups. Level of Evidence: Level III, retrospective comparative study.

Category: Ankle; Ankle Arthritis; Diabetes; Midfoot/Forefoot Introduction/Purpose: The indications for Total Ankle Replacement (TAR) in patients with Type II Diabetes mellitus is poorly defined and there is paucity of literature reporting clinical, radiological and patient reported outcomes for TAR in this patient group. We aimed to explore the ideal pre-operative criteria for TAR in patients with Type II DM based on results from our center. Methods: We studied the x-rays, clinical findings and patient reported outcomes of surgery at pre-op and 5 years for patients who underwent a total ankle replacement at our center between 2006 and 2014 who had Type II DM. This was a retrospective study. The above findings were also compared between patients who had Type II DM vs. who were not diabetic. Pre-operative screening for diabetic patients included Hb1Ac levels, clinical reporting of swelling, warmth, erythema findings, neurovascular status including proprioception, vibration and neuro filament tests. Statistical analysis of WOMAC and SF-36 scores and differences between diabetic and non-diabetic patients were calculated using General Linear Model - repeated measures ANOVA. Patient satisfaction was analyzed using chi-square test. Rates of superficial and deep infection as well as revision were recorded. Results: Of 230 patients, 9 (3.9%) were diabetic. Pre-op radiographic analysis showed features confining to OA; x-ray, CT scan showed no signs of bone debris, fragmentation per articular fractures. Talus was not translated, no evidence of OA in Subtalar or Talonavicular joint. At 5 years, there was no implant subsidence, loosening, migration or peri-prosthetic cysts; hind and midfoot joints had no features of diabetic arthropathy/collapse. Comparing outcomes to Non-diabetic TAR patients, WOMAC & SF-36 scores showed significant (p<0.05) improvement and no significant difference between groups from pre-op to 5 years. In the diabetic group there was 1 superficial infection (11%) 1 deep infection that required revision (11%) compared to 30 superficial infections (13.6%), 1 deep infection (0.5%) and 12 revisions (5.4%) in the non-diabetic group. Conclusion: Painful end stage OA in Type II DM can be treated by TAR, taking into consideration the inclusion and exclusion criteria that we have used in our series.

Background: The purpose of this study was to evaluate gender differences in patient outcomes and complications following total ankle replacement (TAR). Methods: Consecutive patients who underwent primary TAR from July 2007 through May 2016 were prospectively followed and retrospectively reviewed. Demographic, operative, patient-reported outcomes (PROs), and complication data were collected and analyzed. PROs included the visual analog scale (VAS), 36-Item Short-Form Health Survey (SF-36), American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot scale, and Short Musculoskeletal Function Assessment (SMFA). A total of 475 patients were evaluated, including 248 males (52.2%) and 227 females (47.8%) with an average of 56.8 months follow-up. Results: Women were more likely to have inflammatory arthritis (13.7% vs 2.8%; P < .01) and significantly worse preoperative SF-36 total, SF-36 mental health component, AOFAS total, AOFAS pain, SMFA function, and SMFA bother scores (all P < .05). Both genders demonstrated significant improvement in PROs at 1, 2, and 5 years. The magnitude of improvement was similar between genders for all PROs (all P < .05) with the exception of SF-36 physical function, which was greater in men. Females underwent more nonrevision reoperations (32.2% vs 22.6%; P = .0191), but there was no significant difference in failure rates (male 7.3% vs female 3.5%; P = .07). The reoperation and failure rates at 2 years postoperation were 10.1% and 1.6% for men and 18.5% and 0.9% for women, respectively. Conclusions: Women undergoing TAR were more likely to have worse preoperative PROs and higher rates of nonrevision reoperations, which remains true when controlling for their increased incidence of inflammatory arthritis. However, women reported similar improvements in PROs and had similar prosthetic survival rates as men. Increased understanding of these disparities, combined with gender-based interventions, may further advance patient outcomes.

Category: Other Introduction/Purpose: Each year approximately 30-40% of people over the age of 65 fall. Approximately one half of these falls result in an injury with the estimated annual direct medical costs of $30 billion. Pain, mobility issues, neuropathy and post-operative weight bearing limitations make foot and ankle patients particularly vulnerable to falls. Current approaches to determine at risk patients are cumbersome and time consuming requiring performance testing and “hands on” clinical assessment. The efficiency of obtaining PRO, such as PROMIS, in the clinical arena has been well documented. The purpose of this study is determine if patient reported outcomes (PROMIS) can identify orthopaedic and specifically foot and ankle patients at risk to fall. Methods: Prospective patient reported outcomes (PROMIS CAT physical function, pain interference and depression and CMS fall risk assessment questions) and patient demographics were collected for all patients at each clinic visit from an academic orthopaedic multi-specialty practice between January 2015 and November 2017. Standardized yes/no validated self-reported fall risk questions include: “Have you fallen in the last year?” and “Do you feel you are at risk of falling?” Histograms, t-tests, confidence intervals and effect size were used to determine the fall risk “YES” patients were different than the “NO” for ALL orthopaedic patients and specifically foot and ankle patients. Logistic Regression was used to determine if age, gender, height, weight, and PROMIS scales predicted self-reported falls risk. Results: 94,761 orthopaedic patients comprising 315,273 visits (44% male, mean age 53.7+/-17 years) and 13,720 foot/ankle patients comprising 33,480 visits (37% male, mean age 52.7+/-16.1 years) had complete data for analysis. Table 1 provides the means/SD/p-values/effect sizes for patient self-identifying at risk to fall stratified by PROMIS PF/ PI/Dep t-scores. Although all PROMIS scores demonstrated significant impairment between patients at risk designation (yes/no), PROMIS PF had the largest effect size for ALL Ortho and FOOT AND ANKLE patients (0.8 and 0.7 respectively). Patients who are at risk to fall have PROMIS PF t-scores >1.5 lower than the United States normative population while the patients not at risk are less <1 SD. In the adjusted regression models gender and PROMIS PF had the largest coefficients. Conclusion: Falls are a major threat to quality of life and independence yet prevention/treatment strategies are difficult to implement across a health system. There is also a tremendous societal cost with orthopaedic surgeons often the recipient of these debilitated patients. PROMIS assessments are part of the AOFAS OFAR initiative to track patient recovery with treatment and can additional be used to fulfill a quality indicator requirement by CMS. This study demonstrates these assessments (PROMIS threshold values) can also be linked to self-report falls risk (yes/no) and may identify patients at risk with no face to face time required from the provider.

Background: Total ankle replacement (TAR) and ankle fusion are effective treatments for end-stage ankle arthritis. Comparative studies elucidate differences in treatment outcomes; however, the literature lacks evidence demonstrating what outcomes are important to patients. The purpose of this study was to investigate patients’ experiences of living with both a TAR and ankle fusion. Methods: This research study used qualitative description. Individuals were selected from a cohort of patients with TAR and/or ankle fusion (n = 1254). Eligible patients were English speaking with a TAR and contralateral ankle fusion, and a minimum of 1 year since their most recent ankle reconstruction. Surgeries were performed by a single experienced surgeon, and semistructured interviews were conducted by a single researcher in a private hospital setting or by telephone. Ankle Osteoarthritis Scale (AOS) scores, radiographs, and ancillary surgical procedures were collected to characterize patients. Themes were derived through qualitative data analysis. Results: Ten adults (8 men, 2 women), ages 59 to 90 years, were included. Average AOS pain and disability scores were similar for both surgeries for most patients. Participants discussed perceptions of each reconstructed ankle. Ankle fusions were considered stable and strong, but also stiff and compromising balance. TARs were considered flexible and more like a “normal ankle,” though patients expressed concerns about their TAR “turning” on uneven ground. Individuals applied this knowledge to facilitate movement, particularly during a first step and transitioning between positions. They described the need for careful foot placement and attention to the environment to avoid potential challenges. Conclusion: This study provides insight into the experiences of individuals living with a TAR and ankle fusion. In this unusual but limited group of patients, we found that each ankle reconstruction was generally perceived to have different characteristics, advantages, and disadvantages. Most participants articulated a preference for their TAR. These findings can help clinicians better counsel patients on expectations after TAR and ankle fusion, and improve patient-reported outcome measures by better capturing meaningful outcomes for patients. Level of Evidence: Level IV, case series.
