RESUMO

Background: The incidence of primary total ankle arthroplasty (TAA) is rising, with a corresponding increase in revision surgeries. Despite this, research on risk factors for revision TAA following primary TAA remains limited. Radiographic soft tissue thickness has been explored as a potential predictor for outcomes in hip, knee, and shoulder arthroplasty, but its role in TAA has not been assessed. This study aimed to assess the predictive value of radiographic soft tissue thickness for identifying patients at risk of requiring revision surgery following primary TAA. Methods: A retrospective study was conducted on 323 patients who underwent primary TAA between 2003 and 2019. Radiographic measurements of soft tissue thickness were obtained from preoperative radiographs. Two novel radiographic measures of soft tissue thickness were developed and assessed (tibial tissue thickness and talus tissue thickness). Clinical variables including age, gender, body mass index (BMI), American Society of Anesthesiologists (ASA) classification, diabetes, smoking status, primary diagnosis, and implant type were recorded. Logistic regression analysis was used to assess the predictive value of soft tissue thickness and BMI for revision TAA. Results: The rate of revision surgery was 4.3% (14 of 323 patients). Patients requiring revision had significantly greater tibial tissue (3.54 vs 2.48 cm; P = .02) and talus tissue (2.79 vs 2.42 cm; P = .02) thickness compared with those not requiring revision. Both the tibial tissue thickness (odds ratio 1.16 [1.12-1.20]; P < .01) and the talus tissue thickness (odds ratio: 1.10 [1.05-1.15]; P < .01) measurements were significant predictors of revision TAA in multivariable logistic regression models. However, BMI was not a significant predictor of revision TAA. The two metrics demonstrated excellent interrater reliability. Conclusion: Greater soft tissue thickness was a better predictor of revision TAA compared with BMI. These findings suggest that radiographic soft tissue thickness may be a valuable tool for assessing the risk of the need for revision TAA following primary TAA. Further research is needed to validate and explore the potential impact on clinical practice. Level of Evidence: Level III, comparative study.

RESUMO

BACKGROUND: As total ankle arthroplasty (TAA) increases in popularity nationwide for the management of end-stage arthritis, it is essential to understand ways to mitigate the risk of infection. Diabetes increases the risk of infection due to compromised immunity and impaired wound-healing mechanisms. However, there is limited research on how diabetic management, inclusive of medications and glucose control, may impact infection risks post-TAA. This study aims to demonstrate the impact of diabetic management on the occurrence of periprosthetic joint infection (PJI) following TAA. METHODS: This was a retrospective study of patients who underwent a TAA at a single academic institution from March 2002 to May 2022. Patients with diabetes who developed an intraarticular infection following TAA were propensity score matched (1:3) to diabetic patients who did not. Data collection included demographics, implant types, diabetic medications, and preoperative hemoglobin A1c. PJI was diagnosed based on Musculoskeletal Infection Society (MSIS) criteria. Statistical analyses assessed differences in medication use, glucose control, and infection rates between groups. RESULTS: Of the 1863 patients who underwent TAA, 177 patients had a diagnosis of diabetes. The infection rate in patients with diabetes (2.8%) was higher than the total cohort rate (0.8%). Five patients with diabetes developed a PJI at an average of 2.2 months postoperatively. This cohort (n = 5) was compared to propensity score-matched controls (n = 15). There was no significant difference in diabetic medication use. Patients who developed PJI had higher rates of uncontrolled diabetes (60.0% vs. 6.7%) and average A1c levels (7.02% vs. 6.29%) compared to controls. CONCLUSION: Our findings suggest that the elevated risk of PJI observed in individuals with diabetes subsequent to TAA may be attributed not solely to the presence of diabetes, but to inadequate glycemic control. Effectively managing blood glucose levels is imperative for achieving favorable outcomes following TAA. LEVEL OF EVIDENCE: III.

RESUMO

BACKGROUND: The utilization of total ankle arthroplasty (TAA) for managing severe ankle osteoarthritis has become increasingly common, leading to a higher occurrence of revision TAA procedures because of failure of primary TAA. This study aims to examine the clinical results associated with revision TAA using the INBONE II system. Given the growing number of TAA revision procedures and a focus on motion-preserving salvage options, we evaluated our early experience with revision TAA. METHODS: A retrospective analysis was conducted on a group of 60 presumed noninfected patients who underwent revision TAA with the INBONE II system. Detailed information was collected on patient demographics, implant characteristics, concurrent procedures, and complications. The implant survival was estimated using Kaplan-Meier analysis. RESULTS: The study revealed high complication rates but generally fair clinical outcomes for revision TAA using the INBONE II system. Complications were observed in 22 patients (36.7%), including persistent pain (n = 6), nerve injury/impingement (n = 5), infection (n = 3), fracture (n = 3), implant failure (n = 3), impaired wound healing (n = 2), and osteolysis (n = 3). The 3-year survivorship rate from reoperation was 92.0% (82.7%-100.0%) whereas the 3-year survivorship rate from major complications was 90.4% (80.8%-100.0%). CONCLUSION: We report high complication rates but generally fair clinical results for revision TAA utilizing the INBONE II system.

RESUMO

BACKGROUND: Ankle arthritis differs from arthritis of the hip and knee in that 80% is posttraumatic and thus often occurs in a younger patient population. The literature supporting total ankle arthroplasty (TAA) in younger patients has increased over recent years and has bolstered the argument that in the short term, TAA in younger patients has successful outcomes that are comparable to older, lower-demand patients.The purpose of our study was to evaluate patient-reported outcomes (PROs) and implant survivorship at midterm after primary TAA in patients ≤ 50 years of age at the time of surgery. METHODS: A retrospective chart review was conducted of patients ≤ 50 years of age who underwent primary TAA at a single institution from 2000 to 2017. Patient demographics, outcome measures, and complications were recorded. All patients had a minimum clinical follow-up of 5 years. PRO measures were evaluated at preoperative, 1-year postoperative, and final follow-up visits. Paired t tests were performed to compare individual patient changes in PROs from preoperative. Implant survivorship was evaluated based on need for revision of either the tibial or talar component. The need for additional surgery related to the TAA was also evaluated. RESULTS: A total of 58 patients were included. The average age at the time of the index surgery was 43.3 years (range 22-50 years). All patients had a minimum follow-up of 5 years with a mean follow-up of 8.8 years. A total of 11 patients required additional surgery related to their TAA. Six patients (10.3%) required bone grafting of peri-implant cysts, 3 patients (5.2 %) required gutter debridement, and 1 patient underwent complete revision of metal components. Mean visual analog scale, 36-item Short Form Health Survey, Short Musculoskeletal Function Assessment, and American Orthopaedic Foot & Ankle Society hindfoot scores significantly improved from preoperative to 1-year postoperative and final postoperative follow-up. CONCLUSION: The patients aged ≤50 years treated with a TAA whom we have been able to observe for a minimum of 5 years showed generally maintained improvement in functional scores and thus far have had a relatively low rate of secondary surgeries.Level of Evidence:Level III, retrospective cohort study.

RESUMO

BACKGROUND: Although many patients with posttraumatic ankle arthritis are of a younger age, studies evaluating the impact of age on outcomes of primary total ankle arthroplasty (TAA) have revealed heterogenous results. The purpose of the present study was to determine the effect of age on complication rates and patient-reported outcomes after TAA. METHODS: We retrospectively reviewed the records of 1,115 patients who had undergone primary TAA. The patients were divided into 3 age cohorts: <55 years (n = 196), 55 to 70 years (n = 657), and >70 years (n = 262). Demographic characteristics, intraoperative variables, postoperative complications, and patient-reported outcome measures were compared among groups with use of univariable analyses. Competing-risk regression analysis with adjustment for patient and implant characteristics was performed to assess the risk of implant failure by age group. The mean duration of follow-up was 5.6 years. RESULTS: Compared with the patients who were 55 to 70 years of age and >70 years of age, those who were <55 years of age had the highest rates of any reoperation (19.9%, 11.7%, and 6.5% for the <55, 55 to 70, and >70-year age groups, respectively; p < 0.001), implant failure (5.6%, 2.9%, and 1.1% for the <55, 55 to 70, and >70-year age groups, respectively; p = 0.019), and polyethylene exchange (7.7%, 4.3%, and 2.3% for the <55, 55 to 70, and >70-year age groups, respectively; p = 0.021). Competing-risk regression revealed a decreased risk of implant failure for patients who were >70 of age compared with those who were <55 years of age (hazard ratio [HR], 0.21 [95% confidence interval (CI), 0.05 to 0.80]; p = 0.023) and for patients who were 55 to 70 years of age compared with those who were <55 years of age (HR, 0.35 [95% CI, 0.16 to 0.77]; p = 0.009). For all subscales of the Foot and Ankle Outcome Score (FAOS) measure except activities of daily living, patients who were <55 years of age reported the lowest (worst) mean preoperative and postoperative scores compared with those who were 55 to 70 years of age and >70 years of age (p ≤ 0.001). Patients who were <55 years of age had the highest mean numerical pain score at the time of the latest follow-up (23.6, 14.4, 12.9 for the <55, 55 to 70, and >70-year age groups, respectively; p < 0.001). CONCLUSIONS: Studies involving large sample sizes with intermediate to long-term follow-up are critical to reveal age-related impacts on outcomes after TAA. In the present study, which we believe to be the largest single-institution series to date evaluating the effect of age on outcomes after TAA, younger patients had higher rates of complications and implant failure and fared worse on patient-reported outcome measures. LEVEL OF EVIDENCE: Prognostic Level III . See Instructions for Authors for a complete description of levels of evidence.

RESUMO

BACKGROUND: Despite substantial increase in total ankle arthroplasty (TAA) nationwide, there are few studies comparing flat-cut vs chamfer-cut talar systems in TAA with regard to radiographic aseptic loosening rates of the implant. METHODS: This retrospective study included 189 Salto-Talaris TAA and 132 INBONE II primary TAA with a minimum 1-year follow-up. Patient characteristics were obtained including gender, age at surgery, body mass index (BMI), smoking status, primary diagnosis, surgical time, and the presence of diabetes. Radiographic evidence for aseptic loosening was assessed. Statistical analysis was performed for comparison in outcomes between Salto-Talaris and INBONE II. RESULTS: The mean age of the study population was 63.5 ± 9.8 years at surgery. Mean follow-up was 4.9 ± 3.0 years. Radiographic aseptic loosening of the tibial implant showed no significant difference between the 2 groups: Salto-Talaris, 18%, and INBONE II, 18.9% (P = .829). Aseptic loosening of the talar implant also showed no significant difference between the 2 groups: Salto-Talaris, 1.6%, and INBONE II, 1.5% (P = .959). No variables, including the implant type, were found to contribute to the aseptic loosening rate of either the tibia or talus. CONCLUSION: In our cohort, we observed no difference in radiographic implant aseptic loosening between Salto-Talaris and INBONE II systems. LEVEL OF EVIDENCE: Level IV, retrospective case series study.

RESUMO

BACKGROUND: Infection is a serious complication of primary total ankle arthroplasty (TAA) and can lead to implant failure and revision surgery. Various demographic, comorbidity, and surgical factors have been associated with an increased risk of infection. However, the evidence base remains limited, and further research is needed regarding infection in TAA. This study aims to analyze risk factors of infection and explore outcomes following infected TAA. METHODS: A retrospective cohort study was conducted using data from a single institution from 2002 to 2022. Patients who underwent primary TAA and had subsequent infection were identified through annual registry surveillance and matched using propensity score matching (PSM) based on various demographic, comorbidity, and surgical factors. Demographics were compared between the matched groups using Mann-Whitney U test and Fisher exact test. The outcomes following infection were identified and summarized using descriptive statistics. RESULTS: A total of 1863 patients who underwent primary TAA were identified, and 19 were diagnosed with an infection. The identifiable overall infection rate was 1.0%. After PSM, there were no significant differences in the difference in age, gender, BMI, and smoking status between the infected and control cohort. There was a statistically significant increase in the rate of diabetes in the infected cohort. The subsequent surgical intervention resulted in limb salvage in 18 (94.7%) cases. Out of the total number of cases, 2-stage revision to total ankle replacement was performed in 7 cases, whereas revision to arthrodesis and isolated polyethylene exchange were each carried out in 4 cases. One patient had to undergo amputation; however, at the time of the most recent follow-up, all patients were found to be free of infection. CONCLUSION: This study demonstrated high rates of a history of smoking and diabetes in the infected TAA cohort. The diabetes rate in the infected group was significantly higher than the noninfected controls. Two-stage revision to total ankle replacement was performed in 7 cases, and revision to arthrodesis and isolated polyethylene exchange were each carried out in 4 cases. Overall, a high rate of limb salvage was reported. LEVEL OF EVIDENCE: Level III, case-control study.

RESUMO

Background: Total ankle arthroplasty (TAA) provides a surgical alternative to tibiotalar arthrodesis when treating end-stage ankle arthritis. TAA preserves range of motion at the tibiotalar joint leading to improved postoperative function. Many patients who undergo TAA wish to maintain a high level of activity, including participation in low-impact sports such as golf. There are several studies in the total hip and total knee arthroplasty literature that have looked at the effect of total joint arthroplasty on golf handicap. We hypothesized that similar to hip and knee arthroplasty research, TAA is likely to result in a postoperative increase in golf handicap. Methods: After obtaining institutional review board approval, we retrospectively identified 60 patients (from 140 consecutive TAAs performed between August 2016 and February 2017) who had undergone TAA, played golf pre- and postoperatively, and had at least 1 year of postoperative follow-up. The average postoperative follow-up for the cohort was 28.1 months. Variables including preoperative and postoperative golf handicaps, swing laterality, age, gender, surgical laterality, implant used, and operating surgeon were recorded. Results: The average preoperative and postoperative handicaps were 19.7 and 17.9, respectively, which did not represent a statistically significant difference (P = .07). Patients who played 3 or more rounds per week had better preoperative and postoperative handicaps compared to patients who played 2 rounds or less; however, the change in their handicap following TAA and the number of rounds played per week was not affected. There was no association between the change in handicap and the follow-up period, handedness of golf shot, surgical laterality, implant used, or the operating surgeon. Conclusion: Our findings showed that golf handicap was not negatively affected following TAA in this series. Level of Evidence: Level IV, case series.

RESUMO

BACKGROUND: There is limited data evaluating the effect of obesity on outcomes following total ankle arthroplasty (TAA), especially in adequate sample sizes to detect impacts on patient-reported outcomes (PROs). The purpose of this study was to assess the effect of obesity on complication rates and PROs. METHODS: This was a single-institution, retrospective study of 1093 primary TAA performed between 2001 and 2020. Minimum follow-up was 2 years. Patients were stratified by body mass index (BMI) into control (BMI = 18.5-29.9; n = 615), obesity class I (BMI = 30.0-34.9; n = 285), and obesity class II (BMI > 35.0; n = 193) groups. Patient information, intraoperative variables, postoperative complications, and PRO measures were compared between groups using univariable statistics. Multivariable Cox regression was performed to assess risk for implant failure. Mean follow-up was 5.6 years (SD: 3.1). RESULTS: Compared to control and class I, class II patients had the lowest mean age (P = .001), highest mean ASA score (P < .001), and greatest proportion of female sex (P < .001) and Black/African American race (P = .005). There were no statistically significant differences in postoperative complications (infection, implant failure, or impingement) across the BMI classes (P > .05).Preoperatively, class II had lower (worse) mean scores for Foot and Ankle Outcome Score pain and ADL subscales than controls (post hoc pairwise P < .001 for both). At final follow-up, both class II and class I had lower (worse) mean Short Musculoskeletal Function Assessment (post hoc pairwise P < .001 and P = .030, respectively) and 36-Item Short Form Health Survey scores (post hoc pairwise P < .001 and P = .005, respectively) than controls. CONCLUSION: At midterm follow-up, obesity was not associated with increased rates of complications after TAA. Patients with obesity reported worse musculoskeletal function and overall quality of life after TAA but there was no differential improvement in PROs across BMI classes. To our knowledge, this is the largest single-institution study to date examining the effect of obesity on outcomes after primary TAA. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

RESUMO

Background: The Malerba calcaneal Z-osteotomy is an operative procedure to treat the hindfoot varus component of adult cavovarus deformity. Basic science studies support the corrective ability of this osteotomy. However, there have been no published midterm clinical and radiographic results. The purpose of this article is to describe the radiographic and clinical improvement in a series of patients treated with this osteotomy. Methods: A retrospective chart review identified 14 feet in 12 patients from January 2013 to August 2018 who met minimal follow-up criteria. Preoperative visual analog scale (VAS) scores, Foot Function Index (FFI) scores, and American Orthopaedic Foot & Ankle Society (AOFAS) scores were compared with postoperative scores. Preoperative Meary angle, calcaneal pitch, and hindfoot alignment were also compared with postoperative measurements. Complications and radiographic union were recorded. Results: At a mean of 80 months, VAS, FFI, and AOFAS scores improved from 7.86 to 1.64, 57.78% to 18.11%, and 39.57 to 80.71, respectively (all P < .001). At a mean of 15 months, Meary angle, calcaneal pitch, and hindfoot alignment improved from 11.14 to 6.64 degrees (P < .001), 30.93 to 27.43 degrees (P = .005), and 19.83 degrees varus to 8.50 degrees varus (P < .001). There was 1 nonunion and 1 postoperative sural nerve neuralgia, but both patients ultimately did well clinically. There were no instances of postoperative tarsal tunnel syndrome. All patients stated that they would have the procedure done again. Conclusion: The calcaneal Z-osteotomy is an effective method to treat adult hindfoot cavovarus deformity. All patients had good clinical outcomes with minimal complications. Level of Evidence: Level IV, case series.

RESUMO

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.

RESUMO

BACKGROUND: End-stage ankle arthritis is a debilitating condition often necessitating total ankle replacement (TAR). Tendo-Achilles lengthening (TAL) and gastrocnemius recession (GR) are commonly performed with TAR to improve ankle dorsiflexion (DF). No studies to date have radiographically analyzed tibiopedal motion to guide surgical management. The purpose of this study is to determine the effect of a TAL or GR during TAR on radiographic tibiopedal range of motion (ROM). METHODS: A retrospective review of a prospectively maintained database was conducted followed by a propensity score-matched analysis of 110 patients who underwent TAL (n = 26), GR (n = 29), or no lengthening procedure (n = 55) with TAR. Minimum of 1-year ROM radiographic follow-up was required. Exclusion criteria included (1) calcaneal osteotomies, (2) simultaneous or previous hindfoot or midfoot arthrodesis, (3) prior ankle arthrodesis, or (4) revision TAR. Demographic data were extracted from the TAR database. Radiographic assessment included tibiopedal dorsiflexion (DF) and plantarflexion (PF). RESULTS: DF improved by 2.8 degrees (P = .0286) and by 6.0 degrees (P < .0001) in the TAL and GR cohorts, respectively, with no difference in the control group (+0.7 degrees, P = .3764). PF was decreased by 4.5 degrees (P = .0152) and by 7.2 degrees (P = .0002) in the TAL and GR cohorts, respectively, with no difference in the control group (-0.2 degrees, P = .8546). Minimal differences were observed for total arc of motion for all 3 groups (control 0.5 degrees, GR -1.2 degrees, TAL -1.7 degrees), all of which were nonsignificant (all P > .05). There was no between-group difference in the change in overall arc of motion between the groups (P = .3599). GR resulted in a greater increase in DF (6.0 vs 2.8 degrees; P = .1074), with a reciprocal greater decrease in PF (7.2 vs 4.5 degrees; P = .2416) compared with the TAL cohort. CONCLUSION: Both TAL and GR increased postoperative DF; however, this was accompanied by a reciprocal loss in PF. Minimal differences were observed for total arc of motion. Patients should be counseled that concomitant procedures performed to increase DF will do so at the expense of PF. LEVEL OF EVIDENCE: Level III, retrospective review of prospectively collected data.

RESUMO

BACKGROUND: The risk-benefit profiles of simultaneous total ankle arthroplasty (TAA) compared with sequential TAA continue to be debated. There are limited case series reporting outcomes after bilateral TAA, with no previous comparison of simultaneous TAA with sequential TAA. Patients with bilateral pathology represent a unique population with an overall more debilitating condition. Thus, we aimed to compare bilateral simultaneous and sequential TAAs, including perioperative complications and patient-reported outcome measures. METHODS: We performed a comparative cohort study of patients who underwent primary bilateral TAA, performed in a simultaneous or sequential fashion, from 2007 to 2019 at a single academic center. Data on patient demographic characteristics, comorbidities, perioperative complications, reoperations, and implant failures were collected. Patient-reported outcome measures included preoperative and postoperative visual analog scale (VAS) scores for pain, Short Form-36 Health Survey (SF-36) scores, and Short Musculoskeletal Function Assessment (SMFA) scores. RESULTS: A total of 50 patients (100 ankles) were included, with 25 patients (50 ankles) each in the bilateral simultaneous and sequential cohorts. The mean follow-up was 52.2 ± 27.3 months (range, 24 to 109 months). The mean time between sequential TAAs was 17.5 ± 20.1 months (range, 3 to 74 months). The mean patient age was 64.3 ± 10.6 years (range, 21 to 76 years), and 32 (64.0%) were men. The majority of patients (28 patients [56.0%]) had primary osteoarthritis. Both cohorts had equivalent preoperative patient-reported outcome measures and experienced improvements in all measures, which were maintained at the final follow-up with no significant between-group differences (all p > 0.05). There were no differences between the simultaneous TAA group and the sequential TAA group in perioperative complication rates (22.0% compared with 24.0%; p = 0.7788), reoperations (12.0% compared with 10.0%; p = 0.7354), 5-year reoperation-free survival (88.0% compared with 90.0%; p = 0.4612), or failure-free survival (100%). One patient in the simultaneous TAA cohort required metal component revision at 8 years postoperatively. CONCLUSIONS: The patient-reported outcome measures, complications, and prosthesis survival of patients who underwent bilateral simultaneous TAA were comparable with those of patients who underwent bilateral sequential TAA. We advocate that simultaneous bilateral TAA is a safe and effective method for the treatment of bilateral end-stage ankle osteoarthritis. LEVEL OF EVIDENCE: Therapeutic Level III .

RESUMO

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. CONCLUSION: 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. LEVEL OF EVIDENCE: Level III, therapeutic, retrospective comparative series.

RESUMO

Currently, total ankle replacement (TAR) is an alternative to arthrodesis in selected patients, with the anterior approach being the most widely used to carry it out. Regardless of the type of implant used, the pins for bone resection guides, chisels, and the saw for distal tibial resection can endanger the neurovascular and tendon structures that lie in intimate proximity to the posterior aspect of the ankle. Additionally, there is a documented complication rate of up to 15.3% in such surgery. We have implemented a protective posteromedial approach that complements the anterior approach to reduce this risk of intraoperative iatrogenic injury. Using this method we introduce a protective instrument that separates the posterior anatomical structures from the posterior cortex of the tibia. This article describes the surgical technique used to carry out TAR through an anterior approach in a safer way, without increasing complications or the duration of real-time surgery.

RESUMO

Background. Ankle arthritis is a major cause of disability. Orthopaedic literature suggests improvement in health-related quality of life (HRQOL) after total ankle arthroplasty (TAA). This has not been compared with improvements observed in successful orthopaedic and nonorthopaedic procedures, including anterior cervical discectomy/fusion (ACDF), total knee arthroplasty (TKA), coronary artery bypass grafting (CABG), and orthotopic liver transplant (OLT). We hypothesize that the effects after TAA are comparable to several successful surgical procedures. Methods. 500 consecutive TAA patients were included and grouped with 2 other large series. Short Form-36 (SF36) were collected at standardized intervals. A systematic literature review identified studies comparing preoperative and postoperative SF36 physical (PCS) and mental component summary (MCS) scores. Using meta-analyses, we pooled the data for each procedure to compare with the TAA group. Results. Patients in all cohorts had preoperative SF36 MCS and PCS scores that were significantly lower than that in the general population. Improvements in HRQOL after TAA were not statistically different from improvements reported in PCS and MCS after ACDF, TKA, and OLT. However, improvement in PCS after TAA was better than that observed after CABG. Conclusions. Disability with ankle arthritis is severe. Disability associated with cervical disc disease, knee arthrosis, coronary artery disease, and liver failure is also severe, with surgical intervention providing major improvements in HRQOL postoperatively. The improvement in HRQOL after TAA did not differ statistically from ACDF, TKA, CABG, and OLT. Our investigation suggests that the HRQOL benefits of TAA meet benchmarks set by some of modern medicine's best.Levels of Evidence: Level III: Systematic review.

RESUMO

Background. Total ankle arthroplasty (TAA) use has increased with newer generation implants. Current reports in the literature regarding complications use data extracted from high-volume centers. The types of complications experienced by lower-volume centers may not be reflected in these reports. The purpose of this study was to determine a comprehensive TAA adverse event profile from a mandatory-reporting regulatory database. Methods. The US Food and Drug Administration's Manufacturer and User Facility Device Experience (MAUDE) database was reviewed from 2015 to 2018 to determine reported adverse events for approved implants. Results. Among 408 unique TAA device failures, the most common modes of failure were component loosening (17.9%), intraoperative guide or jig error (15.4%), infection (13.7%), and cyst formation (12.7%). In addition, the percentage distribution of adverse event failure types differed among implants. Conclusion. The MAUDE database is a publicly available method that requires mandatory reporting of approved device adverse events. Using this report, we found general agreement in types of complications reported in the literature, although there were some differences, as well as differences between implants. These data may more accurately reflect a comprehensive profile of TAA complications as data were taken from a database of all device users rather than only high-volume centers.Levels of Evidence: NA.

RESUMO

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.

RESUMO

BACKGROUND: Characteristics of responders, or those who achieve a clinical improvement above the level of a minimal clinically important difference, have not been defined for total ankle arthroplasty (TAA). The purpose of this study was to determine patient characteristics that distinguish possible responders from possible nonresponders after TAA using criteria established for other arthroplasty surgeries. METHODS: Patients undergoing TAA who were enrolled into a prospective study at a single academic center evaluating patient-reported outcomes were included. Patients were characterized as possible responders if the relative or absolute improvement in their 2-year follow-up Short Musculoskeletal Function Assessment (SMFA) function score was at least 50% or 20, respectively, compared with their preoperative score, consistent with Outcome Measures in Rheumatoid Arthritis Clinical Trials and the Osteoarthritis Research Society International (OMERACT-OARSI) responder criteria. Patient factors were then associated with possible responder or nonresponder status and a multivariable analysis was performed. A total of 491 patients with complete data and 2-year follow-up were included in this study. RESULTS: Multivariable analysis demonstrated that a higher baseline 36-Item Short-Form Survey (SF-36) mental component summary (MCS) score (OR [95% CI], 1.02 [1.01, 1.04]; P = .003), indicating better mental health, was associated with being a possible responder to TAA. The presence of rheumatic disease (OR [95% CI], 0.38 [0.22, 0.67]; P = .001) was a significant predictor of being a possible nonresponder. CONCLUSION: Our data reveal that a higher baseline SF-36 MCS score was associated with increased improvement in SMFA function scores, while rheumatic disease was associated with worse improvement in SMFA function scores after TAA. Patients with rheumatic disease or poor mental health may not achieve as favorable results after TAA and should be counseled appropriately. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

RESUMO

BACKGROUND: Neutral ankle alignment along with medial and lateral support are paramount to the success of total ankle replacement (TAR). Fibula, intra-articular medial malleolus, and supramalleolar tibia osteotomies have been described to achieve these goals; however, the literature is scant with outcomes and union rates of these osteotomies performed concomitant to TAR. The purpose of this study was to describe our results. METHODS: A retrospective review was performed to identify patients who had a concomitant tibia, fibula, or combined tibia and fibula osteotomy at the same time as TAR. Routine radiographs were used to assess osteotomy union rates and changes in alignment. Outcomes questionnaires were evaluated preoperatively and at most recent follow-up. Twenty-six patients comprising 4% of the total TAR cohort were identified with a mean follow-up of 3.9 years. RESULTS: There were 12 combined tibia and fibula osteotomies, 9 isolated tibia osteotomies, and 5 isolated fibula osteotomies. The union rate for these osteotomies was 92%, 100%, and 100%, respectively. Mean coronal alignment improved from 15.2 to 2.1 degrees (P < .001). There was significant improvement in patient-reported outcome scores, including Short Form-36, Short Musculoskeletal Function Assessment, and visual analog scale pain. There was 1 failure in the study. CONCLUSION: These data demonstrate successful use of tibia, fibula, or combined tibia and fibula osteotomies at the same time as TAR in order to gain neutral ankle alignment. The overall union rate was 96% with significant improvement in alignment, pain, and patient-reported outcomes. We believe concomitant osteotomies can be considered a successful adjunctive procedure to TAR. LEVEL OF EVIDENCE: Level III, retrospective comparative series.
