Category: Ankle Arthritis Introduction/Purpose: There is much interest in the surgical treatment of end-stage ankle arthritis. Our team has previously reported comparisons between ankle fusion and replacement outcomes for 321 ankles at 5.5 years from a prospective cohort. This research extends the observational period for another six years, ending in 2013. Our primary hypothesis is that patient-reported clinical outcomes for ankle fusion and replacements would be similar at last follow up. Methods: Patients in the Canadian Orthopaedic Foot and Ankle Society (COFAS) Prospective Ankle Reconstructive Database were treated with total ankle replacement (involving Agilty, Star, Mobilty, Hintegra, or Inbone) or fusion (open or arthroscopic). Patient characteristics collected included demographics, comorbidities, smoking status and body mass index. Patient-reported outcomes (PROs) completed by patients were the Ankle Osteoarthritis Scale (AOS) and Short Form-36 (SF-36). Pre-operative and most recent patient data, with at least four years follow-up, were analyzed. Sensitivity analyses excluded ankles that had undergone revision. A linear mixed-effects regression model compared scores between total ankle replacement and fusion groups, adjusting for patient characteristics, baseline data and surgeon. Results: The sample included 844 ankles (556 ankle replacements and 284 arthrodesis). The mean follow up period was 8.0 years (standard deviation 3.1 years), with minimum and maximum of 4 and 14 years, respectively. Patients treated with arthrodesis were younger, more likely to be diabetic and smokers, and somewhat less likely to have inflammatory arthritis. Overall, 19.4% of ankle fusion and 30.8% of ankle replacements underwent all-cause re-operation. The mean AOS total score improved from 58.6 points pre-operatively to 31.4 post-operatively (delta 27.2), and from 57.0 to 26.9 points (delta 30.1) in the ankle replacement group. Differences in the change in AOS and SF-36 scores between the arthrodesis and ankle replacement groups were minimal after adjustment for baseline characteristics and surgeon. Conclusion: Clinical outcomes of total ankle replacement and ankle arthrodesis were comparable in a diverse cohort of patients whose follow up period ranged between 4 and 14 years post-operatively.

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.

Replacement Design

Recently, the progress in techniques and in projecting new prosthetic designs has allowed increasing indications for total ankle replacement (TAR) as treatment for ankle osteoarthritis. This retrospective work comprehended 39 subjects aged between 47 and 79 years old. The patients, observed for at least 12 months (mean follow up of 18.2 ± 4.1 months), have been evaluated according to clinical and radiological parameters, both pre- and post-operatively. The AOFAS and VAS score significantly improved, respectively, from 46.2 ± 4.8 to 93.9 ± 4.1 and from 7.1 ± 1.1 to 0.7 ± 0.5 (p value < 0.05). At the final evaluation, the mean plantarflexion passed from 12.2° ± 2.3° to 18.1° ± 2.4° (p value < 0.05) and dorsiflexion from a pre-operative mean value of 8.7° ± 4.1° to 21.7° ± 5.4° post-operatively (p value < 0.05). This study found that this new total ankle replacement design is a safe and effective procedure for patients effected by end-stage ankle osteoarthritis. Improvements have been demonstrated in terms of range of motion, radiographic parameters and patient-reported outcomes. However, further studies are needed to assess the long-term performance of these prostheses.

Background: Outcomes of total ankle replacement for the treatment of end-stage ankle arthritis continue to improve. Debate continues whether a mobile-bearing total ankle replacement (MB-TAR) or a fixed-bearing total ankle replacement (FB-TAR) is superior, with successful outcomes reported long term for MB-TAR and at intermediate- to long-term follow-up for newer generation FB-TAR. Although comparisons between the 2 total ankle designs have been reported, to our knowledge, no investigation has compared the 2 designs with a high level of evidence. This prospective, randomized controlled trial conducted at a single institution compares patient satisfaction, functional outcomes, and radiographic results of the mobile-bearing STAR and the fixed-bearing Salto-Talaris in the treatment of end-stage ankle arthritis. Methods: Between November 2011 and November 2014, adult patients with end-stage ankle osteoarthritis failing nonoperative treatment were introduced to the study. With informed consent, 100 patients (31 male and 69 female, average age 65 years, range 35-85 years) were enrolled; a demographic comparison between the 2 cohorts was similar. Exclusion criteria included inflammatory arthropathy, neuropathy, weight exceeding 250 pounds, radiographic coronal plane deformity greater than 15 degrees, or extensive talar dome wear pattern (“flat-top talus”). Prospective patient-reported outcomes, physical examination, and standardized weightbearing ankle radiographs were obtained preoperatively, at 6 and 12 months postoperatively, and then at yearly intervals. Data collection included visual analog pain score, Short Form 36, Foot and Ankle Disability Index, Short Musculoskeletal Functional Assessment, and American Orthopaedic Foot & Ankle Society ankle-hindfoot score. Surgeries were performed by a nondesign team of orthopedic foot and ankle specialists with total ankle replacement expertise. Statistical analysis was performed by a qualified statistician. At average follow-up of 4.5 years (range, 2-6 years) complete clinical data and radiographs were available for 84 patients; 7 had incomplete data, 1 had died, 4 were withdrawn after enrolling but prior to surgery, and 4 were lost to follow-up. Results: In all outcome measures, the entire cohort demonstrated statistically significant improvements from preoperative evaluation to most recent follow-up with no statistically significant difference between the 2 groups. Radiographically, tibial lucency/cyst formation was 26.8% and 20.9% for MB-TAR and FB-TAR, respectively. Tibial settling/subsidence occurred in 7.3% of MB-TAR. Talar lucency/cyst formation occurred in 24.3% and 2.0% of MB-TAR and FB-TAR, respectively. Talar subsidence was observed in 21.9% and 2.0% of MB-TAR and FH-TAR, respectively. Reoperations were performed in 8 MB-TARs and 3 FH-TARs, with the majority of procedures being to relieve impingement or treat cysts and not to revise or remove metal implants. Conclusion: With a high level of evidence, our study found that patient-reported and clinical outcomes were favorable for both designs and that there was no significant difference in clinical improvement between the 2 implants. The incidence of lucency/cyst formation was similar for MB-TAR and FH-TAR for the tibial component, but the MB-TAR had greater talar lucency/cyst formation and tibial and talar subsidence. As has been suggested in previous studies, clinical outcomes do not necessarily correlate with radiographic findings. Reoperations were more common for MB-TAR and, in most cases, were to relieve impingement or treat cysts rather than revise or remove metal implants. Level of Evidence: Level I, prospective randomized study.

Category: Ankle, Ankle Arthritis Introduction/Purpose: Total ankle replacement as a valid treatment for end stage ankle arthritis, is gaining popularity and every year there is an increasing number of procedures. With revision rates as high as 21% at 5 years and 43% at 10 years there is a need for understanding and reporting the outcome of revision ankle replacement. Our aim was to study the patient reported outcomes following revision TAR with a minimum of 2 year follow up. Methods: All patients that underwent a revision total ankle replacement between 2012 and 2016 were included in the study. All patients received a post-operative questionnaire comprising of MOX-FQ score, EQ-5D (UK) and Foot and Ankle outcomes scores (FAOS) and patients satisfaction questionnaire with a minimum of 2 years follow up. Results: 32 patients had a revision total ankle replacement between 2012 and 2016. 2 patients were deceased therefore 30 patients were included in the study. 5 patients declined participation for completing questionnaires. We received 21 (66%) completed questionnaires. The mean MOX-FQ average domain score for pain was 58.8, walking/standing 65.8 and social function was 48.2. The mean FAOS scores were 50.7 for pain, 50.6 for symptoms, 54.9 for ADL and 28.2 for quality of life. The mean overall health score today for EQ-5D was 67.8/100. 45% of patients were satisfied with the pain relief and return to sports and recreation obtained following the operation, 48% were satisfied with the improved in daily activities. 52% were overall satisfied with the results from surgery. Conclusion: Revision total ankle replacement gives overall satisfactory results demonstrated from patients reported outcomes at a minimum of 2 years following surgery.

Category: Ankle Arthritis; Ankle Introduction/Purpose: The purpose of this study was to report on the radiographic outcomes, clinical outcomes, and implant survivorship following extramedullary-referenced (EMr) versus 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 for primary arthritis, post-traumatic arthritis, and inflammatory arthritis was enrolled in this study. Analyses were performed comparing IMr versus 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. Data was prospectively collected and retrospectively analyzed. A p-value of < 0.05 was considered significant for all statistical analyses. Results: 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). The absolute value for preoperative coronal alignment was significantly greater for IMr compared to EMr TAR (13.0 vs 6.4 degrees; p < 0.0001), but both groups achieved near neutral alignment postoperatively (1.4 vs 1.5 degrees; p=0.6655). 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-value <0.0001). There were similar improvements in patient-reported outcome scores at one year and final follow up (all p > 0.05). The 5-year implant survivorship was 98.6.% for IMr versus 97.5% for EMr at final follow-up. Conclusion: Despite the IMr TAR group having more severe preoperative coronal and sagittal malalignment, both IMr and EMr TAR components had comparable postoperative alignment, patient-reported outcome scores, and complications. Among the patients with preoperative varus, valgus, or anterior distal tibial slope, the IMr patients achieved greater correction than the EMr patients. Although the 5-year implant survivorship was similar between the two cohorts with 98.6% survival for IMr TAR and 97.5% for EMr TAR, impending failures were greater for the mobile-bearing EMr TAR.

Background: Restoration of ankle alignment is important in total ankle arthroplasty (TAA), but sagittal alignment of the talar component is less studied than coronal sagittal. Little has been published on the importance of sagittal talar alignment in TAA. The radiographic talar component inclination was hypothesized to be predictive of TAA survival, subsidence, and functional outcomes. Methods: A retrospective review of the Vancouver End-Stage Ankle Arthritis Database was performed on all TAAs at a single center over 11 years utilizing 1 of 2 implants. Talar component inclination (TCI) angles were measured and standard descriptive statistics were completed with a survival analysis. Inter- and intraobserver reliability were determined. Postoperative TCI angles were analyzed against several definitions of TAA survival and patient-reported outcome measures from the database. A total of 109 TAAs satisfied inclusion and exclusion criteria. Results: A postoperative talar component inclination angle greater than 22 degrees was associated with talar component anterior subsidence, defined as a change in that angle of 5 degrees or more between postoperative and last available radiographs. This was still significant after adjusting for confounders: age, gender, body mass index, and presence of inflammatory arthritis. All measured angles had good inter- and intraobserver reliability. Conclusion: Surgeons should avoid dorsiflexing the talar prosthesis during TAA, which hypothetically diminishes the ankle critical dorsiflexion range. This may cause anterior talar undercoverage in terminal dorsiflexion and may edge load the talar prosthesis, predisposing to anterior subsidence. Elevated TCI was a simple and reliable radiographic measurement to predict long-term TAA outcome due to predictable anterior subsidence of the talar prosthesis. Level of Evidence: Level III, retrospective comparative series.

Category: Ankle, Ankle Arthritis Introduction/Purpose: The Infinity (Wright medical) total ankle replacement (TAR) has become the most implanted ankle replacement in the UK with a 30.1% share in the most recent 2016 England and Wales NJR 14th report. It is a fixed bearing implant utilising an anterior approach and radiological guidance to aid alignment, and is approved for use in the UK as an uncemented implant. Methods: Since introducing the Infinity TAR in June 2014, all implants from two centres in the UK; The Royal Devon and Exeter Hospital NHS Foundation Trust and Northumbria NHS Healthcare Trust, have been followed up prospectively. 113 implants are included with 2 year minimum follow-up, average follow-up being 33 months (24-52). Pre- and post-operative demographic, radiographic and functional outcomes were collected including Visual Analogue Score (VAS), Manchester Oxford foot questionnaire (MOxFQ, UK validated patient reported outcome score) EQ5D (validated quality of life score). Complexity was assessed using COFAS pre-operative grade. Results: Implant survivorship was 93.8% at 2 years minimum. Median age was 68 (42-92), male: female 72:41. Mean MOxFQ improved by 28, mean EQ5D by 1.4 and mean VAS by 7. 16 cases had planned additional procedures, 5 required intra-operative medial malleolar fixation. There have been 2 revisions for deep infection, 2 for implant subsidence, 1 for instability and 2 for unexplained pain (6.2%). 5 patients have required further surgery to the ankle and hindfoot with implant retention (4.4%). 3 patients have asymptomatic tibial cysts (3.4%) and 1 patient has an asymptomatic talar cyst (0.9%) - there is no evidence of progression or loosening. Conclusion: We report favourable early functional, radiographic and survivorship outcomes of this implant in the UK population.
