Background: A number of new 2-component total ankle arthroplasty systems that emphasize minimal bone resection have been introduced for which few clinical outcomes reports are available. Our aim was to identify the rate of early revision among patients receiving the 2-component INFINITY prosthesis. Methods: Patients from 2 prospectively collected databases at the authors’ institution were screened for inclusion in the present study. All patients who underwent a primary total ankle arthroplasty (TAA) with the INFINITY prosthesis and who were at least 1 year postoperative were included. A total of 159 ankles with a mean 20 months of follow up (range, 12-37) met these criteria. All surgeries were performed by 1 of 2 orthopedic foot and ankle surgeons with extensive experience in TAA. The primary outcome was the need for revision surgery, defined as removal of 1 or both metal components. Peri-implant lucency at most recent follow-up was a secondary outcome. Weightbearing radiographs at most recent follow-up were graded for lucency independently by 2 reviewers. Results: Sixteen ankles (10%) underwent revision at a mean 13 months postoperatively. The most common reasons for revision were symptomatic tibial component loosening and deep infection (6 patients each, 3.8%). Of the 108 ankles with retained components and at least 1 year of radiographic follow-up, 8 (7.4%) had global lucency around the tibial component suggestive of loosening at most recent follow-up. Conclusions: Our initial review of patients undergoing TAA with this new 2-component prosthesis demonstrates an elevated early revision rate due to tibial component loosening compared to other implant systems. Level of Evidence: Level IV, case series.

Background: Total ankle arthroplasty is an alternative for arthrodesis. The objective of this study was to investigate the safety of trabecular-metal ankle prosthetic system with transfibular approach and external frame and its association with changes in clinical and functional scores. Methods: Between May 2013 and June 2017, a total of 104 consecutive patients underwent primary total ankle arthroplasty with a trabecular metal implant. The prospective clinical and radiographic data were collected. The mean follow-up time was 43.6 (14.6) months. Results: Of 104 patients, 88 (89%) reported improved functioning and 65 (66%) were very satisfied with the surgery. Of the patients, 51 (50%) did not report any pain at the end of follow-up at all. The average Kofoed score was 37.6 (SD 17.4) points at baseline and 74.8 (SD 20.6) points at the end of follow-up. There were 37 additional procedures, and the complication rate was nearly 20%. Conclusion: Trabecular-metal total ankle prosthesis showed promising clinical results concerning pain and function. At 5-year follow-up, osteolysis and component loosening were rare. Level of Evidence: Level IV, case series.

Category: Ankle Arthritis Introduction/Purpose: Modern total ankle arthroplasties (TAAs) have demonstrated improved survival rates at early- and mid-term follow-up, with revision rates ranging from 4 to 8% at five years. The INFINITY total ankle system (Wright Medical Technology, Arlington, TN) was first used in the United States in 2014. Its advantages include the ability to use patient-specific instrumentation and the option to choose between talar dome resurfacing and flat-cut talar components. While this implant is currently popular in the United States, clinical outcomes have not yet been reported. Our aim was to identify the rate of early revision among patients receiving the INFINITY prosthesis. Methods: Patients from two prospectively-collected databases at the authors’ institution were screened for inclusion in the present study. All patients who underwent a primary TAA with the INFINITY prosthesis and who were at least one year postoperative were included. All surgeries were performed by one of two orthopaedic foot and ankle surgeons with extensive experience in total ankle arthroplasty. The primary outcome was the need for revision surgery, which was defined as removal of one or both metal components. Peri-implant lucency at most recent follow-up was a secondary outcome. Anteroposterior and lateral radiographs at most recent follow-up were graded for lucency independently by two reviewers, both orthopaedic foot and ankle fellows, for individual peri-implant zones (Figure). Each zone was only considered “lucent” if recorded as such by both reviewers. Results: 160 patients underwent TAA with the INFINITY prosthesis between August 2014 and November 2016 with a mean 20 months of follow-up (range, 12-37). Six patients were lost to follow-up. Sixteen patients (10%) underwent revision a mean 1.2 years postoperatively. Revision was performed most commonly for tibial component loosening (seven patients, 4.4%) and deep infection (five patients, 3.1%). Of cases with tibial loosening, progressive lucency and/or subsidence was obvious radiographically in four patients; one patient had equivocal radiographs but loosening was suggested on single-photon emission computed tomography; and two patients revised for persistent pain had loosening confirmed intraoperatively. Of the 108 patients with retained components and at least one year of radiographic follow-up, eight (7.4%) had global lucency around the tibial component at most recent follow-up. Conclusion: Our initial review of patients undergoing TAA with the INFINITY prosthesis demonstrates an elevated early revision rate due to tibial component loosening. The reasons for this finding remain unclear, but could possibly include inadequate bony purchase of the implant’s three prongs, particularly in patients with large preoperative deformities or with imperfect component alignment. We plan to further investigate the possible reasons for this finding in the future by assessing additional patient factors, including age, sex, arthritis type, tobacco use, pre- and postoperative coronal and sagittal alignment, and presence of ipsilateral hindfoot fusion.

Background: The Salto Talaris is a fixed-bearing implant first approved in the US in 2006. While early surgical outcomes have been promising, mid- to long-term survivorship data are limited. The aim of this study was to present the survivorship and causes of failure of the Salto Talaris implant, with functional and radiographic outcomes. Methods: Eighty-seven prospectively followed patients who underwent total ankle arthroplasty with the Salto Talaris between 2007 and 2015 at our institution were retrospectively identified. Of these, 82 patients (85 ankles) had a minimum follow-up of 5 (mean, 7.1; range, 5-12) years. The mean age was 63.5 (range, 42-82) years and the mean body mass index was 28.1 (range, 17.9-41.2) kg/m2. Survivorship was determined by incidence of revision, defined as removal/exchange of a metal component. Preoperative, immediate, and minimum 5-year postoperative AP and lateral weightbearing radiographs were reviewed; tibiotalar alignment (TTA) and the medial distal tibial angle (MDTA) were measured to assess coronal talar and tibial alignment, respectively. The sagittal tibial angle (STA) was measured; the talar inclination angle (TIA) was measured to evaluate for radiographic subsidence of the implant, defined as a change in TIA of 5 degrees or more from the immediately to the latest postoperative lateral radiograph. The locations of periprosthetic cysts were documented. Preoperative and minimum 5-year postoperative Foot and Ankle Outcome Score (FAOS) subscales were compared. Results: Survivorship was 97.6% with 2 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 21.2% ( n = 18), with the main reoperation being exostectomy with debridement for ankle impingement ( n = 12). At final follow-up, the average TTA improved 4.4 (± 3.8) degrees, the average MDTA improved 3.4 (± 2.6) degrees, and the average STA improved 5.3 (± 4.5) degrees. Periprosthetic cysts were observed in 18 patients, and there was no radiographic subsidence. All FAOS subscales demonstrated significant improvement at final follow-up. Conclusions: We found the Salto Talaris implant to be durable, consistent with previous studies of shorter follow-up lengths. We observed significant improvement in radiographic alignment as well as patient-reported clinical outcomes at a minimum 5-year follow-up. Level of Evidence: Level IV, retrospective case series.

Background: Total ankle arthroplasty (TAA) has been developed to treat patients with end-stage ankle osteoarthritis (OA). However, there is often difficulty in treating complicated pathologies such as ankle OA with subtalar joint OA and severe talar collapse. Therefore, this study aimed to explore the short-term results and complications of TAA with total talar prosthesis, known as combined TAA, as the new techniques to treat such complicated pathology. Methods: We examined postoperative results including ankle range of motion, Japanese Society for Surgery of the Foot (JSSF) scale, and complications. There were 22 patients (15 women), with mean follow-up of 34.9 (range, 24–53 months), and the mean age was 72 (range, 62–80) years. The main indications for combined TAA included osteoarthritis (18 patients), rheumatoid arthritis (3 patients), and talar osteonecrosis with osteoarthritis (one patient). Results: The mean range of motion improved from 4.0 to 14.4 degrees in dorsiflexion and from 23.8 to 32.0 degrees in plantarflexion. The JSSF scale improved from 50.5 to 91.5 points. Prolonged wound healing occurred in 3 patients, and medial malleolus fracture occurred in 4 patients. Conclusion: Combined TAA was a reliable procedure for the treatment of not only ankle OA following avascular necrosis of talus but also of degeneration of both ankle and subtalar joints. Level of Evidence: Level IV, case series.

Background: The use of total ankle arthroplasty (TAA) in the treatment of ankle arthritis has grown substantially as advancements are made in design and surgical technique. Among the criteria guiding the choice between arthroplasty and arthrodesis, the long-term survival and postoperative outcomes are of crucial importance. Although outcomes of the INBONE I have been published, there is limited midterm survival data for the INBONE II. The purpose of this study was to determine the radiographic and patient-reported outcomes, and survivorship of this prosthesis in patients with a minimum 5-year follow-up. Methods: We retrospectively identified 51 ankles (46 patients) from 2010 to 2015 who underwent TAA with the INBONE II prosthesis at our institution. Of these, 44 cases had minimum clinical follow-up of 5 years (mean, 6.4; range 5-9). Median age was 66 years (range 42-81) and median BMI was 27.5 (range 20.1-33.0). A chart review was performed to record the incidence of revision and reoperation. Preoperative and postoperative radiographs were analyzed to assess the coronal tibiotalar alignment (TTA), the talar inclination angle, and the presence of periprosthetic lucencies and cyst formation. Preoperative and minimum 5-year postoperative Foot and Ankle Outcome Score (FAOS) subscales were compared. Survivorship was determined by incidence of revision, defined as removal of a metallic component. Results: The survivorship at 5 years was 98% and the rate of reoperation was 7.8% (n = 4); 2 patients underwent irrigation and debridement for infection, 1 patient underwent a medializing calcaneal osteotomy, and 1 patient underwent open gutter debridement, 1 patient underwent a revision of a subsided talar component at 3.2 years after index surgery. Average postoperative TTA was 88.6 degrees, with 42 rated as neutral (85-95 degrees), 2 varus (<85 degrees), and no valgus (>95 degrees) ankles. At final follow-up, asymptomatic periprosthetic cysts were observed in 8 patients. All FAOS domain scores improved between preoperative and final follow-up. Conclusion: At midterm follow-up, we observed significant improvement in radiographic alignment and patient-reported outcome scores for the INBONE II total ankle prosthesis. In addition, this cohort has had a relatively low reoperation rate and high survivorship. Level of Evidence: Level IV, case series.

Objective: The aim of this study was to determine patient satisfaction, survivorship, and revision rate of the HINTEGRA total ankle arthroplasty (TAA). Our secondary objective was to assess hindfoot function. Methods: All patients who underwent a HINTEGRA TAA between 2007 and 2014 were evaluated. We included a total of 69 patients (69 ankles), who were subjected to clinical and radiological examination and completed a visual analogue scale (VAS) for pain, the American Orthopaedic Foot and Ankle Society (AOFAS) ankle score, and the self-reported foot and ankle score (SEFAS). Hindfoot function was assessed using the AOFAS hindfoot score. Mean follow-up was 62 (57–101) months. Results: The mean VAS score was 2 (0–3) and the SEFAS was 37 (26–48) at the most recent follow-up, while the AOFAS ankle score improved from 57 (52–62) to 87 (82–93). The AOFAS hindfoot score improved from 82 to 92 postoperatively. Eight patients had periprosthetic osteolysis and 5 underwent bone grafting of cysts. We detected polyethylene and hydroxyapatite particles in specimens obtained from the cysts. Eight patients had their procedures converted to an ankle arthrodesis. Conclusion: In select patients, TAA improved quality of life. Our medium-term follow-up of the HINTEGRA TAA observed a survivorship of 89% at 5 years with an improvement in the AOFAS score and a mean SEFAS score of 37. We recommend that large periprosthetic cysts, which may be caused by the hydroxyapatite coating and polyethylene particles, be bone grafted prophylactically. We found hindfoot function to be preserved. Level of Evidence IV; Therapeutic Studies; Case Series.

Background: Treatment of failed total ankle arthroplasty (TAA) is challenging. Limited literature is available on options and outcomes of revision arthroplasty despite failure rates ranging from 10% to 23% within 10 years after primary TAA. This study reports the clinical and radiographic outcomes of revision TAA using a fixed-bearing, intramedullary-referencing implant. Methods: A retrospective review was performed of 18 consecutive revision TAA cases between 2008-2015 using an intramedullary-referencing, fixed-bearing, 2-component total ankle system. Demographic and radiographic data were collected preoperatively, immediately postoperatively, and at the most recent follow-up. Functional outcome data were collected immediately postoperatively and at mean follow-up 47.5 months. Results: Eighteen patients underwent revision TAA, with 77.8% (14/18) implant survival. Index revision was performed most commonly for aseptic talar subsidence (55.6%) or implant loosening (tibia, 29.4%; talus, 58.9%). Following revision, 22.2% (4/18) patients required reoperation at a mean 57.3 (39-86) months. Osteolysis of the tibia, talus, and fibula was present preoperatively in 66.7% (12/18), 38.9% (7/18), and 38.9% (7/18) of patients, respectively, with progression of osteolysis in 27.8% (5/18), 11.1% (2/18) and 11.1% (2/18) of patients, respectively. Subsidence of the tibial and talar revision components was observed in 38.9% (7/18) and 55.6% (10/18) of patients, respectively. The median American Orthopaedic Foot & Ankle Society (AOFAS) score was 74.5 (26-100) and Foot Function Index (FFI) score 10.2 (0-50.4). Conclusion: Early results of intramedullary-referencing revision TAA demonstrated good patient-reported outcomes with maintenance of radiographic parameters at mean follow-up of 47.5 months. Aseptic talar subsidence or loosening were the main postoperative causes of reoperation. Revision arthroplasty utilizing an intramedullary-referencing implant was a viable option for the failed TAA. Level of Evidence: Level IV, case series.

Background: Total ankle arthroplasty (TAA) has become one of the standard surgical treatments for patients with end-stage ankle osteoarthritis (OA). In recent years, TAA with total talar prosthesis (combined TAA) has been used for ankle OA patients with talar osteonecrosis, with severe talar collapse, or with subtalar joint OA. The purpose of this study was to investigate the functional and clinical outcomes of combined TAA, compared with conventional TAA. Methods: Forty-six ankles (44 patients, 32 women/12 men) that underwent conventional TAA with mean follow-up of 42 months, and 26 ankles (25 patients, 18 women/7 men) that underwent combined TAA with mean follow-up of 46 months were included. Clinical outcomes, which included ankle range of motion (ROM), the Japanese Society for Surgery of the Foot (JSSF) ankle-hindfoot scale, the Self-Administered Foot Evaluation Questionnaire (SAFE-Q), and complications were compared between the groups. Results: The preoperative ROM was significantly worse in combined TAA for both dorsiflexion and plantarflexion; however, in the final ROM, there was no significant difference between the groups. There was no significant difference in JSSF scale and SAFE-Q between the groups. Revision rate was 10.9% in conventional TAA and 0% in combined TAA. Conclusion: In this small series, at an average of 3.5 years, we found no significant difference in clinical results between conventional TAA and combined TAA; however, the revision rate was higher in conventional TAA.

Background: With the increasing use of total ankle arthroplasty (TAA), new implants with varied configurations are being developed every year. This study aimed to assess the early complications, reoperations, and radiographic and clinical outcomes of the Infinity TAA. To date, clinical results of this novel implant have not been published. Methods: A retrospective analysis of 64 consecutive ankles that underwent a primary Infinity TAA from July 2014 to April 2016 was performed. Patients had an average follow-up of 24.5 (range, 18-39) months. Medical records were reviewed to determine the incidence of complications, reoperations, and revisions. Radiographic outcomes included preoperative and postoperative tibiotalar alignment, tibial implant positioning, the presence of periprosthetic radiolucency and cysts, and evidence of subsidence or loosening. Additionally, patient-reported outcomes were analyzed with the Foot and Ankle Outcome Score (FAOS). Results: Survivorship of the implant was 95.3%. Fourteen ankles (21.8%) presented a total of 17 complications. A total of 12 reoperations were necessary in 11 ankles (17.1%). Revision surgery was indicated for 3 ankles (4.7%) as a result of subsidence of the implant. Tibiotalar coronal deformity was significantly improved after surgery ( P < .0001) and maintained during latest follow-up ( P = .81). Periprosthetic radiolucent lines were observed around the tibial component in 20 ankles (31%) and around the talar component in 2 ankles (3.1%). A tibial cyst was observed in 1 ankle (1.5%). Outcome scores were significantly improved for all FAOS components analyzed ( P < .0001), from 39.0 to 83.3 for pain, from 34.0 to 65.2 for symptoms, from 52.3 to 87.5 for activities of daily living, and from 15.7 to 64.2 for quality of life. Conclusion: Most complications observed in the study were minor and successfully treated with a single reoperation procedure or nonoperatively. Failures and radiographic abnormalities were most commonly related to the tibial implant. Further studies with longer follow-up are needed to evaluate the survivorship of the tibial implant in the long term. Level of evidence: Level IV, retrospective case series.

Background: Total ankle arthroplasty (TAA) has historically resulted in inferior survivorship rates compared with total hip and knee arthroplasty, because of technical issues unique to ankle anatomy. In this study, a single-surgeon series of intra- and postoperative complications as well as resultant reoperations/revisions of the Tornier Salto Talaris, a fixed-bearing TAA prosthesis, were reviewed. Methods: Medical records from index procedure to latest follow-up of primary TAA were reviewed. Complications were categorized according to the Glazebrook classification; additional complications were documented. Concurrent procedures were recorded, and radiographs were analyzed for alignment, subsidence, and cyst formation. Time to complication onset and learning curve analyses were performed. One hundred four Salto Talaris TAA prostheses (96 patients), with an average follow-up of 46 months, were included. Results: Thirty-five complications were identified in 32 ankles with a 34% complication rate, resulting in 11 reoperations (5 TAA revisions). Technical error (n = 12), wound healing (n = 9), and aseptic loosening (n = 4) were the most common complications, and there were no statistically significant differences in demographics or follow-up duration between cases with versus without complications. In both the cohorts with and without complications, there were moderate, negative correlations between radiographically observed keel osteopenia and lucency (ρ = −0.548, P = .00125, and ρ = −0.416, P = .000303, respectively); also, in the complication cohort, a weak, positive correlation between subsidence and lucency (ρ = 0.357, P = .0450) was found. Conclusion: Salto Talaris TAA survivorship and reoperation rates in our series were comparable with previous reports, using either the same or similar mobile-bearing prostheses; new information regarding complication, radiographic, and learning curve analyses was presented. Level of Evidence: Level IV, retrospective case series.
