Contemporary modern total ankle arthroplasty (TAA): A systematic review and meta-analysis of indications, survivorship and complication rates. Surgeon 2024; 22:174-181. [PMID: 38360453 DOI: 10.1016/j.surge.2024.01.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Revised: 08/28/2023] [Accepted: 01/25/2024] [Indexed: 02/17/2024]
Abstract
BACKGROUND This study evaluates the clinical outcomes of contemporary total ankle arthroplasty (TAAs) to primarily establish the current benefits and risks to facilitate informed decision making to secondarily establish if improvements are seen between subsequent generations of implants, bearing philosophy, and associated surgical technique. METHODS A systematic review and meta-analysis of published data from January 2000 to January 2020 was conducted following PRISMA guidelines. INCLUSION CRITERIA English language papers, adult population, ≥20 ankles with a minimum follow up ≥24 months, pre- and post-operative functional scores available. Ankle implants were characterised by generations, which were determined from the original studies and confirmed based on literature set definitions. RESULTS A total of 4642 TAAs in 4487 patients from 51 studies were included. The mean age was 61.9-years and follow up 57.8-months. Overall, 10-year survivorship rates were 77.63 %, with mobile bearing designs showing a small but significant advantage. Improved survivorship favoured the most modern implants at both two (p < 0.05), and 10-years (p < 0.01). The relative risk of a complication occurring improved with the evolution of implants e.g., nerve injury, and post-operative complications such as fracture, wound complications (e.g., dehiscence or heamatoma) and radiological abnormalities (e.g., radiolucencies, heterotopic bone formation and aseptic loosening). However, surgical site infection, and intra-operative fracture rates remain implant independent. CONCLUSIONS Modern TAA offers improved survivorship, even with a trend to lower mean implantation age, similar complexity and ever changing indications. It would appear that implant evolution has reduced risks, especially those associated with revision, without affecting functional outcomes.

Abstract
BACKGROUND Arthroscopic ankle arthrodesis (AAA) has become popular because of its higher rate of bone union, lower invasiveness, and shorter hospital stays compared to those of open arthrodesis. However, postoperative malalignment is often observed for severe varus deformity, which can cause nonunion, pain, and adjacent joint arthrosis. A compression staple can provide a persistent, strong compressive force on the bone surface. This study aimed to clarify the difference in alignment correction in AAA by comparing a compression staple and screws fixation with screws-only fixation pre- and postoperatively. METHODS Seventy ankles in 67 patients undergoing AAA were retrospectively reviewed. AAA with three screws through the distal tibia was performed in 53 ankles, and 17 ankles underwent AAA with a compression staple and two screws. After the preparation of the joint surface arthroscopically, patients in the S group had three canulated cancellous screws inserted through the medial tibia. Patients in the CS group had a compression staple placed at the lateral aspect of the tibiotalar joint and two screws inserted through the medial side. Clinical scores and pre-and postoperative alignment on plain radiographs were compared between the two procedures. RESULTS There were no significant differences in the pre-and postoperative Japanese Society for Surgery of the Foot scale. One ankle in the S group exhibited nonunion. There were no significant differences in talar tilt and tibiotalar angles between the groups. The tibial plafond angle in the CS group was significantly lower than that in the S group (p < 0.05). Postoperatively, talar tilt and tibiotalar angles on the coronal image, and the lateral tibiotalar angle in the CS group were significantly lower than those in the S group (p < 0.05). CONCLUSION AAA with a compression staple and two-screw fixations could obtain more optimal alignments than AAA with screw-only fixation, even in cases with severe varus deformity.

Abstract
Ankle arthrodesis is the gold standard for treatment of end-stage arthritis. The goal of ankle arthrodesis is to obtain bony union between the tibia and the talus. Retrograde intramedullary nailing is typically reserved for ankle and subtalar joints arthrodesis. The purpose of this study is to evaluate the effect of two different materials, two locking pin configurations and two nail designs of a retrograde locked intramedullary nail used for ankle arthrodesis. Using the finite element analysis, a numerical study of ankle arthrodesis was developed to evaluate the effect of materials: TI-6Al-4V and stainless steel AISI 316 LVM; two locking pin configurations: five and six pins, on two intramedullary nails: Ø10 × 180 mm and Ø11 × 200 mm. A model of a healthy foot was created from tomographic scans. It was found that the mechanical stimulus required to achieve bone fusion were higher for Ø10 × 180 nails (6.868 ± 0.047) than the Ø11 × 200 nails (5.918 ± 0.047; p < 0.001; mean ± SEM). We also found that six-pin configuration had a higher mechanical stimulus (6.470 ± 0.047) than the five-pin configuration (6.316 ± 0.046; p = 0.020). Similarly, it was higher for titanium (6.802 ± 0.047) than those for stainless steel (5.984 ± 0.046; p < 0.001). Finally, the subtalar zone presented higher values (7.132 ± 0.043) than the tibiotalar zone (5.653 ± 0.050; p < 0.001). The highest mechanical stimulus around the vicinity of tibiotalar and subtalar joint was obtained by Ø10 × 180 nails, made of titanium alloy, with 6P.

Abstract
PURPOSE Arthrodesis of the ankle joint is an accepted treatment option in patients with end-stage ankle arthritis. The goal is to achieve fusion between the tibia and the talus, thereby stabilizing the joint and alleviating pain. There might be associated limb length discrepancy, especially in post-traumatic and post-infectious cases. These patients require limb lengthening and arthrodesis. The purpose of this study is to report our experience with simultaneous ankle arthrodesis and lengthening using external fixation in adolescent and young adult patients. METHODS This retrospective case series included all patients treated in our hospital by concomitant ankle arthrodesis and tibial lengthening procedures on the same limb, using ring external fixation system. All surgeries included distal tibial joint surface resection and the talar dome, thereby correcting any associated deformity at the ankle. The arthrodesis was fixed and compressed using ring external fixator. A concurrent proximal tibial osteotomy was done, and limb lengthening, or bone transport was performed. RESULTS Eight patients operated between the years 2012-2020 were included in this study. Median patient age was 20.4 years (range 4-62 years), 50% women. Median limb lengthening was 20 mm (range 10-55 mm), and median final leg length discrepancy (LLD) was 7.5 mm (range 1-72 mm). The most common complication recorded was pin tract infection, which resolved with empiric antibiotics in all cases. CONCLUSION Based on our experience, combined arthrodesis and proximal tibial lengthening is efficient solution that provides stable ankle and restores length of the tibia even in complex and challenging situations.

The value of bone SPECT/CT in evaluation of foot and ankle arthrodesis and adjacent joint secondary osteoarthritis. Eur J Nucl Med Mol Imaging 2023; 51:68-80. [PMID: 37676502 DOI: 10.1007/s00259-023-06421-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2023] [Accepted: 08/28/2023] [Indexed: 09/08/2023]
Abstract
OBJECTIVE To evaluate the value of SPECT/CT (single photon emission computed tomography/computed tomography) in foot and ankle arthrodesis and development of secondary osteoarthritis in the adjacent joints. MATERIALS AND METHODS SPECT/CT of 140 joints in the foot and ankle (34 upper ankle (UA), 28 lower ankle (LA), 27 talonavicular (TN), 12 calcaneo-cuboidal (CC), and 39 other smaller joints after arthrodesis in 72 patients were evaluated retrospectively regarding fusion grade in CT (0 = no fusion, 1 = < 50% fusion, 2 = > 50% fusion, 3 = complete fusion) and radiotracer uptake (0 = no uptake, 1 = mild uptake, 2 = moderate uptake, 3 = high uptake) on SPECT/CT. Severity of osteoarthritis (1 = mild, 2 = moderate, 3 = severe) and radiotracer uptake grade in adjacent joints was also assessed. In 54 patients, clinical information about interventions in the follow-up was available. RESULTS According to the SPECT/CT, arthrodesis was successful (grade 2 or 3 CT fusion and grade 0 or 1 uptake) in 73% (25/34) of UA joints, 71% (20/28) of LA joints, 67% (18/27) TN, 100% (12/12) CC joints, and 62% (24/39) of other smaller joints. In 12 joints, there were discrepant findings in SPECT/CT (fusion grade 2 and uptake grade 2 or 3 (n = 9); or, fusion grade 0 or 1 and uptake grade 1 (n = 3)). The fusion rate 6-12 months after arthrodesis was 42% (14/33), 59% (20/34) after 13-24 months, and 89% (65/73) after more than 24 months, respectively. Average radiotracer uptake in arthrodesis decreased with age: 6-12 months: 1.60, 12-24 months: 1.32, > 24 months: 0.38. There was a significant negative correlation between radiotracer uptake grade and CT fusion grade. Osteoarthritis was observed in 131 adjacent joints. During the post scan follow-up, additional arthrodeses were performed in 33 joints, of which 11 joints were re-arthrodesis and 22 were new arthrodeses in osteoarthritic adjacent joints. All these 11 joints with failed arthrodesis had grade 0 of CT fusion and grade 2 or 3 of radiotracer uptake. All 22 adjacent joints with osteoarthritis, which subsequently underwent arthrodesis, had grade 2 or 3 radiotracer uptake, and the primary arthrodesis joints were healed and fused in all these cases. CONCLUSION Bone SPECT/CT is a valuable hybrid imaging tool in the evaluation of foot and ankle arthrodesis and gives additional useful information about the development of secondary osteoarthritis in the adjacent joints with higher value for the assessment of secondary osteoarthritis. A practical four-type classification ('Lucerne Criteria') combining metabolic and morphologic SPECT/CT information for evaluation of arthrodesis joints has been proposed.

Abstract
Introduction Tibiotalocalcaneal arthrodesis (TTCA) is a well-known and accepted surgical technique for end-stage ankle osteoarthritis. The aim of this study is to compare the postoperative clinical and radiological comparison of retrograde intramedullary nailing (RIMN) and plate/cannulated screw (P/cS) fixation methods in patients undergoing TTCA. Methods Patients with end-stage ankle osteoarthritis due to traumatic causes or rheumatic diseases between December 2012 and March 2019 were included in the retrospective study. Patients who underwent isolated tibiotalar or isolated subtalar arthrodesis were not included in the study. Functional scores of patients with bone fusion were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) and Short Form-36 (SF-36) quality of life score surveys, administered either in person or by phone. From the radiological point of view, it was evaluated whether the union was achieved with the two-view ankle radiograph. There were 48 patients who underwent ankle arthrodesis in the clinical archive. A total of 31 patients were excluded from the study due to failure to attend follow-up, inability to be reached, or non-compliance with study criteria. The mean age of the patients participating in the study was 44.12 ± 12.95 years, the follow-up time was 40.06 ± 27.31 months, the union time was 5.19 ± 3.17 months, and the AOFAS score was 53.12 ± 13.87. SF-36 scores were evaluated among their own subunits. Results A total of 17 patients were enrolled in the study, of whom 13 were male (76.47%) and 4 were female (23.53%). There was no significant effect of the fixation methods (RIMN or P/cS) selected for TTCA on union times (p>0.05). However, there were significant differences in some parameters of the SF-36 when compared by gender. According to this, the scores of men in physical function (PF), mental health (MH), and general health perception (GHP) were higher than those of women. When AOFAS and SF-36 scores were compared by fixation type, no statistically significant difference was found (p>0.05). Conclusion This study investigated the impact of the fixation method on clinical and radiological outcomes in TTCA. We found that both methods were clinically similar in terms of bone union time and surgical efficacy. However, men had better physical function, mental health, and general health perception after TTCA than women.

Abstract
Obesity is a growing problem defined as a body mass index of greater than 30 kg/m2. It is predicted that by 2030, 48.9% of adults will be classified as obese which expands surgical risk factors to a broad population while increasing healthcare costs at the same time in different socioeconomic groups. This specific population has been widely studied in multiple surgical fields and published studies have shown the implications in each of these fields. The impact of obesity on orthopedic surgical outcomes has been previously reported in several total hip and knee arthroscopy studies, with evidence indicating that obesity is strongly associated with an increased risk of post operative complications together with higher revision rates. In line with increasing interest on the impact of obesity in orthopedics, there has been a similar output of publications in the foot and ankle literature. This review article evaluates several foot and ankle pathologies, their risk factors associated with obesity and subsequent management. It provides an updated, comprehensive analysis of the effects of obesity on foot and ankle surgical outcomes, with the ultimate aim of educating both surgeons and allied health professionals about the risks, benefits, and modifiable factors of operating on obese patients.

Abstract
Background Percutaneous ankle fusion is an emerging technique with minimal published outcome data. The goal of the present study is to retrospectively review clinical and radiographic outcomes following percutaneous ankle fusion and provide technique tips to perform percutaneous ankle fusion. Methods Patients >18 years of age, treated by a single surgeon, from February 2018 to June 2021, who underwent primary isolated percutaneous ankle fusion supplemented with platelet-derived growth factor B (rhPDGF-BB) and beta-tricalcium phosphate, with at least 1-year follow-up were included. Surgical technique consisted of percutaneous ankle preparation followed by fixation with 3 headless compression screws. Pre- and postoperative visual analog scale (VAS) and Foot Function Index (FFI) were compared using paired t tests. Fusion was assessed radiographically by the surgeon on postoperative radiographs and computed tomography (CT) at 3 months postoperatively. Results Twenty-seven consecutive adult patients were included in the study. Mean follow-up was 21 months. Mean age was 59.8 years. Mean preoperative and postoperative VAS scores were 7.4 and 0.2, respectively (P < .01). Mean preoperative FFI pain domain, disability domain, activity restriction domain, and total score were 20.9, 16.7, 18.5, and 56.4, respectively. Mean postoperative FFI pain domain, disability domain, activity restriction domain, and total score were 4.3, 4.7, 6.7, and 15.8, respectively (P < .01). Fusion was achieved in 26 of 27 patients (96.3%) at 3 months. Four patients (14.8%) had complications. Conclusion We found in this cohort with surgery performed by a surgeon highly experienced in minimally invasive surgery that percutaneous ankle fusion augmented with a bone graft supplement achieved a high rate of fusion (96.3%) and a significant improvement in pain and function postoperatively while associated with minimal complications.

Rate of progressive healing with a carbon-fiber orthosis in cases of partial union and nonunion after ankle arthrodesis using the Ilizarov external fixator. J Foot Ankle Res 2023; 16:15.

Abstract
BACKGROUND The Ilizarov fixator is a popular device for treating arthrodesis of the ankle joint in complex situations. However, the therapy can fail, with nonunion or partial union that might not be load stable. There is the possibility of follow-up surgery or extended wearing of the fixator. Full weight bearing with a carbon orthosis remains another treatment option, which has not yet been investigated.The aim of the study was to determine the rate of progress that can be obtained with a carbon orthosis in cases of partial union or nonunion after fixator removal. METHODS In this retrospective observational study thirty-three patients received a carbon orthosis after fixator removal due to nonunion or partial union. All patients were allowed to walk with the orthosis under full load. The consolidation rate was determined radiologically and compared with the imaging data obtained during the last follow-up. In addition to demographic data, the Foot and Ankle Ability Measure and pain using a numeric rating scale were determined. Nine patients had to be excluded due to insufficient follow-up, and finally n = 24 patients were included in the study. RESULTS The average duration of fixator use was 21 weeks (range 15-40 weeks), and the total average follow-up after removal of the fixator was 16 months (range 4- 56). For 14 (58.33%) patients, there was a further increase in consolidation with the orthosis after the fixator was removed. CONCLUSION The results show that if there is only partial union or nonunion, further consolidations can be achieved after the application of a carbon orthosis. In a difficult patient population, using an orthosis should therefore be attempted to avoid unnecessary revision operations.

Abstract
Ankle arthrodesis has become a common surgical procedure for individuals with end-stage ankle arthritis, chronic infection, and bony misalignment. Although arthrodesis is typically managed with arthrodesis in situ or realignment, reconstruction may be utilized for patients with more complicated cases that involve metatarsal defects. Our institution utilizes both the pedicled and free fibula flaps for surgical management pertaining to ankle arthrodesis. Our study looks to evaluate the work of a single plastic surgeon and identify patient postoperative outcomes.

Abstract
UNLABELLED This second of a 2-part series of articles recounts the key points presented in a collaborative symposium sponsored jointly by the Arthritis Foundation and the American Orthopaedic Foot & Ankle Society with the intent to survey current treatment options for osteoarthritis (OA) of the foot and ankle. A meeting was held virtually on December 10, 2021. A group of experts were invited to present brief synopses of the current state of knowledge and research in this area. Topics were chosen by meeting organizers, who then identified and invited the expert speakers. Part 2 overviews the current treatment options, including orthotics, non-joint destructive procedures, as well as arthroscopies and arthroplasties in ankles and feet. Opportunities for future research are also discussed, such as developments in surgical options for ankle and the first metatarsophalangeal joint. The OA scientific community, including funding agencies, academia, industry, and regulatory agencies, must recognize the importance to patients of addressing the foot and ankle with improved basic, translational, and clinical research. LEVEL OF EVIDENCE Level V, review article/expert opinion.

Abstract
CASE We report 2 cases of severe arthrogrypotic clubfeet presenting with multiplanar ankle deformities. Two patients (3 ankles) were treated with deformity-correcting ankle fusions using 3D preoperative planning and 3D-printed patient-specific cut guides. This technique enabled safe, accurate, and efficient surgical correction with good clinical outcomes. At 1 year, physical function and patient outcome measures improved. CONCLUSION In the setting of complex multiplanar deformities of the foot and ankle, the use of 3D preoperative planning and 3D-printed cut guides is a safe and accurate adjunct to ankle fusion.

Abstract
Background: Ankle arthroplasty has emerged as a viable alternative to ankle arthrodesis due in large part to recent advancements in both surgical technique and implant design. This study seeks to document trends of arthroplasty and arthrodesis for ankle osteoarthritis in New York State from 2009-2018 in order to determine if patient demographics play a role in procedure selection and to ascertain the utilization of each procedure and rates of complications. Methods: Patients 40 years and older from 2009-2018 were identified using International Classification of Diseases, Ninth and Tenth Revisions (ICD-9 and ICD-10), Clinical Modification (CM) diagnosis and procedure codes for ankle osteoarthritis, ankle arthrodesis, and ankle arthroplasty in the New York statewide planning and research cooperative system database. A trend analysis for both inpatient and outpatient procedures was performed to evaluate the changing trends in utilization of ankle arthrodesis and ankle arthroplasty over time. A multivariable logistic regression was used to assess the odds of receiving ankle arthrodesis relative to ankle arthroplasty. Complications were compared between inpatient ankle arthrodesis and arthroplasty using multivariable Cox proportional hazards regression. Results: A total of 3735 cases were included. Ankle arthrodesis increased by 25%, whereas arthroplasty increased by 757%. African American race, federal insurance, workers compensation, presence of comorbidities, and higher social deprivation were associated with increased odds of having an ankle arthrodesis vs an ankle arthroplasty. Compared with ankle arthroplasty, ankle arthrodesis was associated with increased rates of readmission, surgical site infection, acute renal failure, cellulitis, urinary tract infection, and deep vein thrombosis. Conclusion: Ankle arthroplasty volume has grown substantially without a decrease in ankle arthrodesis volume, suggesting that ankle arthroplasty may be selectively used for a different population of patients than ankle arthrodesis patients. Despite the increased growth of ankle arthroplasty, certain patient demographics including patients from minority populations, federal insurance, and from areas of high social deprivation have higher odds of receiving arthrodesis. Level of Evidence: Level III, retrospective cohort.

Does Concurrent Distal Tibiofibular Joint Arthrodesis Affect the Nonunion and Complication Rates of Tibiotalar Arthrodesis? J Clin Med 2022; 11:jcm11123387. [PMID: 35743458 PMCID: PMC9224582 DOI: 10.3390/jcm11123387] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2022] [Revised: 06/04/2022] [Accepted: 06/09/2022] [Indexed: 02/04/2023] Open
Abstract
Tibiotalar arthrodesis successfully treats ankle arthritis but carries risk of nonunion. It is unclear whether concurrent distal tibiofibular arthrodesis affects tibiotalar nonunion rate. The purpose of this study is to compare tibiotalar nonunion and complication rates in patients with versus without a distal tibiofibular arthrodesis. This is a retrospective review of 516 consecutive ankle arthrodesis performed between March 2002 and May 2016. A total of 319 ankles (312 patients) underwent primary, open tibiotalar arthrodesis (227 with distal tibiofibular arthrodesis, 92 without). Primary outcome measure was nonunion rate. Secondary outcome measures were time to tibiotalar union, rate of development of post-operative deep vein thrombosis (DVT)/pulmonary embolism (PE), rate of deep wound complications, and rate of return to operating room (OR). No differences in nonunion rates were observed in both cohorts of patients with versus without distal tibiofibular arthrodesis: 17/227 (7.5%) versus 11/92 (12%) (p = 0.2), respectively, odds ratio was 0.74, 95% CI: 0.29~2.08 (p = 0.55). There was no difference in deep wound complications (5.3% versus 10.9%, p = 0.42), time to union (3.7 months versus 4.1 months, p = 0.72), or rate of development of DVT/PE (5.2% versus 2.2%, p = 0.18) between patients with and without distal tibiofibular arthrodesis, respectively. This is the first study directly comparing nonunion and complication rates in primary, open ankle arthrodesis with and without distal tibiofibular arthrodesis. Inclusion of the distal fibular joint with the tibiotalar fusion was not associated with a change in tibiotalar nonunion rate, time to union, wound complications, or postoperative DVT/PE.

Subtalar arthrodesis using a single compression screw: a comparison of results between anterograde and retrograde screwing. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2021; 32:1583-1589. [PMID: 34623469 DOI: 10.1007/s00590-021-03141-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/01/2021] [Accepted: 06/28/2021] [Indexed: 10/20/2022]
Abstract
INTRODUCTION The primary objective of this study was to compare the radiological and clinical results of anterograde and retrograde screwing in subtalar arthrodesis using a single compression screw. The secondary objective was to evaluate the subjective results and consolidation of this procedure. The hypotheses were that isolated screw fixation was sufficient to achieve good consolidation and that there was no difference between the two techniques with a similar rate of bone fusion. METHODS This is a monocentric, retrospective, radio-clinical study based on 99 patients (101 feet), 58 males and 41 females, with an average age of 64 years. The main aetiology was post-traumatic osteoarthritis, which represented 51% of cases. Two groups were formed: group A (52 feet) consisting of fixed arthrodesis with ascending (retrograde) screwing and group D (49 feet) consisting of fixed arthrodesis with descending (anterograde) screwing. The two groups were statistically comparable in terms of demographic data as well as aetiologies and comorbidities. Arthrodeses which were not fused at 6 months were reassessed at one year and in the event of any radio-clinical doubt regarding consolidation, an additional CT scan was prescribed. Average post-operative follow-up was 11 ± 5 years (2-27 years). RESULTS Ninety-two arthrodeses (93%) were fused at one year and 9 were considered to be in non-union, 5 (9.8%) in group A, and 4 (8.3%) in group D. We recorded 30 complications, 22 of which were due to a conflict with the screw head, 18 (34.5%) in group A and 4 (8.3%) in group D (p = 0.03). Conflict between the screw head and the heel led to the removal of the screw after consolidation of the arthrodesis. The clinical results were evaluated using Odom's criteria. Nine per cent of patients described their results as excellent, 29% as good, 51% as satisfactory and 11% found the result to be poor. CONCLUSION The fusion rate for isolated compression screw arthrodesis is good, and there is no difference between anterograde and retrograde screws. However, the discomfort caused by the screw head being insufficiently embedded in the retrograde group led to a non-negligible number of additional surgeries to remove the screw.

Abstract
BACKGROUND Pilon fractures are severe, intra-articular and comminuted fractures to the distal tibia. They are uncommon injuries and are often associated with fibular fractures. The optimal management of these fractures is widely debated. Open reduction and internal fixation (ORIF) and external fixation have been used to treat these fractures. Ankle arthrodesis is often used in the latter stages of management for end-stage ankle arthritis. The aim of this systematic review was to identify the outcomes associated with using primary ankle arthrodesis in pilon fractures. METHODS Ovid Medline and PubMed were searched from the inception of their databases until October 2018. Eligible literature for use in our review included patient cohorts that had been operated in the form of primary ankle arthrodesis. All relevant data was included that met the inclusion criteria. The demographic of the patients with pilon fractures and this operative management were identified. The outcomes of interest were fusion rate, infection rate, length of follow-up and patient reported outcomes. 8 papers were deemed eligible for review. RESULTS Of the 8 papers that were eligible, 6 were retrospective studies, 1 was a case report and 1 was an abstract. There were a total of 109 patients included. Fusion rate was 100% in 5 of the studies. 6 of the 7 studies that reported on infection rate had no post-operative infections. Outcome assessment scores were used in 5 of the studies. The SF-36 score, the FOAS and the AOFAS were used. CONCLUSIONS This review shows that primary ankle arthrodesis yields reasonable results in the management of pilon fractures. However, the quantity and quality of current literature is not sufficient and further studies with larger cohorts and longer follow-up times are warranted.

Abstract
BACKGROUND Arthrodesis is considered the gold standard for end-stage ankle arthritis in patients who fail conservative management. Achieving union is paramount while minimizing complications. An essential item for successful union is preparation of the articular surface. Our study aims to evaluate the difference in joint preparation between direct lateral and dual mini-open approaches. MATERIALS AND METHODS Ten below knee fresh-frozen specimens were used for this study. Five were prepared through lateral approach, and five using dual mini-incisions. After preparation, all ankles were dissected and images of tibial plafond and talar articular surfaces were taken. Surface areas of articulating facets and unprepared cartilage of talus, distal tibia, and distal fibula were measured and analyzed. RESULTS A greater amount of total surface area was prepared with the mini-open approach in comparison to the transfibular approach. Percentage of prepared surface area of total articulating surface (including talus and tibia/fibula), talus, tibia, and fibula with the transfibular approach were 76.9%, 77.7%, and 75%, respectively. Percentages were 90.9%, 92.9%, and 88.6% with the mini-open approach. When excluding medial gutter, there was no significant difference between techniques (83.94% vs. 90.85%, p = 0.1412). CONCLUSION Joint preparation with the mini-open approach is equally efficacious as the transfibular approach for the tibiotalar joint. The mini-open approach does provide superior preparation of the medial gutter and inferior tibial surface which may help to increase union rates and decreased complications. LEVEL OF EVIDENCE V.

Abstract
In order to address complex extremity injuries, the orthoplastic approach uses plastic, orthopedic, and microsurgical techniques and includes other disciplines to optimize limb salvage. This collaboration, if created early in treatment, allows for more expedient and individualized solutions to a variety of extremity injuries resulting in decreased hospital stay, fewer complications, and improved functional outcomes. The orthoplastic approach does not merely avoid amputation, but also improves patient function and quality of life in the short and long term.

Abstract
BACKGROUND The internet is an important source of information for patients undergoing surgery. Multiple studies have identified inappropriately high reading levels of patient information online. The average reading level in the United States is 7-8th grade. Multiple organisations have recommended that patient information not exceed 6th grade level. This study aims to evaluate the reading levels and quality of information regarding ankle fusion surgery online. METHODS Google, Bing and Yahoo were searched (MeSH "ankle fusion", "ankle arthrodesis") and the top 30 URLs analysed. Readability was assessed using an online readability calculator to produce 3 scores (Gunning FOG, Flesch Kincaid Grade and Flesch Reading Ease). Quality was assessed using a HONcode detection web-extension and the JAMA benchmark criteria. RESULTS Ninety-eight webpages were identified. The mean Flesch Kincaid Grade level was 9.24 ± 2.33 (95% CI 8.78-9.71). The mean Gunning FOG grade was 10.88 ± 3.1 (95% CI 10.26-11.5). The mean Flesch Reading Ease score was 49.88 ± 14.46 (95% CI 46.98-52.78). 7 webpages were at or below the 6th grade reading level. The mean JAMA score was 1.34 ± 1.32 out of 4 (95% CI 1.07-1.6). 14 websites were HONcode accredited. CONCLUSION The overall readability of medical information online is too high for the average patient. Given the important role that health literacy provides in patient reported outcomes, improving the readability and quality of these materials is imperative. Awareness by the general public is essential for them to critically appraise the information they receive online.

Abstract
To analyze the efficacy of arthrodesis with Ilizarov external fixator for the treatment of end-stage ankle osteoarthritis.This retrospective study included 88 patients with end-stage (stage-3) ankle osteoarthritis according to Morrey-Wiedeman classification who underwent arthrodesis with Ilizarov external fixator from January 2016 to January 2019. There were 47 males and 41 females with a mean age of (57.21 ± 7.12) years old (range 49-76). Outcomes were measured by the American Orthopaedic Foot and Ankle society (AOFAS) Ankle Hindfoot Scale, Visual Analog Scale (VAS) pain scores, complications, subjective satisfaction, ankle function, correction of deformity, and complications.With an average follow-up of (13.50 ± 5.41) months (range 10-21), all 88 patients returned for final follow-up. All patients achieved bony healing with a success rate of 100%. Mean postoperative healing time (3.56 ± 1.04) months (range 3-6). Two patients developed sinus tract infection, delayed healing in 1 patient, and 2 patients had pain and swelling again in the ankle joint. No serious complications occurred in other patients. All the patients evaluated with the VAS scores and AOFAS scores at final follow-up showed significant improvement (P < .05). Through imaging analysis, medical tibial talar angle (MTTA) improved from (85.76 ± 6.01) degrees to (88.98 ± 1.35) degrees postoperative. Lateral talar station (LTS) decreased from (5.32 ± 3.81) mm to (2.71 ± 2.62) mm after operation (P < .05). The overall satisfaction of patients is 88.64%.In the treatment of end-stage ankle osteoarthritis, arthrodesis with Ilizarov external fixator can achieve good radiological and clinical outcomes with low prevalence of ankle joint malalignment and high fusion rates and satisfaction.

A modified transfibular technique of ankle arthrodesis using partial fibular resection and onlay bone graft. PLoS One 2020; 15:e0241141. [PMID: 33091091 PMCID: PMC7580892 DOI: 10.1371/journal.pone.0241141] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2020] [Accepted: 10/08/2020] [Indexed: 11/19/2022] Open
Abstract
The transfibular approach is a common procedure for tibiotalar fusion. However, this technique has several concerns: inadequate stability to resist rotational and shearing forces, a fibula is suboptimal for bone grafting, and an onlay fibular graft that might prevent impacting and cause distraction. We present a modified transfibular technique using partial fibular resection and onlay bone graft, which may address these potential problems. This study aimed to evaluate whether the ankle joint is well fused with neutral alignment and functionally improved at the final follow-up. For this study, 27 consecutive patients (mean age, 68.5 years; range, 58–83) who underwent tibiotalar fusion with a follow-up period of >1 year were retrospectively included. A modified transfibular lateral approach was performed, in which the distal anterior half fibula was resected and fixed as an onlay graft to achieve fusion between the tibia, fibula, talus, and fibular onlay graft simultaneously. Radiographic outcomes were assessed using computed tomography at 4 months after operation and serial follow-up radiographs. Functional outcomes were assessed using the American Orthopedic Foot and Ankle Society hindfoot scale and Foot and Ankle Outcome Score. The mean follow-up period was 17.3 (range, 12–32) months. Four months after operation, complete union was achieved in 13 patients, near-complete union in 8 patients, and partial union in the remaining 6 patients. At the final follow-up, all the patients achieved complete union and maintained neutral ankle alignment. The functional outcome showed a significant increase between the preoperative and postoperative periods. One minor complication occurred, in which medial side ankle pain was relieved after screw removal. This modified technique is safe and effective, and has several merits, including saving the soft tissue of the anterior ankle, saving the course of the peroneal tendons by leaving the posterior half of the fibula, resected fibula serving as a good bone stock, and reducing the likelihood of valgus deformity after fibulectomy.

Functional and radiological medium term outcome following supramalleolar osteotomy for asymmetric ankle arthritis- A case series of 33 patients. J Orthop 2020; 21:500-506. [PMID: 32999538 DOI: 10.1016/j.jor.2020.08.038] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/27/2020] [Revised: 08/28/2020] [Accepted: 08/31/2020] [Indexed: 02/07/2023] Open
Abstract
Introduction Ankle arthritis is one of the most disabling and painful conditions. Up to 37.5% of ankle arthritis presents as asymmetric arthritis with ankle malalignment. Supramalleolar osteotomy is a joint sparing operation, which aims to realign the ankle joint that will prevent progression of arthritis and relieve patient's symptoms. Aim The aim of this study is to analyse the medium term functional and radiographic outcomes of patients who underwent supramalleolar osteotomy for asymmetric ankle arthritis. Materials and methods This is a retrospective outcome study of medium term outcome for 33 patients who underwent Supramalleolar osteotomy for asymmetric ankle arthritis by a single surgeon. We assessed the functional outcome of the patients with AOFAS and VAS score. The radiological parameters measured were Tibial articular surface ankle (TAS), Hind foot alignment angle (HFA) and Talar tilt angle (TT). We used the paired Student's t-test to compare the preoperative and postoperative radiographic measurements, AOFAS and VAS scores. We set the significance level at P < 0.05. Results We had 21 patients who underwent lateral closing wedge osteotomy for varus deformity and 12 patients who underwent medial closing wedge osteotomy for valgus deformity. The mean followup was 72 months [29-73]. The mean AOFAS score significantly improved by 44.82 ± 7.97 (p < 0.0001). The VAS score significantly improved by 5.06 ± 1.41 (p < 0.0001). All the radiological parameters showed statistically significant improvement. All osteotomy united by 8-10 weeks. We had one case of late deep wound infection, which settled down with by metalwork removal. The arthritis progressed in three cases, two patients had fusion and one patient had ankle replacement. We had 90.9% survival rate for our osteotomy at 6 years. Conclusion Supramalleolar osteotomy is an excellent option for patients with asymmetric ankle arthritis with good functional and radiological outcome and good medium term survival rate.

Woo BJ, Lai MC, Ng S, Rikhraj IS, Koo K. Clinical outcomes comparing arthroscopic vs open ankle arthrodesis. Foot Ankle Surg 2020; 26:530-534. [PMID: 31257043 DOI: 10.1016/j.fas.2019.06.004] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/11/2019] [Revised: 05/14/2019] [Accepted: 06/13/2019] [Indexed: 02/04/2023]
Abstract
BACKGROUND Over the last twenty years, minimally invasive ankle arthrodesis has evolved into a well-tolerated and safe procedure. It has grown in favor to open ankle arthrodesis due to shorter length of stay and fewer complications recorded. This paper aims to compare the clinical outcomes of arthroscopic vs open ankle arthrodesis at 24-months followup. METHODS From 2004 to 2015, we reviewed a prospectively collected database in a tertiary hospital foot and ankle registry. 28 feet that underwent arthroscopic ankle arthrodesis were matched to 56 feet that underwent open ankle arthrodesis for age, sex and body mass index (BMI). Visual analogue scale (VAS) scores, American Orthopaedic Foot & Ankle Society (AOFAS) Ankle-hindfoot Scores and Short Form Health Survey (SF-36) were obtained to assess clinical outcomes. These parameters were collected before surgery, at 6months and 24months after surgery. RESULTS The arthroscopic group demonstrated significant less pain in the perioperative period (arthroscopic: 1.9±1.2, open: 3.8±1.1, p<0.001) and shorter length of hospitalization stay (arthroscopic: 2.1±0.7 open: 3.5±1.7, p<0.001). Patients who underwent arthroscopic ankle arthrodesis also reported a higher SF-36 score on physical functioning at 6months (arthroscopic: 58.4±27.1, open: 47.1±24.0, p<0.05) and higher AOFAS Ankle-hindfoot Scale score at 24-months (arthroscopic: 78.9±18.9, open: 68.9±24.7, p<0.05). There were no postoperative complications in the arthroscopic group but 11 in the open group, including 9 which required followup operations. There was no significant difference in length of operative procedure between both groups. CONCLUSIONS We conclude that the arthroscopic group displayed better clinical outcomes compared to the open group at the 24months followup. The advantages of arthroscopic ankle arthrodesis include significantly less perioperative pain, higher AOFAS Ankle-hindfoot scores at 24months, shorter length of stay, fewer postoperative complications and followup operations. LEVEL OF EVIDENCE Level III, retrospective comparative series.

Abstract
BACKGROUND Arthrodesis of the ankle is a salvage procedure in case of chronic ankle joint infection. External fixation still is the gold standard. We compared the outcome of external fixator versus intramedullary nailing for arthrodesis of the infected ankle joint. METHODS All patients with ankle joint infection who received arthrodesis with either external fixator or intramedullary nail between 08/2009 and 09/2017 were retrospectively analyzed. Endpoints were the successful control of infection, osseous fusion, and mobilization with full weightbearing. RESULTS Seventy-one patients were included. Nineteen patients (27%) suffered reinfection. Patients with intramedullary nailing showed significantly fewer reinfections (p=0.019), achieved full weightbearing significantly more often (p=0.042) and faster and developed significantly fewer complications (p<0.001). Forty-three patients showed bone fusion without significant differences between the groups. CONCLUSIONS Ankle arthrodesis with intramedullary nailing appears to be a successful alternative to the established procedure of external fixation in cases of chronic ankle joint infection.

Abstract
BACKGROUND The purpose of this study was to compare the clinical and radiographic outcomes of stabilization of the lateral ligament combined with joint debridement in patients with ligamentous moderate neutral ankle osteoarthritis with those achieved for patients with varus ankle osteoarthritis. METHODS We reviewed integrated data from 40 patients (40 ankles) with ligamentous moderate ankle osteoarthritis. Matched for age, gender, and follow-up duration, they were divided into two groups by preoperative coronal plane hindfoot moment arm values (HMAV): neutral (20 ankles, ≤15 mm) and varus (20 ankles, >15 mm) deformity. Stabilization of lateral ligament combined with joint debridement was performed. American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hind foot score, hindfood moment arm values, and classification of Takakura were used to compare clinical and radiographic outcomes after a mean follow-up period of 64.2 months (range, 60-84 months). RESULTS Mean post-operative AOFAS was 86.0 and 72.6 in the neutral and varus groups, respectively. The post-operative AOFAS of both groups improved significantly, although the outcome improvement of the neutral group was better than that of the varus group (P = 0.0006). There was obvious improvement in HMAV of the neutral group (P = 0.0469) and less improvement in HMAV of the varus group (P = 0.8509). The mean postoperative HMAV was 4.60 mm (0-10 mm) and 17.85 mm (8-23 mm) in the neutral and varus groups, respectively. The radiographic classification of Takakura was unchanged in the neutral group, whereas four cases in the varus group had a worse classification. CONCLUSIONS Stabilization of the lateral ligament combined with joint debridement for ligamentous moderate ankle osteoarthritis showed better clinical and radiographic outcomes in patients with neutral alignment than that achieved for patients with varus malalignment.

Abstract
BACKGROUND With longer follow-up, survival rate of total ankle replacements (TAR) diminishes. It is therefore important to have a reliable fall-back option in case of failed TAR. Revision arthroplasty is often impossible because of loss of bonestock or infection. Conversion to ankle fusion is then indicated. We investigated the clinical, radiographic and patient reported results for fusion after failed TAR in a consecutive group of patients. We concentrated on the influence of inflammatory joint disease (IJD) on union rate. METHODS Patient files and radiographic images of 46 consecutive patients (47 ankles) were reviewed. There were 22 patients with IJD. Fixation methods included; anterior plating, blade plate fixation, intramedullary nailing, compression screws and external fixation. Foot and Ankle Outcome Score (FAOS) and Foot and Ankle Ability Measure (FAAM) were used to determine patient related outcomes. RESULTS Forty out of 47 ankles (85%) Fused. Union rate in the non-IJD group (96%) was significantly higher compared to the IJD-group (73%, p=0.04). Revisions and complications were more frequent in the IJD group, but numbers were too small to detect a significant difference. Mean PROM scores were: FAOS-symptoms; 68.5, FAOS-pain; 70.3, FAOS-QoL; 43.7, FAOS-ADL; 68.1 and FAAM-ADL; 52.1, with no significant difference between IJD and non-IJD patients. CONCLUSIONS IJD-patients have a higher nonunion rate after ankle fusion for failed TAR. However, patient reported outcome is not significantly different between the two groups.

Abstract
Background and purpose - Arthrodesis is the most common treatment of severe ankle arthritis. Large studies on the occurrence of re-arthrodesis are few, especially with information in terms of risk. We used the National Swedish Ankle Registry to assess incidence and risk factors for re-arthrodesis. Patients and methods - In the Registry, we examined the occurrence of re-arthrodesis in 1,716 patients with a primary ankle arthrodesis. We also analyzed associations between the re-arthrodesis risk and sex, diagnosis, and surgical method. Results - The risk of first re-arthrodesis at 2.5 years was 7.4% and the rate at 9 years 7.8%. The risk following arthroscopic surgery with fixation by screws was 15%, which is statistically significantly higher than the 8% following the gold standard technique with open screw fixation, the 5% following fixation by intramedullary nailing, and the 3% following fixation by plate and screws. Patients with either idiopathic osteoarthritis or posttraumatic arthritis had a higher risk of re-arthrodesis than patients with rheumatoid arthritis. We could not find that the risk of re-arthrodesis was associated with sex. Interpretation - In Sweden, the re-arthrodesis risk varied by primary technique and was especially high after arthroscopic surgery. Reasons are unknown but poor surgical technique and/or surgeon inexperience may contribute, as may patient selection.

Abstract
BACKGROUND The main indication for the supramalleolar osteotomy is asymmetric ankle osteoarthritis with concomitant supramalleolar valgus or varus deformity. The aim of this prospective study was to analyze short-term clinical and radiographic outcomes in patients with asymmetric ankle osteoarthritis. METHODS A total of 16 patients with asymmetric ankle osteoarthritis and concomitant supramalleolar deformity - 7 patients with valgus deformity, 9 patients with varus deformity - were treated. Intraoperative and postoperative complications were recorded and analyzed. The clinical and radiographic outcomes were assessed after a mean follow-up of 3.6 ± 1.1 years. RESULTS In 10 of 16 patients, removal of hardware was performed. The AOFAS hindfoot score increased significantly after surgery. All categories of the SF-36 score showed significant improvement. The average range of motion also increased significantly. Radiographic assessment showed neutral hindfoot alignment at the latest follow-up. The postoperative clinical outcomes were comparable in both patient groups. The time until complete osseous union was significantly longer in patients with opening wedge osteotomy. CONCLUSION This prospective study demonstrated encouraging short-term results in patients with asymmetric ankle osteoarthritis who underwent supramalleolar osteotomy. In progressive ankle osteoarthritis, joint-nonpreserving treatment options including total ankle replacement or ankle arthrodesis should be discussed.

Abstract
Objective To accurately drill the Kirschner wire with the help of the 3D-printed personalized guide and to evaluate the feasibility of the 3D technology as well as the outcome of the surgery. Methods Patients' DICM data of ankle via CT examinations were introduced into the MIMICS software to design the personalized guides. Two 2mm Kirschner wires were drilled with the help of the guides; the C-arm fluoroscopy was used to confirm the position of the wires before applying the cannulated screws. The patients who underwent ankle arthrodesis were divided into two groups. The experimental group adopted the 3D-printed personalized guides, while the control group received traditional method, i.e., drilling the Kirschner wires according to the surgeon's previous experience. The times of completing drilling the Kirschner wires to correct position were compared between the two groups. Regular follow-ups were conducted to statistically analyze the differences in the ankle fusion time and AOFAS scores between the two groups. Results 3D-printed personalized guides were successfully prepared. A total of 29 patients were enrolled, 15 in the experimental group and 14 in the control group. It took 2.2 ± 0.8 minutes to drill the Kirschner wires to correct position in the experimental group and 4.5 ± 1.6 minutes in the control group (p=0.001). No obvious complications occurred in the two groups during and after surgery. Postoperative radiographs confirmed bony fusion in all cases. There were no significant differences in the fusion time (p=0.82) and AOFAS scores at 1 year postoperatively between the two groups (p=0.55). Conclusions The application of 3D-printed personalized guide in assisting the accurate drilling of Kirschner wire in ankle arthrodesis can shorten the operation time and reduce the intraoperative radiation. This technique does not affect the surgical outcome. Trial Registration Number This study is registered on www.clinicaltrials.gov with NCT03626935.

Abstract
Background The purpose of this study was to compare clinical and radiological results of arthrodesis performed by the anterior approach and by the transfibular approach in ankle osteoarthritis. Methods Sixty patients underwent open arthrodesis (38 by the anterior approach and 22 by the transfibular approach). The visual analogue scale score and the American Orthopedic Foot and Ankle Society (AOFAS) score were examined clinically, and radiological examination was performed on the alignment of the lower extremity and bone union. Results Both groups showed significant improvement in AOFAS score (from 39.8 to 58.3 in the anterior approach group and from 44.5 to 60.7 in the transfibular approach group). There was no significant difference in AOFAS score at the last follow-up in both groups. The time to fusion was 13.5 weeks in the anterior approach group and 11.8 weeks in the transfibular approach group. Nonunion occurred in four cases in the anterior approach group and in one case in the transfibular approach group. Conclusions Ankle arthrodesis by the anterior approach and the transfibular approach showed comparably good clinical results.

Abstract
INTRODUCTION In advanced stages of ankle osteoarthritis (OA), ankle arthrodesis (AA) or total ankle arthroplasty (TAR) may be necessary. Our purpose is to compare AA and total ankle replacement for the surgical management of end stage ankle OA. SOURCES OF DATA We conducted a literature search of PubMed, Medline, CINAHL, Cochrane, Embase and Google Scholar databases using the terms 'ankle' in combination with 'OA', 'arthrodesis', 'arthroplasty', 'joint fusion', 'joint replacement'. Studies where treatment was exclusively total ankle replacement or AA were excluded. Treatment characteristics and outcome parameters (overall postoperative outcome and complication rate) were reviewed. AREAS OF AGREEMENT When counseling patients who are considering their options with regard to ankle arthritis treatment, surgeons should determine on an individual basis which procedure is more suitable. AREAS OF CONTROVERSY TAR has become an accepted treatment for end-stage OA, but revision rates for TAR are significant higher than for AA (odds ratio 2.28 95% confidence interval [CI], 1.63-3.19; P < 0.0001). GROWING POINTS The results of TAA are gradually improving, but the procedure cannot yet be recommended for the routine management of ankle OA. AREAS TIMELY FOR DEVELOPING RESEARCH Although there is some evidence to support TAR to conserve ankle motion and offer improved function and decreased pain with high satisfaction rates, revision rates for TAR are significantly higher than revision rates for AA. Proper patient selection should be better addressed in future studies for successful treatment of end-stage ankle OA. LEVEL OF EVIDENCE Systematic review, level III.

[PMID: 30356570 PMCID: PMC6189001 DOI: 10.1016/j.jshs.2016.01.012] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/17/2014] [Revised: 12/15/2014] [Accepted: 09/21/2015] [Indexed: 06/04/2023]
Abstract
BACKGROUND End-stage ankle arthritis impairs joint function and patients' mobility. Total ankle replacement is a surgical procedure to treat severe ankle arthritis. Salto Talaris Anatomic AnkleTM (STAA) was designed to mimic the normal ankle anatomy and flexion/extension of the ankle movement. The purpose of this study was to examine the effect of an STAA ankle replacement on ankle joint function and mechanics during gait. METHODS Five patients with end-stage unilateral ankle arthritis were recruited. Patients performed level walking in a laboratory setting on 2 occasions, prior to and 3 months after the STAA ankle surgeries. American Orthopedic Foot and Ankle Society (AOFAS) hindfoot score was obtained. A 12-camera motion capture system was used to perform walking analysis. Gait temporo-spatial parameters and ankle joint mechanics were evaluated. Paired Student's t tests and non-parametric Wilcoxon matched tests were performed to examine the differences in biomechanical variables between the pre- and post-surgery walking conditions. RESULTS Compared to the pre-surgical condition, at 3 months of post-STAA surgery, patients experienced greater improvement in AOFAS hindfoot score (p = 0.0001); the STAA ankle demonstrated a 31% increase in ankle joint excursion (p = 0.045), a 22% increase in ankle plantarflexor moment (p = 0.075), a 60% increase in ankle power absorption (p = 0.023), and a 68% increase in ankle power production (p = 0.039). Patients also demonstrated a 26% increase in walking speed (p = 0.005), a 20% increase in stride length (p = 0.013), a 15% decrease in double support time (p = 0.043), and a 5% decrease in total stance time (p = 0.055). CONCLUSION Three months after surgeries, the STAA patients experienced improvements in ankle function and gait parameters. The STAA ankle demonstrated improved ankle mechanics during daily activities such as walking.

Abstract
BACKGROUND In patients with painful ankle arthrodesis, the surgical treatment is challenging, and may include takedown of ankle arthrodesis and conversion to a total ankle replacement (TAR). This procedure is technically demanding given the altered anatomy after arthrodesis. Few studies have evaluated TAR in the setting of prior arthrodesis. QUESTIONS/PURPOSES (1) What intraoperative and perioperative complications were observed in patients who underwent conversion of an ankle arthrodesis to a TAR? (2) Was durable fixation achieved at short term, and what was the alignment of the components? (3) What subsequent surgical procedures were performed, including revisions? (4) What improvements were observed in pain, tibiotalar range of motion (ROM), and quality of life? METHODS Between January 2007 and December 2014, 18 patients with a painful ankle arthrodesis underwent conversion to TAR at our tertiary referral center. During this period, the indications for conversion of ankle arthrodesis to TAR were tibiotalar nonunion or malunion after attempted arthrodesis in patients who declined revision ankle arthrodesis. The goal of revision surgery was to help patients regain hindfoot mobility and to decrease pain. During the study period, all patients who met indications were treated with a conversion procedure. Of the 18 patients included, 14 were men and four were women. The mean age of the patients was 51 ± 7 years. The mean followup was 54 ± 27 months, with no loss to follow up observed. The initial ankle arthrodesis was performed 6 ± 3.5 years before conversion to TAR. In all patients, the conversion to TAR was performed using a nonconstrained cementless three-component prosthesis. Intraoperative and postoperative complications, revision procedures, and prosthesis component loosening were evaluated. Weightbearing radiographs were used to determine the angular alignment of the tibial and talar components using α/β/γ angles and to analyze the bone-implant interface. Osseointegration was defined as visible trabecular structures at the bone-implant interface without radiolucent lines. The criteria for radiographic loosening was defined as subsidence or migration of prosthesis components and/or a cystic lesion with a diameter at least 2 mm. Clinical assessment included pain evaluation, measurement of ankle ROM, and quality of life. RESULTS Two of the 18 patients sustained an intraoperative medial malleolar fracture. In three patients, delayed wound healing was observed. At latest followup, four patients had incomplete osseointegration (posterior quarter of the bone-prosthesis interface on the tibial side). None of the 18 patients had prosthesis loosening. In all patients, both components were neutrally aligned. Two patients had painful arthrofibrosis with reduced ROM, which we treated with an open arthrolysis and exchange of mobile-bearing inlay; one other patient is considering a revision for substantial tibial component medial tilt with collapse of the medial arch. At the latest followup, the mean dorsiflexion and plantar flexion were 8.5° ± 3° and 15° ± 5°, respectively. The mean visual analog scale (VAS) score decreased from 9 ± 0.8 to 1.7 ± 1.6 (p < 0.001). The Short Form Health Survey questionnaire (SF-36) physical and mental outcome scores improved from 34 ± 5 to 74 ± 11 (p < 0.001) and from 49 ± 4 to 75.5 ± 7 (p < 0.001). CONCLUSIONS Conversion of an ankle arthrodesis to a TAR is a technically challenging procedure. In this small series, it was associated with frequent complications including arthrofibrosis, and functional outcomes including postoperative ROM were lower than reported for primary TAR. However, pain and function did improve. Further studies are necessary to address long-term clinical and radiographic outcomes in this patient cohort. LEVEL OF EVIDENCE Level IV, therapeutic study.

Abstract
Ankle arthrodesis remains an important treatment option for patients with ankle arthritis. Many methods have been described; however, no consensus has been reached regarding the best technique to achieve both successful fusion and a good position for optimal foot mechanics. Furthermore, as arthroplasty has become more popular, preservation of the fibula to allow for future arthroplasty has become critical. The present report describes an innovative technique in which temporary external fixation at operative fixation is used, along with internal fixation, to achieve both an optimal foot position and high fusion rates, while maintaining the integrity of the fibula. Seventeen patients were identified who met the criteria for inclusion. Their medical records, including pre- and postoperative radiographs, were reviewed retrospectively. Preoperative and postoperative coronal and sagittal alignment was determined. All patients achieved successful fusion, although 1 (5.9%) patient experienced delayed union. The average tibial/talar ratio preoperatively was 21% (range 8% to 33%), demonstrating anterior subluxation. Postoperatively, this ratio improved to 33% (range 26% to 40%), approximating the normal anatomic ratio. Of the 17 patients, 5 (29.4%) had preoperative varus or valgus alignment of the talas >5°. All 5 cases were successfully corrected to within 2° of normal anatomic alignment. This technique allows the surgeon to achieve good visualization of the joint for preparation and to obtain the optimal position of the foot at arthrodesis without compromising the lateral column significance of the fibula. All patients obtained fusion, and minimal complications were associated with the use of this technique.

Abstract
Ankle arthrodesis is a common treatment used for patients with end-stage ankle arthritis (ESAA). The surgical goal of ankle arthrodesis is to obtain bony union between the tibia and talus with adequate alignment [slight valgus (0°-5°)], neutral dorsiflexion, and slight external rotation positions) in order to provide a pain-free plantigrade foot for weightbearing activities. There are many variations in operative technique including deferring approaches (open or arthroscopic) and differing fixation methods (internal or external fixation). Each technique has its advantage and disadvantages. Success of ankle arthrodesis can be dependent on several factors, including patient selection, surgeons’ skills, patient comorbidities, operative care, etc. However, from our experience, the majority of ESAA patients obtain successful clinical outcomes. This review aims to outline the indications and goals of arthrodesis for treatment of ESAA and discuss both open and arthroscopic ankle arthrodesis. A systematic step by step operative technique guide is presented for both the arthroscopic and open approaches including a postoperative protocol. We review the current evidence supporting each approach. The review finishes with a report of the most recent evidence of outcomes after both approaches and concerns regarding the development of hindfoot arthritis.

Hindfoot Arthrodesis with the Blade Plate: Increased Risk of Complications and Nonunion in a Complex Patient Population. Clin Orthop Relat Res 2016; 474:2280-99.

Abstract
BACKGROUND Previous hindfoot surgeries present a unique challenge to hindfoot arthrodesis, as the patients may have multiple incisions around the hindfoot. In high-risk patients with compromised soft tissues, a posterior approach can provide an alternative for a fresh soft tissue plane for the surgery. The use of a blade plate construct is widely accepted; however, there are limited data supporting the use of a posterior approach. QUESTIONS/PURPOSES We asked (1) what proportion of patients treated with this technique achieved osseous union; (2) what complications were observed; (3) were any patient-demographic or health-related factors associated with the likelihood that a patient would have a complication develop? METHODS Between December 2001 and July 2014, 42 patients received a posterior blade plate. During the period in question, indications for hindfoot arthrodesis using posterior blade fixation were subtalar osteoarthritis below an ankle fusion, malunion or nonunion, failed tibiotalocalcaneal arthrodesis attributable to nonunion of the tibiotalar and/or subtalar joint; or tibiotalar and subtalar osteoarthritis in patients with impaired bone or soft tissue quality (particularly if the soft tissue problem was anterior). During that period, all patients who met those indications were treated with a posterior blade plate. Forty (95%) were included in this study, and two were lost to followup before the 1-year minimum required by the study. Demographics (age, gender, BMI, smoking status, and comorbidities) and surgical data (indication, previous treatment, and additional procedures) were analyzed. Of the 40 patients included, 27 (68%) were male and 13 (33%) were female, with a median of two previous hindfoot or ankle surgeries (range, 0-9 surgeries). The mean age of the patients was 56 ± 13 years. Followup averaged 47 ± 28 months (range, 14-137 months). Twenty-eight of 40 (70%) patients had a tibiotalocalcaneal arthrodesis as a primary (n = 6), primary staged (n = 10), revision (n = 9), or revision staged (n = 3) procedure. Eleven of 40 patients (28%) underwent ankle arthrodesis (primary n = 7, revision n = 4). One of the 40 patients (3%) underwent tibiotalocalcaneal arthrodesis for a failed total ankle arthroplasty. Weightbearing radiographs were used to assess fusion. Osseous fusion was defined as visible trabecular bridging on the lateral and AP ankle views within 6 postoperative months. Delayed union was defined as osseous fusion occurring between 6 and 12 months. Nonunion was defined as no visible trabecular bridging at the latest followup (longer than 12 months). Clinic and surgery notes were reviewed for complications. Univariate analysis was performed to compare patient groups: patients with solid union versus nonunion, and patients with versus without complications. RESULTS Twenty-nine of 40 (73%) patients had osseous fusion within 6 postoperative months. Four of 40 (10%) patients had a delayed union between 6 and 12 months, and seven of the 40 (18%) patients had nonunions, which occurred in the ankle (n = 3), subtalar (n = 3), or both (n = 1) joints. There were 26 complications observed: 18 (69%) were considered major and eight (31%) were minor. With the numbers available, we did not identify any demographic or surgical factors associated with complications, delayed union, or nonunion. CONCLUSIONS The proportion of patients treated with a posterior blade plate hindfoot fusion who had delayed union or nonunion is greater than that reported for patients in other series who underwent primary hindfoot arthrodesis with other approaches, and the proportion of patients who had complications develop is high. Further studies are needed to address alternative approaches to achieve hindfoot fusion in patients with complex hindfoot problems. LEVEL OF EVIDENCE Level IV, therapeutic study.

Abstract
Bilateral ankle arthrodesis is seldom performed, and results concerning the outcome and satisfaction can only sparsely be found in published studies. We analyzed the data from 35 patients who had undergone bilateral ankle arthrodesis in the Swedish Ankle Registry using patient-reported generic and region-specific outcome measures. Of 36 talocrural arthrodeses and 34 tibio-talar-calcaneal arthrodeses, 6 ankles (9%) had undergone repeat arthrodesis because of nonunion. After a mean follow-up period of 47 ± 5 (range 12 to 194) months, the mean scores were as follows: self-reported foot and ankle score, 33 ± 10 (range 4 to 48); the EuroQol Group's EQ-5D™ score, 0.67 ± 0.28 (range -0.11 to 1), the EuroQol Group's visual analog scale score, 70 ± 19 (range 20 to 95), 36-item Short Form Health Survey (SF-36) physical domain, 39 ± 11 (range 16 to 58); and SF-36 mental domain, 54 ± 14 (range 17 to 71). Patients with rheumatoid arthritis seemed to have similar self-reported foot and ankle scores but possibly lower EQ-5D™ and SF-36 scores. Those with talocrural arthrodeses scored higher than did those with tibio-talar-calcaneal arthrodeses on the EQ5D™ and SF-36 questionnaires (p = .03 and p = .04). In 64 of 70 ankles (91%), the patients were satisfied or very satisfied with the outcome. In conclusion, we consider bilateral ankle arthrodesis to be a reasonable treatment for symptomatic hindfoot arthritis, with high postoperative mid-term satisfaction and satisfactory scores on the patient-reported generic and region-specific outcome measures, when no other treatment option is available.

Abstract
Supramalleolar osteotomy is a joint-preserving surgical treatment for patients with asymmetric valgus or varus ankle arthritis. The primary goal of the procedure is to realign the spatial relationship between the talus and tibia and thereby normalize joint loading within the ankle. Procedures to balance the soft tissues, as well as hindfoot osteotomy and arthrodesis, may also be necessary. Clinical studies of supramalleolar osteotomy demonstrate that correction of the altered biomechanics associated with asymmetric arthritis improves functional outcomes.

Abstract
BACKGROUND The purpose of this retrospective study is to analyze the effect of different variables on union rate and functional outcome in patients who underwent arthroscopic ankle fusion for end-stage arthritis of ankle. METHODS Clinical records and radiographs were reviewed to evaluate the variables that could predispose patients to non-union and poor functional outcome. Union and functional outcomes were correlated with different variables. RESULTS Fifty patients had arthroscopic ankle fusion on 52 ankles. The mean age at the time of surgery was 59.4 (27-80) years and mean length of follow up was 32.1 (8-78) months. Forty-eight out of 52 ankles (92.3%) achieved radiographic and clinical union. The average time to fusion was 12.2 (8-28) weeks. The time taken for union was significantly higher in smokers as compared to non-smokers (p<0.001). All the patients in this series who had non-union shared one common factor - neuromuscular imbalance. Age, gender, smoking, diabetes, steroid, bisphosphonates, neuropathy, frontal and sagittal plane alignment and tibial-axis-to-talus (T:T) ratio did not significantly affect the union rate and functional outcome. CONCLUSION Smokers should refrain from smoking before surgery and patients with neuromuscular problems may require more rigid fixation and a longer period of immobilization to achieve more consistent union rates.

Abstract
PURPOSE To review the outcome of 23 ankle arthrodeses using burring, curettage, multiple drilling, and fixation with 2 retrograde screws through a single lateral incision. METHODS Records of 22 consecutive patients aged 39 to 79 (mean, 62.4) years who underwent 23 ankle arthrodeses for end-stage ankle arthritis were reviewed. Through a single lateral incision, articular cartilage was removed using burring and curettage, and multiple holes were drilled using a Kirschner wire, followed by fixation with 2 retrograde screws. The resected distal fibula was fixed to the distal part of the talus and tibia. The position of the ankle and subtalar joint arthrosis was assessed by 2 orthopaedic specialists. Pre- and post-operative American Orthopaedic Foot and Ankle Society (AOFAS) scores were evaluated. RESULTS The mean operating time was 122 minutes. The mean follow-up period was 41 months. The mean postoperative ankle alignment was suboptimal: 2.7º varus, 6.7º plantar flexion, and 2.9º internal rotation. The mean AOFAS score improved from 30 to 71 (p<0.01). The postoperative varus ankle alignment was not associated with the AOFAS score (r= -0.13, p=0.569). Of the 23 cases, one was nonunion and 22 achieved bone union after a mean of 5.4 (range, 2-16) months; 3 of them were delayed union. Despite bone union, 7 patients complained of persistent pain; 4 of them had progressive arthrosis of the adjacent subtalar joints (n=2) or subtalar and talonavicular joints (n=2). CONCLUSION Ankle arthrodesis using burring, curettage, multiple drilling, and fixation with 2 retrograde screws achieved a high union rate and acceptable functional score without serious complications.

Abstract
Aims This retrospective cohort study compared the results of vascularised and non-vascularised anterior sliding tibial grafts for the treatment of osteoarthritis (OA)of the ankle secondary to osteonecrosis of the talus. Patients and Methods We reviewed the clinical and radiological outcomes of 27 patients who underwent arthrodesis with either vascularised or non-vascularised (conventional) grafts, comparing the outcomes (clinical scores, proportion with successful union and time to union) between the two groups. The clinical outcome was assessed using the Mazur and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores. The mean follow-up was 35 months (24 to 68). Results The mean outcome scores increased significantly in both groups. In the vascularised graft group, the mean Mazur score improved from 36.9 to 74.6 and the mean AOFAS scale improved from 49.6 to 80.1. In the conventional arthrodesis group, the mean Mazur score improved from 35.5 to 65 and the mean AOFAS scale from 49.2 to 67.6. Complete fusion was achieved in 13 patients (76%) in the vascularised group, but only four (40%) in the conventional group. The clinical outcomes and proportion achieving union were significantly better in the vascularised group compared with the conventional arthrodesis group, although time to union was similar in the two groups. Take home message: Vascularised sliding tibial grafts may be used to achieve arthrodesis in patients with OA of the ankle secondary to osteonecrosis of the talus.

Abstract
PURPOSE The purpose of this study was to identify the most reliable classification system for clinical outcome studies to categorize post-traumatic-fracture-osteoarthritis. METHODS A total of 118 orthopaedic surgeons and residents-gathered in the Ankle Platform Study Collaborative Science of Variation Group-evaluated 128 anteroposterior and lateral radiographs of patients after a bi- or trimalleolar ankle fracture on a Web-based platform in order to rate post-traumatic osteoarthritis according to the classification systems coined by (1) van Dijk, (2) Kellgren, and (3) Takakura. Reliability was evaluated with the use of the Siegel and Castellan's multirater kappa measure. Differences between classification systems were compared using the two-sample Z-test. RESULTS Interobserver agreement of surgeons who participated in the survey was fair for the van Dijk osteoarthritis scale (k = 0.24), and poor for the Takakura (k = 0.19) and the Kellgren systems (k = 0.18) according to the categorical rating of Landis and Koch. This difference in one categorical rating was found to be significant (p < 0.001, CI 0.046-0.053) with the high numbers of observers and cases available. CONCLUSIONS This study documents fair interobserver agreement for the van Dijk osteoarthritis scale, and poor interobserver agreement for the Takakura and Kellgren osteoarthritis classification systems. Because of the low interobserver agreement for the van Dijk, Kellgren, and Takakura classification systems, those systems cannot be used for clinical decision-making. LEVEL OF EVIDENCE Development of diagnostic criteria on basis of consecutive patients, Level II.

Abstract
BACKGROUND The objective of this study was to identify factors influencing operative outcomes in straightforward, uncomplicated open ankle fusions. METHODS We reviewed all primary open ankle fusions conducted at 1 institution over an 11-year period to identify straightforward, uncomplicated open ankle fusions. Inclusion required a minimum of 6 months follow-up. Patients were excluded for neuropathic arthropathy, insensate limb, failed total ankle replacement, simultaneous arthrodesis of the subtalar joint, or fusions performed within 1 year of injury to salvage failed fixation and painful function due to (1) open fractures, (2) segmental bone loss greater than 1 cm, (3) infection, or (4) talar body fractures. The primary outcome variable was radiographic union at 6 months. Other operative complications were analyzed as secondary outcomes. Five hundred twenty-eight ankle fusion surgeries were performed on 440 patients at 1 institution during the study period. Two hundred fifteen surgeries met inclusion/exclusion eligibility criteria for uncomplicated open ankle fusions. RESULTS The overall union rate was 91%. In this cohort of uncomplicated open ankle fusions, bivariate analysis over a broad range of potential factors and further focused multivariate analysis found that nonunion was more than 3 times more likely to occur after previous subtalar fusion, and 2 times more likely to occur in patients with preoperative varus ankle alignment. The rate of reoperation was 19%, with nonunion revision as the leading reason, followed by hardware removal and incision and drainage for presumed infection. Diabetes was not a significant risk factor of either deep or superficial infection. CONCLUSION Open ankle fusion failed in 9% of uncomplicated ankles with arthritis. Patients who had an open ankle fusion done after previous subtalar joint fusion, as well as those who had preoperative varus ankle alignment, had a significantly higher rate of nonunion. LEVEL OF EVIDENCE Level III, retrospective comparative study.
