Replacement Design

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

Introduction: Auto-generated 3-dimensional (3D) measurements based on weightbearing cone-beam computed tomography (CT) scan technology may allow for a more accurate hind- and midfoot assessment. The current study evaluated the reliability and clinical relevance of such measurements in patients with posttraumatic end-stage ankle osteoarthritis. Methods: Seventy-two patients treated at our institution for posttraumatic end-stage ankle osteoarthritis, with available weightbearing conventional radiographs and a cone-beam CT scan, were analyzed. Twenty healthy individuals aged between 40 and 70 years served as controls. Seven variables were measured on weightbearing conventional radiographs (2D) and compared to 3D measurements that were based on reconstructions from weightbearing cone-beam CT scans. The reliability of each measurement was calculated and subgroups formed according to commonly observed deformities. Results: Inter- and intraobserver reliability was superior for 3D compared to 2D measurements. The accuracy of 3D measurements performed on osteoarthritic ankles was similar to 3D measurements performed on healthy individuals. Thirty-three of the 72 included patients (46%) evidenced an inframalleolar compensation of a supramalleolar/intra-articular ankle deformity (78% = varus compensation; 22% = valgus compensation), whereas 24 of those 72 patients (33%) showed no compensation or a further increase of a supramalleolar/intra-articular ankle deformity (67% = varus deformity; 33% = valgus deformity). Conclusion: Auto-generated 3D measurements of the hind- and midfoot were found to be reliable in both healthy individuals and patients with posttraumatic end-stage ankle osteoarthritis. Such measurements may be crucial for a detailed understanding of the location and extent of hindfoot deformities, possibly impacting decision making in the treatment of end-stage ankle osteoarthritis. Level of Evidence: Level III, comparative study.

Background: Significant ankle arthritis results in functional limitations and patient morbidity. There is a need to measure symptoms and the impact of interventions on patient’s quality of life using valid and reliable patient-reported measurement instruments. The objective of this research was to validate the Ankle Osteoarthritis Scale instrument in the preoperative setting using factor analysis, item response theory, and differential item function methods. Methods: This research is based on secondary analysis of patients scheduled for ankle arthrodesis or total ankle replacement in Vancouver, Canada. Participants completed the instrument between September 2014 and August 2017. Item response theory was used to estimate item difficulty and discrimination parameters, controlling for study participants’ underlying level of ankle function. Differential item function was examined for sex, age group, and surgery. There were 88 participants. Results: Modification indices suggested that item 10, “walking around the house,” would better fit the pain domain rather than the disability domain. Items in the pain domain displayed a range of discrimination and difficulty. Items in the disability domain exhibited a range of discrimination, though the disability domain had low difficulty. Differential item functioning for sex, age group, and ankle arthrodesis or total ankle replacement appeared to be ignorable. Conclusion: This evaluation of the Ankle Osteoarthritis Scale found the instrument to be a strong measure of the effect of pain and dysfunction among patients with end-stage ankle arthritis, even when removing items 7 and 8, supporting its prior use in numerous clinical studies. Level of Evidence: Level II, prospective comparative study.

Background: We examined four commonly used scores, the SF-36, the Ankle Osteoarthritis Scale (AOS), the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle Hindfoot Score, and the Foot Function Index (FFI) to determine their responsiveness and validity. Methods: Patients with end stage ankle arthritis were recruited into a prospective multicenter cohort study and baseline and one year outcome scores were compared. The Standardized Response Mean and Effect Size for the AOS, AOFAS, and FFI were calculated and the three region- or disease-specific scores were compared with the SF-36 to determine their criterion validity. Results: All four scores showed acceptable responsiveness, and when using the validated SF-36 as the standard the three region or disease specific scores all showed similar criterion validity. Conclusion: All four scores are responsive and can be considered for use in this population. The objective component of the AOFAS Ankle Hindfoot Score may make it harder to perform than the other three scores which have subjective components only, and as yet its objective component has not been shown to demonstrate reliability. We recommend use of a purely subjective score such as the Ankle Osteoarthritis Scale or Foot Function Index as the region- or disease-specific score of choice in this population. As the SF-36 shows acceptable responsiveness, using it alone could also be considered. Level of Evidence: II, Prospective Comparative Study

Category: Ankle, Ankle Arthritis Introduction/Purpose: Over the last few decades, total ankle replacement (TAR) emerged as a reliable treatment option in end-stage ankle osteoarthritis (OA) while preserving motion and physiological load. The Cadence™ prosthesis, manufactured by Integra LifeSciences, is a two-component, fixed-bearing implant with minimal tibial and talar resection and has been in clinical use since June 2016. The purpose of this study is to assess the two-year validated clinical outcome scores and radiological parameters of the Cadence™ prosthesis at our hospital. Methods: Thirty-one consecutive patients who received the Cadence™ prosthesis between June 2016 and December 31st, 2016 were enrolled. All patients who underwent a primary TAR with the Cadence™ prosthesis and who had at least two years follow- up were included. All surgeries were performed by a single surgeon with experience in total ankle arthroplasty. At the yearly clinical evaluation, patients were administered the Ankle Osteoarthritis Scale (AOS) and the Short Form Health Survey (SF-36), and their radiological outcomes pre and post-surgery were assessed. Results: Thirty-one patients fulfilled the inclusion criteria. Forty ancillary procedures were performed on twenty-four TAR’s. Radiological analyses showed preoperative talar sagittal translation with 25 anterior, 2 posterior, and 4 neutral. Sagittal translation decreased from an average 3.11 mm to 1.0 mm. Eleven ankles had a perioperative talar Varus and Valgus deformity that was corrected, with neutral alignment in all. At the two-year clinic visit, x-rays showed no lucencies or stress fractures and none of the ankles required revision of metal components. The pre and post-operative pain and disability scores displayed major improvement wherein AOS pain scores decreased -20.28 ± 14.34 points from an average of 47.86 points while AOS disability scores decreased -32.11 ± 22.70 from an average of 57.15 points. Conclusion: The overall outcome of the total ankle arthroplasty with the Cadence™ prosthesis showed excellent clinical and radiological outcomes. Compelling clinical evidence shows that the quality of life, functional measures, and pain in patients suffering from end-stage arthritis significantly improved following surgery with the Cadence™ total ankle replacement system. The semi- constrained design of this two-component implant and utilization of biased polyethylene inserts allowed for correction of the talus in both the sagittal (talar anterior / posterior translation) and coronal planes (talar varus / valgus).
