“…Despite this disparity in contact forces, ankle arthritis is 9 times less common than hip or knee arthritis as the ankle is a more constrained joint. 1,2 Affected patients, however, have greater perceived disability and functional scores comparable to patients with significant hip arthritis. 3,4 Posttraumatic ankle arthritis accounts for 70% to 80% of patients.…”

Background Surgical management of end-stage ankle arthritis consists of either ankle arthrodesis (AA) or total ankle replacement (TAR). The purpose of this study was to evaluate utilization trends in TAR and AA and compare cost and complications. Methods Medicare patients with the diagnosis of ankle arthritis were reviewed. Patients undergoing surgical intervention were split into AA and TAR groups, which were evaluated for trends as well as postoperative complications, revision rates, and procedure cost. Results A total of 673 789 patients were identified with ankle arthritis. A total of 19 120 patients underwent AA and 9059 underwent TAR. While rates of AA remained relatively constant, even decreasing, with 2080 performed in 2005 and 1823 performed in 2014, TAR rates nearly quadrupled. Average cost associated with TAR was $12559.12 compared with $6962.99 for AA ( P < .001). Overall complication rates were 24.9% in the AA group with a 16.5% revision rate compared with 15.1% and 11.0%, respectively, in the TAR group ( P < .001). Patients younger than 65 years had both higher complication and revision rates. Discussion TAR has become an increasingly popular option for the management of end-stage ankle arthritis. In our study, TAR demonstrated both lower revision and complication rates than AA. However, TAR represents a more expensive treatment option. Levels of Evidence: Level III: Retrospective comparative study

“…8,36 If the symptoms progress despite nonoperative treatment, surgery is offered and is most often ankle arthrodesis (AA) or total ankle replacement (TAR). 3,4,22 Given the disability of ankle arthritis on patients' quality of life, there is a need to measure symptom improvement and the impact of operative interventions on quality of life using valid and reliable patient-reported measurement instruments. 4 Published studies evaluating ESAA effects and treatment options have used the Ankle Osteoarthritis Scale (AOS) as a patient-reported outcome measure for quality of life (QoL).…”

Validation of the Ankle Osteoarthritis Scale Instrument for Preoperative Evaluation of End-Stage Ankle Arthritis Patients Using Item Response Theory

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.
