Category: Ankle Arthritis Introduction/Purpose: Ankle arthrodesis remains a prominent treatment choice for ankle arthritis in a majority of patients. Long term studies have shown a compensatory development of ipsilateral adjacent joint arthritis after ankle arthrodesis, and some patients who receive an ankle arthrodesis develop pain in surrounding joints, or even at the fusion site. As total ankle arthroplasty (TAA) design, instrumentation, and techniques have improved, the use of total ankle arthroplasty has become more widespread. Very few studies have been published on conversion of ankle arthrodesis to ankle arthroplasty, but they have shown improved function and patient-related outcome scores. The purpose of this study was to assess the radiographic, clinical, and patient-reported outcomes of patients undergoing ankle arthroplasty after conversion from a CT-confirmed ankle arthrodesis. Methods: This was a retrospective cohort study of patients with previous CT-confirmed ankle arthrodesis who underwent conversion to total ankle arthroplasty. Minimum follow up was 1 year. Nonunions of ankle arthrodesis were excluded. AOFAS ankle-hindfoot score, foot function index (FFI), pain, revision surgeries, complications, and patient demographics were assessed. Radiographs prior to TAA, and at latest follow-up were also reviewed. Results: 10 patients were included in the study with an average age of 54.5 years. No implants had to be revised. 1/10 (10%) patients had to undergo secondary surgery for heterotopic ossification removal. The same patient had to undergo another subsequent surgery for posterior ankle decompression. 2/10 (20%) patients had a mild talar subsidence of the TAA at latest follow-up, with no patients having tibial subsidence. Talar osteolysis was noticed in 2 patients (20%) at latest follow-up, with no patients having tibial osteolysis. Only one patient (10%) was noted to have a mild valgus alignment of TAA with no varus malalignments. All radiographic changes noted were clinically asymptomatic. The average AOFAS total score was 58 (range 23,89). The mean FFI total score was 41.9 (range 0,90). Conclusion: Conversion of ankle fusion to TAA is a challenging operation but can be a viable option for patients with ongoing pain after an ankle arthrodesis. We noted low revision rates and few complications at 1 year.

Ankle Arthroplasty

Category: Ankle Arthritis Introduction/Purpose: Ankle arthrodesis is commonly performed for patients with end stage ankle arthritis. However, with improvements in long-term outcomes following total ankle arthroplasty it is possible that rates of ankle arthrodesis will decrease as utilization of ankle arthroplasty increases. The purpose of this study is to assess the current and future trends of ankle arthrodesis utilization. Methods: National Inpatient Sample (NIS) data from 1997-2014 was used to identify trends in the utilization of ankle arthrodesis. United States Census Bureau data from 1997-2014 was used to identify historical population data and future population estimates. A linear regression model was created using Mathematica v11.3 to project future demand for ankle arthrodesis. The data was stratified to show past and future trends based on gender and age. Results: The overall utilization rate of ankle arthrodesis remained relatively constant from 5897 procedures in 1997 to 5330 procedures in 2014. The overall demand for ankle arthrodesis is expected to increase slightly by 15 percent with 6141 procedures projected in 2045. Stratified by age groups, the number of procedures is predicted to decrease by 75% in ages 18-44 and 6% in ages 45-64, and predicted to increase by 133% in ages 65-84 by 2045. Stratified by gender, ankle arthrodesis is predicted to increase by 47% in males and decrease by 14% in females in 2045. Conclusion: Based on our projection model, the rate of ankle arthrodesis is predicted to stay relatively stable overall but decrease in younger populations. A projected increase in total ankle arthroplasty will likely contribute to decreased utilization of ankle arthrodesis. However, ankle arthrodesis will still be a valuable tool in the surgeon’s armamentarium to treat ankle arthritis.

Abstract Ankle arthrodesis and total ankle arthroplasty are the two primary surgeries for treatment of end-stage degenerative ankle arthritis. The biomechanical effects of them on the inner foot are insufficient to identify which is superior. This study compared biomechanical parameters among a foot treated by ankle arthrodesis, a foot treated by total ankle arthroplasty, and an intact foot using computational analysis. Validated finite element models of the three feet were developed and used to simulate the stance phase of gait. The results showed total ankle arthroplasty provides a more stable plantar pressure distribution than ankle arthrodesis. The highest contact pressure, 3.17 MPa, occurred in the medial cuneonavicular joint in the total ankle arthroplasty foot. Neither of the surgeries resulted in contact pressure increase in the subtalar joint. The peak stress in the metatarsal bones was increased in both surgical models, especially the second and third metatarsals. This study enables us to get visual to the biomechanics inside of an intact foot, and feet treated by total ankle arthroplasty and ankle arthrodesis during walking.
