Alignment of CCI total ankle replacements in relation to midterm functional outcome and complication incidence

Abstract

Background Total ankle arthroplasty is increasingly used as a treatment for end stage ankle arthropathy. The aim of this study was to report the mid-term clinical function and survival results of Ceramic Coated Implant (CCI) ankle replacements and assess the association between the alignment of the CCI total ankle replacements and early functional outcome and complication incidence. Methods Data of 61 patients, who received 65 CCI implants between 2010 and 2016, were obtained from a prospectively documented database. Mean follow-up time was 85.2 months (range 27–99 months). Clinical function was assessed with AOFAS questionnaire and passive range of motion (ROM). Survival analysis and elaborate radiographic analysis was performed. Furthermore, complications and reoperations were recorded for all patients. Results Progression in ROM was most seen in the first 10 months from 21.8 degrees of passive range of motion preoperative to 27.6 degrees postoperative (p < 0.001), while the mean AOFAS gradually increased during follow-up postoperative from a mean of 40.9 points preoperative to an average of 82.5 but shows a small decline towards the end of follow-up (p < 0.001). During follow-up we recorded 8 failures (12.3%) resulting in a Kaplan-Meier survival analysis of 87.7% with a median follow-up of 85.2 months. Conclusion We observed excellent clinical results and survival after TAA with the CCI implant with only a low mid-term complication rate. Level of evidence Level III, prospective cohort study.

The Effect of Tibiotalar Joint Line Level Alterations on Tibiotalar Range of Motion Following Total Ankle Arthroplasty

“…1,4,24,33 Additionally, multiple studies have reported that the progression of ROM is observed within the first year postoperatively and that patients should expect to plateau and maintain their 1-year postoperative degree of motion for the life of their implant. 1,20 TAA has been shown to improve gait function with both pre-and postoperative ROM predictive of overall postoperative gait function. 5,6,15 Ankle ROM following TAA is positively correlated with multiple disease-specific and generic health-related quality of life patient-reported outcome measures (PROMs).…”
