Clinical Evaluation and Radiographic Assessment of Bone Lysis of the AES Total Ankle Replacement

Abstract: Although functional outcomes were comparable to the other mobile TAR in the literature, bone lysis with the AES prosthesis was more frequent with risk of subsidence. We therefore stopped implantation of this prosthesis and recommend preventive grafting for severe lysis.

“…Radiographs were analyzed successively by the operators and by two independent surgeons (FG and JRL). In case of disagreement, the most unfavorable assessment was adopted [3]. In seven patients, bone cysts were already visible on the preoperative radiographs and were not considered pathologic (Figs.…”

“…A radiolucent line was considered pathologic if it was more than 2 mm thick or if it was observed globally across a prosthetic component [29,48,51]. An osteolytic cyst was defined as a hypodense zone greater than 5 mm in diameter with no inner bone trabeculae but with peripheral sclerosis that was not present preoperatively [3]. Radiographs were analyzed successively by the operators and by two independent surgeons (FG and JRL).…”

“…Failure causes include aseptic loosening, subsidence, cysts formation, peri-prosthetic and polyethylene fracture (Conti and Wong, 2001;Besse et al, 2009;Bonnin et al, 2011;Labek et al, 2011;Brunner et al, 2013).…”

“…They reported rates of revision per 100 observed component years to be 1.29 for THR, 1.26 for TKR and 3.29 for TAR. Cumulatively seen this corresponds to revision rates that are slightly higher than 10% after 10 years for THR and TKR, whereas revision surgery is expected by approximately one-third of all TAR patients after 10 years (Fevang et al 2007;Besse et al 2009;Easley et al 2011;Brunner et al 2013;Zaidi et al 2013).…”
