“…[1][2][3][4]6,[9][10][11]15 We created cylindrical-type prostheses on the basis of the results of friction and wear experiments using a simple cylindrical axis with an ankle simulator. 14 Our prostheses were made without a lateral facet for ankles that receive repeated trauma, to prevent loosening caused by additional trauma.…”

Ankle arthroplasties using metal and polyethylene prostheses were done on 28 patients (30 ankles) with painful osteoarthritis or rheumatoid arthritis between 1975 and 1980. Significant loosening and subsidence of the metal prostheses occurred in most patients, and ceramic prostheses were introduced in 1980. Ceramic prostheses with or without cement were used to replace 60 ankles in 56 patients with painful arthritis between 1980 and 1991. Revision surgery was required for five patients (five ankles) during the followup period (mean, 12 years 6 months). Loosening and subsidence of the prostheses were seen in 50% of patients within 5 years after the index procedure. As a result, a new design of bead-formed alumina coated with hydroxyapatite was used. A tibial prosthesis fixed to the posterior cortex of the tibia with a screw was used from 1991. These new ceramic prostheses were used to replace 70 ankles in 62 patients between 1991 and 2000. Thirty-six patients (36 ankles) with a mean age of 71 years (range, 50-87 years) had osteoarthritis, and 26 patients (31 ankles) with a mean age of 60 years (range, 41-76 years) had rheumatoid arthritis. During followup, with an average of 5 years 2 months, three patients (three ankles) required revision surgery (one for infection, two for talar necrosis). Overall results for patients with osteoarthritis were excellent in 21 ankles, good in 10 ankles, fair in two, ankles and poor in zero ankles. Results in patients with rheumatoid arthritis were excellent in five ankles, good in 16 ankles, fair in three ankles, and poor in two. In the intermediate study, 29 patients (31 ankles; 91.2%) with osteoarthritis and 19 patients (21 ankles; 76.9%) with rheumatoid arthritis were satisfied with the short-time results of arthroplasty.

“…Obwohl in den letzten Jahren ermutigende kurz-und mittelfristige Ergebnisse implantierter Prothesen des oberen Sprunggelenks (OSG) publiziert worden sind [3,6,13,17,18,24], bleibt die OSG-Arthrodese bei jungen und aktiven Patienten mit hohen Belastungsansprüchen, bei Patienten mit rheumatischen Erkrankungen und vor allem bei Patienten mit groben Fehlstellungen im Sprunggelenk die Therapie der Wahl [5,8,10,23,25,26].…”

“…In spite of the fact that, recently, encouraging shortand medium-term results of total ankle arthroplasties have been reported [3,6,13,17,18,24], the ankle arthrodesis remains the treatment of choice for young and active patients with high demands, for rheumatoid patients, and for patients with a marked malalignment of the ankle [5,8,10,23,25,26].…”

20 arthrodeses in 19 patients were followed up for an average of 39 months (12-69 months). All arthrodeses were fused. In one patient a fibular pseudarthrosis was encountered. All arthrodeses healed in a correct position but one that consolidated with a pes equinus of 3 degrees . The average AOFAS (American Orthopedic Foot and Ankle Society) hindfoot score reached 78.5 points (40-86 points). A marked reduction of symptoms and satisfactory function were reported postoperatively by all patients. All would be willing to undergo surgery again.

“…[1,2,4] AP ankle malalignment is one possible cause of premature implant failure, and unfavorable mechanical effects of AP implant malpositioning have been described in cadaver-based experimental studies. [5,7] However, one of the reasons this problem has not yet been well studied is because of a lack of reliable means to assess AP ankle alignment.…”

Ankle Alignment on Lateral Radiographs. Part 1: Sensitivity of Measures to Perturbations of Ankle Positioning

Background-In ankles with end-stage osteoarthritis or with total ankle replacement (TAR), radiographic landmarks based on joint surface morphology are usually obscured and thus inadequate for radiographic measurement. Furthermore, because of difficulty in reproducibly positioning the ankle for a standing radiograph, any radiographic measure to accurately describe ankle alignment needs to tolerate perturbations of ankle positioning in clinical radiographs. To identify a radiographic measure of antero-posterior (AP) tibial-talar alignment that meets those requirements, three candidate measures were compared by means of sensitivity to perturbations of ankle positioning.
