ABSTRACT
Two consecutive
series of patients who had cementless, porous-coated, congruent-contact,
mobile-bearing total ankle replacements were evaluated during
a 20-year interval using the New Jersey Orhopaedic Hospital
(NJOH) ankle scoring scale to determine clinical outcome and
overall implant survivorship with revision as an end point.
The initial series of 38 patients (40 ankle replacements)
using a shallow-sulcus design had diagnoses of: OA, seven
(17.5%); RA, nine (22.5%); PTA, 21 (52.5%); and failed fusion
three (7.5%). Clinical results after 2 to 20 years, (mean,
12 years) were 28 (70%) good to excellent, two (5%) fair,
and 10 (25%) poor. Postoperative ankle motion ranged from
10? to 47? total arc (mean, 25? total arc). The 20-year overall
survivorship for the shallow-sulcus design was 74.2%. A second
series of 74 patients (75 ankle replacements) using a deep-sulcus
design had diagnoses of: OA, eight (11%); RA, nine (12%);
ON, three (4%); and PTA, 55 (73%). Clinical results after
2 to 12 years, (mean 5 years) were 66 (88%) good to excellent,
four (5%) fair, and five (7%) poor. Postoperative ankle motion
ranged from 10? to 50? total arc (mean, 29? total arc). The
12-year overall survivorship for the deep-sulcus design was
92%
