Abstract
Of 111 primary ankle ligament arthroplasties (modified Evans procedure) performed between 1983 and 1994, we were able to identify 89 patients (94 ankles) for follow-up. All were under 50 years of age. Two had died and one refused to co-operate; 86 patients (91 ankles) were therefore reviewed, 25 by telephone and the remainder by clinical examination with all but three also undergoing radiological review. Of the 91 ankles, 70 had no or very mild pain and 72 had no or rare episodes of instability and when considered together only 59 (65%) had no or mild pain and minimal instability. The results were supported by the Karlsson grading system. Clinical examination showed that 17 of the 66 ankles examined had increased inversion, while 21 had some limitation of inversion. Early degenerative changes were seen in 11 ankles, although only four had subtalar changes. These results show that this procedure does not give universally good clinical results. Patient satisfaction, however, was high with 97.7% being willing to undergo the same procedure if their other ankle became similarly affected.
