ABSTRACT
This study aimed to investigate the intermediate-term efficacy of nonosteotomy approaches
in the treatment of early to intermediate stage ankle osteoarthritis (OA). Forty-two
patients received treatment for early to intermediate stage ankle osteoarthritis with
nonosteotomy approaches were reviewed. The surgical satisfaction was evaluated at
1 year after surgery and the last follow-up period; the American Orthopaedic Foot
and Ankle Society (AOFAS) scale and Visual Analog Scale (VAS) were employed for the
evaluation of function and pain, respectively, and the stage of ankle osteoarthritis
was determined. At 1 year surgery and the last follow-up period, the surgical satisfaction
was 37 (88.1%) and 35 (83.3%), respectively, and the favorable function was noted
in 34 (80.9%) and 32 (76.2%), respectively. The AOFAS score significantly increased
from 50.62 ± 10.81 (range 30-60) before surgery to 81.43 ± 12.00 (range 75-95) at
1 year after surgery (p < .0001) and 79.67 ± 10.34 (range 70-96) at the last follow-up period (p < .0001 vs before surgery; p = .107 vs 1 year). The VAS score reduced from 5.07 ± 1.57 (range 4-7) before surgery
to 1.97 ± 1.41 (range 0-3) at 1 year (p < .0001) and 1.80 ± 1.15 (range 0-3) at the last follow-up period (p < .0001 vs before surgery; p = .265 vs 1 year). Moreover, the AOFAS score and VAS score in patients with ankle
osteoarthritis at different stages were improved significantly after surgery (p < .0001). Intermediate-term follow-up period shows that nonosteotomy approaches are
able to relieve pain and improve postoperative function in the treatment of early
to intermediate stage ankle osteoarthritis; the improvement determined according to
imaging examination is not completely consistent with that determined based on clinical
function.
