The objective of this prospective study was to determine clinical and radio
logical results 2 years after ankle fractures and to compare them with preo
perative arthroscopic findings. Of 135 consecutive patients undergoing oste
osynthetic treatment, 128 (type A, 2; type B, 97; type C, 29) were reviewed
2 years later. The Kitaokascore for functional and clinical rating and the
Kannusscore for radiological rating were used. Initial cartilaginous lesio
ns localized on the medial malleolus led to poor clinical ratings (P < 0.01
) and cartilaginous lesions of the pilon tibiale and talus caused poor radi
ological results (P < 0.032 and P < 0.046). After rupture of the deltoid li
gament, more pain was observed (P < 0.038). Rupture of the syndesmosis, how
ever, did not affect the outcome. Clinical outcome was poor among the 30- t
o 65-year-old patients. The clinical and radiological outcome of women was
poorer (P < 0.018 and P < 0.046) than for men. The older the patients, the
more radiological signs of arthritis were found. The outcome of ankle fract
ure seems to correlate significantly with the nature, dimension and localiz
ation of fracture-associated cartilaginous and ligament lesions. Age and se
x also seem to play a significant role in the outcome.
