femoroacetabular impingement in asymptomatic subjects and the
development of osteoarthritis of the hip

Περίληψη:
We retrospectively examined the long-term outcome of 96 asymptomatic
hips in 96 patients with a mean age of 49.3 years (16 to 65) who had
radiological evidence of femoroacetabular impingement. When surveillance
commenced there were 17, 34, and 45 hips with cam, pincer, and mixed
impingement, respectively. Overall, 79 hips (82.3%) remained free of
osteoarthritis for a mean of 18.5 years (10 to 40). In contrast, 17 hips
(17.7%) developed osteoarthritis at a mean of 12 years (2 to 28). No
statistically significant difference was found in the rates of
development of osteoarthritis among the three groups (p = 0.43).
Regression analysis showed that only the presence of idiopathic
osteoarthritis of the contralateral diseased hip was predictive of
development of osteoarthritis on the asymptomatic side (p = 0.039).
We conclude that a substantial proportion of hips with femoroacetabular
impingement may not develop osteoarthritis in the long-term.
Accordingly, in the absence of symptoms, prophylactic surgical treatment
is not warranted.
