MONDAY, July 25 (HealthDay News) -- Children and teens with
abnormal development of the long bone between the pelvis and knee
from playing high-intensity sports, such as soccer and basketball,
are at greater risk for osteoarthritis of the hip, according to a
Swiss researchers explained that deformities of the top of that
bone -- known as the femur -- leads to reduced rotation and pain
during movement among young competitive athletes. This may explain
why athletes are more likely to develop osteoarthritis than more
sedentary individuals, according to Dr. Klaus Siebenrock, from the
University of Bern in Switzerland.
The researchers examined the physical condition and range of
motion of 72 hips in 37 male professional basketball players and 76
hips in 38 control participants who had not participated in
The study showed that men and teens that had played in an elite
basketball club since the age of 8 were more likely to have
osteoarthritis of the hip than in those who did not take part in
regular sports. The athletes, the researchers found, had femur
deformities causing their thighbone to have abnormal contact with
their hip socket.
As a result, they had reduced internal hip rotation and painful
hip movements. The study's authors noted these differences got
worse during late adolescence.
Overall, the researchers found, athletes were 10 times more
likely to have impaired hip function than those who did not play
