One hundred twenty probands with primary osteoarthrosis of the hip or knee
were examined prospectively; there were 194 controls. In addition, 193
patients with hip or knee arthrosis were examined retrospectively.
Restriction of rotation on physical examination accurately differentiated
arthrotic hips from normal ones. Among women, 38% of the controls and 49%
of the probands had Heberden nodes (P more than .1). Their prevalence
increased with age. Individuals with multiple arthrosis joints were not
older than those with single joint involvement, and they has a similar
prevalence of nodes. Of the probands, 14% had arthrosis of both the knee
and hip. Of those with bilateral hip arthrosis, 33% had knee arthrosis as
well. Heberden nodes are unrelated to osteoarthrosis of the knee or hip.
Knee and hip arthroses frequently occur together and remain confined to the
initially affected joints. They may have a common cause.
