Osteoarthritis often affects multiple members of the same family, suggesting that there is hereditary susceptiblity to this condition.
GenesA number of studies have shown that there is a greater prevalence of the disease between siblings and especially identical twins, indicating a hereditary basis. Up to 60% of OA cases are thought to result from genetic factors.
Researchers are also investigating the possibility of allergies, infections, or fungi as a cause. There is some evidence that allergies, whether fungal, infectious or systemically induced, may be a significant contributing factor to the appearance of osteoarthritis in a synovial sac. |
