Overview
Causes
Osteoarthritis often affects multiple members of the same family, suggesting that there is hereditary susceptibility to this condition. A 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. Randomized, controlled studies have shown a 40% reduction in joint degeneration if Tetracycline derivative antibiotics are taken consistently over time.
Obesity may contribute to osteoarthritis of the knee.[1][2][3]
Leg-length inequality > 1 cm is associated with osteoarthritis of the knee.[4]
