Osteoarthritis and osteoporosis both are serious conditions. Osteoarthritis primarily affects joint cartilage, causing pain and stiffness, while osteoporosis weakens bones, leading to fractures and postural changes.
However, because osteoporosis increases the risk of fracture, it is considered riskier than osteoarthritis. The complications that can occur after an osteoporotic fracture are shock, disrupted blood supply, internal bleeding or swelling of tissue, blood clots, blocked blood vessels, infection, death of bone tissues, reaction to internal fixation devices, regional pain, formation of extra-skeletal bones, etc.
For Osteoarthritis, a website suggests this condition ‘does not cause bone loss or fractures. On the contrary, it is associated with increased bone density and abnormal growths (osteophytes) due to the deficiency in bone resorption’. This evidence clearly indicates that these condition spread through different mechanisms in the body.
Osteoarthritis is a joint disease, while osteoporosis is a bone disorder. Although they can coexist, their symptoms and impact vary. A 2013 study found an inverse relationship between them, meaning a higher risk of one decreases the chance of the other, but this may not apply universally.
