Knee OA / Knee Arthritis

Knee OA can involve multiple pathophysiological changes such as cartilage degradation, bony adaptations, meniscal damage, and synovial inflammation.

There are three main contributors to the pain experienced by people with osteoarthritis of the knee.
1. The first is the periosteum. The periosteum is a thin tissue that wraps around the bone. It supplies blood to the bone, and it does have nerve endings. Anyone who has broken a bone knows this very well. It is the tearing of the periosteum that leads to a lot of the pain.The first is the periosteum.

2. The second issue that can cause knee pain and swelling is the synovium. The synovium is the lining of the knee joint. It’s like a balloon that surrounds the bones of the knee. There are many nerve endings there. Synovitis can be a very painful process. As an aside, for people with pain due to synovitis that does not respond to time, ice, heat, medications. red and angry periosteum.

3. The third contributor to pain in an arthritic knee is edema or inflammation in the bone itself. This occurs more often in women because of some degree of osteopenia or osteoporosis. That makes the bone a little weaker. So when the cartilage thins, the cushioning is also thinning. Less cushioning may cause increased stress in the bone, which can cause edema. Bone marrow edema can cause a deep, intense ache.
