Knee Arthritis
The most common cause of Knee Arthritis is Knee Osteoarthritis (OA).
Knee osteoarthritis is a degenerative knee condition where the articular cartilage of your knee joint gradually wears away, exposing the underlying bone.
As your knee arthritis progresses, bony spurs also develop in and around your knee joint in response to the change in load distribution and biomechanics.
Within your knee there are two joints which can be affected by knee arthritis: the tibiofemoral joint - the joint between your thigh bone (femur) and your lower leg (tibia) and the patellofemoral joint (the joint between the kneecap and the femur itself).
