OSTEOARTHRITIS OF THE KNEE
Individuals who develop knee OA experience a wide range of symptoms based on the progression of the disease. Pain occurs when the cartilage covering the bones of the knee joint wears down. This narrows the space between the bones and causes friction. Since the knee is a weight-bearing joint, your activity level, and the type and duration of your activities usually have a direct impact on your symptoms. Symptoms of knee OA may include:
- Worsening pain during or following weight bearing activity
- Pain or stiffness after sitting for a prolonged period of time
- A feeling of popping, cracking, or grinding when moving the knee
- Swelling following activity
- Tenderness to touch along the knee joint
Typically these symptoms do not occur suddenly or all at once, but instead they develop gradually over time. Sometimes individuals do not recognize they have osteoarthritis because they cannot remember a specific time or injury that caused their symptoms. If you have had worsening knee pain for several months that is not responding to rest, it is best to seek the advice of a medical provider.
