What are the treatments for the condition?

For common knee pain, such as that from injury or osteoarthritis, over-the-counter pain medications are often used. If an infection is present, antibiotics may be needed. If a serious injury occurs, surgery may be needed. Long-term arthritis may destroy a joint and require a total knee replacement.

Autoimmune disorders are often treated with medications to suppress the immune system and reduce inflammation. If a tumor or cancer is the cause of pain, surgery, chemotherapy, or radiation therapy may be needed.

What are the side effects of the treatments?

Side effects depend on the treatments used. For instance, aspirin and antibiotics can cause stomach upset and allergic reactions. Any surgery carries a risk of bleeding, infection, or allergic reactions to anesthesia.

What happens after treatment for the condition?

Pain medication can be increased, changed, or decreased as needed. Someone with an injury often heals with treatment and needs no further monitoring. A person with a tumor or cancer may need regular monitoring for years after treatment.

How is the condition monitored?

Those with autoimmune disorders may need repeat blood tests to help monitor their disease. Any new or worsening symptoms should be reported to the healthcare provider.
