Osteoarthritis is the most common type of arthritis that affects the knee. Osteoarthritis is a degenerative process where the cartilage in the joint gradually wears away. It often affects middle-age and older people. Osteoarthritis may be caused by excess stress on the joint such as repeated injury or being overweight.
Make an appointment with your doctor if your knee pain was caused by a particularly forceful impact or if it's accompanied by: Significant swelling. Redness. Tenderness and warmth around the joint.
If your affected knee appears misshapen compared to your healthy knee, you may have a fracture, dislocated knee cap, or patella injury. When your knee pain progresses enough to give you a limp or make you avoid walking, see a doctor. Pain of this intensity can indicate a bone injury or a degenerative condition.
There are many signs and symptoms of arthritis of the knee: Creaking, clicking, grinding or snapping noises (crepitus). Difficulty walking. Joint pain that changes (gets better or worse) depending on the weather.
Common examples include tendinitis or a tendinopathy (where the tendon – often the patellar tendon – becomes inflamed as a result of overuse) and bursitis (where one or several fluid-filled pockets in your knee joint swell up and restrict movement).
The joint may become stiff and swollen, making it difficult to bend and straighten the knee. Pain and swelling may be worse in the morning, or after sitting or resting. Vigorous activity may cause pain to flare up.
Often when the cause of bad knee pain is left untreated it can lead to further injury and serious complications. Your knee may swell, become unstable, lock up, and/or develop a deformity. Unbearable knee pain will not go away until you finally seek treatment.

Knee bursitis is inflammation or irritation of one or more of the bursae in your knee. Knee bursitis is inflammation of a small fluid-filled sac (bursa) situated near your knee joint. Bursae reduce friction and cushion pressure points between your bones and the tendons, muscles and skin near your joints.
People with knee osteoarthritis may reduce their risk of knee pain by walking more, according to a study published online June 8, 2022, by Arthritis & Rheumatology. Researchers looked at the walking habits of more than 1,200 people with knee osteoarthritis (average age 63, 45% men).
Rheumatoid arthritis is an autoimmune disease. Normally, your immune system helps protect your body from infection and disease. In rheumatoid arthritis, your immune system attacks healthy tissue in your joints.
Rheumatoid arthritis, or RA, is an autoimmune and inflammatory disease, which means that your immune system attacks healthy cells in your body by mistake, causing inflammation (painful swelling) in the affected parts of the body. RA mainly attacks the joints, usually many joints at once.
The most common viruses causing arthritis and/or arthralgias are parvovirus, the alphaviruses, hepatitis B, hepatitis C, Epstein-Barr virus (EBV), and tropical viruses, such as Zika and chikungunya (CHIKV).
Knee pain may be the result of an injury, such as a ruptured ligament or torn cartilage. Medical conditions — including arthritis, gout and infections — also can cause knee pain. Many types of minor knee pain respond well to self-care measures. Physical therapy and knee braces also can help relieve pain.
You'll only need 1 or 2 days of rest to ease minor knee pain, but severe injuries may keep you off your feet longer. Talk to your doctor if it doesn't get better after a few days.
Fibromyalgia often is mistaken for RA, osteoarthritis (OA), Lyme disease, chronic fatigue syndrome, underactive thyroid, depression, and lupus.
X-rays provide clear, detailed images of the knee joint and may reveal bone spurs or narrowing of the joint, the classic hallmark for diagnosing osteoarthritis of the knee. A healthy knee joint appears to have a gap between the bones on an X-ray because the cartilage acts as a cushion between the femur and the tibia.
Here is a look at the stages of osteoarthritis of the knee ranging from normal, minor, mild, moderate and severe stages, with appropriate treatment plans.
Both vitamin D deficiency and quadriceps muscle weakness are associated with knee osteoarthritis (KOA) and pain.
Sudden knee pain
All may be caused by a tear in the cartilage of the knee joint known as the meniscus. Any activity that causes twisting or rotating of the knee can lead to a torn meniscus. Rest, ice and pain relievers may help with pain and give the meniscus time to heal.
