How is osteoarthritis diagnosed?

Osteoarthritis (OA) is diagnosed primarily on X-Ray. Magnetic resonance imaging (MRI) may be done later to check for the extent of bone erosion and other injuries to the joint structure. For diagnosing OA, doctors ask for your medical history and look for the signs and symptoms. This is generally done by rheumatologists and orthopedic surgeons.
How is osteoarthritis different from rheumatoid arthritis?
Rheumatoid arthritis (RA) can affect all the joints of your limbs—hands, fingers, elbows, knees, and hips. Meanwhile, osteoarthritis (OA) frequently affects your knees, hip, and spine.
RA always affects multiple joints on both sides of the body, whereas OA may only affect one particular joint or area of the body.
Most often, RA is frequently accompanied by signs such as joint swelling, tenderness, and fever. RA may also involve the lungs, eyes, and other organs. These signs are usually not seen in OA.
What is the best treatment for osteoarthritis?
Once osteoarthritis (OA) starts developing, you can only slow down the progression of the disease and not reverse it. The best treatment for OA varies from person to person. Most often, a combination of various therapies gives the best results. These therapies include the following:
Physical measures
- Excess weight puts pressure on your knee joints, hips, and lower back. Weight loss can reduce your chances of disability due to OA.
- Exercise can improve your muscle strength and reduce joint pain and stiffness.
- Supportive devices, such as a walking cane, can help you walk with ease.
- Heating pads/bags or cold therapy can help relieve OA symptoms temporarily.
- Alternative/complementary therapies such as hot fomentation (spa), massage, acupressure, and acupuncture can help relieve pain for a short time.
Drug therapy
- Nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin, ibuprofen, naproxen, and acetaminophen can help relieve the pain and swelling in patients with OA. These can be in the form of topical gels, oral pills, or injections.
- Some medications work to change how your body responds to pain. Popular options include prescription opioids containing oxycodone or hydrocodone. Opioids can be addictive.
- Cymbalta (Duloxetine) is also one of the effective drugs for pain associated with chronic OA.
- Narcotics such as oxycodone and hydrocodone are prescribed if you have extreme joint pain or fail to respond to NSAIDs and analgesics.
- Sometimes, a steroid drug or lubricant, such as hyaluronic acid, is injected into the painful joints. These shots may help delay the need for knee replacement surgery by a few years in some patients with OA.
Surgery
- Surgical treatment becomes an option for severe cases that do not get any relief from the aforementioned treatments. This can be in the form of arthroscopy or knee replacement surgery.
- Arthroscopy helps in repairing the joint damage by inserting a long camera like a tube in your knee.
- Knee replacement surgery is mostly advised in severely damaged knee joints, particularly if you are obese.
Supplements
- Many over-the-counter dietary supplements, such as calcium, vitamin D, omega-3 fatty acids, glucosamine, and chondroitin, are used in the treatment of OA.
- However, first, you need to consult your doctor if you are on some other medicines to avoid drug interactions.
What happens if osteoarthritis is left untreated?
Osteoarthritis (OA) of the knees or hips can lead to the following complications:
- Deformities such as a bow-legged appearance due to knee joint involvement
- Chronic pain due to joint erosion affecting the quality of life
- Pinched nerves causing pain and muscle weakness causing restricted movements
- Stress fractures over weakened bones
- Poor quality of life

Arthritis is defined as painful inflammation and joint stiffness. Osteoarthritis is a type of arthritis and the most common cause of chronic joint pain, affecting over 25 million Americans. Osteoarthritis is a type of arthritis that involves the entire joint. Osteoporosis is not a type of arthritis. It is a disease that mainly is caused by a loss of bone tissue that is not limited to the joint areas. It is possible for one person to have both osteoarthritis and osteoporosis. The differences in the signs and symptoms of osteoarthritis and osteoporosis include; pain, stiffness, and joint swelling, joint deformity, crackle sounds when the joint is moving, and walking with a limp. Osteoporosis is called the "silent disease" because it can progress for years without signs and symptoms before it is diagnosed, severe back pain, bone fractures, height loss, and difficulty or inability to walk. The differences in the causes of osteoarthritis and osteoporosis are that osteoarthritis usually is caused by wear and tear on the joints. Osteoporosis usually is caused by one or more underlying problems, for example, calcium and vitamin D deficiencies. Treatment for osteoarthritis and osteoporosis are not the same. There is no cure for osteoarthritis or osteoporosis.What Are the Four Stages of Osteoarthritis?
The four stages of osteoarthritis (OA) have been graded on the basis of X-ray findings. Higher grades indicate more severe signs of OA and the need for surgery. Grade 0 is the stage when the joint is healthy, Grade 1 is doubtful narrowing of the joint space with possible bone spurs, Grade 2 is the definite bone spurs with possible reduced joint space, Grade 3 is definite moderate joint space narrowing (at least 50%), and Grade 4 is the most severe stage.What Does Boron Do for the Body?
