Arthritis in the knee is a painful condition that gets worse with age. There are two types of arthritis. Rheumatoid arthritis occurs when the immune system, which normally helps protect the body from infection and disease, attacks its own tissues Osteoarthritis, the most common type, can affect one or both knees. The main symptoms include knee pain, swelling, and stiffness. Luckily, there are various treatments available to help manage these symptoms.

What Is Knee Arthritis ?

arthritis in the knee is a condition characterized by pain, swelling, and stiffness in the joints. It commonly affects the largest and strongest joints in the body, particularly the knees. However, there are measures you can take to alleviate symptoms and potentially delay the progression of the disease.

What Is A Knee Joint ?

The knee joint is formed by the meeting of three bones: the thigh bone (femur), the shinbone (tibia), and the kneecap (patella). Cartilage, a smooth substance, covers the ends of each bone, acting as a cushion to prevent them from rubbing against each other. Surrounding the joint is a tissue called the synovial membrane, which lubricates the cartilage to facilitate smooth movement.

Types Of Arthritis 

There are over 100 types of arthritis, but the two most common are osteoarthritis and rheumatoid arthritis.


  • Osteoarthritis, often called "wear and tear" arthritis, is the most prevalent form. It typically develops with age but can also be caused by injury or excess weight. This condition occurs when the cushioning tissue in the joints wears away, leading to pain and stiffness. Osteoarthritis can affect any joint, with hands, knees, hips, and spine being the most common sites.

Symptoms of osteoarthritis vary depending on the affected joints and typically worsen over time. These may include deep joint pain, difficulty with gripping, squatting, or climbing stairs, limited range of motion, stiffness that improves with activity, stiffness after rest, and swollen joints.


  • Rheumatoid arthritis, an autoimmune disease, causes inflammation in the joints. If left untreated, it can result in significant joint damage. This condition usually affects multiple joints and can spread to other parts of the body, such as the heart, lungs, and eyes. Some individuals with rheumatoid arthritis develop lumps over joint areas, commonly on knuckles, elbows, and heels. The exact cause of rheumatoid arthritis is unknown, but it is believed to involve the immune system mistakenly attacks the joints, possibly triggered by a bacterial or viral infection.

Symptoms of rheumatoid arthritis may appear suddenly or gradually worsen over time. They are often more severe than those of osteoarthritis and may include pain, stiffness, or swelling in multiple joints, a symmetrical pattern of inflammation (e.g., both wrists affected), worsening pain and swelling in additional joints over time, persistent swelling affecting daily activities like work, walking, dressing, or driving, and feelings of fatigue and unintended weight loss.


If you notice symptoms of arthritis, it's crucial to consult your doctor promptly. Delaying treatment may lead to more joint damage over time. Your doctor can recommend interventions to slow arthritis progression and maintain your mobility.

Risk Factors for Knee Arthritis 

Risk factors for knee arthritis encompass various aspects that can increase the likelihood of developing this condition:

1. Age: Osteoarthritis, characterized by joint wear and tear, becomes more common as individuals grow older due to the natural degeneration of knee joint cartilage.
2. Heredity: Genetic factors and joint abnormalities passed down through families may contribute to the onset of osteoarthritis in the knee.
3. Excess weight: Being overweight or obese places added strain on the knees, potentially accelerating the deterioration of joint tissues over time.
4. Injury: Severe or repetitive knee injuries, even if they occurred years ago, can raise the risk of osteoarthritis development.
5. Overuse: Occupations or sports involving repetitive knee movements may increase the likelihood of osteoarthritis due to sustained stress on the joint.
6. Gender: Postmenopausal women are more susceptible to osteoarthritis compared to men.
7. Autoimmune triggers: While the exact cause of rheumatoid arthritis remains unclear, certain triggers may prompt autoimmune reactions leading to joint inflammation.
8. Developmental abnormalities: Structural knee deformities like knock-knee or bowleg can place abnormal stress on specific joint areas, accelerating cartilage wear.
9. Other health conditions: Individuals with diabetes, high cholesterol, hemochromatosis (excess iron levels), or vitamin D deficiency may have an elevated risk of developing osteoarthritis.


Diagnosing Knee Arthritis

Diagnosing of arthritis in knee typically involves a series of tests and assessments conducted by your doctor:

1. Medical history and physical examination: Your doctor will review your medical history and conduct a physical examination to assess your knee function, range of motion, and any signs of inflammation or joint abnormalities.

2. Blood tests: Some cases may require blood tests to check for genetic markers or antibodies associated with rheumatoid arthritis.

3. X-rays: X-ray imaging helps identify cartilage loss, bone spurs, and cysts within the knee joint, indicating signs of osteoarthritis. While cartilage itself isn't visible on X-rays, narrowing of the joint space indicates cartilage degeneration.

4. Joint aspiration: This procedure involves extracting synovial fluid from the knee joint for analysis, helping identify inflammation or infection.

Although less common, additional imaging tests such as MRI or CT scans may be necessary in certain cases for a more detailed assessment of the knee joint.


Treatment Options for Arthritis Include:

1. Pain and inflammation-reducing medications: These may include over-the-counter drugs like aspirin, acetaminophen, and ibuprofen, or prescription medications.

2. Immune system-suppressing medications: These drugs can be taken orally or injected into the affected joint to reduce inflammation.

3. Topical creams and ointments: Available over the counter, these treatments are applied directly to the skin to alleviate joint discomfort.

4. Physical therapy: In certain cases, physical therapy sessions can help strengthen muscles and enhance joint flexibility.

5. Surgery: For severely damaged joints, surgical repair or replacement may be necessary. Hip and knee joints are the most commonly replaced.

It's important for individuals with knee arthritis to work closely with their healthcare providers to develop a personalized treatment plan tailored to their specific needs and medical history.

Ask Your Doctor About These Treatment :

Cortisone shots and hyaluronic acid (HA) injections are supported by scientific evidence to alleviate knee arthritis pain. While other injectables like platelet-rich plasma (PRP) and concentrated bone marrow or stem cells show promise, more research is needed to confirm their effectiveness.

These injections offer temporary relief, typically lasting a few months, which can delay the need for surgery and help maintain mobility.


Cartilage Regeneration:
For knees with minimal arthritis and proper bone alignment, newer treatments aim to regenerate cartilage rather than replacing the entire joint.

One such technique is autologous chondrocyte implantation (ACI), where a sample of cartilage cells is grown in a lab and then transplanted back into the knee. This option may be suitable for younger individuals and athletes with cartilage loss.


Radiofrequency Ablation (RFA) for Knee Pain:
If traditional treatments fail to manage knee pain, radiofrequency ablation (RFA) offers another option. RFA involves destroying the sensory nerves responsible for transmitting pain signals from the knee to the brain.

While RFA provides temporary relief, nerves typically regenerate within six months to two years, potentially leading to a return of pain.


Managing knee arthritis involves a mix of treatments and lifestyle changes to ease pain and improve mobility. While complete recovery may not happen, significant relief is possible with medication, therapy, and lifestyle adjustments. Results vary based on arthritis severity and treatment. Consistent commitment to treatment and lifestyle changes is crucial for long-term joint health. With proactive care and support from healthcare providers, individuals can enjoy better quality of life and increased mobility.


Knee arthritis is a common and often painful condition that worsens with age. While there is no cure, various treatments are available to manage symptoms and improve quality of life.
