ALL ABOUT OSTEOARTHRITIS

​What is Osteoarthritis (OA)?
Osteoarthritis (骨关节炎 Gǔ guānjié yán) is the most common form of arthritis.  It is often referred to as a degenerative joint disease, a chronic joint condition characterized by the gradual deterioration of the cartilage that cushions the ends of bones in a joint. This is a long-term condition that leads to pain, stiffness, swelling, and decreased joint mobility. While OA can affect any joint in the body, it most commonly impacts the knees, hips, hands, and spine. Though OA occurs usually with age but it is accelerated by overuse, injury or obesity.  As OA progresses, pain can become constant and severe, even at rest.

Symptoms of Osteoarthritis
  • Joint Pain: The hallmark symptom of OA is joint pain, typically occurring after physical activity or prolonged use of the affected joint.
  • Stiffness: Morning stiffness and decreased joint flexibility are early indicators of OA.
  • Tenderness: The affected joint may be tender to the touch.
  • Mild Swelling: Some individuals may experience minor swelling around the joint.
  • Joint Deformity: Joints may become visibly deformed and lose their normal shape.
  • Limited Mobility: OA can significantly limit joint mobility, making daily activities challenging.
  • Bone Spurs: The development of bone spurs (osteophytes) in and around the joint can occur, causing further discomfort.

Diagnosis of Osteoarthritis
Diagnosing OA involves a combination of medical history, physical examination, and imaging tests. Doctors will typically:
  • Review Medical History: Your doctor will ask about your symptoms, their duration, and any factors that worsen or alleviate them.
  • Physical Examination: A physical examination of the affected joint(s) will be conducted, assessing for tenderness, swelling, and range of motion.
  • Imaging Tests: X-rays, MRI scans, or CT scans may be ordered to visualize the joint's condition, including cartilage loss and bone changes.
  • Blood Tests: While not definitive for OA, blood tests can help rule out other forms of arthritis.

4 Stages of Osteoarthritis
To better understand osteoarthritis, it's essential to recognize the various stages it progresses through. 

Stage 1: Early Osteoarthritis (Joint Wear and Tear) - Minor
At this stage, the joint cartilage starts to deteriorate, but the changes are usually minimal and may not even be noticeable to the individual as there is little or no pain at the affected area.

Stage 2: Mild Osteoarthritis (Cartilage Loss and Joint Changes)
As osteoarthritis progresses, the joint deterioration becomes more pronounced. The affected area feels stiff and lasts longer after  periods of inactivity.  X-rays may reveal joint space narrowing, bone spurs (osteophytes), and other structural changes. The joint's movement is noticeably reduced and muscles around the affected joint may weaken. Some may need supportive brace for the affected area.

Stage 3: Moderate Osteoarthritis (Advanced Joint Damage) 
In the advanced stage of osteoarthritis, the joint damage is significant, leading to more severe symptoms.  Cartilage begins to erode and inflammation of the joints causes discomfort during normal activities.  Visible joint deformities may occur and ligaments weaken.

Stage 4: End-Stage Osteoarthritis (Total Joint Degeneration) - Severe
At this final stage of osteoarthritis the cartilage is almost completely gone,  joint space may be obliterated, and bone-on-bone contact occurs, leading to an inflammatory response from the joint.  Bony Spurs overgrowth may add on to the severe pain.

How to Manage Osteoarthritis
While there is no cure for OA, effective management strategies can significantly improve the quality of life for individuals with this condition.   Some key approaches include:

Lifestyle Modifications: 
  • Maintaining a healthy weight or weight loss for people with osteoarthritis of weight-bearing joints
  • Engaging in regular low-impact exercise includes muscle strengthening around the affected joint(s)
  • Engaging in regular physical activities in maintaining the range of motion of affected joint(s)
  • Using joint protection techniques can alleviate symptoms.  includes muscle strengthening around the affected joint(s), maintaining the range of motion of affected joint(s).

Physical Therapy: Physiotherapists teach how to properly use joints; exercise correctly in both motion and flexibility.  A personalized exercise plan will be created to improve joint strength and flexibility. For example, the therapist would include hamstring stretch, calf stretch, straight leg raise, side leg raise, heel raise and so on for knee osteoarthritis. Other low impact activities to joints such as brisk walking, cycling, swimming, water aerobics, light gardening, group exercise classes, and dancing may also be included.

Western Medication: Over-the-counter pain relievers, topical creams, and prescription medications can help manage pain and inflammation.

Chinese Medication: Traditional Chinese medication (TCM; 中醫 zhōng yī) and treatment proves highly effective in managing osteoarthritis without having side effects. 

Assistive Devices: Devices such as braces, splints, canes, crutches, walkers, orthopedic shoes and shoe inserts can provide support and reduce strain on affected joints.  It is important to get one that is suitable as a simple device may do more harm if it does not fit you.

Treatment of Osteoarthritis
Western Treatment - In addition to pain relievers and anti-inflammatory drugs, your doctor may prescribe disease-modifying medications like hyaluronic acid or corticosteroid injections. For acute pain, your doctor may recommend steroid injection.  The pain relief injections are usually only temporary and there will be limitations to the number of steroid injections one can receive.  In severe cases, surgical options such as joint resurfacing, realignment, or joint replacement surgery may be considered.

TCM Treatment - TCM physicians usually use a combination of treatment methods such as acupuncture, cupping, tuina and herbal medication.  The ultimate goal in TCM treatment is for the body to heal naturally by allowing the energy flow in the body, also called the ‘Qi’ (气).  For this to happen the ‘Yin’ (阴 yīn) and ‘Yang’ (阳 yáng) in the body need to be balanced.  If yin and yang is imbalanced, it causes blockages in the body and Qi cannot flow freely, thereby causing illnesses and diseases. 
​
Lifestyle Adjustments - Patients are encouraged to exercise regularly (a combination of exercises to strengthen muscles and to improve general fitness) and to make dietary changes, including adding anti-inflammatory foods and maintaining a well-balanced diet.  For example of foods to be included are; 
  • Oily Fish (salmon, tuna, sardines)
  • Dairy Products (milk, yogurt, cheese)
  • Dark leafy greens (spinach, kale, chard, collard greens)
  • Broccoli
  • Green Tea
  • Garlic
  • Nuts

Osteoarthritis is a chronic condition that affects millions worldwide, but with proper management and lifestyle adjustments, individuals can lead fulfilling lives despite its challenges. It's crucial to note that the progression of osteoarthritis can vary from person to person. Early diagnosis and appropriate management, including lifestyle changes, physical therapy, and medications, can help slow the progression and improve the quality of life for individuals with osteoarthritis.

In conclusion, understanding the stages of osteoarthritis is vital for both patients and healthcare providers. Early intervention and management can significantly impact the progression of the disease and improve the overall well-being of those affected by osteoarthritis. If you suspect you have osteoarthritis or are experiencing joint pain, consult a healthcare professional for proper evaluation and guidance.
