Knee ostoearthritis is a degenerative joint disease that can cause pain, stiffness, and reduced mobility in the knee joint. This condition occurs when the protective cartilage that cushions the bones in the knee joint wears down over time, leading to bone-on-bone contact and joint damage.

Symptoms Of Knee Ostoearthritis

The symptoms of knee ostoearthritis (ข้อเข่าเสื่อม, which is the term in Thai) can vary from person to person, but they often include:

  • Pain or tenderness in the knee joint, especially when walking or bending the knee
  • Stiffness in the knee joint, especially after sitting or lying down for an extended period
  • Swelling or inflammation around the knee joint
  • A crunching or grinding sensation in the knee joint when moving it
  • Reduced range of motion in the knee joint, making it difficult to straighten or bend the knee fully

Causes Of Knee Ostoearthritis

Knee ostoearthritis can be caused by several factors, including:

  • Age: As we age, the cartilage in our knee joint can break down and wear away, leading to osteoarthritis
  • Genetics: Some people may be more susceptible to developing knee ostoearthritis due to genetic factors.
  • Injury: A knee injury, such as a torn ligament or meniscus, can increase the risk of developing knee ostoearthritis later in life.
  • Overuse: Repeated stress on the knee joint, such as from certain types of exercise or physical labor, can cause the cartilage to wear down faster than normal.

Diagnosis Of Knee Ostoearthritis

To diagnose knee ostoearthritis, a doctor will typically perform a physical exam and may order imaging tests such as X-rays or MRI scans. During the physical exam, the doctor will look for signs of joint damage, such as swelling or reduced range of motion. Imaging tests can help the doctor see the extent of the joint damage and determine the best treatment options.

Treatment Options For Knee Ostoearthritis

There are several treatment options for knee ostoearthritis, including:

Losing weight, exercising regularly, and avoiding activities that stress the knee joint can help reduce symptoms and slow the progression of knee ostoearthritis. Medications: Over-the-counter pain relievers, such as acetaminophen or ibuprofen, can help manage pain and inflammation. Prescription medications like corticosteroids or hyaluronic acid injections may also reduce pain and improve joint function.

Working with a physical therapist can help improve joint mobility, reduce pain, and strengthen the muscles around the knee joint. Wearing a knee brace or sleeve can provide support and compression to the knee joint, reducing pain and improving stability.

In severe cases of knee ostoearthritis, surgery may be necessary to replace the damaged joint with an artificial joint. This procedure, known as a knee replacement, can significantly improve joint function and reduce pain.


Knee ostoearthritis is a common condition that can cause significant pain and discomfort for those who suffer from it. Fortunately, several treatment options are available, ranging from lifestyle changes and medications to physical therapy and surgery.
