Understanding Knee Pain: Causes and Symptoms

Knee pain is a common ailment that can affect people of all ages, limiting mobility and impacting daily activities. The knee is a complex joint that plays a crucial role in supporting the body's weight and facilitating movement. Various factors can contribute to knee pain, and understanding the causes and symptoms is essential for proper diagnosis and effective management.

Causes of Knee Pain:


Ligament injuries: Tears or sprains in ligaments such as the ACL (Anterior Cruciate Ligament) or MCL (Medial Collateral Ligament) can result from sports injuries or sudden twisting motions.

Meniscus tears: The meniscus, a rubbery disc that cushions the knee joint, can tear due to forceful rotations or sudden stops.

Tendon injuries: Overuse or repetitive stress can lead to conditions like tendinitis, where the tendons around the knee become inflamed.


Osteoarthritis: Wear and tear of the joint over time can lead to osteoarthritis, causing pain, stiffness, and reduced flexibility.

Rheumatoid arthritis: An autoimmune condition that can affect the knee joint, leading to inflammation and pain.

Medical Conditions:

Gout: Accumulation of uric acid crystals in the knee joint can cause sudden and severe pain.

Bursitis: Inflammation of the bursae, small sacs that cushion the knee joint, can result in pain and swelling.

Overuse and Strain:

Repetitive activities, such as running or jumping, can lead to overuse injuries and strain on the knee joint.

Age-Related Changes:

As people age, the cartilage in the knee may wear down, leading to pain and discomfort.

Symptoms of Knee Pain:


Sharp, stabbing pain or a dull, aching sensation in or around the knee joint.


Inflammation and swelling may occur, making the knee appear larger than usual.


Difficulty bending or straightening the knee, especially after periods of inactivity.


Feeling of instability or weakness in the knee, making it challenging to support the body's weight.

Clicking or Popping:

Audible sounds or sensations when moving the knee, which may indicate issues like meniscus tears.

Redness and Warmth:

Inflammatory conditions may cause the knee to feel warm to the touch and appear red.

Acupuncture can effectively help to reduce knee pain.
