About Knee Pain

Knee pain is a common complaint that can affect people of all ages. It can be caused by a wide range of conditions and injuries, leading to discomfort, swelling, and reduced mobility in the knee joint.

Possible Causes of Knee Pain (with descriptions)

Knee pain can result from various factors, including:

  • Arthritis: Osteoarthritis, rheumatoid arthritis, and other types of arthritis can cause knee pain due to inflammation and cartilage damage.
  • Meniscus Tear: A tear in the meniscus, the cartilage that cushions the knee joint, can cause pain, swelling, and locking of the knee.
  • Anterior Cruciate Ligament (ACL) Injury: A tear or sprain in the ACL, often due to sports injuries, can lead to knee instability and pain.
  • Patellar Tendonitis: Inflammation of the patellar tendon, commonly known as jumper's knee, can cause pain in the front of the knee.
  • Bursitis: Inflammation of the bursae, small fluid-filled sacs that cushion the knee joint, can result in knee pain and swelling.
  • Overuse or Repetitive Strain: Activities that involve repetitive bending, squatting, or kneeling can lead to knee pain from overuse injuries.

Symptoms Linked to Knee Pain

Common symptoms associated with knee pain include:

  • Pain, discomfort, or aching in the knee joint
  • Swelling, redness, or warmth around the knee
  • Stiffness or difficulty moving the knee
  • Popping, clicking, or grinding sensations in the knee
  • Weakness or instability in the knee

Diagnosing Knee Pain

Diagnosing the cause of knee pain may involve:

  • Medical History Review to assess symptoms, previous injuries, and medical conditions
  • Physical Examination to evaluate knee function, range of motion, and signs of injury or inflammation
  • Imaging Studies such as X-rays, MRI, or CT scans to visualize knee structures and detect abnormalities
  • Joint Aspiration to analyze the joint fluid for signs of infection or inflammation

Treating Knee Pain

Treatment for knee pain depends on the underlying cause and may include:

  • Rest and Activity Modification to avoid aggravating the knee
  • Ice and Heat Therapy to reduce pain and swelling
  • Medications such as nonsteroidal anti-inflammatory drugs (NSAIDs), acetaminophen, or corticosteroids
  • Physical Therapy and Exercise Programs to strengthen muscles, improve flexibility, and support knee stability
  • Bracing or Orthotics to provide support and alignment for the knee
  • Injections such as corticosteroids, hyaluronic acid, or platelet-rich plasma (PRP) for pain relief and inflammation reduction
  • Surgery for severe cases or when conservative treatments fail, including arthroscopic surgery, knee replacement, or ligament reconstruction

Possible Treatments

Treatments for knee pain offered by interventional pain management physicians, rheumatologists, and orthopedic surgeons may include:
