Left Knee Pain Overview

No doubt, left knee pain is very discomforting and unpleasant and it has come up as one of the conditions with the highest medical complaints. An upside about this condition is that it can be treated very easily.

With the above information, it has become evident that knowing the cause of the pain and proper diagnosis is important in treating left knee pain.

Causes of left knee pain

The knee is a complex joint that comprises three different bones. The first is the lower thighbone, the second is the upper shinbone, and the third is the kneecap. All of these bones are held together by very strong tendons and ligaments. Cartilage is also present beneath the kneecap and it functions as a cushion for the bones and also to help in stabilizing the knee.

When any of these structures is affected by injury, infection, or other forms of the disease, you begin to experience pain. The degree of the pain and how long it will last depends on the cause.

The common causes of left knee pain are:

Knee arthritis.

There are several types of arthritis that may affect the knee. The most common types are:

  1. This form of arthritis is a result of wear and tear on the cartilage beneath the kneecap. People above the age of 50 are more prone to this condition. The pain increases with the deterioration of the cartilage and it could escalate really fast depending on the speed of deterioration.
  2. Rheumatoid arthritis. This is a result of autoimmune activity where the joints in the body are attacked by the person’s immune system. Some major symptoms are redness of the area, swelling, warmth of the area, and pain. The pain reduces with more activity.

Ligament injuries

Your knee has four ligaments. Two of these are cruciate ligaments while the other two are collateral ligaments.

  1. Cruciate ligament injuries. The two ligaments, posterior and anterior, cross each other in the joint with the latter in front and the latter behind. The anterior cruciate ligament is more prone to injury, usually from sudden twists while running and direct blows. The posterior injuries are rare and are caused as a result of strong blows to the knee.
  2. Collateral ligament injuries. The two ligaments, medial and lateral, are located on the sides of the knees. The ligaments connect the lower leg bone to the thighbone. The medial collateral ligament is usually affected by an external blow that ends up causing internal knee pain. The direct opposite is the case for the lateral collateral ligament.

Torn Knee Cartilage

This is very common among young people, especially athletes. Older people experience it because the cartilage in the knee gets weaker with age. When this occurs you hear a popping sound which is followed by swelling and stiffness. The knee will also click, lock, or catch.

Patellar Tear and Tendonitis

Patellar tendonitis is a condition where the patellar tendon is inflamed. It is also most common among sportspeople as well as those who have to run or jump a lot on their jobs. The pain is usually dull and becomes sharp when there is activity.


This is likely to result from blows to the knee which could be from car accidents, falls, or some other source of trauma. Symptoms stiffness, swelling, buckling, or shifting to one side.


This is a result of an accumulation of uric acid in the left knee joint. Crystals are formed by the uric acid in the joint. It usually causes severe and burning pain as well as redness, swelling, and warmth in the area.

Other causes include:

  1. Knee joint infection
  2. Fracture
  3. Tumors
  4. Plica syndrome
  5. Prepatellar bursitis

How do You Know When to See the Doctor?

When you notice any of these signs then you know you have to visit the doctor:

  1. Injury leading to deformity in the joint.
  2. Inability to bend the knee
  3. Swelling
  4. Uncomfortable movement
  5. When you feel a sharp pain in the knee at night or when you are resting
  6. Any other symptom that seems unusual.

  2. Physical therapy.
  3. Medications such as NSAIDs, injections, painkillers, etc.
  4. Surgery is the last option if all the other methods have failed.
