Although, knees are considered to be a fairly small part of the body, but a lot can go wrong with them that can drastically affect your everyday life! So, what is the reason for knee pain? Let’s find out.

Understanding knee pain:

Knee pain is among the most common musculoskeletal ailments that can affect people of any age. Depending upon the damage done to the cartilage in the joint, the pain can go from mild to moderate and from moderate to chronic. The most affected are the ones who suffer from severe pain in the joints as it limits their day-to-day activities and prove to be a hindrance in leading an active lifestyle.

Poor dietary choices, injury, degenerating bone health and underlying infection are some of the reasons that can lead to wear and tear of the cartilage and pain in the affected area. While mild kind of knee pain may respond well to self-care measures, chronic or severe kinds may require medical intervention followed by intensive physiotherapy or even surgery, in some cases. To avoid reaching the stage of chronic or severe knee pain, one must not ignore the very first sign of discomfort in the knees and take adequate steps immediately.

Knee pain reasons:

What is the reason for knee pain? Isn’t it the most commonly asked question by those who could have been experiencing it for a prolonged period of time? Yes, it is. But do they often get the correct answer? We doubt! Therefore, we have listed here some of the most common knee pain reasons that would help you not only understand your condition better but also take the necessary steps to treat it in-time, reduce symptoms and regain mobility.

1) Trauma:

Since knee is considered to be the most injury-prone joint, listing trauma as the one of the possible reasons of knee pain would not be wrong. It is so because the overall structure and components of the knee makes it vulnerable to certain kind of injuries that can cause pain and prevent its functioning. The knee is made up of three major ligaments called:

– The anterior cruciate ligament (ACL)

– The medial collateral ligament (MCL)

– The posterior cruciate ligament (PCL)


Impact of any kind like twisting, overworking of the joints, sudden jerk, rupture, or direct impact to the area can cause damage and aggravate pain, swelling and inflammation in the knees. Athletes are most susceptible to this kind of pain as they constantly engage in activities like running, jumping, and lifting heavy weights which often result in torn ligament or tendon damage.

Less severe impact can be treated with adequate rest and physiotherapy but in case of severely ruptured tendon, surgery may be advised.


2) Degenerative tissue disorders:

Thinking what is the reason for knee pain? It could be the result of degeneration in cartilage and surrounding tissues of the knee! The problem of degeneration of tissues arises due to osteoarthritis and can further give rise to the issues of severe pain, stiffness and joint dysfunction. It is occurs most commonly as a result of aging and most people over the age of 60 are found to be experiencing it. Although there is no specific cure for this problem, regular physical therapy and few lifestyle changes can help manage pain and prevent the damage from spreading further.


3) Dislocated kneecap:

Kneecap sits over the front of the knee and it glides over a groove in the joint when you bend or straighten your leg. When the kneecap dislocates, it comes out of the groove resulting in the supporting tissue to be torn. Injury, sudden blow or change in the direction of the leg are thought to be the most widely known knee pain reasons in case of dislocated kneecap. In such cases, surgery is advised by the doctor in order to repair the damaged and dislocated structures in the knee. It may take about 6-7 weeks to heal from dislocated kneecap.


4) Gout:

The symptoms of gout can appear suddenly and without warning and can lead to redness, swelling, extreme pain and warmth in the knee area. The symptoms of gout are a result from build-up of uric acid crystals in the joint. These needle-like, microscopic crystals collect in the soft tissue of the joint, causing pain that can be excruciating pain.


5) Osteonecrosis of the knee: Among the possible reasons of knee pain is osteonecrosis of the knee. It is a condition in which bone tissue dies due to a lack of adequate blood supply. Its symptoms include joint swelling, pain while bending or straightening the knee or tenderness in the insides of the knee. As a result, the person suffering from it may limp while walking.


6) Knee arthritis:

It could be of two kinds:

  • Knee osteoarthritis: It is among the most common knee pain reasons and gets worse with age.
  • Rheumatoid arthritis: It is a type of auto-immune disorder that usually affects the joints in the hands and wrists before spreading to other parts of the body. It causes redness, swelling and extreme inflammation in the joints.
