Knee Pain - A Condition with Multiple Causes

The knee joint is one of the most important as it helps perform various leg movements like bending, walking, running, climbing, and numerous other sports activities. When the knee joint becomes painful, the leg movements become limited and the affected person walks with difficulties.

There could be multiple reasons for knee pain and most of them can be fixed with medication, rest, and physical therapy. Only severe cases will require surgery and depending upon the condition, orthopedic implants may also be used.

Siora Surgicals is a reliable manufacturer and Supplier for Orthopedic Implants that are required during different orthopedic surgeries.

In this post, we are going to discuss some of the common conditions that may result in knee pain.

Causes of Knee Pain

Ligament Sprains

A ligament is a tough band of connective tissues that hold the knee joint together. When an injury occurs to ligaments present in the knee joint, it will cause pain. This condition occurs due to sudden twisting of the knee joint or when excessive force is applied. If ligament tear occurs, swelling is also noticed along with pain. Anterior cruciate ligament tear is one of the commonly occurred causes of knee pain.

Tendon Tears

Tendon tears most commonly occur due to overstretching and in most cases, bleeding could also occur in the tendons. In maximum cases, tendon tears heal on their own with no requirement for surgery. Athletes are more prone to getting tendon tears due to their engagement in high-impact activities plus, trauma is another cause of this condition.

Cartilage Tears

Cartilage tears in the knee joint are common and one of the most commonly seen conditions is torn or split meniscus. The causes of this condition could be a severe impact on the knee or sudden twisting, especially while performing weight-bearing exercises. Besides this, elderly people are also prone to getting cartilage tears due to natural wear & tear in them. This condition can be fixed with medication and physical therapy but, in certain cases, damaged cartilages need to be trimmed or removed by performing a surgical procedure.

Patello-Femoral Pain Syndrome

This is the condition in which pain is experienced at the back of the kneecap. The patello-femoral syndrome is characterized by damage to the cartilage present under the kneecap. This damage could result due to an injury or overuse. Sportspeople are more prone to developing this condition due to the type of activities they engage in. The pain caused by patello-femoral syndrome increases with movements like squatting and stair climbing. Proper rest, prescribed pain-relieving medication, and physiotherapy sessions are known to relieve pain caused by this condition.

Common Symptoms of Knee Pain

The cause of the knee pain decides the severity & location and symptoms will be based on these factors too. Below-mentioned are some of the commonly noticed symptoms in people with knee pain:

  • Stiffness and swelling

  • Redness

  • Warm to touch

  • Joint instability or weakness

  • Popping or crunching noise during knee movement

  • Difficulty in completely straightening the knee joint


The treatment of knee pain will solely depend upon the cause and its severity. In most cases, medications and rest relieve the symptoms whereas certain severe conditions might require surgery.
