Introduction
Pain in the tendons below the knee may be caused by conditions such as osteoarthritis, patellar tendonitis, or knee ligament injuries. This pain could result from knee osteoarthritis, primarily due to chronic injury, obesity, or nutritional changes. Additionally, pain below the knee may also be triggered by exposure to cold or meniscus damage. Patients should promptly visit a hospital for imaging examinations and related diagnosis and treatment.

Pain in the tendon below the knee may be caused by conditions such as knee arthritis, patellar tendinitis, or knee ligament injury.

1. Knee Arthritis

Pain in the tendon below the knee may result from knee arthritis, primarily due to chronic injuries, obesity, or nutritional changes. These factors can lead to redness, swelling, and pain in the knee joint area. Pain below the knee may also occur and, in severe cases, normal activities may be affected. If the pain is severe, medications such as ibuprofen tablets or celecoxib tablets may be taken under a doctor's guidance.

2. Patellar Tendinitis

Patellar tendinitis may arise from long-term chronic overuse, causing an aseptic inflammation at the tibial attachment site of the patellar tendon, which can also lead to pain in the tendon below the knee. If symptoms are not severe, patients should ensure adequate bed rest. When necessary, nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen tablets or diclofenac sodium tablets, may be taken under medical supervision.

3. Knee Ligament Injury

Knee ligament injuries may be caused by significant external trauma, resulting in severe pain and joint swelling. Some patients may also develop joint effusion, leading to pain below the knee. In cases of severe pain, prompt medical evaluation is essential. Treatment, if needed, may include immobilization with a cast or ligament reconstruction surgery, as directed by a physician.

Besides the above, tendon pain below the knee may also be caused by exposure to cold or meniscus injury. Patients should promptly visit a hospital for imaging tests and related evaluations for accurate diagnosis and treatment.
