Introduction
Medial knee pain may be caused by physiological factors, or by conditions such as meniscus injury and osteoarthritis of the knee joint. The medial meniscus can become injured during flexion movements, potentially leading to meniscal tear, which mainly presents as pain and restricted movement. Arthroscopic surgery is required to repair the torn meniscus. In addition to these common causes, tumor-like lesions are also possible.

Medial knee pain may be caused by physiological factors or conditions such as meniscus injury and osteoarthritis of the knee joint. Specific analyses are as follows:

I. Physiological Factors

Increased daily physical activity may lead to tension in the surrounding tendons and ligaments, causing pain. This is a normal physiological phenomenon and does not require special treatment.

II. Pathological Factors

1. Meniscus Injury

The medial meniscus of the knee joint may become injured during flexion movements, potentially resulting in meniscal tear. The main symptoms include pain and restricted movement. Arthroscopic surgery is required to suture the meniscus.

2. Osteoarthritis of the Knee Joint

Frequent weight-bearing on a single femoral condyle may cause medial knee pain and can lead to joint varus deformity. This condition is primarily due to knee osteoarthritis and is more common in elderly individuals. Under medical guidance, intra-articular injection of sodium hyaluronate solution or unicompartmental knee replacement can be performed, which can effectively relieve pain symptoms.

In addition to the above common causes, tumor-like lesions are also possible. Patients should seek timely medical evaluation to determine the exact cause and receive appropriate treatment when necessary.
