Excess soft tissue on the inner side of the knee joint

Excess soft tissue on the inner side of the knee joint is usually caused by excessive obesity, genu valgum (knock-knee), or pes anserine bursitis. Specific analyses are as follows:

1. Excessive Obesity

When excess fat accumulates in the body, subcutaneous fat thickens throughout the body. The soft tissues on the inner side of the knee joint are naturally thicker than those on the outer side, leading to the appearance of excess "meat" or bulkiness. This condition typically improves naturally with weight loss and generally does not require specific treatment.

2. Genu Valgum (Knock-Knee)

This is a type of lower limb deformity. Early symptoms typically include abnormal leg appearance and gait. Because the medial tibia tends to protrude, it may result in a visibly bulging inner knee area that appears as excess soft tissue. In early stages, corrective exercises may help correct the alignment. If conservative correction is ineffective, surgical intervention such as valgus knee replacement may be required.

3. Pes Anserine Bursitis

This is a form of aseptic inflammation affecting soft tissues. When the bursa on the inner side of the knee joint becomes irritated, it may lead to bursal swelling or hyperplasia, causing pathological thickening or enlargement on the inner side, often accompanied by pain. For severe inflammation, medications such as diclofenac sodium tablets or ibuprofen tablets may be used under medical supervision to alleviate symptoms.

In addition, this condition may also be associated with other disorders such as medial collateral ligamentitis or medial synovitis of the knee joint. Patients experiencing these symptoms along with additional discomfort should seek timely medical evaluation and appropriate treatment.
