Knee Bump Below Kneecap: Causes, Symptoms, and Treatment Options

Common Causes

Osgood-Schlatter Disease

A frequent cause in adolescents, this condition involves inflammation of the patellar tendon attachment to the tibia. It produces pain, swelling, tenderness, and a palpable bump below the kneecap.

Chondromalacia Patellae (Runner's Knee)

Degeneration of the cartilage under the kneecap leads to similar symptoms—pain, swelling, tenderness—and can also cause a bump to form.

Bone Tumor

Though rare, benign or malignant bone tumors in the knee region can present as a bump with pain, swelling, and tenderness.

Diagnosis and Medical Evaluation

Any persistent bump below the kneecap warrants a medical examination to determine the exact cause and appropriate treatment plan.

Home Relief Measures

• Rest: Avoid high-impact activities like running or jumping.
• Ice: Apply ice packs for 15–20 minutes several times daily.
• Elevation: Prop the knee up on a pillow when sitting or lying down.
• Over-the-counter analgesics: Ibuprofen or acetaminophen can reduce pain and inflammation.

If symptoms do not improve or worsen, seek prompt medical attention.
