The area where the inner side of the right knee bone protrudes hurts when pressed.

Generally, pain upon pressing the inner side of the right knee where the bone protrudes may be caused by factors such as osteoarthritis of the knee joint, patellar chondromalacia, or ligament injury. Specific analyses are as follows:

1. Osteoarthritis of the Knee Joint

This is a degenerative bone joint disease caused by arthritis, which leads to pain and stiffness. It may result in cartilage damage and degeneration, changes in bone structure, and joint instability. This condition is often accompanied by symptoms such as local bone spurs (osteophytes) and bone density loss. In such cases, patients can take medications like aspirin capsules or meloxicam tablets under medical guidance to relieve symptoms.

2. Patellar Chondromalacia

Also known as softening of the knee cartilage or patellofemoral pain syndrome, this condition involves degeneration and wear of the patellar cartilage. Depending on the severity, patients may experience localized pain and discomfort. Under medical advice, patients can use medications such as glucosamine capsules or ibuprofen tablets for treatment.

3. Ligament Injury

Sudden twisting or impact during landing can cause injury to the medial ligaments of the knee, commonly resulting in pain. Patients may follow medical advice to use non-steroidal anti-inflammatory drugs (NSAIDs) to alleviate symptoms, such as diclofenac sodium sustained-release tablets or sustained-release ibuprofen capsules.

In addition, similar pain could also be caused by conditions such as bursitis or leg fractures. It is important to note that if such pain occurs, timely medical consultation is necessary. Appropriate treatment should be initiated after proper examination and diagnosis by a physician.
