The knee joint bears significant weight and facilitates movement, making it susceptible to wear and tear. Individuals may experience some degree of discomfort after physical exertion. Discomfort that persists or worsens over time warrants a thorough medical evaluation, and diagnostic imaging helps identify the underlying issues. Here is more information on knee pain, its causes, treatment options, and when to seek professional help:
What Is Knee Pain?
Knee pain is a physical discomfort occurring in or around the knee joint. The knee consists of bones, cartilage, ligaments, and tendons, all of which work together to provide stability. Pain originates from any of these structures when they sustain damage or undergo severe deterioration. Patients may describe the sensation as a dull ache, a sharp localized pain, or a burning feeling, and a precise diagnosis requires a comprehensive physical examination and detailed imaging studies.
What Causes It?
Knee pain can arise from a range of conditions and lifestyle factors. Its causes include:
- Osteoarthritis: This is a degenerative joint disease that is a frequent cause of pain.
- Injuries: Ligament sprains, tendonitis, bursitis, fractures, and torn cartilage are common triggers.
- Lifestyle factors: Excess body weight increases stress on the knee joint, while repetitive movements from sports can also lead to chronic discomfort.
These elements contribute to both acute and chronic pain by affecting the joint’s structure and function.
When Is Professional Help Necessary?
Seeking professional evaluation is necessary when knee pain persists beyond a few weeks, interfering with daily functioning. Swelling, instability, joint locking, or an inability to fully straighten or bend the knee are signs that warrant medical attention. A radiology specialist will perform imaging studies to identify the underlying cause, and early intervention may lead to better outcomes.
What Are the Treatment Options?
Treatment varies depending on the diagnosis, severity, and the patient’s overall health, which a healthcare provider will assess. Conservative approaches include physical therapy, pain medications, and pain injections; these treatments help manage pain and improve joint function. These methods are typically recommended as initial treatment before evaluating more advanced procedures.
Two minimally invasive procedures may be recommended for patients with knee pain who have not responded to conservative care. Genicular artery embolization (GAE) is a procedure in which tiny particles are injected into the arteries supplying the knee to reduce abnormal blood flow, thereby decreasing inflammation and pain. GAE is performed by an interventional radiologist, and it does not require surgery or general anesthesia.
Genicular radiofrequency ablation (GRA) is a technique that uses heat generated by radiofrequency energy to disrupt the nerve signals that transmit pain to the knee. GRA specifically targets the genicular nerves, providing targeted pain relief for patients with chronic pain. Patients typically experience a shorter recovery period, and they can return to normal activities sooner. A specialist will determine which treatment aligns with a patient’s condition and medical history.

Knee pain is not a condition to manage alone; persistent pain, swelling, and mobility limitations are all signs that a professional evaluation is warranted. With advances in minimally invasive procedures such as genicular artery embolization and genicular radiofrequency ablation, effective relief is achievable without the need for major surgery. Consult a qualified specialist to discuss your symptoms and explore the treatment options available to you.
