Knee pain is a common complaint that affects people of all ages. It may start suddenly after an injury or as a mild discomfort that slowly worsens. Chronic pain is long-term pain, swelling, or sensitivity in one or both knees. Here are some common causes and treatments for chronic knee pain:
What Are the Causes of Knee Pain?
The knee is a complex joint, and many issues may lead to pain. Injuries are a frequent source of knee problems. Torn cartilage, like a meniscus tear, or a ruptured ligament, such as an ACL injury, can cause significant discomfort. Tendinitis, an inflammation of the tendons surrounding the knee, also results from overuse or injury.
Mechanical problems are another category of causes. A dislocated kneecap creates immediate pain and instability. Iliotibial (IT) band syndrome occurs when the ligament extending from your hip to your shin becomes tight and rubs against your femur. Pain in your hip or foot can cause you to change your gait, which places more stress on your knee joint and leads to pain.
Various types of arthritis also cause chronic knee pain. Osteoarthritis involves the wear and tear of cartilage in the knee, leading to pain and stiffness. Rheumatoid arthritis is an autoimmune condition where the body’s immune system attacks the joints, including the knees. Gout is caused by the buildup of uric acid crystals in the joints.
When Should I Seek Treatment?
It is a good idea to seek a medical evaluation when knee pain persists. You may want to schedule an appointment if you cannot bear weight on your knee or feel as if your knee is unstable. Significant swelling, an inability to fully extend or flex your knee, or a visible deformity are also signs that you might benefit from seeing a healthcare provider. If you have a fever along with redness and swelling in your knee, a prompt medical check is advisable.
What Are My Treatment Options?
Treatment for knee pain varies depending on the cause, but for persistent issues, your doctor might suggest minimally invasive procedures. These treatments target the source of your pain, offering relief when other methods haven’t worked. Some options include:
- Genicular Nerve Radiofrequency Ablation (RFA): This procedure targets the nerves around your knee that send pain signals to your brain. A needle is used to deliver radiofrequency waves, which gently heat and disrupt the nerves. The goal is to stop them from transmitting pain signals, providing you with long-lasting relief without surgery.
- Genicular Artery Embolization (GAE): If your pain is linked to inflammation in the knee joint lining, GAE may be an effective treatment. A specialist injects particles into the genicular arteries that supply blood to the inflamed areas. This reduces blood flow, which decreases inflammation and alleviates pain.
Work With a Radiology Specialist
Understanding the source of your chronic knee pain is the first step toward finding relief. A radiology specialist uses advanced imaging to provide a clear and accurate diagnosis of your knee joint’s condition. This allows your healthcare team to develop a targeted treatment plan for your specific needs. Contact a radiologist today to schedule your consultation and learn more about your diagnostic options.
