Knee Pain: Causes and When to Seek Medical Attention - Orthopedics

Knee pain can be a complex issue, often stemming from various causes, particularly when it is localized to one side, as you described. Understanding the underlying reasons for your knee pain is crucial in determining whether you should seek medical attention or if it might resolve on its own.


Common Causes of Knee Pain
1. Overuse Injuries: Even if you feel you haven't overexerted yourself, activities like running and dancing can lead to overuse injuries. These injuries often manifest as tendonitis or bursitis, especially if there are repetitive movements involved, such as squatting or jumping.

2. Patellar Tendonitis: This condition, often referred to as "jumper's knee," occurs when the tendon connecting the kneecap to the shinbone becomes inflamed. It can cause pain just below the kneecap, particularly during activities that involve jumping or squatting.

3. Meniscus Tear: The meniscus is a cartilage that acts as a cushion between your thigh bone and shin bone. A tear can occur during twisting motions or heavy lifting, leading to pain, swelling, and difficulty moving the knee.

4. Ligament Injuries: Injuries to the ligaments, such as the anterior cruciate ligament (ACL) or medial collateral ligament (MCL), can also cause localized pain. These injuries often occur during sudden stops or changes in direction.

5. Patellofemoral Pain Syndrome: This condition is characterized by pain around the kneecap and can be exacerbated by activities like squatting or climbing stairs. It is often due to muscle imbalances or improper tracking of the kneecap.

6. Osteoarthritis: While more common in older adults, osteoarthritis can develop in younger individuals, especially if there is a history of knee injuries. It leads to the degeneration of cartilage and can cause pain during movement.


When to Seek Medical Attention
Given that your pain is localized to one side and occurs during specific movements, it is advisable to monitor your symptoms closely. Here are some guidelines on when to seek medical attention:
- Persistent Pain: If the pain does not improve with rest, ice, compression, and elevation (RICE) after a few days, it may be time to consult a healthcare professional.


- Swelling or Bruising: If you notice significant swelling, bruising, or warmth around the knee, these could be signs of a more serious injury that requires medical evaluation.

- Difficulty Moving the Knee: If you experience a reduced range of motion or if the knee feels unstable, it is essential to seek medical advice.

- Pain During Rest: If the pain persists even when you are not active, this could indicate a more severe underlying issue.

- History of Injury: If you have previously injured your knee or have a history of knee problems, it is wise to consult a doctor sooner rather than later.


Diagnostic Approaches
If you decide to see a doctor, they may recommend imaging studies such as X-rays or MRI to assess the condition of your knee. X-rays can help rule out fractures or arthritis, while an MRI can provide a detailed view of soft tissues, including ligaments and cartilage.


Conclusion
In summary, while it is possible that your knee pain may resolve with conservative measures, it is essential to listen to your body. If the pain persists or worsens, seeking medical attention is the best course of action. Early diagnosis and treatment can prevent further complications and help you return to your activities more quickly. Remember to rest, apply ice, and avoid aggravating activities until you have a clearer understanding of the cause of your pain.
