Knee Pain: Causes, Symptoms, and Treatment Options - Orthopedics

Knee pain can be a complex issue, often stemming from various causes, including injuries, degenerative changes, or overuse. Based on your description, it seems you have been experiencing symptoms for three years following an injury to the inner side of your knee. The tightness, occasional swelling, and sounds (like popping or cracking) you hear when moving your knee are common complaints that can indicate underlying issues with the knee joint.


Possible Causes of Your Knee Pain
1. Cartilage Damage: The sounds you describe, along with the feeling of tightness and occasional swelling, could suggest some degree of cartilage damage. The cartilage acts as a cushion between the bones in your knee, and if it becomes worn down or damaged, it can lead to pain and instability.

2. Meniscus Injury: The meniscus is a C-shaped cartilage in your knee that helps absorb shock and stabilize the joint. If you experienced a significant impact during your injury, it’s possible that you may have sustained a meniscal tear, which can lead to symptoms like pain, swelling, and a sensation of the knee giving way.

3. Ligament Strain: The ligaments in your knee, particularly the medial collateral ligament (MCL), could be strained or partially torn from the initial injury. This can lead to ongoing pain and instability, especially when engaging in activities that put stress on the knee.

4. Patellar Tracking Disorder: You mentioned that your kneecap feels like it slides when you stand up. This could indicate a patellar tracking disorder, where the kneecap does not move smoothly in its groove during knee movement, leading to pain and sounds.

5. Osteoarthritis: While your X-rays and MRI did not show any abnormalities, it’s important to note that early signs of osteoarthritis may not always be visible on imaging. Osteoarthritis can develop over time, especially after an injury, leading to pain, swelling, and decreased range of motion.


Treatment Options
1. Physical Therapy: Continuing with physical therapy is crucial. A physical therapist can provide targeted exercises to strengthen the muscles around your knee, improve flexibility, and enhance stability. This can help alleviate some of the pressure on the knee joint and improve function.

2. Activity Modification: It’s wise to avoid activities that exacerbate your symptoms, such as running or jumping. Instead, focus on low-impact exercises like swimming or cycling, which can help maintain fitness without putting undue stress on your knee.

3. Pain Management: Over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) can help manage pain and inflammation. However, consult with your healthcare provider before starting any medication.

4. Injections: If conservative treatments do not provide relief, corticosteroid injections may be considered to reduce inflammation. In some cases, hyaluronic acid injections can help lubricate the joint.

5. Surgical Options: If conservative management fails and your symptoms significantly impact your quality of life, surgical options may be explored. This could include arthroscopy to repair any cartilage or meniscal damage or realigning the patella if tracking issues are present.


Conclusion
Given the duration and nature of your symptoms, it is essential to continue monitoring your knee's condition. Regular follow-ups with your healthcare provider, including potential repeat imaging if symptoms worsen, can help ensure that any developing issues are addressed promptly. Engaging in a comprehensive rehabilitation program and being mindful of your knee's limits will be key to managing your symptoms effectively. Always consult with a healthcare professional before making any significant changes to your treatment plan.
