The knee often feels uncomfortable, but it does not affect walking or daily activities?
Hello, Doctor! After running a 25-kilometer marathon last October, I've experienced knee pain whenever I run more than 5 kilometers.
I took a break for about three months during which my knee felt mostly fine, but recently, even when I'm not running, my knee has been uncomfortable.
While it doesn't significantly affect my daily life, it is quite bothersome and sometimes disrupts my sleep.
Additionally, if I walk excessively, my knee starts to hurt.
There was a month where I could walk a lot without any issues, but recently the discomfort has returned.
Since I've been in Korea for the past six months, I visited a hospital there and had an X-ray taken.
The doctor said there was nothing major wrong and advised me to rest for recovery.
However, I've recently been feeling a slight discomfort in my knee again, which is hard to describe.
I would appreciate your guidance, thank you!

Running a marathon places significant stress on the knee joints, which can lead to cartilage wear.
The patella, in particular, is more susceptible to symptoms under greater pressure, such as during squatting, climbing stairs, or running.
Early X-rays may not reveal any abnormalities, but repeated stress can result in degenerative changes.
Currently, the focus should be on protective measures for the cartilage.

More Info
Knee discomfort, especially after running or engaging in physical activities, can be a common issue among athletes and active individuals. Given your history of running a marathon and the subsequent discomfort you've experienced, it's essential to understand the potential causes and when to seek medical help.
Understanding Your Symptoms
1. Post-Running Pain: Experiencing knee pain after running, particularly after long distances like 25 kilometers, can be attributed to several factors, including overuse injuries, patellar tendinitis, iliotibial band syndrome, or even early signs of osteoarthritis. The fact that your pain recurs after running distances over 5 kilometers suggests that your knee may not be fully recovered from the initial strain.
2. Rest and Recovery: You mentioned taking a three-month break, during which your knee felt better. This indicates that your symptoms may be related to overuse rather than a structural issue. However, the return of discomfort, even during daily activities, suggests that there may be underlying issues that need addressing.
3. X-ray Findings: The X-ray results you received in Korea indicated no significant problems. While X-rays are excellent for identifying fractures or significant bone issues, they may not reveal soft tissue injuries, such as ligament sprains, meniscus tears, or cartilage damage. If your symptoms persist, further imaging, such as an MRI, may be warranted to assess the soft tissues around the knee.
When to Seek Help
You should consider seeking medical attention if you experience any of the following:
- Persistent Pain: If your knee discomfort continues to interfere with your daily activities or sleep, it’s a sign that further evaluation is necessary.
- Swelling: Any noticeable swelling or changes in the knee joint should be assessed by a healthcare professional.
- Instability: If you feel like your knee is giving way or if you have difficulty bearing weight, this could indicate a more serious injury.
- Limited Range of Motion: If you find it difficult to fully extend or flex your knee, this warrants further investigation.
Recommendations for Management
1. Rest and Ice: Continue to rest your knee and apply ice to reduce any inflammation. Avoid activities that exacerbate your symptoms, particularly running or prolonged walking.
2. Physical Therapy: Engaging in physical therapy can help strengthen the muscles around your knee, improve flexibility, and address any biomechanical issues contributing to your discomfort.
3. Cross-Training: While running may aggravate your knee, consider low-impact activities such as swimming or cycling, which can help maintain your fitness without putting undue stress on your knee.
4. Gradual Return to Running: If you plan to return to running, do so gradually. Start with shorter distances and incorporate walking intervals to gauge your knee's response.
5. Knee Support: Using a knee brace or support during activities may provide additional stability and help alleviate discomfort.
6. Consultation with a Specialist: If your symptoms persist despite conservative management, consider consulting an orthopedic specialist. They may recommend further imaging or interventions based on your specific condition.
Conclusion
Knee discomfort after running can stem from various causes, and while rest and conservative management are often effective, persistent symptoms should not be ignored. Given your history and current symptoms, it would be prudent to seek further evaluation if your discomfort continues. Early intervention can prevent more serious injuries and help you return to your desired level of activity safely.
