Meniscus degeneration and medial collateral ligament injury?


Hello Dr.
Shen,
A month ago, after finishing a boxing aerobic workout, I noticed pain on the inner side of my right knee the next day.
During the workout, there was no external impact, but there were many movements involving deep knee bends and rotational kicks.
Initially, the location of the pain seemed similar to the pain I experienced while doing breaststroke swimming.
I consulted an orthopedic specialist who only performed an X-ray and diagnosed me with significant wear of the medial meniscus, stating that less than half remains (approximately in the second or third stage).
They indicated that overuse of the knee has led to inflammation and recommended rehabilitation (infrared therapy, heat application, and electrical stimulation), along with anti-inflammatory pain medication and topical patches.
However, after a month, there has been no improvement, and now my left knee has also started to feel uncomfortable.

Last week, I visited a traditional Chinese medicine practitioner who, after assessing my pain points, suggested a medial collateral ligament injury and noted poor circulation in my lower limbs.
Despite acupuncture and relaxation massage, I have not seen any improvement.
Currently, the condition of both knees fluctuates; there is no severe pain, but there is a noticeable discomfort, and sometimes activities like walking or going up and down stairs cause pain.
I have rested for a month without engaging in any intense exercise and have been doing leg raises to strengthen my quadriceps.
I have a few questions:
1.
If it is just inflammation, why has there been no improvement after a month of rehabilitation, medication, and traditional Chinese medicine?
2.
Is it possible that there are other conditions that cannot be diagnosed with just an X-ray? Can a diagnosis of inflammation be made solely based on X-ray findings of cartilage wear without physical examination or palpation? I am very concerned about the possibility of misdiagnosis and delayed treatment.
3.
Can I continue to engage in slightly high-impact activities such as aerobic dance, boxing, or jogging? I truly love exercising and would like to know when I can resume my workouts! Thank you, doctor.

Hello, netizen: The knee is the largest joint in the human body, and it bears a significant amount of load due to its high level of activity.
There are many causes and conditions associated with knee pain, including ligament sprains, tendon strains, joint inflammation, such as osteoarthritis, gout, and more.
Based on your description, it seems more like pain caused by a sports injury, which is generally referred to as inflammation.
The duration of the pain is related to your rest and treatment, and symptoms can persist and be bothersome for a long time.
Following your physician's instructions regarding anti-inflammatory medication, rehabilitation, and traditional Chinese medicine may be beneficial for you.
Temporarily reduce your level of physical activity until you have fully recovered, and then gradually return to your original level of exercise.
Wishing you good health.

Understanding meniscus wear and medial ligament injury in athletes is crucial for effective management and recovery. Based on your description, it seems you are experiencing a complex situation involving both the meniscus and possibly the medial collateral ligament (MCL) in your right knee, compounded by a lack of improvement despite various treatment modalities.


1. Understanding the Symptoms and Diagnosis
The symptoms you describe—pain on the inner side of the knee, particularly after activities involving bending and twisting—are classic indicators of meniscus injuries or MCL strains. The meniscus serves as a cushion between the femur and tibia, and wear can lead to pain, swelling, and decreased mobility. The fact that you have been diagnosed with significant meniscal wear (stage two or three) suggests that there is indeed a degenerative process occurring, likely exacerbated by repetitive stress from your activities.

The medial collateral ligament (MCL) is crucial for stabilizing the knee, especially during lateral movements. If your symptoms align with MCL injury, it could explain the discomfort you are experiencing, particularly if there is associated swelling or instability.


2. Why Treatment May Not Be Effective
The lack of improvement after a month of rehabilitation, anti-inflammatory medications, and alternative therapies can be frustrating. Several factors could contribute to this situation:
- Severity of Injury: If the meniscal damage is significant, conservative treatments may not suffice. In some cases, surgical intervention may be necessary to repair or remove damaged tissue.


- Misdiagnosis: Relying solely on X-rays can sometimes lead to missed diagnoses. X-rays are excellent for visualizing bone structures but do not provide detailed images of soft tissues like cartilage or ligaments. An MRI is often recommended for a more comprehensive evaluation of soft tissue injuries.

- Inflammation and Pain Management: Chronic inflammation can persist even with treatment. If the underlying cause (e.g., mechanical instability, improper biomechanics) is not addressed, symptoms may continue.


3. Potential for Other Conditions
Given that your left knee has started to show discomfort as well, it raises the possibility of compensatory issues due to altered gait mechanics or bilateral knee problems. Conditions like patellofemoral pain syndrome or even early osteoarthritis could also be contributing factors. A thorough physical examination and possibly imaging studies beyond X-rays (like MRI) would be beneficial to rule out these conditions.


4. Returning to High-Impact Activities
Regarding your question about resuming high-impact activities like aerobic dance, boxing, or jogging, it is essential to approach this cautiously. Engaging in high-impact sports without addressing the underlying issues could exacerbate your condition. Here are some recommendations:
- Consult a Specialist: A sports medicine physician or orthopedic surgeon can provide a more detailed assessment and may recommend an MRI to evaluate the soft tissues more accurately.

- Gradual Return: If cleared by a healthcare professional, consider starting with low-impact activities (e.g., swimming, cycling) that do not place excessive stress on the knees. Gradually reintroduce higher-impact activities as tolerated.

- Strengthening and Flexibility: Continue with your quadriceps strengthening exercises, but also incorporate flexibility and stability training to support the knee joint.

- Listen to Your Body: Pay attention to pain signals. If certain movements or activities cause discomfort, it may be best to modify or avoid them until you have fully recovered.


Conclusion
In summary, your situation requires careful evaluation and possibly further imaging to ensure an accurate diagnosis. While it is understandable to want to return to your beloved activities, prioritizing your knee health is crucial for long-term athletic performance. Working closely with healthcare professionals will help you navigate this recovery process effectively.
