Meniscus-related issues


Hello doctor, I previously twisted my knee, and now after sitting for a while, my knee starts to hurt.
Walking also causes discomfort and soreness.
When going up stairs, I experience pain on the outer back side of my right knee, but it doesn't lock up while walking.
Additionally, my knee tends to rotate excessively and feels a bit unstable.
What could be wrong with my knee?

It sounds like there may be an issue with the ligaments, likely a tear in the meniscus, which often presents with symptoms such as locking or swelling in the joint.
If the symptoms persist, it is important to consult a physician for an evaluation.

Knee pain, particularly related to the meniscus, can be a complex issue that arises from various causes. The meniscus is a C-shaped cartilage in the knee that acts as a cushion between the femur (thigh bone) and the tibia (shin bone). It plays a crucial role in stabilizing the knee joint, absorbing shock, and distributing weight. When the meniscus is injured, it can lead to pain, swelling, and instability in the knee.

Based on your description, it seems that your knee pain may be associated with a meniscal injury, especially considering your history of twisting the knee. Here are some potential causes and solutions for your symptoms:

Causes of Meniscus-Related Knee Pain:
1. Meniscal Tear: This is the most common injury associated with knee pain. It can occur due to a sudden twist or turn, especially when the foot is planted. Symptoms often include pain, swelling, and a sensation of the knee "catching" or "locking."
2. Degenerative Changes: Over time, the meniscus can wear down due to age or repetitive stress, leading to degenerative tears. This is more common in older adults and can cause chronic knee pain and instability.

3. Joint Instability: If the meniscus is damaged, it can lead to instability in the knee joint. This may cause the knee to feel like it is giving way or not supporting your weight properly.

4. Associated Injuries: Sometimes, a meniscal tear can occur alongside other injuries, such as ligament tears (e.g., ACL or MCL injuries), which can exacerbate symptoms and lead to further instability.


Solutions and Treatment Options:
1. Rest and Activity Modification: It is crucial to rest the knee and avoid activities that exacerbate the pain, such as running or jumping. Modify your daily activities to reduce strain on the knee.

2. Ice Therapy: Applying ice to the knee for 15-20 minutes several times a day can help reduce swelling and alleviate pain.

3. Physical Therapy: A physical therapist can design a rehabilitation program that focuses on strengthening the muscles around the knee, improving flexibility, and enhancing stability. Exercises may include quadriceps and hamstring strengthening, as well as balance training.

4. Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) can help reduce pain and inflammation. Always consult with a healthcare provider before starting any medication.

5. Bracing: A knee brace can provide additional support and stability, especially during activities that may stress the knee.

6. Injections: In some cases, corticosteroid injections may be recommended to reduce inflammation and pain. Hyaluronic acid injections may also be considered to lubricate the joint.

7. Surgery: If conservative treatments fail and the pain persists, surgical options may be necessary. This could involve arthroscopic surgery to repair or remove the damaged portion of the meniscus.

8. Lifestyle Modifications: Maintaining a healthy weight can reduce stress on the knee joint. Engaging in low-impact exercises, such as swimming or cycling, can help maintain fitness without aggravating the knee.


Conclusion:
Given your symptoms of pain, instability, and discomfort during certain movements, it is advisable to consult with an orthopedic specialist. They may recommend imaging studies, such as an MRI, to assess the condition of the meniscus and other structures in the knee. Early diagnosis and appropriate management are key to preventing further damage and ensuring a successful recovery. Remember, each case is unique, and a tailored approach to treatment will yield the best results.
