Knee Pain: Why Can't I Squat? - Orthopedics

More Info

---

Knee pain, particularly the inability to squat without discomfort, can be a frustrating and debilitating issue. Based on your description, it seems you have been experiencing knee pain for an extended period, which has not improved despite taking glucosamine supplements like "維骨力" (Kudona Capsules) for a year. Let's break down the potential causes of your knee pain and explore some treatment options.


Possible Causes of Knee Pain
1. Patellofemoral Pain Syndrome (PFPS): This condition is characterized by pain around the kneecap (patella) and is often exacerbated by activities that put stress on the knee joint, such as squatting. It can result from overuse, muscle imbalances, or alignment issues.

2. Meniscus Injury: Given your history of knee discomfort, a meniscal tear could be a possibility. This type of injury often leads to pain during squatting or twisting motions and can cause a sensation of locking or catching in the knee.

3. Osteoarthritis: Although you mentioned that X-rays did not show any significant issues, early-stage osteoarthritis might not always be visible on imaging. This degenerative joint disease can cause pain, stiffness, and swelling, particularly after periods of inactivity.

4. Tendinitis: Inflammation of the tendons around the knee, such as patellar tendinitis, can also lead to pain during activities like squatting. This condition is often seen in athletes or individuals who engage in repetitive knee movements.

5. Bursitis: Inflammation of the bursae (small fluid-filled sacs that cushion the knee joint) can cause pain and swelling, particularly when bending the knee.


Treatment Options
1. Physical Therapy: Engaging in a structured physical therapy program can help strengthen the muscles around the knee, improve flexibility, and correct any biomechanical issues. A physical therapist can design a personalized exercise regimen that focuses on strengthening the quadriceps, hamstrings, and hip muscles, which are crucial for knee stability.

2. Activity Modification: Avoiding activities that exacerbate your pain, such as deep squatting or jumping, can help reduce symptoms. Gradually reintroducing these activities as your strength and flexibility improve is essential.

3. Pain Management: Over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen can help manage pain and inflammation. However, it's important to use these medications as directed and consult with a healthcare provider if you have concerns about long-term use.

4. Injections: In some cases, corticosteroid injections may be recommended to reduce inflammation and provide temporary relief. Hyaluronic acid injections are another option that may help lubricate the joint.

5. Supplements: While glucosamine and chondroitin are commonly used for joint health, their effectiveness can vary from person to person. If you are concerned about the long-term use of these supplements, it is advisable to discuss this with your healthcare provider.

6. Surgical Options: If conservative treatments fail and your pain significantly impacts your quality of life, surgical options may be considered. This could include arthroscopy to repair any meniscal tears or other structural issues.


Conclusion
It’s essential to approach knee pain with a comprehensive strategy that includes proper diagnosis and treatment. Since you have already consulted with a physician and had X-rays taken, it may be beneficial to seek a second opinion or consult an orthopedic specialist who can perform a more detailed evaluation, possibly including an MRI, to assess soft tissue structures around the knee.

In the meantime, focus on gentle strengthening exercises, maintaining a healthy weight, and avoiding activities that provoke pain. Remember, patience and consistency in your rehabilitation efforts are key to improving your knee function and reducing pain. If your symptoms persist or worsen, do not hesitate to seek further medical advice.
