Patella


Hello Doctor: Here’s the situation.
Occasionally, my right knee joint hurts when I bend it.
I went to the hospital for an examination; one doctor said it was gout, while another said it was a sports injury, so I left it unresolved.
Two days ago, my left foot suddenly made a "pop" sound, and afterward, the joint area was very painful.
I went to the hospital for an examination and had an X-ray taken.
The doctor said my patella was misaligned.
The doctor taught me an exercise to do 200 times daily and suggested I could buy a knee brace.
He also mentioned that for maintenance, I could take glucosamine.
When I went to the pharmacy to buy glucosamine, they told me to take it three times a day for three months, and then gradually reduce the dosage while continuing to take it.
Could you please advise me on what I should do?

Hello: Misalignment of the knee (patella) can lead to knee pain, including recurrent subluxation and dislocation.
Sometimes the appearance may not be obvious, and a detailed examination is necessary to determine whether it is caused by muscle asymmetry or skeletal abnormalities.
Abnormal plicae within the knee, osteochondritis dissecans, juvenile rheumatoid arthritis, septic arthritis, osteomyelitis, and synovial osteochondromatosis can also cause knee pain.
Since the femur and tibia in the knee are among the fastest-growing bones in the human body, various benign and malignant bone tumors are commonly found in this area.
Therefore, when adolescents experience persistent pain, swelling, and warmth in the knee, it should not be taken lightly.
In addition to bones, the knee contains many muscles, ligaments, and cartilage.
Thus, for diagnosis, besides medical history, physical examination, and standard X-rays, sometimes additional imaging such as arthrography, arthroscopy, computed tomography (CT), magnetic resonance imaging (MRI), and biopsy are necessary to achieve an accurate diagnosis; only with a correct diagnosis can effective treatment be implemented.

More Info


Patellar dislocation, or dislocation of the kneecap, is a condition that occurs when the patella (kneecap) slips out of its normal position in the groove of the femur (thigh bone). This can lead to significant pain, swelling, and instability in the knee joint. Understanding the management and treatment options for patellar dislocation is crucial for recovery and prevention of future dislocations.


Pain Management
1. Rest and Ice: Initially, after a dislocation, it's important to rest the knee and apply ice to reduce swelling and pain. Ice should be applied for 15-20 minutes every few hours, especially in the first 48 hours after the injury.

2. Medications: Over-the-counter pain relievers such as ibuprofen or acetaminophen can help manage pain and reduce inflammation. If the pain is severe, a doctor may prescribe stronger pain medications.

3. Bracing: A knee brace can provide support and stability to the knee joint, helping to prevent further dislocations. Your doctor may recommend a specific type of brace based on the severity of your injury.


Treatment Options
1. Physical Therapy: Once the initial pain and swelling have decreased, physical therapy is often recommended. A physical therapist can guide you through exercises to strengthen the muscles around the knee, improve flexibility, and restore range of motion. This is crucial for preventing future dislocations.

2. Rehabilitation Exercises: The exercises prescribed by your doctor, such as the one you mentioned doing 200 times a day, are likely aimed at strengthening the quadriceps and stabilizing the patella. Consistency is key in rehabilitation, and it's important to follow your therapist's instructions closely.

3. Patellar Taping: Some patients benefit from patellar taping techniques, which can help keep the patella in place during movement. This can be particularly useful during the rehabilitation phase.

4. Surgery: In cases where dislocations are recurrent or if there is significant damage to the knee structures, surgical intervention may be necessary. Surgical options can include realigning the patella, repairing any damaged ligaments, or tightening the structures that hold the patella in place.


Nutritional Support
You mentioned being advised to take glucosamine. Glucosamine is a supplement that some people take to support joint health. While research on its effectiveness is mixed, it may help some individuals with joint pain. It's generally considered safe, but it's important to discuss with your doctor how long you should take it and the appropriate dosage.


Conclusion
In summary, managing a patellar dislocation involves a combination of rest, ice, pain management, physical therapy, and possibly bracing. Following your doctor's advice on rehabilitation exercises is crucial for recovery. If you experience persistent pain or instability, or if dislocations recur, further evaluation by an orthopedic specialist may be necessary. Always consult with your healthcare provider before starting any new treatment or supplement to ensure it aligns with your specific health needs.
