Knee Pain: Causes, Symptoms, and Treatment Options

Knee pain!!

Hello, doctor.
I would like to ask about my boyfriend's knee.
For some reason, it has been painful for the past month or two.
It feels fine when he walks, but if he sits or stands for too long and then gets up, his knee hurts.
He previously went to the hospital, and the doctor mentioned it might be tendonitis and prescribed medication.
He feels better when taking the medication, but the pain returns when he stops.
What could this condition be? Can you recommend a doctor in Banqiao?

There may be an issue with the articular cartilage between the patella and the femur.
You can consult Dr.
Chen, the orthopedic specialist at Taipei Hospital, New Taipei City Health Department.
An X-ray can be taken to check for any lateral displacement or valgus deformity of the patella.

More Info

Knee pain can be a complex issue with various underlying causes, and understanding these can help in managing the symptoms effectively. Based on your description, it seems your boyfriend has been experiencing knee pain for the past couple of months, particularly after prolonged sitting or standing, which improves with movement but returns upon rest. This pattern of pain is quite common and can be attributed to several factors.

Possible Causes of Knee Pain
1. Tendinitis: As mentioned by the doctor, tendinitis is a common cause of knee pain, especially in individuals who engage in repetitive activities or sports. The pain typically arises from inflammation of the tendons around the knee, often due to overuse. This condition can lead to pain during movement and stiffness after periods of inactivity.

2. Patellofemoral Pain Syndrome (PFPS): This condition, often referred to as "runner's knee," is characterized by pain around the kneecap (patella). It can be exacerbated by activities such as climbing stairs, squatting, or sitting for long periods. PFPS is often related to muscle imbalances or improper alignment of the knee joint.

3. Osteoarthritis: While your boyfriend is relatively young, early signs of osteoarthritis can still occur, especially if there is a history of knee injuries or overuse. This degenerative joint disease can cause pain, swelling, and stiffness, particularly after periods of inactivity.

4. Meniscus Tear: A tear in the knee's cartilage (meniscus) can cause pain, especially when twisting or rotating the knee. Symptoms may include swelling, stiffness, and difficulty fully bending or straightening the knee.

5. Bursitis: Inflammation of the bursae, small fluid-filled sacs that cushion the knee joint, can lead to localized pain and swelling. Bursitis often results from repetitive motion or prolonged pressure on the knee.

Symptoms to Monitor
- Swelling or Stiffness: Observe if there is any swelling around the knee joint or if it feels stiff after sitting or standing for a long time.

- Pain Location: Note where the pain is most intense. Is it around the kneecap, on the sides, or behind the knee?
- Range of Motion: Check if there are any limitations in bending or straightening the knee.

- Pain Triggers: Identify activities that worsen the pain, such as climbing stairs, squatting, or sitting for extended periods.

Treatment Options
1. Rest and Activity Modification: Encourage your boyfriend to rest the knee and avoid activities that exacerbate the pain. Gradually reintroducing activities can help assess tolerance.

2. Physical Therapy: A physical therapist can design a tailored exercise program to strengthen the muscles around the knee, improve flexibility, and correct any biomechanical issues.

3. Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) can help reduce pain and inflammation. If prescribed, it's essential to follow the dosage instructions.

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

5. Knee Braces or Supports: Using a knee brace can provide additional support and stability during activities.

6. Injections: In some cases, corticosteroid injections may be recommended to reduce inflammation and provide temporary relief.

7. Surgery: If conservative treatments fail and the pain persists, surgical options may be considered, especially in cases of significant structural damage.

When to Seek Further Medical Attention
If the pain persists despite conservative treatment, worsens, or is accompanied by significant swelling, redness, or inability to bear weight on the knee, it is crucial to seek further evaluation from an orthopedic specialist. They may recommend imaging studies, such as X-rays or MRI, to assess the knee's condition more thoroughly.

In conclusion, knee pain can stem from various causes, and understanding the specific symptoms and triggers is essential for effective management. Encourage your boyfriend to follow up with a healthcare provider if his symptoms do not improve, as early intervention can often lead to better outcomes.
