Knee discomfort?


Hello Doctor: I usually play badminton, and last Wednesday I suddenly felt discomfort in my right knee.
There wasn't a significant pain, but rather a sensation of weakness and tightness in the knee, which made walking and going up and down stairs difficult.
Sometimes while playing, I would experience a tightening of the knee and a brief loss of sensation (though this was very short-lived and infrequent).
After seeing an orthopedic doctor, he determined that it wasn't a bone issue but rather a soft tissue problem.
He prescribed a topical ointment, anti-inflammatory medication, and a muscle relaxant.
After a week, my mobility has improved (walking is much easier), but my knee has become very sore, weak, and difficult to exert force.
I would like to ask the doctor what this issue might be.
Is this a normal symptom during the healing process of inflammation? P.S.
I heard from a classmate that soft tissue issues require an MRI for examination.
Given my symptoms, should I go back to that doctor to express my concerns? Thank you for your response.

Hello: If the physician's physical examination does not reveal any significant discomfort or pain, there is no urgent need for an MRI, as it is likely caused by soft tissue inflammation or strain.
In cases of severe soft tissue injury, treatment may take up to two months for recovery.
Remember to return for a follow-up appointment, and the physician will provide appropriate management based on the situation.
Thank you!

More Info


Knee discomfort can arise from various causes, including soft tissue injuries, ligament strains, and even underlying conditions such as osteoarthritis or tendinitis. In your case, it seems that you have experienced a sudden onset of tightness and discomfort in your right knee after playing badminton, which is not uncommon in sports that involve quick lateral movements and sudden stops.

The sensation of tightness and the inability to exert force on the knee could indicate a soft tissue injury, such as a strain of the muscles or ligaments surrounding the knee joint. The fact that you experienced a brief loss of sensation in the knee during play could suggest that there may have been a temporary impingement or irritation of the nerves or blood vessels in that area.
Your orthopedic doctor’s assessment that it is not a bone issue but rather a soft tissue problem is consistent with your symptoms. The treatment plan involving topical ointments, anti-inflammatory medications, and muscle relaxants is appropriate for managing soft tissue injuries. These medications can help reduce inflammation and alleviate pain, allowing for improved mobility.

After a week of treatment, if you are noticing improvement in your ability to walk but still experiencing soreness and weakness in the knee, it may indicate that your soft tissues are still healing. It is not uncommon for the knee to feel weak or "soft" during the recovery phase, especially if there has been any inflammation or muscle guarding. This is often a normal part of the healing process, as the body works to repair damaged tissues.

However, if your symptoms persist or worsen, it would be advisable to follow up with your orthopedic doctor. You mentioned that your classmates suggested an MRI for soft tissue issues. While MRIs can provide detailed images of soft tissues, they are typically reserved for cases where there is a suspicion of significant injury, such as a ligament tear or meniscus injury. If your doctor believes that your symptoms are improving and that there is no indication of a more serious injury, they may not feel an MRI is necessary at this time.

In summary, here are some recommendations for your situation:
1. Monitor Symptoms: Keep track of your symptoms. If you notice increased pain, swelling, or instability in the knee, it would be wise to return to your doctor.

2. Rest and Ice: Continue to rest the knee and apply ice to reduce any swelling. Avoid activities that exacerbate the discomfort, such as jumping or running.

3. Physical Therapy: Consider asking your doctor about physical therapy. A physical therapist can provide exercises to strengthen the muscles around the knee and improve stability.

4. Gradual Return to Activity: Once your symptoms improve, gradually return to your regular activities. Start with low-impact exercises and slowly increase intensity as tolerated.

5. Follow-Up: If you continue to experience discomfort or if your knee feels unstable, schedule a follow-up appointment with your orthopedic doctor. They can reassess your condition and determine if further imaging or intervention is necessary.

In conclusion, while it is common to experience some discomfort during the healing process of a soft tissue injury, persistent or worsening symptoms warrant further evaluation. Your orthopedic doctor is the best resource for determining the next steps in your treatment plan.
