Pain in the front of the knee following an accidental impact?
Hello doctor, about a week ago I accidentally fell while riding my bicycle and hit my left knee directly against the ground.
After applying ice and resting for two days, I resumed cycling.
Now, I feel a constant friction sensation when bending my knee, and there is pain when going up and down stairs.
The discomfort only lessens when my knee is fully extended and when I wear a brace.
What could be the possible causes? I am currently abroad and will be here for a while longer; I would like to know if it is necessary to see a doctor.

Hello, you can try applying a warm compress first.
Additionally, please avoid any movements that cause pain for the time being.
If the situation does not improve, please visit the orthopedic clinic for an examination.
Thank you.

More Info
Knee pain following a fall, especially after direct impact, can be concerning and warrants careful consideration. Based on your description, it seems that you are experiencing persistent discomfort and a sensation of friction when bending your knee, along with pain during activities such as climbing stairs. These symptoms could indicate several potential issues, and understanding them can help you decide whether to seek medical attention.
Potential Causes of Your Symptoms
1. Soft Tissue Injury: The impact from your fall could have caused damage to the ligaments, tendons, or cartilage around the knee. Common injuries include sprains or strains of the ligaments (like the ACL or MCL) or damage to the meniscus, which is the cartilage that cushions the knee joint.
2. Contusion: A direct blow to the knee can lead to a bruise (contusion) that may cause swelling and pain. This can also lead to stiffness and a feeling of tightness in the joint.
3. Patellar Injury: The patella (kneecap) may have been affected during the fall, leading to conditions such as patellar tendinitis or even a fracture, although fractures are less common without severe trauma.
4. Joint Effusion: Sometimes, following an injury, fluid can accumulate in the knee joint, leading to swelling and discomfort. This condition is often referred to as "water on the knee."
5. Osteoarthritis: If you have a history of knee issues or if you are older, the impact could exacerbate underlying osteoarthritis, leading to increased pain and stiffness.
When to Seek Medical Attention
Given your symptoms, it is advisable to consider seeing a healthcare professional if you experience any of the following:
- Persistent Pain: If the pain does not improve with rest, ice, and over-the-counter pain medications after a few days.
- Swelling: If you notice significant swelling or if the knee feels warm to the touch, indicating possible inflammation or infection.
- Limited Range of Motion: If you find it increasingly difficult to bend or straighten your knee.
- Instability: If you feel that your knee is unstable or gives way when you try to put weight on it.
- Locking Sensation: If you experience a sensation that the knee is "locking" or catching during movement.
Recommendations
1. Rest and Ice: Continue to rest the knee and apply ice to reduce swelling. Avoid activities that exacerbate the pain, such as cycling or climbing stairs.
2. Compression and Elevation: Use a knee brace or wrap to provide support and elevate the leg to help reduce swelling.
3. Over-the-Counter Pain Relief: Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen can help manage pain and inflammation.
4. Physical Therapy: If symptoms persist, consider consulting a physical therapist who can provide exercises to strengthen the knee and improve flexibility.
5. Medical Evaluation: If your symptoms do not improve or worsen, seek medical attention. A healthcare provider may perform a physical examination and possibly imaging studies (like an X-ray or MRI) to assess for any underlying injuries.
Conclusion
While it may be tempting to dismiss your symptoms, especially if they seem manageable, it is crucial to listen to your body. Knee injuries can sometimes lead to long-term issues if not addressed properly. If you are still experiencing discomfort after a week, it would be wise to consult with a healthcare professional, even if you are currently abroad. Early intervention can prevent further complications and help you return to your normal activities more quickly.
