Knee Pain After Injury: Causes and When to Seek Help - Orthopedics

Knee Consultation Inquiry


Dear Dr.
Shi,
I had a car accident at the end of 2017, injuring my right knee (with bleeding and bruising).
I went to an orthopedic specialist for an X-ray, and the doctor stated that there were no issues with my right knee joint (such as fractures, cracks, or dislocations).
However, I have since experienced a couple of issues: first, when kneeling on my right knee, I feel tenderness when pressing against the floor; second, I have recently noticed pain in the area just below my right knee when I exert force while standing up from a seated position.

I would like to ask you:
Q1.
Given that the X-ray showed no issues with my right knee joint, what do you think could be causing the tenderness when kneeling on the floor?
Q2.
Recently, I have noticed pain in the area just below my right knee when I exert force while standing up.
In your opinion, what could be causing this pain?
Q3.
Should I seek immediate medical evaluation and treatment, or can I continue to monitor the situation?
Thank you, Dr.
Shi.

The kneecap, also known as the patella, has synovial tissue present on its anterior surface.
Sometimes, when kneeling and making contact, it can cause pain due to inflammation.
Additionally, after a collision, there may be a period of pain when transitioning from sitting to standing, as the patellar ligament pulls on the area below the patella, which can also be painful due to tendonitis.
It is advisable to continue monitoring the condition, and if there is no improvement, seek a physician for further evaluation.

Knee pain after an injury can be a complex issue, especially when the initial imaging, such as X-rays, shows no obvious fractures or dislocations. Based on your description, let's address your questions systematically.


Q1: Causes of Pain When Kneeling
The pain you experience when kneeling on your right knee could be attributed to several factors. One common cause is prepatellar bursitis, which is inflammation of the bursa located in front of the kneecap. This condition can occur due to trauma, repetitive kneeling, or prolonged pressure on the knee. Another possibility is patellar tendinitis, which involves inflammation of the tendon connecting the kneecap to the shinbone. This can cause pain during activities that put pressure on the knee, such as kneeling.

Additionally, you might be experiencing chondromalacia patellae, a condition where the cartilage on the underside of the kneecap deteriorates and softens, leading to pain during movement or pressure. Since you mentioned that there was bleeding and bruising at the time of the injury, it’s also possible that there was some soft tissue damage that didn’t show up on the X-ray but could still be causing discomfort.


Q2: Pain When Standing Up from a Seated Position
The pain you feel when standing up from a seated position could be related to several issues as well. One potential cause is patellofemoral pain syndrome, which is characterized by pain around the kneecap and can be exacerbated by activities that involve bending the knee, such as standing up from a seated position. This syndrome often results from muscle imbalances or weakness, particularly in the quadriceps, which can lead to improper tracking of the kneecap.

Another possibility is osteoarthritis, especially if you have a history of knee injuries. Although your X-ray did not show any acute issues, it’s important to consider that cartilage wear and tear can develop over time, leading to pain during weight-bearing activities.


Q3: When to Seek Medical Attention
Given that you are experiencing persistent pain and discomfort, it is advisable to seek further medical evaluation. While some knee pain can improve with rest, ice, compression, and elevation (the RICE method), your symptoms suggest that there may be underlying issues that require more than just conservative management.

A follow-up with an orthopedic specialist is recommended. They may suggest further imaging studies, such as an MRI, which can provide a more detailed view of the soft tissues, including ligaments, tendons, and cartilage. This can help identify any injuries that were not visible on the X-ray.

In the meantime, consider modifying your activities to avoid positions that exacerbate your pain. Gentle stretching and strengthening exercises for the muscles around the knee may also be beneficial, but these should be done under the guidance of a healthcare professional to avoid further injury.


Conclusion
In summary, knee pain after an injury can stem from various causes, including bursitis, tendinitis, or cartilage issues. Given your symptoms, it is prudent to seek further evaluation to determine the exact cause and appropriate treatment. Early intervention can help prevent further complications and facilitate a quicker recovery. Remember to listen to your body and avoid activities that cause pain until you have a clearer understanding of your condition.
