Non-Painful Knee Lump After Injury: When to Seek Medical Advice? - Orthopedics

A small lump on the knee that does not go away over time but is not painful?


Hello doctor, I had a motorcycle accident a year and a half ago, and I sustained a contusion (abrasion) on my right knee with a large bruise.
At that time, I treated it with Betadine and applied artificial skin.
Now, there is a small lump about the size of a ten-dollar coin in the same area, which is slightly darker in color (I suspect it may be due to the Betadine).
However, this lump is not painful when pressed, and I have no issues walking or exercising with my knee.
I would like to know if there is any need for special treatment since it is not painful.
I checked, and it seems that for cosmetic reasons, I could consider excisional surgery to remove the lump.
If I want to be cautious and get it checked, which specialty should I consult? Thank you.

When it comes to a non-painful lump on the knee following an injury, such as the one you described after your motorcycle accident, there are several factors to consider before deciding whether to seek medical advice.
Firstly, it’s important to understand the nature of the lump. Given that it has been present for a year and a half, and that it is not painful, it is likely a benign condition. Common causes of such lumps can include scar tissue formation, a lipoma (a benign fatty tumor), or a ganglion cyst. The fact that it is not causing any pain or discomfort during movement is a positive sign, suggesting that it may not be a serious issue.

However, there are certain situations where medical evaluation is warranted. If the lump begins to change in size, shape, or color, or if you start to experience pain, swelling, or any other new symptoms, it would be wise to consult a healthcare professional. Additionally, if the lump becomes tender or if you notice any signs of infection, such as redness, warmth, or drainage, you should seek medical attention promptly.

In terms of aesthetic concerns, if the lump is bothersome to you for cosmetic reasons, you may consider discussing options with a healthcare provider. Surgical excision could be an option if the lump is determined to be benign and if its removal is deemed appropriate.
For the evaluation of the lump, you would typically want to consult with an orthopedic specialist or a general surgeon. An orthopedic doctor specializes in conditions related to bones, joints, and soft tissues, making them well-suited to assess any musculoskeletal issues. A general surgeon can also evaluate the lump and discuss potential surgical options if necessary.

During your consultation, the physician may perform a physical examination and could recommend imaging studies, such as an ultrasound or MRI, to better understand the nature of the lump. These imaging techniques can help differentiate between various types of lumps and guide further management.

In summary, while a non-painful lump on the knee that has persisted for a year and a half may not require immediate medical attention, it is essential to monitor it for any changes. If you have concerns about its appearance or if any new symptoms arise, seeking advice from an orthopedic specialist or a general surgeon would be the appropriate next step. Always prioritize your health and well-being, and don’t hesitate to reach out to a healthcare professional if you have any doubts or questions regarding your condition.
