Do Knee Bone Spurs Require Arthroscopic Surgery? A Patient's Dilemma - Orthopedics

Is arthroscopic surgery necessary for knee bone spurs?


Hello Doctor: My mother is 54 years old.
Two years ago, she fell and hit the inner side of her right knee.
At that time, she did not receive ongoing treatment, thinking it was just a regular bruise.
However, now her knee sometimes hurts, making it difficult for her to bend it and apply force.
She went to Hospital A for an examination, where the doctor said that the X-ray showed bone spurs on the inner side of the knee and a small piece of bone outside the knee tissue.
Additionally, there was a sound during palpation of the knee, and the doctor recommended arthroscopic surgery to prevent recurrent inflammation.
Concerned, my mother went to another hospital for a check-up.
The doctor at Hospital B said that the X-ray showed bone spurs (but did not capture the small piece of bone outside the knee tissue) and advised against surgery, suggesting that she take anti-inflammatory medication instead and return for a follow-up in a month.
I would like to ask the doctor if surgery is necessary for the bone spur issue.
In my mother's situation, which doctor's advice should we trust? What kind of treatment should she pursue?

Typically, knee bone spurs do not require arthroscopic surgery, as many studies have shown that it is not very helpful, unless the bone spur is loose within the joint and causes locking of the joint's movement, in which case surgery may be necessary.
Therefore, the opinion of the second physician is more accurate; continuing medication treatment is sufficient.

More Info


Knee bone spurs, also known as osteophytes, are bony projections that develop along the edges of bones, often in response to joint damage or degeneration. In your mother's case, the presence of bone spurs in conjunction with her history of knee trauma suggests that there may be underlying issues, such as osteoarthritis or other degenerative changes, that could be contributing to her symptoms of pain and limited mobility.

When considering whether arthroscopic surgery is necessary, it is important to evaluate several factors:
1. Severity of Symptoms: If your mother is experiencing significant pain, swelling, and functional limitations (such as an inability to bend her knee or bear weight), these symptoms may indicate that conservative treatments are insufficient. In such cases, surgery may be warranted to alleviate pain and restore function.

2. Imaging Findings: The X-ray results showing bone spurs and possibly loose bodies (the small piece of bone mentioned) can contribute to joint irritation and inflammation. If these loose bodies are causing mechanical symptoms, such as locking or catching in the knee, surgical intervention may be necessary to remove them.

3. Response to Conservative Treatments: The recommendation from the second physician to manage the condition with anti-inflammatory medications and follow-up appointments is a common approach for mild to moderate cases. If your mother does not experience relief from these treatments, or if her symptoms worsen, it may be an indication that surgery is needed.

4. Consultation with Specialists: It is advisable to seek a second opinion from an orthopedic surgeon who specializes in knee conditions. They can provide a thorough evaluation, including a physical examination and possibly advanced imaging (like MRI), to assess the extent of the damage and the best course of action.

5. Arthroscopic Surgery Benefits: Arthroscopic surgery is minimally invasive and can be effective in addressing issues such as removing loose bodies, smoothing out bone spurs, and repairing damaged cartilage. It typically involves a shorter recovery time compared to open surgery and can lead to significant improvements in pain and function.

In summary, whether your mother requires arthroscopic surgery for her knee bone spurs depends on the severity of her symptoms, the impact on her daily life, and her response to conservative treatments. If her quality of life is significantly affected, it may be worth considering surgical options. It is essential to have a detailed discussion with an orthopedic specialist who can provide personalized recommendations based on her specific condition.
In addition to surgical considerations, physical therapy may also be beneficial in strengthening the muscles around the knee, improving flexibility, and enhancing overall joint function. This conservative approach can sometimes alleviate symptoms and delay or even prevent the need for surgery.
Ultimately, the decision should be made collaboratively with healthcare providers, taking into account your mother's preferences, lifestyle, and overall health status.
