Bone marrow lesions (BMLs) are commonly identified on knee MRI and are increasingly recognized as an important contributor to knee pain, particularly in patients with osteoarthritis or prior joint injury. These lesions reflect changes within the bone beneath the joint surface and may be associated with pain, inflammation, and altered joint mechanics.
At our Miami clinic, we provide a comprehensive, non-surgical approach to the evaluation and treatment of bone marrow lesions focused on accurate diagnosis, symptom management, joint preservation, and individualized care planning.
Bone marrow lesions are areas within the bone that appear as signal changes on MRI, typically beneath the cartilage surface of the knee joint. They are sometimes referred to as bone marrow edema–like lesions, though they represent a variety of underlying bone changes rather than simple fluid accumulation.
Bone marrow lesions are most commonly seen in:
They are not visible on standard X-rays and are best identified using MRI.
Research has shown that bone marrow lesions are often associated with:
In many patients, bone marrow lesions correlate more closely with pain than cartilage loss alone. However, not all bone marrow lesions cause symptoms, which is why clinical correlation is essential.
Diagnosis involves correlating MRI findings with symptoms and physical examination. Evaluation typically includes:
Detailed history and symptom assessment
Physical examination focusing on knee mechanics and joint loading
Review of prior imaging
MRI of the knee to identify bone marrow lesions and associated joint changes
Imaging findings are interpreted in the context of symptoms, as not all lesions require intervention.
Neck pain may result from degenerative, mechanical, or traumatic conditions, including:
Modern work habits and prolonged screen use make neck pain increasingly common in both younger and older adults.
Symptoms may vary depending on lesion size, location, and underlying joint health. Common symptoms include:
Symptoms often overlap with those of knee osteoarthritis.
Treatment is individualized and focuses on reducing pain, improving function, and addressing contributing factors. If the bone marrow lesions is asymptomatic, it is unlikely that any treatment needs to be undertaken.
Physical therapy may focus on:
Activity modification is often an important part of treatment.
Appropriate medication strategies may include:
Medications can help manage symptoms while other therapies promote healing.
Targeted injections can reduce inflammation and pain:
These are performed under imaging guidance when appropriate to ensure accuracy and safety.
Knee braces, orthotics, and supportive devices may reduce strain and improve stability during activities.
In cases where conservative care alone is insufficient, regenerative medicine options may help support the body’s own healing processes and improve long-term outcomes.
Regenerative treatments may include:
These procedures use your own biologic materials to enhance healing and function, helping avoid or delay the need for surgery in many cases.
| Treatment Type | Purpose | Duration of Impact | Invasiveness |
|---|---|---|---|
| Physical Therapy | Improve movement and function | Long-term with adherence | Non-invasive |
| Medications | Pain and inflammation control | Short-term | Non-invasive |
| Bracing/Support | Reduce joint stress | Activity-dependent | Non-invasive |
| Injections (steroid, hyaluronic acid) | Reduce inflammation | Weeks to months | Minimally invasive |
| Regenerative Treatments (PRP/Cell) | Promote healing | Potential long-term | Minimally invasive |
| Surgery (if necessary) | Structural repair | Permanent | Invasive |
Many patients benefit from a coordinated, non-surgical plan before considering surgical intervention.
You may be a good candidate if you:
Treatment plans are individualized based on imaging findings, symptoms, and functional goals.
Active adults and professionals often place significant stress on the knees through sports and repetitive movements which can sometimes lead to the development of painful bone marrow lesions. Treatment focuses on:
The goal is to help patients remain active and productive while managing symptoms safely and effectively.
Rarely. Most cases of painful bone marrow lesions can be treated successfully with non-surgical care including therapy, patience, injections, and regenerative procedures.
When performed by trained specialists using your own biologic materials, regenerative procedures are generally considered safe and may support healing processes. These procedures should always be performed with imaging guidance like ultrasound and fluoroscopy to target very specific structures in or around the knee joint.
Recovery times vary by condition and treatment. Rehabilitation and regenerative care may take weeks to months for optimal improvement.
Imaging is used when it will meaningfully influence diagnosis or treatment planning. An MRI is the study that can detect a bone marrow lesion that may be associated with pain.
