• Effective rehabilitation is crucial for managing knee injuries, but persistent symptoms may suggest the need for further evaluation.
• An MRI scan is an important diagnostic tool when knee pain and swelling do not improve with conservative treatment.
• There are alternative diagnostic approaches to consider before opting for an MRI, such as physical exams and X-rays.
• Consulting with a healthcare professional is key to determining the best course of action for persistent knee pain and swelling.

Understanding Knee Pain and Swelling After Activity

# Knee Pain With Swelling After Activity Despite Rehab — Do I Need an MRI Scan?

## Why This Problem May Not Be Improving

There can be several clinically relevant reasons why knee pain and swelling may persist despite rehabilitation efforts. Possible explanations include:
• Structural injuries not previously detected
• Disc or cartilage pathology affecting joint function
• Ligament or tendon injuries contributing to instability
• Nerve compression leading to pain and dysfunction
• Bone stress reactions from repetitive activity
• Incomplete or imprecise diagnosis resulting in ineffective treatment
• A plateau in recovery after conservative treatment approaches

If symptoms continue for more than 6 to 12 weeks, further evaluation may be recommended to get to the root of the issue.

## When Should an MRI Scan Be Considered?

An MRI scan may be considered if:
• Pain persists beyond 6–12 weeks
• Symptoms are worsening in severity
• You experience numbness, tingling, or weakness
• There is night pain that disrupts sleep
• Recurrent swelling occurs after activity
• Initial X-rays show no abnormalities but symptoms persist
• Conservative treatment has plateaued without improvement
• Diagnosis remains unclear despite ongoing assessment
• If surgery is being contemplated

An MRI scan provides detailed evaluation of:
• Discs
• Ligaments
• Tendons
• Cartilage
• Meniscus
• Labrum
• Nerve roots
• Bone marrow changes

It is important to note that an MRI is not always necessary for knee pain management.

## MRI Scan Safety

MRI scans are considered safe for most individuals. Unlike X-rays or CT scans, an MRI scan:
• Does not use ionising radiation
