Understanding Knee Instability: Causes and Symptoms

# Knee Pain That Feels Unstable Despite Rehab — Do I Need an MRI Scan?

## Why This Problem May Not Be Improving
Persistent knee pain accompanied by a feeling of instability may stem from several clinically relevant factors. These could include a structural injury that has not been previously detected, such as ligament or tendon injuries, or disc and cartilage pathologies. Additionally, nerve compression or bone stress reactions might also contribute to the sensations of instability. An incomplete or imprecise diagnosis can lead to ongoing issues, and it’s possible for symptoms to plateau after conservative treatment. If your symptoms persist beyond 6–12 weeks, it may be advisable to seek further evaluation.

## When Should an MRI Scan Be Considered?
An MRI scan may be considered if:
• Pain persists beyond 6–12 weeks
• Symptoms are worsening
• There is numbness, tingling, or weakness
• There is night pain
• There is recurrent swelling
• X-rays are normal but symptoms continue
• Conservative treatment has plateaued
• Diagnosis remains unclear
• Surgery is being considered

An MRI scan provides detailed evaluation of:
• Discs
• Ligaments
• Tendons
• Cartilage
• Meniscus
• Labrum
• Nerve roots
• Bone marrow changes
While an MRI scan offers valuable information, it is important to understand that it may not always be necessary for every case.

## MRI Scan Safety
MRI scans are considered safe for most patients and differ from X-rays or CT scans as they do not use ionising radiation. Instead, an MRI scan employs magnetic fields and radiofrequency signals, making it a widely used method for detailed soft tissue assessment. All patients undergo a safety screening prior to imaging to ensure their well-being.
