Understanding Knee Instability After an Injury

# My Knee Feels Unstable After Twisting Injury — Do I Need an MRI Scan?

## Why This Problem May Not Be Improving
Persistent knee instability following a twisting injury may be due to several clinically relevant factors:
• Structural injury not previously detected: Damage to ligaments or cartilage may not be obvious in initial evaluations.
• Disc or cartilage pathology: Injuries may involve tears or degeneration that aren’t easily identified.
• Ligament or tendon injury: Common in twisting injuries, these can lead to instability.
• Nerve compression: This can cause weakness or instability if nerves are affected.
• Bone stress reactions: Repetitive injury may stress the bone, leading to instability.
• Incomplete or imprecise diagnosis: Sometimes initial assessments do not capture the full extent of the injury.
• Plateau after conservative treatment: If symptoms persist despite treatment efforts, further evaluation may be warranted.

It is important to note that if symptoms persist beyond 6–12 weeks, further evaluation should be considered.

## 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 a detailed evaluation of structures such as discs, ligaments, tendons, cartilage, meniscus, labrum, nerve roots, and bone marrow changes. However, an MRI is not always necessary.

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