Understanding Knee Instability: Common Causes

# Can an MRI Scan Clarify the Cause of Knee Instability?

## Why This Problem May Not Be Improving

Knee instability can be troubling and persistent. Clinically, several factors may contribute to this issue. Firstly, a structural injury not previously detected—such as an unnoticed tear in the meniscus or ligament—could be the cause. Additionally, there might be underlying disc or cartilage pathology, ligament or tendon injuries, or nerve compression that are not immediately obvious. Bone stress reactions may also play a role. It is crucial to consider that an incomplete or imprecise diagnosis from prior evaluations can lead to ongoing symptoms. After 6–12 weeks without improvement, further evaluation is advised to identify potential underlying causes more effectively.

## When Should an MRI Scan Be Considered?

An MRI scan may be considered if:
• Pain persists beyond 6–12 weeks
• Symptoms are worsening
