Understanding Knee Locking: Causes and Symptoms

# Knee Locking Even After Physiotherapy — Do I Need an MRI Scan?

## Why This Problem May Not Be Improving
Persistent knee locking may occur for several clinically relevant reasons, even after undergoing physiotherapy. Possible causes include undetected structural injuries, disc or cartilage pathology, ligament or tendon injuries, nerve compression, bone stress reactions, incomplete or imprecise diagnoses, or a plateau in recovery after conservative treatment. If symptoms persist for more than 6 to 12 weeks, a reevaluation may be warranted.

## 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 in the knee
• Night pain is present
• 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

It is important to note that an MRI is not always necessary in every case.

## MRI Scan Safety
MRI scans are considered safe for most patients and differ from X-rays or CT scans in that they do not use ionising radiation. Instead, an MRI scan utilizes magnetic fields and radiofrequency signals to create images, making it a preferred option for detailed soft tissue assessment. Safety screenings are conducted prior to imaging for all patients.

## Transparent MRI Scan Pricing (As of 1 March 2026)
Most musculoskeletal (MSK) MRI scans are typically priced between SGD $950 to $1,000, depending on the body region being scanned. It is advisable to confirm pricing details during consultation.

What To Expect When I Visit The Pain Relief Clinic

A typical visit will involve our doctor first understanding your medical history, concerns and previous experience with other pain treatments.

For patients who have consulted many people but have yet to receive a clear diagnosis, selecting an affordable imaging scan might be recommended to confirm the cause of your pain..

Some patients have already done scans with other doctors for their pain condition but are still not clearly told what they suffer from.

Dr Terence Tan is happy to offer you a second opinion and recommend how best to manage your condition.

We also see patients who already have a confirmed diagnosis from specialist pain doctors, but are "stuck” because treatment options offered are not practical or acceptable.

We can help by discussing options that you might have potentially never been told of.

A common experience is when a patient has already consulted a specialist doctor for pain management and is told to consider orthopaedic surgery which they find too aggressive.

Or they may have seen doctors for their pain and were prescribed painkillers with potential side effects which made them feel uncomfortable.

Many of our patients have also first tried complementary treatments or acupuncture with traditional Chinese pain doctors.

They look for a second opinion after finding any relief experienced from other treatments to be temporary or requiring repetitive treatments, which add up to time and cost.

Especially in such situations, we emphasize using non-invasive medical technology you likely have not been told about .

This can make a big difference to your results.
