If your knee has started locking up, catching mid-stride, or giving way without warning, it’s natural to feel concerned.
These symptoms are more than just an inconvenience — they are often a sign that something structural inside the joint needs attention.
Below are six common causes of knee pain and how it can be treated.
These symptoms are more than just an inconvenience — they are often a sign that something structural inside the knee joint needs attention. Below are 6 Common Causes of Relentless Knee Pain.
What Do These Symptoms Actually Mean?
Locking is when your knee gets temporarily stuck in one position, usually bent, and you can’t fully straighten or bend it without manoeuvring it back into place.
Catching feels like a brief snag or hesitation during movement, often with a clicking or grinding sensation, as if something inside the joint is briefly getting trapped.
Buckling or giving way is when the knee suddenly feels unstable, as though it can’t bear weight, sometimes causing a stumble or fall.
Common Causes of Relentless Knee Pain
- Meniscal tears are one of the most frequent culprits. The meniscus is the cartilage cushion between your thigh and shin bones. A torn fragment can flip into the joint space and physically block movement, causing locking or catching.
- Loose bodies — small fragments of bone or cartilage that have broken away, often following injury or osteoarthritis — can float around the joint and jam it intermittently.
- Ligament injuries, particularly to the anterior cruciate ligament (ACL), often cause a feeling of instability or buckling, especially during twisting or pivoting movements.
- Patellar instability occurs when the kneecap doesn’t track smoothly in its groove, sometimes partially dislocating and causing a sudden give-way sensation.
- Osteoarthritis can cause catching and locking as the joint surfaces roughen and bony growths (osteophytes) develop, interfering with smooth movement.
- Patellofemoral pain syndrome can also contribute to a sense of weakness or buckling, particularly going up or down stairs.
Why You Shouldn’t Ignore Knee Pain
Repeated locking or buckling can cause further damage to the knee joint surfaces over time, and increases your risk of falls. Identifying the underlying cause early often means simpler, less invasive treatment.
Getting an Accurate Diagnosis
A thorough assessment typically involves a clinical examination to test stability, range of motion, and specific ligament and meniscus tests, followed by imaging. An x-ray will demonstrate the presence of osteoarthritis if present. An MRI scan also a useful tool, as it shows soft tissue structures like the meniscus and ligaments in detail that X-rays don’t capture. X-rays, however, remain useful for assessing joint space narrowing and bony changes associated with arthritis.
6 Treatment Options for Knee Pain
Physiotherapy is often the first step, particularly for instability related to muscle weakness or patellar tracking issues. A tailored strengthening and proprioception programme can significantly improve symptoms.
Activity modification and bracing can help manage symptoms while a longer-term plan is developed, particularly for milder cartilage issues or early arthritis.
Arthroscopic (keyhole) surgery is commonly used to trim or repair a torn meniscus, remove loose bodies or address certain cartilage damage. Recovery from a knee arthroscopy is generally quicker than open surgery, with many patients returning to light activity within a few weeks.
Ligament reconstruction, such as ACL reconstruction, may be recommended if instability is significant, particularly for those wanting to return to sport or physically demanding work.
Realignment procedures can address recurrent patellar instability by correcting how the kneecap tracks.
Knee joint replacement may be considered for advanced osteoarthritis. If the knee is locking, there is instability, accompanied by significant pain and reduced mobility, a total knee replacement may be recommended if conservative measures haven’t helped. A partial knee replacement is an alternative to total knee replacement for some people with osteoarthritis and is limited to a single compartment of the knee.

About Knee Surgery
Knee replacement surgery replaces the worn out, painful and stiff knee joint with a new prosthetic joint. This procedure which may be a partial or a total replacement is normally performed under spinal anaesthesia and is usually followed by a night or two in the hospital. Day-case knee replacement surgery may be an appropriate option for you.
