Plica syndrome in the knee

You walk up a flight of stairs and suddenly feel a click in your knee. Sometimes it hurts, sometimes it doesn’t. When cycling, it feels like something is “rubbing” inside. You might even feel like your knee occasionally locks up.
Many people immediately think of a meniscus problem, but did you know it could be something else? It might be related to a plica, a small, often forgotten piece of tissue in your knee that can sometimes be quite troublesome.

In this blog, you’ll learn what Plica Syndrome is, how to recognize it, and most importantly, what you can do about it. You’ll also discover how the MotiMove app helps you with safe exercises to get your knee moving smoothly again.

What is a plica in the knee?

Inside your knee is a thin membrane: the joint capsule. Some people have a small fold in it: the plica.
Normally, you won’t notice it. But if the membrane becomes irritated, that plica can thicken and rub against other structures in the knee. That causes pain, clicking, or a “locking” sensation.

How does Plica Syndrome develop?

A plica can become irritated by:

  • Overuse (lots of stair climbing, running, cycling)
  • Repeated movements involving deep knee bending
  • Old injuries that make the capsule more sensitive
  • A fall or a blow to the knee

It’s often a combination of factors, where rest and targeted exercises promote recovery.

Symptoms you can recognize

People with Plica Syndrome often experience:

  • A click, crack, or rubbing sensation in the knee when bending and straightening
  • Stabbing pain on the inside or top of the knee
  • Sometimes swelling or a warm feeling
  • Difficulty sitting for long periods or climbing stairs
  • A feeling that the knee is “locking” now and then

Why it’s often missed

Because the plica is small and not always visible on an X-ray, Plica Syndrome is sometimes overlooked.
It can resemble a meniscus injury, which means people sometimes go months without the right treatment.
A physiotherapist or sports physician can often determine if it’s a plica with specific tests.

What can you do yourself?

Good news: Plica Syndrome often heals without surgery.
 What helps:

  • Avoid deep knee bends and activities that cause pain
  • Ice the knee if there’s swelling
  • Incorporate gentle stretching and mobility exercises
  • Strengthen the thigh muscles to offload the knee

With the right guidance, you often recover within a few weeks to months.
