Why The Back Inside Portion Of Your Knee Might Hurt (Especially If You’re A Runner)
Lately I’ve had several conversations with athletes and runners about pain in the back inside portion of the knee.
Sometimes it feels tight.
Sometimes achy.
Sometimes sharp during certain movements.
And often, it starts to interfere with things people enjoy:
running
squatting
lunging
stairs
getting up and down from the floor
longer walks
sleeping comfortably
One of the most important things to understand is this:
Pain in that area can come from several different contributors.
The knee does not work alone.
The ankle, calf, hamstrings, hips, and even overall movement patterns all influence how stress moves through the joint.
In runners especially, I often see a combination of:
calf tightness or overuse
reduced ankle mobility
hip instability
tension through the posterior chain
repetitive loading without enough recovery
altered mechanics from fatigue
Sometimes the tissue surrounding the knee becomes overloaded simply because other areas are not sharing the work efficiently.
That does not automatically mean something is torn.
At the same time, it’s important not to ignore persistent symptoms either.
What We Often Focus On First
Rather than aggressively stretching or trying to “push through,” I usually encourage people to focus on improving support and movement quality around the knee.
Some helpful starting points include:
Gentle Calf Mobility
The calf muscles attach around the knee and can create a surprising amount of tension when they become overworked.
This may include:
gentle foam rolling
calf stretching with both a straight and bent knee
ankle mobility work
slow controlled calf raises
The goal is not to create pain.
The goal is to improve movement options.
Hip Stability & Control
The hips help control the position of the knee during walking, running, squatting, and landing.
Exercises may include:
monster walks
lateral band walks
glute bridges
supported single leg balance
hip airplanes
controlled step downs
Slower is often better here.
Control matters more than intensity.
Posterior Chain Movement
Tension through the hamstrings and backside of the body can also contribute to discomfort around the knee.
Helpful movements may include:
bridges
light hinge patterns
walking
dynamic warmups
gentle mobility work
Again, the goal is not aggressive stretching.
It’s helping the body move more efficiently.
Sometimes Reducing Load Is Part Of The Solution
Many active people struggle with this part.
But temporarily reducing irritation is not the same thing as “giving up.”
Sometimes the body simply needs:
less repetitive impact
fewer deep flexion positions
reduced sprinting or jumping volume
improved recovery
better sleep
more gradual progression
Backing off temporarily can create space for the tissue to calm down enough to tolerate movement better later.
When It’s Time To Get Evaluated
While many cases improve with thoughtful movement and load management, there are times where further assessment is important.
Consider seeing a doctor or physical therapist if you experience:
swelling
locking or catching
instability or giving way
inability to fully bend or straighten the knee
sharp pain with twisting
worsening symptoms over time
pain that consistently interrupts sleep
Pain does not always mean serious damage is present.
But persistent pain is information worth listening to.
The goal is not simply to “push through.”
The goal is to help the body feel strong, supported, and capable for the long term.
