Knee Pain When Squatting: Common Causes and How To Fix It
Knee pain when squatting is one of the most common problems affecting active adults, gym-goers and people returning to exercise. It may appear during a loaded squat, when getting up from a chair, or while using stairs.
If knee pain is interfering with your training or everyday movement, our Knee Pain Physio in Varsity Lakes page explains how we assess knee symptoms and develop an individual rehabilitation plan.
The good news is that knee pain during squatting does not automatically mean that the joint is damaged. It often develops when the load being placed on the knee exceeds what it can currently tolerate.
Understanding where the pain is located, what aggravates it and how the knee responds after activity can help determine the most appropriate next step.
Why Does Knee Pain Happen When You Squat?
Squatting places load through:
The patellofemoral joint (kneecap)
The quadriceps tendon
The patellar tendon
The surrounding muscles and connective tissue
Pain commonly develops when:
Training volume increases too quickly
Load is increased faster than tissue adapts
There has been a recent break from training
There is underlying tendon irritation
Strength deficits exist through hips or quadriceps
Importantly, research consistently shows that tendons, cartilage and muscle adapt to progressive load over time. Problems arise when load exceeds current capacity, not simply because you are squatting.
This is why stopping squats completely often provides temporary relief but does not solve the underlying issue.
Where Is Your Knee Pain During Squats?
The location of pain can provide useful clues, although it cannot confirm a diagnosis by itself.
Pain around or behind the kneecap is commonly associated with patellofemoral pain and may be aggravated by squatting, stairs or prolonged sitting.
Pain below the kneecap may involve irritation of the patellar tendon, particularly when training includes repeated jumping, running or heavy lower-body work.
Pain above the kneecap may relate to the quadriceps tendon or surrounding tissues, especially after a sudden increase in squat volume or intensity.
Pain on the inside or outside of the knee can have several possible causes and should be considered alongside swelling, movement restrictions, recent trauma and other symptoms.
Because different presentations require different approaches, assessment should consider your symptoms, training history, strength and response to load rather than relying on pain location alone.
Why Knee Pain Keeps Coming Back
Many people rest until their symptoms reduce, then return to the same activity at the same intensity.
This creates a cycle:
Pain develops
Activity stops
Pain settles
Activity resumes at previous load
Pain returns
Without rebuilding strength and load tolerance, the knee remains vulnerable.
Common reasons knee pain persists:
Avoiding loading entirely
Only focusing on stretching
Relying on passive treatments
Not progressing exercises gradually
Returning to full training too quickly
Pain reduction is not the same as rehabilitation.
True rehabilitation improves tissue capacity so the knee can tolerate the demands placed on it.
If symptoms have persisted for several months or the knee has become increasingly sensitive to normal movement, a Chronic Pain Physiotherapy approach may also help rebuild confidence and tolerance gradually.
How Exercise-Based Rehabilitation Helps
At Next Level Physiotherapy and Strength Studio, knee rehabilitation is centred around progressive Exercise-Based Rehabilitation rather than rest or passive treatment alone.
This means:
Identifying aggravating loads
Modifying (not eliminating) movements
Gradually reintroducing load
Progressively strengthening relevant tissues
Building confidence under load
Rather than avoiding squats entirely, we often:
Adjust squat depth
Modify stance
Reduce load temporarily
Use alternative movements
Implement structured strength progressions
Research supports progressive loading as one of the most effective ways to manage patellofemoral pain and tendon-related knee pain.
When load is managed appropriately, most knees respond well.
This approach also supports long-term injury prevention, as strength and load tolerance are improved beyond baseline.
Should You Stop Squatting If Your Knee Hurts?
Not necessarily.
Many people can continue squatting with temporary modifications, provided symptoms remain manageable and do not progressively worsen.
Depending on your presentation, useful modifications may include:
Reducing the weight
Adjusting squat depth
Decreasing the number of sets or weekly sessions
Slowing the movement tempo
Trying a different squat variation
The goal is not to force a painful movement or avoid squatting indefinitely. It is to find a level of loading that the knee can currently tolerate and progress from there.
Seek an assessment if pain is sharp, worsening, associated with significant swelling or instability, or preventing normal daily activity.
What You Can Try Now
If you are experiencing knee pain when squatting, you can initially try:
Reducing the load rather than stopping completely
Temporarily adjusting squat depth
Avoiding sudden increases in training volume
Allowing more recovery between lower-body sessions
Monitoring how the knee responds later that day and the following morning
Mild discomfort does not always mean an exercise is harmful, but symptoms should remain manageable and should not continue escalating after every session.
If you cannot find a tolerable starting point, or the pain continues despite these changes, an assessment can provide more specific guidance.
When to See a Physiotherapist
You should consider physiotherapy if:
Pain has persisted longer than 1–2 weeks
Swelling is present
Pain is increasing despite modifying training
You are unsure how to progress safely
You have stopped exercising due to fear of making it worse
The knee locks, gives way or feels unstable
Pain followed a fall, twist or other significant injury
A physiotherapy assessment helps determine:
The likely source of symptoms
Current load tolerance
Contributing strength deficits
A clear progression plan
Our focus is not just settling pain, but helping you return to training and return-to-sport confidently and reduce the risk of recurrence.

Knee Pain When Squatting FAQs
-
Squatting places more load through the knee and requires greater strength and movement control than level walking. A knee may tolerate everyday walking but become uncomfortable when squat depth, resistance or training volume exceeds its current capacity.
-
Knee pain during squats is common, but it should not simply be ignored. Mild and short-lived discomfort may respond to load modification, while worsening, persistent or limiting pain should be assessed.
-
Complete rest is not always required. Many people can continue with a lighter load, reduced depth or different squat variation while rebuilding strength. The appropriate modification depends on how the knee responds during and after exercise.
-
The bottom of a squat places greater demand on the knee joint, quadriceps and surrounding tendons. Pain at this point may reflect reduced tolerance to deeper knee flexion, excessive load, tendon irritation or other contributing factors.
-
Hip and glute strength can influence lower-limb control, but knee pain is rarely caused by one weak muscle alone. Training load, quadriceps strength, movement tolerance, previous injury and recovery should also be considered.
Ready to Squat With Confidence Again?
If knee pain is limiting your training, exercise or everyday movement, a 60-minute physiotherapy assessment can help identify the likely contributors and provide a clear rehabilitation plan.
Our goal is not simply to settle your symptoms. It is to rebuild the strength, tolerance and confidence you need to return to squatting and the activities you enjoy.
