5 Reasons Why Your Knee Is Hurting: Common Causes of Knee Pain
- 13 minutes ago

Knee pain can make everyday activities like walking, climbing stairs, exercising, or even getting out of a chair uncomfortable. While knee pain is sometimes caused by an obvious injury, it can also develop gradually without a clear reason.
The knee is a complex joint involving bones, cartilage, ligaments, tendons, muscles, and other soft tissues. Pain can develop when any of these structures become irritated, overloaded, injured, or are not working efficiently.
At Uniphysio & Associates, physiotherapy for knee pain focuses not only on where you feel the pain, but also on identifying the factors that may be contributing to it.
Here are 5 common reasons why your knee may be hurting and how physiotherapy may help.
1. Knee Pain From Muscle Weakness or Imbalance
Your knee relies heavily on the muscles surrounding your hips, thighs, and lower legs for support and control.
Weakness or imbalance in the quadriceps, hamstrings, gluteal muscles, or calf muscles can change how forces travel through the knee during movement.
You may notice:
Pain when climbing or descending stairs
Discomfort when squatting
Knee pain after walking or exercising
Difficulty getting up from a chair
A feeling that the knee is weak or unstable
A physiotherapist can assess your strength and movement patterns and develop an individualized exercise program to improve support around the knee.
2. Patellofemoral Pain: Pain Around the Kneecap
One common source of knee pain is patellofemoral pain, which typically causes discomfort around or behind the kneecap.
Symptoms can become more noticeable during activities that increase pressure between the kneecap and the thigh bone, such as:
Running
Squatting
Using stairs
Kneeling
Sitting with the knees bent for a long time
Hip and leg strength, training load, biomechanics, and movement patterns may all contribute.
How Physiotherapy Can Help Patellofemoral Knee Pain
Treatment may include strengthening, mobility exercises, activity modification, movement retraining, and hands-on techniques depending on your individual assessment.
3. Knee Pain From Tendon Overload
Tendons connect muscles to bones. Repetitive loading or a sudden increase in physical activity can sometimes irritate the tendons surrounding the knee.
For example, patellar tendinopathy can cause pain at the front of the knee, often just below the kneecap.
This may occur in people who participate in activities involving frequent:
Running
Jumping
Squatting
Sports
High-intensity training
One important part of treatment is determining how much load the tendon can currently tolerate. Completely avoiding activity is not always the answer. A progressive strengthening and loading program can often be an important component of rehabilitation.
4. Osteoarthritis Can Cause Knee Pain
Knee osteoarthritis becomes more common with age, but finding arthritis on an X-ray does not necessarily tell us exactly how much pain or limitation someone will experience.
Common symptoms may include:
Knee stiffness
Aching
Reduced range of motion
Pain after prolonged activity
Difficulty with stairs
Stiffness after sitting or resting
Can Physiotherapy Help Knee Pain From Osteoarthritis?
Physiotherapy can play an important role in managing knee osteoarthritis. Treatment may focus on improving strength, mobility, joint function, physical activity tolerance, and confidence with movement.
The goal is not simply to “treat the X-ray.” It is to help you move and function better.
5. Your Knee Pain May Be Related to How You Move
Sometimes the painful knee is only part of the picture.
Your hip, ankle, foot, and overall movement mechanics can influence the amount and direction of force placed through the knee.
For example, limited ankle mobility, reduced hip strength, or poor control of the leg during walking, running, or squatting may increase stress on certain structures around the knee.
That is why a physiotherapy assessment should look beyond the painful area.
A physiotherapist may assess:
Knee mobility
Hip and ankle mobility
Muscle strength
Balance
Walking or running mechanics
Squatting and functional movements
Your exercise and activity levels
Understanding why your knee is hurting can help guide a more individualized treatment plan.
When Should You See a Physiotherapist for Knee Pain?
Consider having your knee assessed if your knee pain is persistent, keeps returning, limits your daily activities, or prevents you from participating in exercise or sports.
You should seek more urgent medical attention if knee pain follows a significant injury or is accompanied by severe swelling, inability to bear weight, significant deformity, a hot/red joint with fever, or other concerning symptoms.
