Quick Answer: What Causes Pain on the Inside of the Knee?
Pain on the inside of the knee can be caused by knee osteoarthritis, meniscus injury, MCL injury, pes anserine bursitis, muscle weakness or movement overload. Where the pain is located, how it started and which activities aggravate it can provide useful clues. A physiotherapist can assess your knee, hip and ankle movement, strength and functional activities to identify factors contributing to the pain and guide appropriate treatment.
What Does Inner Knee Pain Mean?
The inside of the knee, known medically as the medial side, contains several structures that can become a source of pain, the joint line itself, ligaments, tendons, and small fluid-filled sacs called bursae. Inner knee pain is common among people who spend long hours sitting cross-legged or squatting, both common postures in Indian households, offices, and kitchens, which place specific strain on this side of the joint.
The location of your pain does narrow down the possible causes, but the exact diagnosis depends on a movement-based assessment and clinical examination, not just where it hurts. Whether you describe it as inner knee pain, medial knee pain, or simply pain inside knee, physiotherapy focuses on identifying the actual source of the problem and restoring normal movement, rather than simply labelling the pain and moving on.
Where Exactly Is the Pain on the Inside of Your Knee?
Understanding precisely where and how your pain inside the knee presents is one of the most useful starting points for narrowing down the cause.
Pain Along the Joint Line
Pain felt right along the joint line, where the thigh bone meets the shin bone, is often associated with a meniscus injury or early osteoarthritis affecting the medial side of the joint. This type of pain often becomes more noticeable with twisting movements or deep bending, such as sitting cross-legged.
Pain Below the Knee Joint
Pain felt a little lower, just below the joint itself, is commonly seen with pes anserine bursitis or irritation of the tendons that attach in this area. This pain is often more localised and tender to touch than joint-line pain and can flare up with repetitive activities like climbing stairs.
Pain After Twisting the Knee
Medial knee pain that started suddenly after a twisting movement may indicate ligament or meniscus involvement, particularly if it was accompanied by swelling or a popping sensation at the time of injury. This kind of onset is worth mentioning specifically to your physiotherapist, since it changes the assessment approach.
Pain That Develops Gradually
Inner knee pain that develops slowly over weeks or months, without a specific injury, can be associated with repetitive activity, gradual joint changes or increasing load on the knee. Muscle weakness or altered movement patterns may also contribute to how the knee handles load during everyday activities.
| Pain Location | Possible Association |
|---|---|
| Along the joint line | Meniscus irritation, early osteoarthritis |
| Just below the joint | Pes anserine bursitis, tendon irritation |
| Sudden onset after twisting | Ligament or meniscus involvement |
| Gradual, no specific injury | Overload, muscle weakness, gradual joint changes |
Inner Knee Pain After Sitting Cross-Legged or Getting Up from the Floor
Sitting cross-legged or getting up from the floor may aggravate inner knee pain, particularly if deep knee bending or twisting increases pressure on sensitive tissues. If these movements cause discomfort, try using a higher chair temporarily, use stable support when standing up, and avoid forcing painful positions. Persistent pain may need a physiotherapy assessment to identify contributing factors.
Common Causes of Inner Knee Pain
Knee Osteoarthritis
Wear & tear of the joint cartilage on the medial side of the knee is a common cause of inner knee pain, particularly in people over 40.

Meniscus Injury
The medial meniscus, a cushioning structure within the knee, can become irritated or torn, causing pain along the inner joint line.
Medial Collateral Ligament (MCL) Injury
The MCL runs along the inner side of the knee and can be strained or injured, typically following a specific twisting or impact incident.
Pes Anserine Bursitis
This involves irritation of a small bursa located just below the inner knee joint, often causing a more localised, tender area of pain.

Why Does My Inner Knee Hurt at Night?
Inner knee pain at night can be associated with osteoarthritis, tendon or bursa irritation, overuse or an injury. Pain that persists, worsens, repeatedly disrupts sleep or occurs with significant swelling, redness, fever or difficulty bearing weight should be medically assessed. Night pain alone does not identify the cause, so the pattern of symptoms and clinical examination matter.
Movement Overload and Muscle Weakness
Movement overload and muscle weakness can contribute to ongoing inner knee pain and may be addressed through targeted rehabilitation.
Hip weakness can allow the knee to drift inward during activities like walking or climbing stairs, increasing strain specifically on the medial side of the joint.
Quadriceps weakness reduces the muscle’s ability to properly support and control the knee under load, particularly during activities that involve bending, like squatting or getting up from a low chair.
Poor lower limb alignment– how the hip, knee, and foot line up during movement- can concentrate extra force on the inner knee over time, sometimes without the person ever noticing the pattern developing.
Repetitive loading, such as frequent squatting, kneeling, or cross-legged sitting without adequate strength to support these positions, gradually adds up and contributes to ongoing irritation, which is a particularly common pattern given how often these positions come up in daily Indian life, from cooking and prayer to floor seating.
Addressing relevant movement and strength factors may help improve symptoms and reduce the risk of recurrence.
How Physiotherapists Find the Cause of Inner Knee Pain
The location of your pain is an important clue, but it does not always tell you what is causing it. At ReLiva, physiotherapists use a movement-based assessment to understand how your knee functions during the activities that trigger your symptoms.
Looking Beyond Where It Hurts
Your physiotherapist may assess how your knee behaves during walking, climbing stairs, squatting, sitting down and getting up from a chair. They also look at how the hip, knee and ankle work together, rather than examining the painful area in isolation.
Assessing Strength, Mobility and Movement Control
The assessment may include knee, hip and ankle mobility, quadriceps and hip strength, balance and control during functional movements. These findings can help identify movement or strength factors that may be contributing to your symptoms.
Identifying What May Be Contributing to Your Pain
Two people can have pain in exactly the same location but different contributing factors. One person may have reduced quadriceps strength, while another may have limited ankle mobility or altered movement control. At ReLiva, these assessment findings help physiotherapists identify the factors relevant to your symptoms and build a rehabilitation plan around them.
Physiotherapy Treatment for Inner Knee Pain
Managing Pain in the Early Stage
Initial treatment focuses on activity modification and appropriate pain relief approaches, aimed at calming the knee down without requiring complete inactivity. This might include temporarily reducing high-load activities like deep squatting while still keeping the knee gently moving.
Restoring Normal Movement
Improving mobility and flexibility around the knee, hip, and ankle helps restore movement that pain may have restricted, which is often an important foundation before strengthening begins in earnest.
Strengthening Muscles That Support the Knee
A structured programme targets the quadriceps, hip muscles, calf, and core, since weakness in any of these areas can contribute to ongoing strain on the inner knee. This strengthening work progresses gradually, based on how your knee responds at each stage. These exercises can be progressed according to your symptoms and functional goals. See our guide to knee pain exercises recommended by physiotherapists.
Improving Movement Patterns
Treatment addresses how you actually move during daily activities — walking, using stairs, sit-to-stand transitions, and squatting, correcting the specific patterns placing extra load on the medial knee, since many people unconsciously compensate around their pain in ways that make things worse over time.
Preventing Recurrence
Progressive loading and a tailored home exercise programme help ensure the improvement holds over the long term, rather than the pain returning once you resume normal activity, sport, or household tasks involving squatting and kneeling.
Inner Knee Pain Affecting Your Daily Activities?
If pain is making walking, climbing stairs, squatting or getting up from a chair difficult, a physiotherapy assessment can help identify the factors contributing to your symptoms and guide a personalised rehabilitation plan.
What Can You Do at Home for Inner Knee Pain?
These steps may help manage mild inner knee pain:
-
Modify painful activities: Temporarily reduce movements that aggravate your symptoms.
-
Avoid painful deep bending: Limit deep squats or prolonged cross-legged sitting if these increase pain.
-
Keep moving gently: Continue comfortable walking and knee movements as tolerated rather than resting completely.
-
Choose suitable exercises: Try knee pain exercises recommended by physiotherapists that match your symptoms and ability.
Seek professional assessment if pain persists, worsens or affects daily activities.
Can You Continue Walking or Exercising?
In most cases, yes, with some sensible adjustment rather than complete avoidance. Walking is usually fine to continue, often at a slightly reduced pace or distance during a flare-up. Stair use may need to be more careful, using a handrail where needed.
Cycling is often better tolerated than running, since it loads the knee more predictably and without impact. Running may need to be paused or reduced until strength and movement control improve, since the repetitive impact can aggravate an already irritated inner knee. Rather than generic advice, recovery generally follows a clear rehabilitation pathway: pain reduction, followed by restoring movement, improving strength, retraining everyday activities like walking, stairs, squatting, and getting up from a chair, and finally, preventing recurrence through ongoing conditioning.
When Should You See a Physiotherapist?
You should see a physiotherapist if you’re experiencing:
- Persistent pain that isn’t settling
- Swelling around the knee
- A feeling of instability or the knee giving way
- Difficulty walking normally
- Repeated flare-ups of inner knee pain
If any of these apply to you, a proper assessment can identify the real cause of your pain on inside of knee and guide the right treatment, rather than letting it linger or worsen over time.
Frequently Asked Questions
Why Does the Inside of My Knee Hurt?
Inner knee pain can come from several sources, including the meniscus, ligaments, bursa, or simply muscle weakness and movement overload. A proper assessment at ReLiva Physiotherapy and Rehab can pinpoint the exact cause.
Is Inner Knee Pain Always Arthritis?
No, while arthritis is one possible cause, inner knee pain is often related to bursitis, muscle weakness, or movement overload, particularly in younger or more active people. A physiotherapist at ReLiva Physiotherapy and Rehab can help determine which applies to you.
Can Physiotherapy Help Medial Knee Pain?
Yes. Physiotherapy can help manage medial knee pain by addressing contributing factors such as strength, mobility, movement control and activity tolerance. The appropriate treatment depends on the findings of your assessment.
Should I Stop Walking With Knee Pain?
Usually not. Most people can continue walking with some modification, though a physiotherapist at ReLiva Physiotherapy and Rehab can advise on the right level of activity for your specific case.
Can Weak Muscles Cause Inner Knee Pain?
Yes. Weakness in the quadriceps and hip muscles can affect how the lower limb controls and distributes load during movement. This may contribute to knee symptoms in some people, which is why strength and movement control are considered during a physiotherapy assessment, as suggested by studies.
