Quadriceps Muscle Tear
A partial or more extensive tear of the quadriceps muscles at the front of the thigh. It commonly occurs during explosive movements such as sprinting, acceleration, jumping, powerful kicking, or rapid changes of direction.
- •Sudden pain or a sharp sensation at the front of the thigh
- •Localized tenderness over the injured area
- •Pain with forceful knee extension
- •Mild reduction in quadriceps strength
- •Mild discomfort during sprinting, jumping, or kicking
- •No or only minor swelling or bruising
- •Walking is usually possible but may cause some discomfort
- •Stop the activity that causes pain
- •Avoid sprinting, jumping, kicking, and explosive movements
- •Reduce load while maintaining pain-free movement
- •Cold therapy may be used briefly if comfortable
- •Avoid aggressive quadriceps stretching during the acute stage
- •Gradually reintroduce loading as pain decreases
Pain-free movement of the hip and knee
Gentle isometric quadriceps exercises
Gradual progression of strengthening load
Progress from slow strengthening exercises to faster and more explosive movements
Light jogging once walking and strengthening are pain-free
Gradual progression to acceleration and higher running speeds
Football-specific activities are introduced progressively
- Pain-free walking and daily activities
- Full range of motion in the hip and knee
- No significant tenderness over the injury
- Pain-free quadriceps strengthening
- Able to jog and run without pain
- Able to accelerate and decelerate without symptoms
- Able to jump and land without pain
- Able to kick and perform football-specific activities without symptoms

- Localized tenderness over the injured area
- Pain with forceful knee extension
- Mild reduction in quadriceps strength
- Mild discomfort during sprinting, jumping, or kicking
- No or only minor swelling or bruising
- Walking is usually possible but may cause some discomfort
Acute Treatment
- Stop the activity that causes pain
- Avoid sprinting, jumping, kicking, and explosive movements
- Reduce load while maintaining pain-free movement
- Cold therapy may be used briefly if comfortable
- Avoid aggressive quadriceps stretching during the acute stage
- Gradually reintroduce loading as pain decreases
Rehabilitation
Pain-free movement of the hip and knee
Gentle isometric quadriceps exercises
Gradual progression of strengthening load
Progress from slow strengthening exercises to faster and more explosive movements
Light jogging once walking and strengthening are pain-free
Gradual progression to acceleration and higher running speeds
Football-specific activities are introduced progressively
Return to Play
- ☐ Pain-free walking and daily activities
- ☐ Full range of motion in the hip and knee
- ☐ No significant tenderness over the injury
- ☐ Pain-free quadriceps strengthening
- ☐ Able to jog and run without pain
- ☐ Able to accelerate and decelerate without symptoms
- ☐ Able to jump and land without pain
- ☐ Able to kick and perform football-specific activities without symptoms
Moderate — 4–8 veckor
Symptoms
- Clear and often sudden pain at the front of the thigh
- May feel like a sharp pain or a sensation of the muscle tearing
- Significant tenderness over the injured area
- Reduced quadriceps strength
- Pain with active knee extension
- Pain during running, jumping, and kicking
- Swelling and bruising may develop
- Walking and using stairs may be painful
Acute Treatment
- Stop the sporting activity immediately
- Reduce load and avoid activities that increase pain
- Use pain-free movement within tolerance
- Cold therapy may be used briefly for symptom relief
- Avoid massage and aggressive stretching early after the injury
- Medical or physiotherapy assessment is recommended with significant weakness or suspected larger tear
Rehabilitation
Pain-free movement and gradual loading
Early isometric quadriceps training
Progressive strengthening with increasing resistance
Progress to exercises through a greater range of motion
Train both slow and rapid force production
Gradual return to jogging followed by faster running
Progress to acceleration, deceleration, and changes of direction
Football-specific training with gradually increasing intensity
Kicking and other powerful ball activities are reintroduced progressively
Return to Play
- ☐ Pain-free daily activities and full range of motion
- ☐ No or minimal tenderness over the injury
- ☐ Adequate quadriceps strength compared with the uninjured leg
- ☐ Able to perform high-load strengthening without pain
- ☐ Able to run at high speed without symptoms
- ☐ Able to repeatedly accelerate and decelerate
- ☐ Able to jump and land without pain or apprehension
- ☐ Able to perform rapid changes of direction
- ☐ Able to kick with high force without pain
- ☐ Able to complete full football training without increased symptoms afterwards
Severe — 8–12+ veckor
Symptoms
- Sudden and severe pain at the front of the thigh
- A clear sensation of the muscle tearing or giving way
- Marked loss of quadriceps strength
- Difficulty walking or bearing weight
- Significant swelling and often extensive bruising
- Pain with active knee extension
- Clear loss of function
- In some cases, a depression or change in the muscle contour may be visible or palpable
Acute Treatment
- Stop the activity immediately
- Minimize weight-bearing as necessary
- Avoid massage and aggressive stretching during the acute stage
- Cold therapy may be used briefly for symptom relief
- Seek medical assessment promptly when a major muscle tear is suspected
- Imaging may be required to assess the extent of a significant tear
Rehabilitation
Begin rehabilitation with pain-free movement and cautious loading
Gradual activation of the quadriceps
Progressive strengthening with gradually increasing resistance
Gradually restore the muscle's ability to tolerate high loads and rapid force production
Gradual return to jogging followed by faster running
Stepwise introduction of acceleration, deceleration, and changes of direction
Progress to jumping and other explosive movements
Football-specific training with gradually increasing intensity
Kicking and other powerful activities are introduced once the muscle tolerates high loads
Return to full training only when strength and function have recovered
Return to Play
- ☐ Pain-free daily activities and full hip and knee range of motion
- ☐ No significant residual tenderness
- ☐ Full or near-full quadriceps strength compared with the uninjured leg
- ☐ Able to perform heavy strengthening without pain
- ☐ Able to run at the highest relevant speed without symptoms
- ☐ Able to repeatedly accelerate and decelerate
- ☐ Able to jump, land, and perform explosive movements without pain
- ☐ Able to perform rapid changes of direction
- ☐ Able to kick with full power without pain
- ☐ Able to complete full-intensity football-specific training
- ☐ Able to complete full training without deterioration or increased symptoms afterwards
When to Seek Medical Care
- Seek medical care after sudden severe pain or a clear sensation that the muscle has torn
- Seek medical care if walking or bearing weight is difficult
- Seek medical care with significant swelling, extensive bruising, or marked loss of strength
- Seek medical care if you can see or feel a clear depression or change in the muscle's shape
- Seek medical care if knee extension is significantly impaired
- Seek medical care if symptoms do not clearly improve despite rest and gradual rehabilitation
- In children and adolescents, significant or sudden thigh pain should be assessed carefully because injuries to growth areas can also occur
