Quadriceps Strain
A strain or minor muscle injury affecting the quadriceps muscles at the front of the thigh. It commonly occurs during sprinting, acceleration, jumping, powerful kicking, or rapid changes of direction.
- •Mild pain or tenderness at the front of the thigh
- •Pain is mainly noticeable during sprinting, acceleration, or powerful movements
- •Mild discomfort when bending the knee or extending the leg against resistance
- •No or very little swelling
- •Normal or almost normal walking
- •Stop activity that causes pain
- •Avoid sprinting, jumping, and powerful kicking during the first few days
- •Use relative rest with pain-free movement
- •Cold therapy may be used briefly if comfortable
- •Begin gentle pain-free movement as soon as tolerated
Pain-free movement of the hip and knee
Gentle quadriceps exercises with low resistance
Progressive strengthening of the quadriceps
Progress from isometric exercises to dynamic loading
Light jogging once walking and strengthening exercises are pain-free
Gradually progress to faster running and acceleration
- Pain-free walking and daily activities
- Full range of motion in the hip and knee
- No significant tenderness in the quadriceps
- Pain-free strengthening exercises
- Able to jog and run without pain
- Able to accelerate and decelerate without pain
- Able to perform football-specific drills without symptoms

Quadriceps Strain
A strain or minor muscle injury affecting the quadriceps muscles at the front of the thigh. It commonly occurs during sprinting, acceleration, jumping, powerful kicking, or rapid changes of direction.
Mild — 1–3 veckor
Symptoms
- Mild pain or tenderness at the front of the thigh
- Pain is mainly noticeable during sprinting, acceleration, or powerful movements
- Mild discomfort when bending the knee or extending the leg against resistance
- No or very little swelling
- Normal or almost normal walking
Acute Treatment
- Stop activity that causes pain
- Avoid sprinting, jumping, and powerful kicking during the first few days
- Use relative rest with pain-free movement
- Cold therapy may be used briefly if comfortable
- Begin gentle pain-free movement as soon as tolerated
Rehabilitation
Pain-free movement of the hip and knee
Gentle quadriceps exercises with low resistance
Progressive strengthening of the quadriceps
Progress from isometric exercises to dynamic loading
Light jogging once walking and strengthening exercises are pain-free
Gradually progress to faster running and acceleration
Return to Play
- ☐ Pain-free walking and daily activities
- ☐ Full range of motion in the hip and knee
- ☐ No significant tenderness in the quadriceps
- ☐ Pain-free strengthening exercises
- ☐ Able to jog and run without pain
- ☐ Able to accelerate and decelerate without pain
- ☐ Able to perform football-specific drills without symptoms
Moderate — 3–6 veckor
Symptoms
- Clear pain at the front of the thigh
- Pain may occur suddenly during sprinting, kicking, or jumping
- Tenderness over the injured area
- Pain with knee flexion or active knee extension
- Reduced quadriceps strength
- Swelling or bruising may develop
- Running and kicking are difficult or painful
Acute Treatment
- Stop the sporting activity immediately
- Avoid sprinting, jumping, kicking, and other activities that provoke pain
- Use relative rest and pain-free movement
- Cold therapy may be used briefly for symptom relief
- Assessment by a physiotherapist is recommended with significant pain, strength loss, or persistent symptoms
Rehabilitation
Pain-free movement of the hip and knee
Begin isometric quadriceps loading when tolerated
Progressive strengthening with increasing resistance
Train both slower and faster muscle contractions
Progress to running when strength and movement allow
Progress to acceleration, deceleration, and changes of direction
Finish with football-specific activities such as kicking and high-intensity running
Return to Play
- ☐ Pain-free daily activities and full range of motion
- ☐ No or minimal tenderness over the injury
- ☐ Near-normal strength compared with the uninjured leg
- ☐ Able to perform repeated knee extensions and strengthening exercises without pain
- ☐ Able to run at high speed without symptoms
- ☐ Able to accelerate, decelerate, and change direction without pain
- ☐ Able to kick and perform football-specific activities at full intensity
- ☐ Able to complete full 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 or rapidly developing bruising
- Pain with very small movements or loading
- In some cases, a visible depression or change in the muscle contour may occur
Acute Treatment
- Stop the activity immediately
- Avoid unnecessary weight-bearing on the leg
- Avoid massage and aggressive stretching during the acute stage
- Cold therapy may be used briefly for symptom relief
- Medical assessment is recommended promptly when a significant muscle tear is suspected
- Further examination may be needed to determine the extent of a major injury
Rehabilitation
Begin rehabilitation with pain-free movement and gradual loading
Progressive activation of the quadriceps
Progressive strengthening with increasing resistance
Gradual training of the muscle's ability to produce force rapidly
Gradual return to jogging followed by faster running
Introduce acceleration, deceleration, and changes of direction progressively
Football-specific training including kicking and high-intensity running
Return to full training only when strength, function, and load tolerance 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 strength compared with the uninjured leg
- ☐ Pain-free high-load strengthening
- ☐ Able to run at high speed without pain or apprehension
- ☐ Able to repeatedly accelerate and decelerate
- ☐ Able to perform jumps and explosive movements without symptoms
- ☐ Able to kick with full power without pain
- ☐ Able to complete full-intensity football training without symptoms
- ☐ No deterioration or increased pain after training
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 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
