Sudden knee pain while running can interrupt your workout and make walking uncomfortable. While muscle strain and tendon injuries are possible causes, an anterior cruciate ligament (ACL) injury may also be responsible, particularly if the pain starts after a sudden twist, awkward landing, or change in direction.
What Are the Symptoms of an ACL Injury?
The ACL is an important ligament that helps stabilize the knee joint. An injury may occur during running, football, cricket, or other activities involving sudden movements.
Common symptoms include:
- Sudden knee pain during physical activity
- A popping sensation at the time of injury
- Swelling that develops within a few hours
- Difficulty bending or straightening the knee
- A feeling that the knee is unstable or giving way
However, these symptoms do not always indicate an ACL tear. A proper orthopedic evaluation is necessary to identify the cause.
What Should You Do After Sudden Knee Pain?
If you experience sudden knee pain while running, stop the activity and avoid putting unnecessary stress on the affected knee. Applying a cold pack wrapped in a towel for short periods may help manage swelling.
Consult an orthopedic doctor if the pain persists, swelling develops, or your knee feels unstable. Depending on the examination findings, an MRI may be recommended to assess the ACL and other structures within the knee.
What Are the Treatment Options for an ACL Injury?
Treatment depends on the severity of the injury, knee stability, activity level, and associated damage. Some patients may benefit from physiotherapy, muscle strengthening, and activity modification. ACL reconstruction surgery may be considered for selected patients with significant instability or those who wish to return to sports involving pivoting movements.

Seek urgent medical attention if you cannot bear weight, have severe swelling, notice a deformity, or experience a locked knee.
Do not resume running or sports until your knee has been assessed and it is safe to return to physical activity.
