Do you feel a sharp or aching pain on the outside of your knee when bending it? If so, you’re not alone. Lateral knee pain when bending is a common complaint, especially among athletes, active individuals, and those recovering from knee injuries. At Great Lakes Orthopaedics, we’re here to help you understand what might be causing your pain and how to treat it effectively.
What Is Lateral Knee Pain?
Lateral knee pain refers to discomfort on the outside of the knee joint. This pain may become more noticeable during activities that involve bending, such as:
- Walking or running
- Squatting
- Climbing stairs
- Sitting and standing
If you’re experiencing lateral knee pain when bending, it could be caused by one of several conditions.
Common Causes of Lateral Knee Pain When Bending
Common Causes of Lateral Knee Pain When Bending- Iliotibial Band Syndrome (ITBS)
This overuse injury occurs when the IT band, a thick band of tissue along the outside of the thigh, becomes tight or inflamed. It often affects runners and cyclists and can cause sharp pain on the outer knee when bending or extending the leg.
- Lateral Meniscus Tear
The meniscus is a cartilage structure that cushions your knee. A tear in the lateral meniscus can result in pain, swelling, and a catching or locking feeling—especially when bending or twisting the knee.
- Lateral Collateral Ligament (LCL) Injury
The LCL stabilizes the outer part of the knee. A sprain or tear to this ligament, often from a blow to the inner knee, can lead to lateral pain, instability, and difficulty bending the knee.
- Knee Osteoarthritis
Degenerative changes in the knee joint can cause lateral knee pain, particularly during movement. Bending may worsen the discomfort due to worn cartilage and inflammation.
- Bursitis
Inflammation of the bursa, a fluid-filled sac near the knee joint, can cause pain when bending. Lateral knee bursitis may occur due to repeated pressure or overuse.
