If your knee ever feels like it might give out when walking, running, or standing, you could be experiencing knee instability. This common condition can result from injury, overuse, or degenerative changes in the joint—and it often signals an underlying issue that should be addressed by an orthopedic specialist.
Understanding Knee Instability
Knee instability occurs when the structures that support and stabilize the knee—such as ligaments, tendons, cartilage, and muscles—are weakened or damaged. As a result, the knee may feel wobbly, unreliable, or even buckle during movement.
At Plano Orthopedic & Sports Medicine Center, we regularly diagnose and treat patients dealing with knee instability due to a variety of causes. Whether it’s the result of a sports injury or long-term wear and tear, understanding the symptoms and causes is the first step toward recovery.
Common Causes of Knee Instability
-
Ligament Injuries: Damage to the ACL (anterior cruciate ligament), MCL (medial collateral ligament), or PCL (posterior cruciate ligament) is a major contributor to instability.
-
Meniscus Tears: The meniscus acts as a cushion in the knee joint. Tears can impair its function and lead to instability.
-
Patellar (Kneecap) Issues: A dislocated or improperly tracking patella can cause the knee to feel unstable or give out.
-
Osteoarthritis: As cartilage wears down, the joint can become less stable.
-
Muscle Weakness: Weakness in the quadriceps, hamstrings, or hip muscles can contribute to poor knee control.
