There are many different knee injuries and medical conditions that can cause an unstable knee. The knee joint depends on multiple ligaments, tendons, muscles and other supportive structures to maintain stability. If you have a knee that feels like it could “give out” or feels unstable, contact the orthopedic specialists at DOCS Health. We offer unstable knee treatment and diagnostic testing at our medical center in Los Angeles.

What Causes an Unstable Knee?

The knee joint is very complex and contains dozens of different components. The knee is a hinge joint, but it must be able to allow the leg to twist and change directions, requiring flexibility. The four main ligaments, the two collateral and two cruciate ligaments, help maintain stability of the femur, tibia and patella in the joint. Plus, a variety of tendons, muscles, cartilage and other structures are needed to maintain a stable knee.

When the knee joint feels “loose” or like it may buckle when in use, it can be caused by a wide variety of issues. Knee instability is a symptom of many different knee injuries and conditions. Some of the many issues that can lead to an unstable knee include:

  • Knee sprains
  • ACL, LCL, MCL or PCL injury or tear
  • Meniscus tears
  • Knee arthritis or osteoarthritis
  • Patellar tendon tear
  • Kneecap dislocation
  • PLC knee injuries
  • Fractures

Unstable knee treatment depends on what is causing the lack of stability. To obtain the right treatment, an accurate diagnosis is needed. Many knee injuries and conditions have similar symptoms, including instability, which is why contacting an orthopedic specialist is important for diagnostic testing and treatment.
