The knee contains four main types of elastic ligaments that aid in strength and stability. All four of these ligaments can become torn, resulting in potentially serious mobility issues. For example, ACL tears can occur suddenly, accompanied with a sensation of the knee completely giving out. Moreover, athletes and other physically active people are more prone to multi-ligament injuries where more than one ligament is injured.
In instances such as these, reconstructive surgery might be required. While there are more than 80 forms of arthritis , osteoarthritis and rheumatoid arthritis are both known to cause knee buckling in patients. Osteoarthritis is a degenerative condition that creates a breakdown in joint cartilage, leading to increased joint friction in the process.
The femoral nerve runs from the pelvis down to the front of the leg and aids in muscle movement. With femoral nerve dysfunction, damage to the femoral nerve results in a loss of sensation in certain parts of the leg.
