Knee buckling is a symptom of knee instability that frequently affects older individuals, [1] especially when putting weight on the knees. [2] Notes
Knee pain is pain caused by wear and tear, such as osteoarthritis or a meniscal tear. Effective treatments for knee pain include physical therapy exercises, [28] pain-reducing drugs such as ibuprofen, joint stretching, [29] [30] knee replacement surgery, and weight loss in people who are overweight. [27]
Knee pain relief of 50% or more following genicular RFA may last from several months to two years, [129] [132] and can be repeated by the same outpatient procedure when pain recurs. [129] Injection of phenol may be used as a neurolytic treatment of sensory knee nerves to relieve chronic pain from knee osteoarthritis. [134] [135]

Complaints of locking sensation in the knee joint can be divided into true locking and pseudo locking. True locking happens when the intra-articular structure (e.g. ligaments) [1] is damaged, or a loose body is present inside the joint, or there is a meniscal tear. The knee can be unlocked by rotating the leg and full movement can be restored.
They may also experience instability in the knee once they resume walking and other activities, as the ligament can no longer stabilize the knee joint and keep the tibia from sliding forward. [9] Reduced range of motion of the knee and tenderness along the joint line are also common signs of an acute ACL injury.
Iliotibial band syndrome (ITBS) is the second most common knee injury, and is caused by inflammation located on the lateral aspect of the knee due to friction between the iliotibial band and the lateral epicondyle of the femur. [2] Pain is felt most commonly on the lateral aspect of the knee and is most intensive at 30 degrees of knee flexion. [2]
The patellar tendon attaches the anterior quadriceps muscles to the tibia via the knee cap. [11] Intense knee pain is usually the presenting symptom that occurs during activities such as running, jumping, lifting things, squatting, and especially ascending or descending stairs and during kneeling. [12] The pain is worse with acute knee impact.
