Knee Pain

Knee pain is a very common complaint. Symptoms can have a sudden onset due to injury or may come about gradually worsening over time. Knee problems can cause an ache or a sharp pain, clicking, stiffness, locking or giving way. These symptoms are often experienced during walking, running, stair climbing or turning in bed.

Structures that can be affected at the knee joint include the ligaments, surrounding muscles, patellofemoral joint, menisci (cartilage), nerves, or the knee joint itself. Common ligament injuries of the knee include tears/ruptures of the Anterior Cruciate Ligament (ACL), Medial Collateral Ligament (MCL), Lateral Collateral Ligament (LCL) and less commonly, the Posterior Cruciate Ligament (PCL). Ligament injuries most often occur in sports that involve a lot of cutting, pivoting and turning such as soccer, volleyball and basketball. The injury may also occur to the cartilage causing microdamage or tears. Some other common causes of knee pain include degenerative disorders such as osteoarthritis or cartilage degeneration.
