Millions of people around the globe suffer from severe knee pain every day. There are many reasons that knee pain can occur, including injuries and strains as well as simply moving in the wrong direction.
Sometimes, doctors can diagnose the cause of knee pain immediately. Other times, the doctor will need to run x-rays and perform many tests. Chondromalacia patella, arthritis, injuries to cartilage, and ligaments are all common causes of knee pain.

Arthritis is the most common cause of knee pain. However, arthritis can also be caused by trauma, hereditary, aging, or obesity. This puts additional stress on the joints. Osteoarthritis is the most common type of knee arthritis.
It is also known as degenerative joint disease. Osteoarthritis refers to the wearing down or degeneration of the cartilage protecting the knee joint. Patients complain of pain, stiffness, and tenderness. They also report a reduced range of motion.
Injuries to Cartilage-
Even the simplest injuries can cause cartilage damage. The menisci are the name of the cartilage in the knee. Its job is to maintain body weight across all the joints. Meniscus tears can be caused by injury or degeneration.
In either case, it is extremely painful. Meniscus tears can cause pain, swelling, tenderness, limited range, and motion, as well as an audible popping sound when the joint is moving.
Injuries to Ligaments-
Over-extension is the most common reason for injuries to knee ligaments. This causes ligaments to tear off or rupture. There are two types of ligaments in the knee: medial collateral and lateral.
All three are very painful and often require surgery. Patients with injured knee ligaments report pain, tenderness, and swelling. They also experience limited mobility.
