Knee pain can be caused by a sudden injury, an overuse injury, or by an underlying condition, such as arthritis. Treatment will vary depending on the cause. Symptoms of knee injury can include pain, swelling, and stiffness.
Osteoarthritis is the most common form of arthritis in the knee. It is a degenerative,”wear-and-tear” type of arthritis that occurs most often in people 50 years of age and older, but may occur in younger people, too. In osteoarthritis, the cartilage in the knee joint gradually wears away.
Ligaments are tough bands of tissue that connect the bones in your body. There are four ligaments in the knee that are prone to injury: Anterior cruciate ligament (ACL) is the most commonly injured knee ligament.
Patellofemoral Pain Syndrome (PFPS)
Patellofemoral Pain Syndrome (PFPS) is a pathology of the knee characterized by pain at the front of the knee joint without any significant structural changes in the knee.
The meniscus is a piece of cartilage that provides a cushion between your femur (thighbone) and tibia (shinbone). There are two menisci in each knee joint. They can be damaged or torn during activities that put pressure on or rotate the knee joint.
Patellar tendonitis is a common injury or inflammation of the tendon that connects your kneecap (patella) to your shinbone (tibia). Your pain may be mild or severe. Anyone can get patellar tendonitis.
Chondromalacia patellae, also known as “runner’s knee,” is a condition where the cartilage on the undersurface of the patella(kneecap) deteriorates and softens.
A dislocated kneecap is a common injury that normally takes about six weeks to heal. It’s often caused by a blow or a sudden change in direction when the leg is planted on the ground, such as during sports or dancing.
A popliteal cyst, also known as a Baker’s cyst, is a fluid-filled swelling that causes a lump at the back of the knee, leading to tightness and restricted movement.
Plica syndrome is an interesting problem that occurs when an otherwise normal structure in the knee becomes a source of knee pain due to injury or overuse.
Osgood–Schlatter disease (OSD) is inflammation of the patellar ligament at the tibial tuberosity. It is characterized by a painfulbump just below the knee that is worse with activity and better with rest.
