Causes of Knee Pain:
Injuries:
Sprains and Strains: Overstretching or tearing ligaments and tendons.
Fractures: Breaks in the bones of the knee (patella, femur, tibia).
Meniscus Tears: Meniscus tears involve the injury or damage to the cartilage that cushions the knee joint. This condition occurs when the wedge-shaped cartilage between the thigh and shin bones experiences tearing or disruption.
Anterior Cruciate Ligament (ACL) Tears: Common in athletes, particularly those in sports involving sudden stops and changes in direction.
Medical Conditions:Osteoarthritis: Degeneration of joint cartilage and the underlying bone.
Rheumatoid Arthritis: An autoimmune condition that affects the joints is called rheumatoid arthritis.
Gout: Gout is a condition characterized by the accumulation of uric acid crystals in joints, leading to inflammation and pain. This occurs when there is an excess of uric acid in the body.
Bursitis:Inflammation of the bursae, or fluid-filled sacs, surrounding the knee joint is known as bursitis.
Other Causes:
Tendonitis: Inflammation of the tendons.
Iliotibial Band Syndrome (ITBS): Inflammation of the tissue on the outer part of the knee.
