Knee joints will slowly degenerate overtime, but when the protective cartilage that cushions the ends of two bones is significantly worn out, it may cause pain. It usually occurs in the hands, knees, hips or spine. Certain factors may accelerate joint degeneration such as being overweight, repeated stress on the joint, multiple injuries, bone deformities and having certain diseases such as diabetes.
It is a group of diseases characterised by inflammation of the joints and often other parts of the body. Chronic diseases such as rheumatoid arthritis, ankylosing spondylitis or Systemic Lupus Erythematosus (SLE) can cause your joints to be red, tender, swollen and warm.
Patellar (knee cap) fracture
It occurs upon high impact trauma such as a fall or car accident.
Anterior cruciate ligament (ACL) injury
Your ACL runs diagonally to the front of the knee, stabilising your knee joint. Improper landing or an abrupt change in direction of the knee joint can lead to this. Football players are especially at risk.
This can occur when twisting, pivoting, or being tackled during a sport. A pop may be heard or felt in the knee. Meniscal tears can also be a result of ageing or arthritis.
Patellofemoral syndrome (Runner’s / Jumper’s knee)
It is a broad term used to describe pain at the front or around the knee. It can be a result of overuse of the knee joint or misalignment of kneecap. A dull, aching pain at the front of the knee during activities especially bending is the most common symptom.
