Osteoarthritis, also known as wear and tear arthritis, is a common problem for many people after they reach middle age. It is important to know that knee replacement is not the only option for osteoarthritis.
What is Knee Osteoarthritis?
Osteoarthritis is the most common type of knee arthritis. A healthy knee bends and straightens because of a smooth, slippery tissue called articular cartilage. This substance covers, protects and cushions the ends of the leg bones that form your knee. Between your bones, two c-shaped pieces of meniscal cartilage act as “shock absorbers” to cushion your knee joint. Osteoarthritis causes cartilage to wear away.
Key Factors that increase your risk:
How it Happens
Osteoarthritis occurs over time. When the cartilage wears away it becomes frayed and rough. Moving the bone along this exposed section is painful. If the cartilage wears away completely, it can result in bone rubbing on bone. To compensate for the lost cartilage, damaged bones may start to bow outward and form painful spurs. Pain and stiffness are the most common symptoms of knee osteoarthritis. Symptoms tend to be worse in the morning or after a period of inactivity.
Age: The ability of cartilage to heal itself decreases as we age. Osteoarthritis typically affects people middle-aged and older.
Injury: Previous knee injury, such as a sports injury, can lead to osteoarthritis later in life.
Other Injury: If you have had other problems with your knee, such as gout, knee infection, or Lyme’s disease, your risk for osteoarthritis increases.
Overuse: People in occupations that involve repeated kneeling or squatting, or heavy lifting and walking, are vulnerable to repetitive stress injuries in the knee. This makes them more likely to develop osteoarthritis.
Weight: The more you weigh, the more stress you put on your knee joints.
Heredity: Certain genes have been linked to osteoarthritis. Inherited traits, such as being bowlegged, knock-kneed, or double jointed can also put you at greater risk for the disease.
