Knee Problems

It is the largest joint in the human body. The knee is a modified hinge joint, which permits flexion and extension as well as slight internal and external rotation. The knee is vulnerable to injury and to the development of osteoarthritis.

Many knee problems are a result of the aging process and continual wear and stress on the knee joint (i.e., arthritis). Other knee problems are a result of an injury or a sudden movement that strains the knee

When you experience pain in your knee, it may be comforting to know you’re not alone. This is an extremely common complaint. Because of that many people ignore it, hoping the discomfort will fade on its own. In many cases, it does. But waiting too long to go to the doctor can lead to long-term damage if you have a serious injury or condition. That’s why you should seek medical attention if you experience any of the following signs:

• Knee gives out
• You hear a popping or crunching noise
• Unable to move your knee or fully straighten it
• Limping
• Weakness or instability
• Swelling, redness or warmth to the touch
• Severe pain that doesn’t subside
• Common Cause of Knee Pain:

Arthritis: Although there are many different kinds of this disease are characterized by joint inflammation, the two that most commonly affect knees are osteoarthritis and rheumatoid arthritis.

• Fractures: The bones of the knee, including the kneecap, can break because of accidents, sports injuries or even stepping wrong.
• ACL Injury: Tearing your anterior cruciate ligament (ACL), which connects your shinbone to your thighbone, can lead to excruciating knee pain.
• Torn Meniscus: You can tear this tough cartilage with a sudden jerking movement or by wearing it down over time.
• Bursitis: Bursae are small fluid sacs that prevent friction in the joint, but they can become inflamed because of overuse.
• Tendinitis: Inflammation or irritation in one or more of the knee’s tendons can lead to pain.
• Dislocation: Dislocation occurs when the kneecap slips out of place
