Basics With All About Seniors: Knees
Knee problems and seniors have an ongoing relationship over the years. They start from minor knee problems and gradually result in knee replacements. The daily movement of the body do not cause the problems, but surprisingly the symptoms and the pain develop from everyday wear and tear, overuse or injuries. They often occur during recreational or sports activities, work-related tasks or home projects. Then how to evaluate what movement is right for the knees? In order to understand more about it and problems related to knees, let’s first know about Knees.
What is a Knee Joint?
A knee is a complex joint that connects thigh bone (Femur) to the leg bone (tibia). It is the largest joint in the body. The two bones are separated by two discs (menisci). The upper leg bone and lower leg bone are connected by ligaments, tendons, and muscles. Whereas the surface of the bones inside the knee joint is covered by articular cartilage, which absorbs shock and helps in smooth, gliding surface for joint movement.
A person involved in sports, recreational activities, people growing old or having diseases such as osteoporosis or arthritis increase their chances of having knee problems. Joint cartilage usually wears out because of the ageing process, leading to osteoarthritis. Wearing out can also be caused by different forms of arthritis, such as rheumatoid arthritis, post-injury arthritis, etc.
Sudden Acute Injuries
Acute injuries are the most common causes of knee problems. They can be caused by a direct blow to the knee or due to an abnormal twist, bending, or falling on the knee. These wear and tear cause pain, bruising or severe pain in the joint. Acute injuries include:-
- Sprains, strains or other injuries to the ligament and tendons that connect and support the kneecap.
- A tear in the rubber cushion of the knee joint (meniscus).
- Ligament tears.
- Fractures of the kneecap. Fractures on the lower portion of thigh bone or upper part of the tibia or fibula are mostly caused by the signs of abnormal force. These abnormal forces are, falling on the knee, a severe twisting motion, severe force that bends the knee, or when the knee forcefully hits an object.
- Pieces of bone or tissue from a fracture or dislocation that may get caught in the joint and interfere with movement.
- Knee joint dislocation. This is a rare injury that requires great force and requires immediate medical attention.
Overuse injuries occur with repetitive activities or prolonged pressure on the knee. Activities such as stair climbing, bicycle riding, jogging or jumping stress joints and other tissues and can lead to irritation and inflammation. Overuse injuries include:
- Inflammation of the small sacs of fluid that cushion and lubricate the knee.
- Inflammation of the tendons or small tears in tendons
- Thickening or folding of the knee ligaments
- Pain in the front of the knee from overuse, injury, excess weight or problems in the kneecap.
- Irritation and inflammation of the band of fibrous tissue that runs down the outside of the thigh.
Conditions That May Cause Knee Problems
- Osteoarthritis (degenerative joint disease) may cause knee pain that is worse in the morning and improves during the day and often develops at the site of a previous injury. Other types of arthritis, such as rheumatoid arthritis, gout, and lupus, also can cause knee pain, swelling, and stiffness.
- A popliteal (or Baker's) cyst causes swelling in the back of the knee.
- Infection in the areas of skin (cellulitis), joint (infectious arthritis), bone (osteomyelitis), or bursa (septic bursitis) can cause pain and decrease the knee movement.
- A problem in the hip or a pinched nerve can also sometimes cause the pain.
- If a piece of bone or cartilage or both lose blood supply (Osteochondritis dissecans), it causes pain and decreases the movement of the knee joint.
Knee problems can be cured without any treatment if identified at the right time. Preventing yourself from having a knee replacement will be simple if followed the right path. Therefore, look out for more information that we are going to provide you with for your knees to be healthy and happy.
