The knee is a vulnerable joint that bears a great deal of stress from everyday activities, such as lifting and kneeling, and from high-impact activities, such as jogging and aerobics.
Knee pain affects nearly 35% of adults that has resulted in poor functionality of the knee joint.
1. Tibia- shin bone or larger bone of the leg.
2. Femur- thighbone or upper leg bone.
3. Patella- kneecap.
Each bone end is covered with a layer of cartilage that absorbs shock and protects the knee.
There are 2 groups of muscles involved:
1. Quadriceps muscles (located on the front of the thighs), which straighten the legs
2. The hamstring muscles (located on the back of the thighs), which bend the leg at the knee.
Tendons are tough cords of tissue that connect muscles to bones.
Ligaments are elastic bands that connect bone to bone. Some ligaments on the knee provide stability and protection of the joint, while other ligaments limit forward and backward movement of the tibia.
1. Arthritis- Osteoarthritis is the most common type of arthritis that affects the knee. It is a degenerative process where the cartilage in the joint gradually wears away.
Rheumatoid arthritis can also affect the knees by causing the joint to become inflamed and by destroying the knee cartilage.2. Torn cartilage (meniscus)
3. Synovitis and tendonitis (Jumper's knee)
4. Sprain or Ligament injury- Due to sudden twist to knee or blow to knee. Common ligament injury are:
ACL (Anterior Cruciate Ligament)5. Fracture around knee
6. Combined injury
Arthritis can cause the cartilage to wear away. Loss of the protective lining can cause painful bone on bone rubbing.
While the symptoms of knee arthritis may be tolerated with some medications, lifestyle adjustments and physiotherapy
if symptoms persist even after above mentioned ways then knee replacement is the only way to reduce pain, restore function and improve the quality of life.

Knee joint replacement is a surgery to replace a knee joint with a man-made artificial joint, is called a prosthesis.
Damaged cartilage and bone are removed from the knee joint. Man-made pieces are then placed in the knee.
Knee arthroscopy is surgery that uses a tiny camera (arthroscope) to look inside your knee to check for problems inside your knee joint
Knee arthroscopy is recommended if you have a painful condition that does not respond to nonsurgical treatment.
