Knee Pain
Knee pain is a common problem among people of all ages.
Knee pain can be due to a sports injury, a work related injury or an existing medical condition. The knee is comprised of many intricate parts including cartilage, bone, tendons, ligaments and fluid. The injury or irritation of even one can lead to relentless pain and even limit physical activity.
Anatomy of the Knee
Knee is the largest hinge joint of the body and is lined by an articular cartilage which is lubricated by synovial fluid. It is formed by the articulation of the distal/lower end of the femur and the the proximal/upper end of the tibia . Quadriceps tendon connects the quadriceps muscle to patella. Patellar tendon connects the patella onto the tibia. Ligaments join the bones forming the knee joint and provide stability to the knee
- The anterior cruciate ligament prevents the femur from sliding backward on the tibia
- The posterior cruciate ligament prevents the femur from sliding forward on the tibia
- The medial and lateral collateral ligaments prevent the femur from sliding side to side.
Two C-shaped pieces of cartilage called the medial and lateral menisci act as shock absorbers between the femur and tibia. Knee is surrounded by numerous bursae, which are fluid filled spaces and help in smooth movement of the knee.
