Knee Pain / Osteoarthritis

Knee-Pain-Osteoarthritis

Knee

It is one of the weight-bearing joints that are vulnerable in stress caused by everyday activities such as walking, running, lifting, and other activities in standing position.

The knee joint is composed of Femur (upper leg bone), Tibia (lower leg bone), and the patella (kneecap). Knee joints have four major ligaments that help to stabilize and hold the bones together, Anterior Cruciate Ligament (ACL), Posterior Cruciate Ligament (PCL), Lateral Collateral Ligament (LCL), and the Medial Collateral Ligament (MCL). Group of muscles and their tendons (a tough fibrous band that connects the muscle to bone to generate movement) are the Quadriceps muscles (in front of the thigh) are responsible for knee extension (knee straight), and Hamstrings muscles (back of the thigh) responsible for knee flexion (knee bending).

Knee pain

It is a common complaint among adults that most often associated with wear and tear conditions, and with athletes that have a jumping or running sports that usually caused by lack of training or injuries. This can happen to any of the joint structures depend on the cause, for adults, it usually happens to the cartilage in which wear and tear are common. For athletes, ligament and meniscus sprain/tear is the most common reason for knee pain.

Though knee pain is most common with aged and athletes, this can affect people of all ages. Physical activity, obesity, hip, and ankle joint problem may also affect the knee and may cause knee pain in which the surrounded structures are also affected that causes the limit of knee joint functions.

Common signs and symptoms of the knee injury

  • Pain
  • Swelling
  • stiffness
  • Decrease or loss of function
  • Limited range of motion
  • Unstable
  • Unbalanced
  • Difficulty in walking

Most common causes of knee pain

  • Osteoarthritis
  • Ligament injury
  • Meniscus injury
  • Patellar Malalignment
  • Tendonitis
  • Osteoarthritis
  • It is one of the types of arthritis in which wear and tear of the cartilage are happening and mostly affected are the aged and obese people. It is when the cartilage or the soft cushion in between the bone of the knee is worn-out and the protective space between the bones decreases thus can result in the bone to bone rubbing and may produce painful bone spurs.
  • Ligament injury
  • There are four ligaments in the knee that can be sprain or torn depends on the mechanism of injury, but the most common to be sprain is the Anterior Cruciate ligament (ACL), second is the Medial collateral ligament (MCL). Depend on how the injury happened, ACL and MCL tear can be injured together. ACL’s mechanism of injury is sudden stop while foot flat on the floor and the MCL mechanism of injury is twisting or pivoting while foot flat on the floor. Both can be tear when a sudden stop and pivoting were done. Ligaments are responsible in stabilizing the joint, having a sprained or torn knee ligaments may feel unstable and difficulty in walking and balancing, changes in structures and swelling may affect the joint functions and the range of motion. The special test can be used to check which ligament is affected and to rule out other knee injuries.
  • Meniscus injury
  • Menisci are the soft cushion in between the femur (upper leg bone) and tibia (lower leg bone) that serve as the shock absorption and connect the two bone. There are two menisci, the lateral and the medial. The most likely to injured is medial, it is usually accompanied with ACL and MCL injury (they are called the unhappy triad of O’donoghue), it is caused by a hard blow on your knee that causing the three structures to be injured. But the mechanism of injury of the meniscal tear is a varus force (outward) or valgus force (inward) when the knee is bent. The special test can be used to check which side is affected and to rule out other knee injuries.
  • Patellar Malalignment
  • This usually happens when the quadriceps muscle (front thigh muscle) specifically the Vastus Medialis Oblique (part of the quadriceps muscle located in inner thigh) is weak or when your Iliotibial band (muscle on the lateral thigh) is very tight. But with an injury and direct blow to the knee that pushes the patella may also be the reason for patellar malalignment.
  • Tendonitis It is an inflammation of a tendon that can be a result of overuse in physical activities such as running and jumping. The most common knee tendonitis is the patellar tendonitis or the jumper’s knee, this often occurs when doing a high impact from jumping to the ground repeatedly. Pain can be aggravated when climbing stairs or walking in an inclined.
