Treat your Knee Conditions Early

Your knees are important for daily activities such as walking, running, and sitting, as they maintain the movement of your legs when supporting your body weight. However, they are also the most easily injured part of your body as they are complex joints composed of several components.

The Anatomy Of A Knee

As one of the strongest joints of the body, the knee is made up of 4 main components: bone, cartilage, ligaments, and tendons.

 

The knee is made up of three bones – the femur (thigh bone), the tibia (shin bone), and the patella (knee cap). They are covered by articular cartilage which helps the bones move smoothly against one another. In addition, each knee has two meniscii (plural for “meniscus”) which are two pieces of tough collagen-filled structures between the femur and tibia that stabilise the knee and act as ‘shock absorbers’.

 

Four ligaments (tissue that connects bone to bone) hold the knee joint together and keeps it stable, while two tendons (fibrous tissue that connects muscle to bone) help to ensure mobility in the knee joint.

Causes & Risk Factors of Knee Injuries

Injuries can occur to any parts of the knee joint, especially if there is a sudden twisting force in an unexpected manner. The cartilage and certain ligaments/tendons of the knee joint are susceptible to wear and tear either due to age or persistent overuse (common for athletes). While athletes in certain types of sports are more likely to sustain knee injuries, anyone can get one.

 

The risk factors of sustaining knee injuries include:

 

  • Age as the cartilage in our knees deteriorates over the years
  • Having excess weight because it places additional strain on the knee joints, causing them to wear out quicker
  • A sudden increase in a sporting activity that one is not conditioned to

 

Common knee injuries can be broadly divided into 3 categories: ligament injuries, cartilage/meniscus tears and overuse syndromes.

Ligament Injuries

  • Anterior cruciate ligament (ACL)
  • Posterior cruciate ligament (PCL)
  • Medial collateral ligament (MCL)
  • Lateral collateral ligament (LCL)

Cartilage and Meniscus Injuries

  • Cartilage ulcers
  • Meniscus tears
  • Osteoarthritis (wear and tear, ageing, degeneration)

Overuse Syndromes / Mobility Issues

  • Iliotibial band syndrome
  • Patellar tendinosis
  • Patellofemoral pain syndrome

 

The knee can also suffer from traumatic injuries such as fractures of the patella (knee cap), femur or tibia, or dislocations of the patella.

 

Complex knee conditions

Patients who had previously undergone knee replacement surgery may encounter issues such as persistent pain around the implants, infection of the knee implants, fractures around the implants or loosening of the implants due to wear and tear. These are complex issues which require thorough evaluation and specific skill-sets to be able to be addressed safely and effectively.

 

Common Symptoms of Knee Injuries

While symptoms may vary according to the location and severity of the injuries, common symptoms include:

 

  • Swelling and stiffness
  • Redness and warmth to the touch
  • Weakness or instability
  • Popping or crunching noises
  • Inability to fully straighten the knee

 

It is best to visit the doctor if you are experiencing any of the above symptoms, as ignoring them might result in further complications and reduce your mobility.
