The knee is one of the largest joints in the human body. Supporting and moving the body, the knees are a key part of the human body.
The knees are made up of three bones – the femur (thighbone), the tibia (shinbone) and the patella (kneecap). These bones are connected by ligaments, cartilage, tendons and muscles.
Pain in the knees is a common complaint amongst adults and it is frequently caused by recreational activities, accidents, and wear and tear from daily activities like walking, bending, standing and lifting. Additionally, runners and athletes who play sports are more prone to knee problems.
While the majority of bruises and cuts heal on their own, certain knee injuries can lead to serious conditions that impair knee function over time.
Here are the five most common knee injuries in Singapore:
The patellar tendon is a thick, fibrous tissue that connects the kneecap (patella) to the shinbone and enables movement such as kicking, jumping, and running.
Jumper’s knee, also known as patellar tendonitis, is caused by irritation or inflammation of the patellar tendon.
This knee injury is usually caused by overuse. It usually affects athletes at the peak of their performance.
Without treatment, a jumper’s knee weakens your tendon, ultimately leading to tendon tears.
A cartilage injury is a fairly common type of injury.
The cartilage is a connective tissue found in many parts of the body such as the knees, hips and others. It acts as a shock absorber and allows bones to move over each other.
Although it is a tough and flexible tissue, it can be damaged by sudden traumas, such as sports injuries, or by gradual wear and tear.
Meniscus is a piece of cartilage in your knee that serves as a cushion and stabilizer of the joint. This cartilage protects the bones from wear and tear. In addition to helping transfer weight from one bone to another, it assists in maintaining knee stability.
The meniscus can tear as a result of acute trauma or age-related degenerative changes.
Contact sports such as football or noncontact sports such as volleyball and soccer can lead to meniscus tears.
Cruciate ligaments are found inside your knee joint. Cruciate ligaments are responsible for regulating the backward and forward movement of your knee.
The knee has two cruciate ligaments: the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL). They consist of two strong, round bands that connect the head of the tibia to the intercondyloid notch of the femur.
The ACL is located to the lateral side, while the PCL is located to the medial side. The two cross each other like a pair of limbs of an X. Their names refer to their placement on the tibia: the ACL attaches to the anterior aspect of the intercondylar region, and the PCL attaches to the posterior aspect. As the ACL keeps the femur from sliding forwards, the PCL keeps the tibia from sliding backwards. The ACL also allows rotation of the knee.
Injuries to the anterior cruciate ligament are one of the most common knee injuries.
Getting medical attention for a knee injury as soon as possible increases the likelihood of a full recovery. Mild knee injuries might heal on their own, but it is advisable to have every injury examined by a doctor or physiotherapist. Pain persisting in your knees may require professional help. Treatment options include physiotherapy, arthroscopic surgery and open surgery.
Knee injuries treatment varies based on the type and severity of the injury and can include physical therapy, immobilization, or surgery.
