The knee is an important structure in the body that is responsible for movement and weight-bearing. It is one of the largest joints in the body and consists of an extensive network of cartilage, ligaments, menisci, and surrounding muscles and tendons. The knee joint consists of 3 bones:
A knee injury can be a result of sports or recreational activities, accidental falls, and daily wear and tear. Minor injuries may heal on their own but certain knee injuries can lead to serious conditions that affect knee function in the long run.
Knowing how to spot the symptoms of a knee injury can prevent it from worsening. Learn about common knee conditions and orthopaedic treatments available at Mount Elizabeth Hospitals.
The anterior cruciate ligament (ACL) is one of the main stabilising ligaments in the knee. ACL tears are common in sports that involve start-stop movements, pivots or sudden changes in direction. Examples of these sports include football, netball, tennis, dancing and skiing.
If your ACL ruptures, you may:

The meniscus is a small, C-shaped cartilage that acts as a cushion in your knee joint. There are 2 menisci that protect the knee joint from wear and tear and help to stabilise it.
The meniscus can be injured or torn. This may happen during movements that forcefully rotate the knee while the foot is firmly planted, such as when you play basketball or football.
Symptoms of a meniscus tear include:

Anterior knee pain is pain and inflammation on the underside of the kneecap (patella), at the front and centre of your knee.
Anterior knee pain can be caused by many different reasons. It can result from:
It often affects young people who play sports and older people who overwork their knees.
Common symptoms include a dull aching pain in the front of the kneecap. This pain can be aggravated by kneeling, squatting, running, sitting cross-legged, and stair climbing.
Your doctor will perform a physical examination to check for bone alignment, muscle strength and joint stability.
Anterior knee pain often improves with rest, changes to your activity and exercise. Surgery is rarely needed. Your doctor may recommend:

The patellar tendon connects the shin bone (tibia) to the kneecap (patella). It works with the muscles in front of the thigh area to straighten the leg. Patellar tendonitis, also called jumper's knee, is an injury to the patellar tendon.
Patellar tendonitis is characterised by:

Patellar tendon ruptures or tears may occur due to injuries or age-related wear and tear
You may experience a tearing or popping sensation when a patellar tendon tears. Other common symptoms include:

As you age, your bone strength decreases. Osteoporosis is a condition in which your bone tissues break down faster than your body can rebuild them, leading to brittle and weak bones.
Hip fractures are generally caused by accidents. Older people with osteoporosis have a higher risk of hip fractures as their bones are generally weaker.
If you have a hip fracture, you are likely to experience:
