The knee is one of the largest joints in your body. It consists of 3 bones:
These bones are connected by an extensive network of ligaments, cartilage, tendons and muscles.
As the knee is an important structure responsible for movement and weight-bearing, it is important to understand the conditions that may affect its function and how to care for your knees.

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.

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:

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.

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:
