Osteoarthritis is the most common type of arthritis and affects 8.75 million people in the UK.
However, knee osteoarthritis in particular, has become a major worldwide public health problem.
According to Arthritis Research UK, the knee is one of the joints most commonly affected by osteoarthritis.
This is because the knees, like the hips, bear a lot of bodyweight.
Symptoms include pain, stiffness, creaking sound, hard swellings and soft swellings.
Additionally, according to Arthritis Research UK, it can cause your knee to give way, it doesn’t move as freely, knees become bent and bowed, and muscles around your joint look thin or wasted.
There are a number of factors that increase your risk, including if you’re over 40 years, a woman, you’re overweight, there’s a family history and if you’ve had a knee injury or operation.
Another reason could be performing repetitive activity that causes ‘wear and tear’ on the joints.
According to research published in the journal Clinical Orthopaedics and Related Research in 2007, doing these floor positions regularly throughout your lifetime increases your likelihood of knee osteoarthritis.
It has become a popular gym move, but performing lots of squats could increase risk.
The position involves crouching or sitting with knees bent and heels close to or touching the buttocks or thighs.
The ancient yoga pose is where legs are crossed but feet are placed on top of the opposing thigh.
Over time it can place increased pressure on the knee joints.
Side knee bending
Any kind of bending can mean the knee is overused, and side-knee bending in particular.
A 2013 study published in the journal Arthritis Care and Research found that frequent knee bending was associated with a higher prevalence of knee cartilage lesions, which are related to osteoarthritis.
