Most knee injuries are caused by an external force bending or twisting the knee in a manner that it was not anatomically designed for. The vast majority of knee injuries are from a twisting mechanism from falls, sports, or accidents. This twisting can cause damage to the ligaments and cartilage.
High-force injuries such as sports injuries and motor vehicle accidents can disrupt multiple parts of the knee anatomy, causing multiple types of knee injuries.
Bursitis can be caused by overuse, arthritis, degenerative joint disease, injuries from kneeling, infection, or gout.
Knee injuries can be prevented by taking steps to reduce the risks:
Maintain fitness and lower-body strength
Stay at a healthy weight
Wear proper shoes for your sport
Train properly for your sport and do not overtrain
Maintain the playing surface for sports in optimum condition
Avoid slippery or uneven surfaces
Avoid loose turf or gravel
Wear knee braces and pads if required by your sport or suggested by your doctor
Do all rehab exercises if you have had a previous knee injury
Treat osteoporosis if you have it
Make sure your home is safe to avoid falls
