Osteoporosis is a condition that results in the weakening of an individual's bones. Typically, this occurs in the latter stages of life. Those that have osteoporosis have a higher risk of experiencing a bone fracture. In fact, because their bones are weakened, there's a chance that they may damage one of their joints – knee, wrist, and hip fractures are some of the more common osteoporosis-related injuries, which often necessitates joint replacement surgery.
