Osteoarthritis: Total Knee Replacement Surgery

Osteoarthritis: Total Knee Replacement Surgery - What it is

Osteoarthritis occurs when the cartilage that cushions the ends of bones in your joints gradually deteriorates. When these cartilages begin to breakdown or damaged, the underlying bones begin to rub together resulting in narrowing of the joint space. Bone spurs (abnormal bone growths) are a common feature of osteoarthritis.
Osteoarthritis symptoms often develop slowly and worsen over time.
