Arthritis is the most common reason that the knee joint wears out. Arthritis happens from chronic inflammation inside the joint, which wears out the protective cartilage around the bone and weakens the joint capsule and ligaments. As the protective cartilage is worn away, bone begins to rub on bone, which causes pain and makes it harder to move.
There are many options for treating knee pain caused by a joint wearing out. Usually, the doctor will try to treat the knee pain with conservative, or nonsurgical treatment.
Conservative treatment includes:
Weight loss
Activity changes
Physical therapy
Walking aids, such as a cane or walker
Medication, and
Control of medical conditions
Patients with knee arthritis and pain usually do not get better with time, and often the symptoms get worse.
A total knee replacement, also called total knee arthroplasty, is a surgical procedure that is performed thousands of times each year, to replace a worn out knee joint, improve the motion of the knee, and relieve pain.
