Knee Arthritis Causes, Symptoms, and Treatment

Arthritis usually develops after years of use. It is common in the knees because the knees bear the weight of the body. Over time, the cartilage in the knee wears down and stops protecting the ends of bones in the joint.

Symptoms of knee arthritis include pain, swelling, and stiffness. YOu may have trouble getting up after sitting for long periods. Sometimes the knee might also feel like it locks or catches.

Nonoperative treatment for knee arthritis include injections, physical therapy, taking anti-inflammatories, activity modification, weight loss, bracing, or using a cane/walker. If these are not helpful, an orthopedic surgeon may recommend surgery such as total knee replacement (knee arthroplasty) to relieve pain and preserve mobility.
