Knee Arthritis

Knee arthritis is the gradual wearing down of the cartilage that cushions the knee joint, most commonly from osteoarthritis. It typically develops over years and becomes more common with age, prior knee injuries, and higher body weight. It is one of the leading causes of activity-limiting knee pain in adults.

Common symptoms

  • Knee pain that worsens with activity and improves with rest
  • Stiffness, especially in the morning or after sitting
  • Swelling that comes and goes
  • Grinding, crunching, or creaking sensations
  • Gradual loss of motion or a sense the knee is less reliable

When to see a specialist

Arthritis care usually starts non-surgically, exercise, physical therapy, weight management, medication, and sometimes injections, and many people manage well for years this way. Consider seeing a surgeon when pain regularly limits walking, sleep, or activities you care about despite that care. An evaluation does not commit you to surgery; it clarifies where you stand and what your options are.

Common questions

Does knee arthritis always lead to knee replacement?
No. Many people manage arthritis for years, or indefinitely, with exercise, weight management, and other non-surgical care. Replacement is typically reserved for advanced arthritis that significantly limits quality of life.
Can knee arthritis be cured?
Worn cartilage does not grow back, so treatment focuses on reducing pain and preserving function. That said, symptoms can often be improved substantially without surgery.
What surgical options exist?
Depending on the pattern of wear, options may include partial or total knee replacement, robotic-assisted replacement, or, for isolated cartilage defects in younger patients, cartilage restoration procedures. A joint replacement surgeon can match the option to your knee.
