Frequently Asked Questions About Knee Replacement
What is Knee Replacement?
Knee replacement, also known as knee arthroplasty, is a surgical procedure in which a damaged, worn-out, or diseased knee joint is replaced with an artificial implant. This procedure is most commonly performed to relieve pain and restore function in individuals with severe arthritis (such as osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis) or significant knee joint injury.
Knee replacement surgery can significantly reduce or eliminate knee pain, improve mobility, and enhance your quality of life. It’s especially beneficial if non-surgical treatments have failed to relieve symptoms.
Initial recovery typically takes 3 to 6 weeks, with most patients able to walk with support soon after surgery. Full recovery, including resuming normal activities, may take up to 6 months.
This depends on the extent of arthritis or damage in your knee. Total knee replacement is recommended when the entire joint is affected, while partial knee replacement is suitable if only one part of the knee is damaged.
If you're overweight or inactive, your doctor may recommend weight loss or exercises to strengthen the muscles around the knee before surgery. This can improve surgical outcomes and speed up recovery.
You will experience some pain and discomfort after the procedure, but pain management strategies, such as medications and physical therapy, will be in place. Pain typically decreases significantly within a few weeks.
Physical therapy usually starts within 24 to 48 hours after surgery to help restore mobility and strength. Early therapy is critical to achieving a good outcome.
