Knee replacement, also called knee arthroplasty or total knee replacement, is a surgical procedure to resurface a knee damaged by arthritis. Metal and plastic parts are used to cap the ends of the bones that form the knee joint, along with the kneecap. In determining whether a knee replacement is right for you, an orthopedic surgeon assesses your knee's range of motion, stability and strength.

Hip replacement is surgery to replace a worn-out or damaged hip joint. The surgeon replaces the old joint with an artificial joint. This surgery may be a choice after a hip fracture or for severe pain because of arthritis. The goal of hip replacement surgery is to replace the parts of the hip joint that have been damaged. It also helps relieve hip pain that can’t be controlled by other treatments.

Arthroscopic knee surgery may be a treatment option for certain types of knee pain. Arthroscopic surgery is a procedure that involves inserting a small camera inside the joint. Through other small incisions, instruments can be inserted to repair or remove damaged structures. Arthroscopic knee surgery is often called "scoping the knee" or knee arthroscopy.
