knee surgery is a medical procedure aimed at repairing or replacing damaged structures in the knee joint. Common reasons for this surgery include injuries, arthritis, or other degenerative conditions. The procedure can involve various techniques, such as arthroscopy, where small instruments are used to fix issues, or total knee replacement, where the entire joint is replaced with an artificial one. Recovery from knee surgery typically involves physical therapy to restore strength and mobility. Patients may need to use crutches or a brace during the initial healing phase. The overall goal is to reduce pain and improve function, allowing individuals to return to their daily activities.
