Knee surgery is a medical procedure aimed at treating various knee problems, such as injuries, arthritis, or other conditions that cause pain and limit movement. The surgery can involve repairing damaged ligaments, removing loose cartilage, or even replacing the entire knee joint with an artificial one. This helps patients regain mobility and reduce discomfort, allowing them to return to their daily activities. Recovery from knee surgery typically involves physical therapy and rehabilitation to strengthen the knee and improve flexibility. Patients may need to use crutches or a brace during the healing process. With proper care and guidance from their doctor, many individuals can enjoy a more active lifestyle post-surgery.
