Knee surgeries are medical procedures aimed at treating various knee problems, such as injuries, arthritis, or other conditions affecting the knee joint. Common types of knee surgeries include arthroscopy, where a small camera is inserted to diagnose and treat issues, and total knee replacement, which involves replacing damaged cartilage and bone with artificial components. Recovery from knee surgery varies depending on the procedure and the individual's health. Physical therapy is often recommended to help restore strength and mobility. Patients may need to use crutches or a brace during the initial healing phase to support the knee as it recovers.
