Knee replacement surgery is a common and effective procedure for people suffering from severe knee pain, arthritis, or joint damage. While the surgery can significantly improve mobility and quality of life, recovery is a gradual process that requires patience, proper care, and consistent rehabilitation.
Understanding what to expect after surgery can help you prepare better and recover more confidently. This article explains the recovery timeline, essential tips, and common concerns after knee replacement.
