Intro
Knee replacement surgery, also known as knee arthroplasty, is a common surgical procedure used to replace a damaged or arthritic knee joint with an artificial one. The goal of the surgery is to alleviate pain, restore mobility, and improve overall quality of life. However, to achieve optimal results, it's crucial to engage in a rehabilitation program that includes exercises specifically designed to strengthen the muscles surrounding the knee joint. In this article, we will explore seven essential knee replacement exercises with pictures to help you understand the movements and proper techniques.
Understanding the Importance of Knee Replacement Exercises
Knee replacement exercises are vital for a successful recovery after surgery. These exercises help to:
- Improve range of motion and flexibility
- Strengthen the surrounding muscles, including the quadriceps, hamstrings, and hip flexors
- Enhance balance and stability
- Reduce pain and inflammation
- Promote healing and tissue repair
