Preparing your body before undergoing knee replacement surgery is essential for faster recovery, better results, and reduced complications. The right diet and exercises before knee replacement can help strengthen muscles, improve joint flexibility, and boost overall health — ensuring you’re ready for surgery both physically and mentally.
Why Preoperative Preparation Matters
A well-planned pre-surgery diet and exercise routine supports healing and reduces stress on the new joint. It enhances mobility, stabilizes weight, and strengthens the immune system. By focusing on nutrition and movement, you give your body the best chance to heal quickly after surgery.
1. Pre-Surgery Diet for Knee Replacement
Balanced Nutrition for Faster Healing
Your body needs proper nutrients to recover efficiently. A balanced diet before knee replacement should include lean proteins, fiber, vitamins, and antioxidants to support tissue repair and fight inflammation.
Key Foods to Include
-
Protein sources: Chicken, fish, lentils, eggs, and tofu for muscle strength.
-
Fruits & vegetables: Rich in vitamin C, A, and K for joint health.
-
Whole grains: Brown rice, oats, and quinoa to maintain energy levels.
-
Calcium & vitamin D: Dairy, soy milk, and sunlight exposure for bone strength.
-
Healthy fats: Olive oil, nuts, and seeds to reduce joint inflammation.
Hydration and Weight Management
Staying hydrated aids in nutrient absorption and toxin removal. A healthy diet before surgery also helps manage body weight, reducing pressure on the knees during recovery.
2. Best Exercises Before Knee Replacement
Why Exercise Is Crucial
Performing preoperative exercises for knee replacement strengthens muscles around the joint, improves flexibility, and enhances blood flow. This preparation minimizes stiffness and speeds up rehabilitation.
Recommended Exercises
-
Quadriceps sets: Tighten thigh muscles for 10 seconds and release.

Straight leg raises: Strengthens front thigh muscles without stressing the joint.
-
Hamstring curls: Improves posterior thigh strength for better knee stability.
-
Heel slides: Gently increase knee flexibility.
-
Ankle pumps: Boost blood circulation and prevent clot formation.

Glute squeezes: Activate hip muscles that support knee movement.
Frequency
Perform these exercises before surgery at least five days a week. Always consult your orthopedic specialist or physiotherapist before starting any new routine.
3. Supplements and Lifestyle Tips
-
Take vitamin and mineral supplements only as advised by your doctor.
-
Avoid smoking and alcohol to ensure proper healing.
