Overview

In the world of orthopedics, the success of a knee replacement is 50% surgery and 50% rehabilitation. “Pre-hab” (pre-surgical exercise) and post-operative physiotherapy are the pillars of a fast recovery. For patients in Delhi preparing for surgery with Dr. Ashish Jain, strengthening the muscles around the knee joint is the best way to ensure the new implant functions at its peak. This guide covers the essential exercises to prepare your body and the movements that will get you back on your feet.

The Power of Pre-hab: Why Start Before Surgery?

Many patients believe they should rest before surgery. However, the stronger your quadriceps and hamstrings are before the operation, the easier it will be to walk after it. Pre-hab helps reduce hospital stay duration and improves joint range of motion immediately after the procedure.

Essential Pre-Surgery Exercises

1. Ankle Pumps: Lying flat, flex your feet up and down. This improves circulation and prepares you for the post-op blood clot prevention routine.
2. Thigh Squeezes (Quad Sets): Tighten the muscle on the top of your thigh by pushing the back of your knee into the bed. Hold for 5 seconds.
3. Straight Leg Raises: While lying down, keep your leg straight and lift it 6 inches off the bed. This builds the core strength needed to lift your leg into a car or bed post-surgery.

Post-Surgery Rehabilitation: Phase-by-Phase

Phase 1: Days 1–14 (Restoring Circulation and Mobility)

Immediately after surgery at Max Hospital, the goal is to prevent stiffness.

• Knee Straightening: Place a small towel roll under your ankle to let gravity straighten the knee.
• Bed-Supported Knee Bends: Slowly slide your heel toward your buttocks while lying down.

Phase 2: Weeks 3–6 (Building Functional Strength)

Once the stitches are removed, the intensity increases.

• Sitting Knee Extensions: While sitting in a chair, slowly straighten your leg and hold.
• Mini-Squats: Holding onto a sturdy table, perform very shallow squats to engage the glutes and quads.

Phase 3: Week 7 and Beyond (Endurance and Balance)

• Stationary Cycling: This is the best low-impact exercise to regain full range of motion.
• Step-Ups: Using a small step, practice leading with the operated leg to regain balance.

Safety Precautions

Never force a movement that causes sharp pain. While “discomfort” is normal during stretching, “pain” is a signal to stop. Always perform these under the guidance of a qualified physiotherapist.

Conclusion

Movement is medicine. By committing to a structured exercise program both before and after your knee replacement, you are investing in the longevity of your implant. Under the expert supervision of Dr. Ashish Jain, patients who stay active through their recovery journey experience significantly better outcomes and a much faster return to the vibrant Delhi lifestyle.
