Post-Surgical Rehab Timeline After Knee Replacement

Knee replacement surgery is a major procedure that can dramatically improve your quality of life by reducing pain and restoring function. However, the success of your surgery largely depends on your commitment to the rehabilitation process. Understanding what to expect during each phase of recovery can help you prepare mentally and physically for the journey ahead.

Pre-Surgery Preparation (1-2 Weeks Before)

Your recovery actually begins before surgery. Pre-surgical physical therapy, also called "prehab," can significantly improve your outcomes:

• Strengthen the muscles around your knee
• Improve your range of motion
• Learn post-surgery exercises and techniques
• Prepare your home for recovery
• Practice using assistive devices like crutches or walkers

Phase 1: Hospital Recovery (Days 1-3)

Goals: Pain management, prevent blood clots, begin gentle movement

Recovery in the hospital focuses on:

• Pain and swelling management
• Gentle range of motion exercises
• Getting out of bed and taking first steps
• Learning to use assistive devices safely
• Basic strengthening exercises

Phase 2: Early Recovery (Weeks 1-6)

Goals: Reduce swelling, restore basic mobility, prevent complications

Week 1-2: Focus on Healing

• Gentle range of motion exercises
• Ankle pumps and calf raises
• Quad sets and glute squeezes
• Walking with assistive devices
• Ice and elevation for swelling

Week 3-6: Building Foundation

• Increase walking distance gradually
• Begin stationary bike (if comfortable)
• Straight leg raises
• Heel slides for flexibility
• Basic balance exercises

Phase 3: Intermediate Recovery (Weeks 6-12)

Goals: Restore normal walking, improve strength and flexibility

During this phase, most patients can:

• Walk without assistive devices (with doctor approval)
• Drive (usually around 6-8 weeks for right knee)
• Return to light activities and work (desk job)
• Begin more challenging exercises
• Start low-impact activities like swimming

Phase 4: Advanced Recovery (Months 3-6)

Goals: Return to normal activities, optimize function

Focus areas include:

• Advanced strengthening exercises
• Sport-specific training (if applicable)
• Balance and proprioception training
• Return to recreational activities
• Long-term maintenance program

Key Milestones to Expect

Warning Signs to Watch For
