Complete timeline of knee replacement surgery — from your first consultation to full recovery. What happens at every stage, explained clearly for patients.
If surgery is recommended, you'll schedule a pre-operative visit 2-4 weeks before surgery for blood work, EKG, medical clearance, and surgical planning. If your surgeon uses robotic technology, a CT scan maps your knee in 3D.
Arrival: 2 hours before surgery for check-in, gown change, IV placement, and anesthesia consultation.
Anesthesia: Most knee replacements use spinal anesthesia (numbs below the waist) with sedation, or general anesthesia (fully asleep). Your anesthesiologist will recommend the safest option.
The procedure: Takes 1-2 hours. The surgeon removes damaged cartilage and bone, then implants metal and plastic components. The new joint is tested for alignment, stability, and range of motion before closing.
Immediately after: You'll wake in the recovery room. A nerve block keeps your leg numb and pain-free for 12-24 hours. Physical therapy often begins the same day — standing and taking a few steps with a walker.
Week 1: Ice, elevation, gentle exercises. Walker or crutches for all movement. Pain managed with medication (many surgeons now use multimodal protocols that minimize opioid use). Physical therapy visits begin.
Weeks 2-3: Increased walking distance. Transition from walker to cane for some patients. Driving resumes for left knee (automatic transmission) around week 2-3. Staples/sutures removed at 2-week follow-up.
Weeks 4-6: Most patients walking without a cane at home. Driving resumes for right knee. Return to desk work. Swelling and stiffness gradually improving.
Months 2-3: Range of motion approaching normal. Walking 30+ minutes. Swimming and stationary bike. Most daily activities resumed.
Months 3-6: Continued strengthening. Low-impact activities (golf, cycling, hiking). Maximum improvement in range of motion.
Months 6-12: Final 10% of recovery. Most patients report feeling "normal" by 6-12 months. Full benefit of surgery realized.
Pain relief: Over 90% of patients report significant pain relief. Most describe the remaining discomfort as "different" than arthritis pain — and much more manageable.
Range of motion: Most patients achieve 0-120 degrees (full extension to deep bend). This is enough for all daily activities, walking, cycling, and most recreational sports.
Activities you CAN do: Walking, swimming, cycling, golf, doubles tennis, hiking, dancing, gardening, travel.
Activities to AVOID: Running, jumping, basketball, soccer, skiing moguls, heavy squatting. High-impact activities accelerate implant wear.
Implant lifespan: Modern implants last 20-25 years with normal use. Over 90% of implants are still functioning well at 15 years.
