📅 Mar 15, 2026•⏱ 4 min read
Knee replacement is one of the most successful orthopedic procedures in the world. But the real transformation happens after the surgery — during recovery, rehabilitation and long-term lifestyle changes.
1. The first week after surgery
- Day 1: most patients stand and walk with support
- Day 2–3: physiotherapy begins — bend the knee, strengthen thigh muscles, improve balance
- Day 4–7: walk to the bathroom, sit on a chair, climb a few stairs, basic exercises
2. The first month after surgery
- Week 2–3: pain reduces, swelling decreases, walking becomes easier
- Week 4: most patients walk without support, resume light household activities and can travel home
3. Long-term recovery (months 2–6)
- Walk 2–3 km daily
- Climb stairs comfortably
- Sit cross-legged (in some cases)
- Drive a car (after 6–8 weeks)
- Strong quadriceps, improved balance, full knee extension
4. Exercises after knee replacement
- Essential: straight leg raises, heel slides, knee bends, quad sets, ankle pumps
- Advanced: stationary cycling, swimming, light jogging (after 3–4 months)
5. Activities to avoid
- Running on hard surfaces
- Jumping
- Heavy lifting
- Deep squatting
- High-impact sports
6. Diet for faster recovery
- High-protein foods
- Calcium-rich foods
- Vitamin D supplements
- Hydration
- Avoid sugar & fried foods
