Whether you’re just out of hospital or a few weeks into your rehab, this article provides an expert-led framework to help optimise your recovery journey.
What happens during knee replacement surgery
Knee replacement surgery (partial or total) typically involves removing and replacing damaged cartilage and bone with artificial joint implants. Most patients begin physiotherapy within 24 hours to reduce stiffness and promote early movement. This often includes assisted walking, gentle leg movements, and strategies to control pain and swelling.
Hospital stays usually last between 1 and 5 days, after which you're discharged home or to a rehabilitation setting to continue recovery.
Why post-op physiotherapy is essential
Early physiotherapy plays a crucial role in recovery. It helps:
Improve range of motion and walking ability
Rebuild quadriceps strength
Reduce swelling and risk of complications like blood clots
Promote independence in daily tasks
Prevent long-term joint stiffness
A structured physiotherapy plan leads to faster recovery and better long-term results.
Phase-based rehab timeline
Phase 1 (0 - 2 weeks): mobility and pain control
Begin gentle exercises: heel slides, quad sets, and straight leg raises
Use mobility aids like crutches or a walker
Apply ice and elevate the leg to reduce swelling
Prevent blood clots through gentle ankle pumps and regular repositioning
Phase 2 (2 - 6 weeks): strength and gait training
Progress to walking unaided
Start step-ups, seated leg extensions, and light cycling
Aim to achieve around 90–105° of knee flexion by week six
Focus on re-learning how to walk smoothly and safely
Phase 3 (6 - 12 weeks): functional movement and balance
Add functional strength work like squats, step-downs, and stair drills
Train single-leg balance and coordination
Build endurance through longer walks and light resistance work
Phase 4 (3+ months): advanced strengthening and return to activity
Introduce resistance bands, gym-based work, and outdoor exercises
Prepare for hobbies like golf, gardening, or hiking
For athletes, include jogging preparation or sport-specific drills
Sample exercises per phase
Early phase: ankle pumps, assisted heel slides, straight leg raises
Intermediate: mini squats, stationary bike, leg press (light load)
Advanced: lateral steps, single-leg balance, walking on varied terrain
These exercises restore mobility, control, and strength over time.

Common challenges and how to overcome them
Swelling and stiffness: Prioritise ice, elevation, and gentle movement
Pain flare-ups: Adjust your exercise intensity temporarily and follow pacing strategies
Slow progress: Re-assess goals, adapt your routine, and seek guidance
Low motivation: Track your milestones, join group rehab, or enlist a rehab buddy
Staying consistent and supported makes a huge difference in long-term outcomes.
Client story: Liverpool patient recovery

FAQs
When can I drive again?
Usually around 6 weeks post-surgery, depending on your progress and whether it's your right or left knee.
How much knee bend should I have?
The goal is typically 90 degrees by week 2 and 105–110 degrees by week 6–8.
Can I kneel after surgery?
Kneeling can feel uncomfortable but is usually safe. Most people improve their tolerance over time with practice and support.
Is hydrotherapy useful?
Yes, especially in the early stages if weight-bearing is uncomfortable. It can improve flexibility and strength without joint stress.
Do I need a CPM machine?
Continuous Passive Motion machines are rarely required today, as active movement under physiotherapist guidance is more effective.
