Knee Replacement Recovery Guide
A comprehensive guide to recovery after total or partial knee replacement surgery — from the operating room to returning to full activity.
Recovery Overview
Recovery from knee replacement surgery is an active process — the more consistently you follow your physiotherapy programme, the faster and more complete your recovery will be. Most patients experience dramatic pain relief and are surprised by how quickly they walk, though full recovery and the realisation of the new joint's full potential takes 3–6 months.
Dos and Don'ts After Knee Replacement
Do
- ✓Start physiotherapy and walking exercises on the day of or after surgery
- ✓Use ice packs (20 minutes on, 20 off) to manage swelling
- ✓Elevate the leg when resting to reduce swelling
- ✓Take blood clot prevention medication and wear compression stockings as prescribed
- ✓Attend all physiotherapy sessions — this is the most important determinant of outcome
- ✓Sleep with a pillow under the knee to keep it slightly bent
- ✓Keep the wound clean and dry until fully healed
- ✓Use a raised toilet seat to avoid extreme knee flexion
Don't
- ✗Do not kneel on the replaced knee for the first 3–6 months
- ✗Do not sit on low chairs or sofas that require extreme knee bending
- ✗Do not cross your legs while sitting
- ✗Do not skip physiotherapy sessions
- ✗Do not carry heavy loads until cleared by your physiotherapist
- ✗Do not ignore increasing redness, warmth or fever — signs of possible infection
- ✗Do not stop blood clot prevention medication early
- ✗Do not return to high-impact activities (running, jumping) — these shorten implant life
Knee Replacement Recovery Timeline
Surgery under spinal or general anaesthesia. Physiotherapy begins within hours — the physiotherapist will help you sit at the edge of the bed and perform ankle pumps. A CPM (Continuous Passive Motion) machine may be used. Key milestones: Sitting at edge of bed, Ankle pumps and knee flexion started, Ice applied for swelling.
Twice-daily physiotherapy sessions. Progressive weight-bearing with a walking frame. Stairs training before discharge. Blood clot prevention with injections and stockings. Wound care. Key milestones: Walking 20–30 metres with frame, Bending knee to 90 degrees, Stair practice, Discharge home with physiotherapy plan.
Continue home exercises 3 times daily. Progress from walking frame to crutches to walking stick as strength improves. Swelling is normal and gradually reduces. Ice and elevation after exercises. Key milestones: Walking independently with stick, Knee bending to 100–110 degrees, Stair climbing independently, Wound review at 10–14 days.
Outpatient physiotherapy for strengthening and balance. Increasing walking distance. Most daily activities resumed. Driving typically safe at 4–6 weeks (left knee) or 6–8 weeks (right knee). Key milestones: Walking unaided (no stick), Return to desk work, Driving (left knee), Knee bending to 120 degrees.
Continued strengthening, cycling, swimming. Return to most recreational activities. The knee continues improving for up to 12 months as swelling fully resolves and muscles strengthen fully. Key milestones: Full independent daily activities, Gentle cycling or swimming, Return to golf or light recreational activity, Knee bending ideally >120 degrees.
