Knee Replacement Rehab - Your 12-Week Recovery Plan (Ipoh)
Quick answer: Total knee replacement rehab is a 12-week structured progression with clear weekly milestones. Success depends on 3 things: early range-of-motion recovery (target 110-120° flexion by week 8), progressive strengthening of quadriceps and glutes, and managing swelling and pain smartly. Most Ipoh patients attend physio 2-3x/week in weeks 1-6, then taper. Typical return to driving: 4-6 weeks. Full function: 3-6 months; continued improvement up to 12 months.
Before Surgery - Prehab Matters
- Quadriceps strength at surgery strongly predicts 12-week outcome
- 4-6 sessions of prehab (strength, range, practice walking with crutches, home set-up) improves recovery speed
- Home preparation: declutter, raised toilet seat, shower stool, non-slip surfaces, stair rails
Weeks 1-2 - Hospital and Early Home Phase
Goals
- Wound healing
- Swelling control
- Range of motion: 0° extension fully, 90° flexion
- Safe walking with frame or crutches
- Transfer (bed-chair-toilet) independence
Daily Routine
- Ankle pumps: 20 reps hourly
- Quad sets: 10 × 5-second holds, 4x/day
- Heel slides: 10 reps, 4x/day
- Short arc knee extension (0-40°): 10 reps, 3x/day
- Straight leg raises: as quad strength allows
- Ice and elevate: 15-20 minutes after each exercise session
Warning Signs
- Severe increasing pain, redness, wound discharge - surgeon review
- Sudden calf swelling or chest pain - possible DVT/PE - emergency
- Fever > 38°C - review
Weeks 3-4 - Building Confidence
Goals
- Range of motion: 100° flexion
- Walking with one crutch or stick
- Climbing a few stairs with rail
- Reduced swelling
Exercises
- Seated knee extension with ankle weight (light)
- Mini-squats holding chair or counter
- Heel raises
- Step-ups onto 10 cm step
- Stationary cycling with high seat, low resistance if comfortable
Physiotherapy
- 2-3 sessions per week
- Manual therapy for knee range
- Supervised progression of strength
- Scar mobilisation once fully healed
Weeks 5-8 - Strengthening Phase
Goals
- Range of motion: 115-120° flexion
- Walking unaided on flat surfaces
- Climbing stairs reciprocally (one leg per step)
- Confidence in sit-to-stand without using arms
- Return to driving for most patients (automatic car, right knee cleared)
Exercises
- Wall squats (deeper over time)
- Step-ups on higher step
- Lunges (stationary, partial range)
- Side-stepping with resistance band
- Stationary cycling with moderate resistance
- Balance exercises: single-leg stance, tandem walking
- Pool-based walking and gentle exercises (after wound fully healed, ~week 4-6)
Physiotherapy
- 1-2 sessions per week
- Progressive resistance training
- Functional re-education
Weeks 9-12 - Functional Return
Goals
- Range of motion: 120-125° flexion (enough for most daily tasks)
- Return to normal walking pattern
- Stair climbing with confidence
- Return to light recreational activity
- Return to driving for all patients (manual car review)
Exercises
- Full bodyweight squats within comfort
- Single-leg stance with challenge (eyes closed, foam)
- Longer walks (30+ minutes)
- Stationary bike increasing resistance
- Gentle swimming and pool walking
- Low-impact exercise classes (tai chi, yoga, pilates with modifications)
Physiotherapy
- 1 session per week or fortnightly
- Functional and recreational goal-setting
- Plan for 3-12 month maintenance
Months 3-12 - Continued Gains
- Continued range of motion gains are possible up to 12 months
- Strength and stamina continue to improve
- Resume hiking, light jogging (surgeon dependent), doubles badminton, golf
- Avoid high-impact running and jumping sports long-term

Frequently Asked Questions
When can I drive after knee replacement? Typically 4-6 weeks for the right knee in an automatic car. Left knee or manual - often 2-3 weeks sooner. Must be off strong painkillers and able to perform emergency stop.
How many physio sessions will I need? Typical 15-25 sessions over 12 weeks. Some patients need more for stiffness management.
Is it normal for the knee to feel warm and swollen for weeks? Yes - mild warmth and swelling for 3-6 months is common. Severe or worsening redness needs review.
Will I ever kneel again? Many patients can kneel comfortably after 6-12 months on a padded surface. Some find it always uncomfortable - varies.
Can I walk on stairs alternately again? Yes - most patients return to reciprocal stair climbing by weeks 6-10.
How long will my replacement last? Modern knee replacements last 15-25 years in most patients.
Is hydrotherapy useful after knee replacement? Yes - once the wound is fully healed (usually week 3-4), hydrotherapy accelerates range and strength.
Can I go back to running? Generally discouraged long-term for joint longevity. Walking, cycling, swimming, elliptical, golf, and doubles badminton are fine.
