Pre-Surgical Physiotherapy (Prehab)
Starting physiotherapy before your knee replacement surgery — called prehabilitation — has been shown to significantly improve post-surgical outcomes. Stronger quadriceps and hamstrings before surgery mean faster recovery afterwards. Prehab also teaches you the exercises you will need post-op, so they feel familiar when it matters most.
Week 1–2 Post-Surgery
The focus is on controlling swelling through ice and elevation, gentle range-of-motion exercises (ankle pumps, quad sets, heel slides), and safe ambulation with a walker. Pain is managed with appropriate medication, and the physiotherapist monitors wound healing.
Week 3–6: Progressive Strengthening
Weight-bearing is increased progressively. Exercises include straight leg raises, mini squats, step-ups, and stationary cycling. Walking distance increases daily. Many patients transition from a walker to a cane during this phase.
Week 6–12: Functional Recovery
Goals shift to full range of motion, independent stair climbing, driving (if applicable), and return to daily activities. Strengthening exercises become more challenging and functional.
After 3 Months
Most patients are independent with daily activities by 3 months. Continued home exercise, regular walking, and occasional physiotherapy sessions help optimise long-term outcomes. Swimming and cycling are excellent low-impact activities to maintain joint health.
Realistic Expectations
A new knee joint typically lasts 15–20 years with proper care. Physiotherapy plays a critical role in ensuring you get the most out of your implant by maintaining muscle strength, flexibility, and joint health.
