Knee Replacement Recovery: Complete Week-by-Week Timeline

Knee replacement (total knee arthroplasty) is one of the most successful orthopaedic surgeries, but recovery requires dedication, patience, and consistent physiotherapy. This guide walks you through each week of recovery so you know what to expect and how to optimise your outcomes.

Weeks 1-2: Hospital Stay and Early Recovery

Your hospital stay typically lasts 1-3 days. The focus is on pain management, swelling reduction, and gentle movement. You will begin physiotherapy within 24 hours of surgery, starting with ankle pumps, quad sets, and gentle knee bending. You will use a walker and be instructed on safe movement.

Weeks 3-6: Transitioning to Daily Life

You will transition from walker to cane around weeks 3-4. Outpatient physiotherapy begins 2-3 times per week. Goals include achieving 90-110 degrees of knee flexion, straightening the knee fully, and walking with improved gait. Stationary cycling and gentle strengthening exercises begin.

Months 2-3: Building Strength

This phase focuses on progressive strengthening. Exercises include squats, lunges, step-ups, and leg press. Balance training improves stability. Most patients can drive after 4-6 weeks (left knee) or 6-8 weeks (right knee). Walking without a cane becomes comfortable.

Months 3-6: Advanced Rehabilitation

Strengthening intensifies with heavier resistance. Walking distance and stair climbing improve significantly. Range of motion continues to improve. Many patients return to work (sedentary jobs) around 6-12 weeks, manual jobs may require 12-16 weeks.

Months 6-12: Return to Full Activity

Full strength recovery takes 6-12 months. Low-impact activities like swimming, cycling, and golf are encouraged. High-impact activities (running, jumping) are generally discouraged. Most patients are very satisfied with their outcomes by 12 months.
