Knee Replacement Recovery: A Week-by-Week Rehabilitation Guide

01Week 1–2: Protection and Early Movement

The first two weeks often focus on managing swelling and pain while beginning gentle movement. Some swelling is common after surgery, but a sudden increase, marked redness, wound changes, fever, calf pain, or breathlessness should be reported promptly to the surgical or medical team.

Key goals:

• Achieve full knee extension (straightening) — this protects the joint
• Begin gentle flexion (bending) exercises
• Practice safe bed transfers and standing with support
• Walking short distances with a walker or crutches

Cold therapy may be suggested during this phase, if it is safe for you and permitted by the surgical team. Follow their instructions for duration, skin protection, and frequency rather than using a fixed schedule.

02Week 3–6: Restoring Range of Motion

By week 3, the goal is progressing knee flexion toward 90 degrees. Most daily activities — sitting comfortably, climbing stairs, getting in and out of a car — require at least 90–100 degrees of flexion.

Exercises at this stage include:

• Heel slides and wall slides for flexion
• Straight leg raises for quadriceps strength
• Short arc quads
• Seated knee flexion and extension

Walking distance gradually increases. Most patients transition from a walker to a cane around weeks 4–6 depending on strength and balance.

03Week 6–12: Strengthening and Function

This phase is about rebuilding the muscle strength that was lost before and after surgery. The quadriceps and gluteal muscles are the primary focus.

• Step-ups and mini squats
• Leg press (low resistance, high repetitions)
• Balance and proprioception training
• Stair climbing with increasing confidence

Return to driving depends on the operated side, medication, strength, reaction time, insurance, and local guidance. Ask the surgeon or physiotherapist when an emergency stop and other driving tasks can be performed safely.

04Month 3–6: Return to Full Activity

By month 3, most patients are walking without any aid. The focus shifts to building endurance, returning to recreational activities, and achieving the full range of motion the implant allows.

05The Most Common Mistakes

1. Skipping physiotherapy: Missing planned sessions or home practice can make it harder to review movement and progress. Discuss barriers with the treating team rather than stopping without advice.
2. Pushing through sharp pain: Discomfort during exercise is normal. Sharp, acute pain is a signal to stop.
3. Neglecting the extension: Patients often focus on bending but lose extension. Full extension is actually more important — a bent knee at rest causes long-term problems.
