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

Before Surgery: Prehabilitation

The best knee replacement outcomes start before surgery. Prehabilitation (prehab) - physiotherapy done in the weeks before your operation - is proven to speed recovery and improve results.

Your pre-surgery physio programme should include:

• Quadriceps strengthening - strong thigh muscles protect your new knee
• Range of motion exercises - maintain as much knee flexibility as possible
• Upper body strengthening - you will need arm strength for crutches and getting up from chairs
• Practice with crutches or a walker - learn safe walking technique before surgery

In Melaka, major hospitals performing knee replacements include Mahkota Medical Centre, Pantai Hospital Melaka, and KPJ Puteri Specialist Hospital. Government options include Hospital Melaka's orthopaedic department.

Weeks 1-2: The Critical Early Phase

This is the hardest part, but also the most important. Starting physiotherapy early - ideally within 24 hours of surgery - is essential.

Goals:

• Bend knee to 90 degrees by end of week 2
• Walk with a walker or crutches
• Manage swelling with ice and elevation
• Perform basic exercises: ankle pumps, quad sets, straight leg raises

What to expect: Pain and swelling are normal. Your physiotherapist will visit you in hospital and guide your first steps.

You will likely go home within 3-5 days.

Tip: Do your exercises even when it hurts. Gentle movement actually reduces swelling and stiffness.

Skipping exercises is the number one cause of poor outcomes.

Weeks 3-6: Building Strength

Goals:

• Walk with a single crutch or cane
• Climb stairs (one at a time)
• Bend knee to 110 degrees
• Reduce reliance on painkillers

Physiotherapy includes:

• Progressive strengthening exercises for quads, hamstrings, and glutes
• Stationary cycling (excellent for knee range of motion)
• Balance exercises
• Scar tissue management
• Gait retraining - learning to walk with a normal pattern again

Most patients transition from hospital-based physiotherapy to outpatient clinic visits during this phase. Sessions are typically 2-3 times per week.

Weeks 6-12: Returning to Normal Life

Goals:

• Walk without any walking aid
• Bend knee to 120+ degrees
• Resume driving (usually at 6-8 weeks, check with your surgeon)
• Return to light activities and social outings

Physiotherapy focuses on:

• Functional exercises - getting in/out of cars, navigating uneven ground
• Continued strengthening with resistance bands and light weights
• Confidence building with outdoor walking on real surfaces
• Preparing for return to work (if applicable)

By week 12, most patients are walking normally and managing daily activities independently. Physiotherapy sessions reduce to once a week.

Months 3-12: Full Recovery

Your new knee continues to improve for up to a year after surgery. During this phase:

• Continue your home exercise programme daily
• Gradually increase walking distance and activity level
• Low-impact activities like swimming, cycling, and tai chi are excellent
• Avoid high-impact activities like running and jumping long-term

Costs in Melaka:

• Private physiotherapy: RM80-200/session, typically 20-30 sessions total
• Government hospital: RM5-30/session

The investment in physiotherapy is small compared to the surgery itself, but it makes or breaks your outcome. Patients who complete their full rehab programme report significantly better knee function and satisfaction 5 years later.

The First Two Weeks - Protecting the Healing Joint

The early post-operative window sets the stage for the whole recovery. Typical Melaka protocols have patients sit out of bed within 24 hours of surgery, begin walking with a frame on post-op day one to two, and progress to two crutches before discharge.

Daily bed exercises start immediately - ankle pumps every hour, quadriceps sets, gluteal squeezes, and gentle heel slides. Ice to the knee for 20 minutes every two hours in the first five days controls swelling and reduces narcotic needs.

Cold-gel pack wraps rented from medical supply shops in Melaka make this practical. The single most important goal in the first two weeks is full knee extension (the knee straightening fully) - losing this window creates a stiff knee that is hard to recover.

Contraindications and Movement Cautions

Several movements and positions require caution during early rehab. Do not rest the knee on a pillow under the joint - this encourages a flexion contracture that is the main preventable complication of knee replacement.

Support the leg straight with the calf on a pillow or towel if swelling is significant. Do not kneel directly on the operated knee for at least 12 weeks - and for some patients, this is never comfortable again.

Avoid prolonged sitting with the knee at 90 degrees in the first four weeks - get up and walk every hour. Avoid uncontrolled falls; use walking aids until your physiotherapist has cleared independent walking.

Do not drive until the surgeon has cleared - typically 4–6 weeks for the right knee, earlier for the left if automatic transmission.

Red Flags Requiring Surgical Review

Contact your surgeon or present to Hospital Melaka or Pantai Hospital Melaka emergency department for: fever above 38°C, redness, warmth, or discharge from the wound, sudden increase in pain after the first week of recovery, calf pain and swelling (possible deep vein thrombosis), shortness of breath or chest pain (possible pulmonary embolism), new loss of ability to straighten or bend the knee that was previously achievable, any trauma or significant fall onto the operated knee, or any crepitus or clicking with pain that wasn't there before. Post-operative complications are time-sensitive; do not delay.

Week-by-Week Functional Milestones

Reasonable targets to track your progress. Week 2: full extension (0 degrees), flexion to 90 degrees, walking 100 metres with frame.

Week 4: flexion to 110 degrees, walking 500 metres with one crutch, climbing one flight of stairs reciprocally with a handrail. Week 6: flexion to 120 degrees, walking independently indoors, sit-to-stand without pushing up with hands, driving cleared for most left-knee cases.

Week 8: walking outdoors with single stick or unaided, climbing stairs reciprocally without pain. Week 12: most normal activities resumed, including gardening, light recreation.

Month 6: near-peak function. Month 12: full recovery plateau for most patients.

If you are behind any of these by more than a week, discuss with your physiotherapist rather than pushing harder independently.
