Undergoing a total knee replacement can feel like a daunting process. There’s a lot of uncertainty, and while surgeons provide valuable information, they often don’t have enough time to cover every detail about recovery. Our goal with this blog is to give you a clear understanding of what to expect after the procedure and address common questions about the total knee replacement journey in British Columbia.
What to expect in the hospital:
Depending on the type of surgery, you’ll likely stay in the hospital for a few hours to a couple of days, with most people staying 1–2 days. During this time, the focus will be on helping you manage pain, avoid complications, and get you moving safely so you’re ready to go home. Here’s what to expect:
Pain Management: The nurses will give you medication to keep your pain under control, either by mouth or through an IV. Don’t hesitate to let them know if you’re uncomfortable before returning home—they want to make sure you’re feeling well enough to rest, move, and start your recovery. Managing pain is an important part of healing and will help you stay active, sleep better, and complete your exercises more easily.
Monitoring: Your health will be closely watched to catch any signs of infection, blood clots, or other concerns. Compression devices or stockings may be used to improve blood flow and reduce swelling.
Getting Moving: A physiotherapist will usually visit you within a few hours or by the next day to help you sit up, stand, and take your first steps with support. Moving early is important to avoid complications and get you on the road to recovery.
Preparation for Home: Before you leave the hospital, you’ll receive clear instructions on how to care for your incision, take your medications, and will be given a pamphlet or booklet with simple exercises to help the initial phase of rehabilitation.
What to expect the first week:
The first week after surgery is key to setting a strong foundation for your recovery. While it’s normal to feel discomfort, staying proactive and consistent with your care can make a big difference:
Pain and Swelling: It’s common to experience swelling and bruising around the knee. To help reduce inflammation, use ice packs or a compression ice machine (like a CryoCuff) and keep your leg elevated whenever possible. Follow the prescription medication from your doctor closely at this time. If your pain becomes unmanageable, it can be challenging to bring it back under control.
Mobility Aids: You’ll likely need a walker or crutches to move around safely. Gradually increase your walking distance, focusing on good posture and weight-bearing as tolerated.
Wound Care: Keep the incision site clean and dry, and watch for any signs of infection such as redness, warmth, or unusual discharge.
Exercise & Physiotherapy: Gentle exercises such as ankle pumps, quadriceps squeezes, and range-of-motion movements are key to improving circulation, reducing swelling, and preventing stiffness in your knee. These exercises are typically outlined in a booklet or pamphlet provided before you leave the hospital—be sure to follow the instructions closely. This is also a good time to call and schedule your physiotherapy appointment, ideally within 1–2 weeks of your surgery date, to ensure a smooth start to your recovery.
What to expect from physiotherapy:
Physiotherapy plays a crucial role in your recovery after a total knee replacement. Here’s what you can expect:
Initial Session (1-2 Weeks Post-op): During your first visit with a physiotherapist, your range of motion, strength, gait, and overall progress will be assessed. The physiotherapist will also ask about your pain levels, medications, and daily activities at home. You'll complete a few questionnaires to track your progress over time. Based on this evaluation, your physiotherapist will provide you with initial exercise progressions and education.
Follow Up Sessions (Week 0-6): For the first 6 weeks, you'll attend physiotherapy sessions weekly. The focus will be on improving range of motion, reducing swelling, walking, and strengthening key muscle groups. Your goal during this phase is to achieve a knee flexion of 110 degrees and be able to straighten your knee with no more than 3 finger widths of space behind it. You'll begin partial revolutions on a stationary bike and gradually incorporate weight-bearing exercises for your quadriceps, hamstrings, glutes, and calves to enhance strength and mobility.
Follow Up Sessions (Week 6 -12): After the first 6 weeks, you'll see your physiotherapist every other week. At this stage, the focus remains on improving range of motion, with a goal of achieving 120 degrees of knee flexion and full knee extension. You should be able to use the stationary bike for full revolutions and walk up and down stairs without difficulty. By this time, you can also discuss with your surgeon when it's safe to return to driving.
How to manage your pain:
Effective pain management is crucial for a smooth recovery. Here are some strategies to help you manage pain during your rehabilitation:
Medications: Taking pain medication as prescribed is essential for managing discomfort early on. Once pain becomes unmanageable, it can be much harder to control. Starting with good pain management allows you to get enough rest, sleep well, and successfully complete your physiotherapy exercises in the early stages, which is vital for your recovery.
Ice and Elevation: To reduce swelling and alleviate discomfort, apply ice packs or use an ice compression machine (like a Cryocuff) for 15-20 minutes every 2-3 hours. Elevating your leg when resting helps promote circulation, further reducing swelling and aiding the healing process.
Pacing: Be mindful of your daily activities to avoid overexertion. Long periods of standing or walking, such as cleaning or cooking, can hinder your recovery. Instead, break up tasks into short 10-15 minute intervals, ensuring you don’t overdo it and prevent the energy needed for your physiotherapy exercises. This approach helps you balance activity with rest and ensures better pain control.
Mobility Aids: Use your prescribed mobility aids (crutches, walker, or cane) as directed by your physiotherapist or surgeon. These devices are designed to reduce pressure on your operated leg, preventing discomfort and promoting healing. Avoid putting too much weight on the operated leg to prevent unnecessary strain that could delay your recovery.
Physical activity going forward:
Staying active is crucial for your recovery, but balancing activity with adequate rest is key. Here’s what to keep in mind throughout your rehabilitation:
Early Recovery (0-12 Weeks): Begin with short, frequent walks around your home and neighborhood. As you build strength and confidence, you can gradually increase your walking distance. During this period, it’s important to focus on your prescribed physiotherapy strengthening exercises. These exercises will help lay the foundation for improved strength, flexibility, and range of motion as you continue your recovery.
Post-Rehabilitation (3-6 Months): At this stage, low-impact exercises like swimming, cycling, and using an elliptical machine are excellent options to stay active without putting excess strain on your new knee. Continuing to incorporate strengthening exercises for your quadriceps, hamstrings, glutes, and calves will be beneficial for maintaining and improving strength and stability.
Post-Rehabilitation (6 Months and Beyond): If you’re interested in returning to higher-impact activities, such as running, jumping, or contact sports, it’s essential to consult with both your surgeon and physiotherapist. Each person’s situation is unique, and while high-impact exercises can increase wear and tear on the knee replacement, there may be modifications, techniques, and guidance that will help you safely return to the activities you love.
When can you drive again?
The ability to drive depends on several factors, including which leg was operated on, your range of motion, and whether you’re still taking pain medications. Most patients can return to driving within 6 weeks post-surgery, but it’s essential to:
Consult Your Surgeon: Get clearance from your surgeon before getting behind the wheel.
Practice in Park: Practice pressing and releasing the pedals in a parked car to ensure your reflexes are sharp.
When can you return to work?
The timing of your return to work after a knee replacement depends on several factors, including the nature of your job, your recovery progress, and your overall health. Below are some general guidelines to help you plan:
1. Sedentary Work (Office Jobs, Desk Work):
If your job primarily involves sitting and minimal physical activity, you may be able to return to work as early as 2-4 weeks after surgery. However, it's important to ensure you're able to comfortably sit for long periods and manage any swelling or discomfort.
2. Light Duty (Standing, Light Walking):
For jobs that require light standing, walking, or minimal lifting, a return to work may be possible around 4-6 weeks post-surgery, depending on your recovery progress and comfort level.
3. Moderate to Heavy Physical Work (Lifting, Heavy Walking, Kneeling, or Squatting):
If your job involves heavy physical demands, such as lifting, long periods of standing or walking, or frequent squatting or kneeling, you may need to wait 3-6 months before returning to full duties. Your physiotherapist or surgeon can guide you on gradual return-to-work strategies and ensure you're ready for these activities.
