How Long Does It Take to Walk Normally After Knee Replacement?

Are you considering knee surgery and want to know how long till you can get back to your normal life? Knee replacement surgery is a life-changing procedure that can restore mobility and alleviate chronic pain for people with severe knee damage. Whether you’re preparing for surgery or supporting a loved one, we’ll show you the recovery timeline after knee replacement surgery. We’ll focus on when you can expect to walk unassisted, the stages of physical therapy, and factors that can influence your recovery process.

Walking After Knee Replacement Surgery: A Timeline

We asked Dr. Young M Jee, a fellowship-trained knee replacement surgeon, about this topic. “Recovering from knee replacement surgery takes time, but with the right steps, you’ll get your mobility and strength back.”  Here's what you can expect at each stage of your recovery journey:  

Discharge to Three Weeks Post-Surgery

During the first few weeks, your focus will be on reducing swelling and pain while improving mobility. Use crutches, a walker, or another assistive device to help you move around, and rest with your leg elevated above your heart to minimize swelling. Your doctor will also prescribe exercises to strengthen your calf, hamstring, and quadricep muscles. Aim to achieve 120 degrees of knee flexibility so you can easily get in and out of chairs, sofas, and car seats.

Four to Six Weeks Post-Surgery

By this stage, you should be able to walk for at least 10 minutes without needing an assistive device. Your physical therapist will encourage you to increase your walking distances and work toward being more independent. If cleared by your doctor, you may also start driving again.

Eight to 12 Weeks Post-Surgery

Dr. Jee says that, "Generally, as your physical therapy program progresses, you’ll notice significant improvements in mobility. You should be able to walk several blocks and return to activities like swimming or cycling. Around the eight-week mark, you may be able to do low-impact hobbies such as golf, dancing, or yoga if your doctor approves. By the 12th week, you’ll feel more confident walking longer distances and challenging yourself gradually.”

One Year Post-Surgery

Full recovery typically takes up to a year, though you may continue to see improvements for two years. By this point, your knee should feel strong and allow you to participate in most daily activities. At this point, keep building on your progress.

Do's and Don'ts During Knee Replacement Recovery

Following the right guidelines after knee replacement surgery can speed up your recovery and reduce the risk of complications. Here’s what you should keep in mind:

DO’s

Here are a few things you should do:

• Stay active: Carry out prescribed exercises and walk daily to build strength, improve flexibility, and regain mobility.
• Use assistive devices: Use crutches, a walker, or a cane as your doctor recommends to prevent strain or falls.  
• Elevate your leg: Elevate your leg above your heart level to reduce swelling and improve blood flow.
• Physical therapy: Attend all scheduled physical therapy sessions and stick to the at-home exercise routine your therapist prescribes.
• Stay hydrated and eat nutritiously: Maintain a balanced diet rich in protein, vitamins, and minerals to support tissue healing and bone recovery.  
• Follow the doctor’s instructions: Take prescribed medications, follow your doctor's guidelines to care for the wound, and know which activities to avoid.

DON’Ts

Here are some things you shouldn't do:

• Don’t skip exercises: Skipping physical therapy or exercises can delay recovery and limit mobility.  
• Don’t overdo it: Avoid overexerting yourself or engaging in high-impact activities that could damage your new knee.
• Don’t sit for long periods: Sitting for too long can increase stiffness and swelling. Get up and move around periodically.  
• Don’t ignore pain or swelling: While some discomfort is normal, persistent or severe pain and swelling could indicate a problem. If this happens, contact your doctor.
• Don’t twist or pivot on your knee: Until your doctor clears you, avoid movements that stress your knee, such as twisting, kneeling, or squatting.
• Don’t neglect fall prevention: To prevent falls, especially during the early stages of recovery, use handrails, keep your home clutter-free, and wear non-slip footwear.

By following these guidelines, you’ll set yourself up for a smoother and more successful recovery.

5 Effective Exercises After Knee Replacement Surgery

Regaining strength and mobility after knee replacement surgery requires consistent and safe exercises. Here are five excellent exercises to support your recovery:

Heel Slides

Heel slides are a foundational exercise that improves knee flexibility and restores range of motion. To perform this exercise, lie on your back with your legs extended. Slowly slide the heel of your recovering leg toward your buttocks, bending your knee as much as possible. Hold this position for a few seconds before sliding your leg back to the starting position. Repeating this motion gently and consistently will help reduce stiffness and increase knee mobility, especially in the early stages of recovery.

Quad Sets

Quad sets are an excellent way to strengthen your quadriceps muscles without straining your knee. Sit or lie on a flat surface with your recovering leg extended. Press the back of your knee into the floor to tighten the thigh muscles. Hold this contraction for 5 to 10 seconds before relaxing. This simple yet effective exercise helps build strength in the muscles that support your knee, ensuring greater stability and reducing strain as you progress in your recovery.

Straight Leg Raises

Straight leg raises target the quadriceps while also engaging your core muscles. Begin by lying on your back with one leg bent and the other straight. Tighten the thigh muscles of your straight leg, then lift it about 6 to 12 inches off the ground. Hold the position briefly before slowly lowering your leg. This exercise is ideal for building strength in the quadriceps without putting pressure on your healing knee, helping you regain stability and balance.

Seated Knee Flexion

Seated knee flexion is a great way to enhance your knee’s flexibility and range of motion in a controlled manner. Sit on a chair with both feet flat on the floor. Gradually slide the foot of your recovering leg back under the chair as far as you comfortably can, bending your knee. Hold the position for a few seconds, then return to the starting position. Consistently practicing this movement helps you regain the ability to perform daily activities like sitting and standing with ease.

Ankle Pumps

Ankle pumps are a vital exercise for promoting blood circulation and preventing complications like blood clots during recovery. While sitting or lying down, point your toes away from you, then flex them back toward your body. Repeat this motion for several minutes at a time. Although simple, ankle pumps are crucial for reducing swelling, improving blood flow, and supporting overall healing after knee replacement surgery. By incorporating these exercises into your recovery routine, you’ll gradually regain strength, flexibility, and mobility in your knee. Always consult your physical therapist or doctor before starting or adjusting your exercise plan.
