How Long Until I Can Work Out After a Total Knee Replacement?

Undergoing a total knee replacement can be a life-changing event, especially if you've been dealing with chronic pain and mobility issues. 

One of the most common concerns for patients undergoing this surgery is the timeline for returning to physical activity. And if you’re an active adult, you’re probably curious about how long it will be before you can get back to your workout routine. 

Understanding the recovery process and setting realistic expectations is key for a smooth and successful recovery. 

Board-certified orthopaedic surgeon Kevin Park, MD, and the team at his private practice in Houston, Texas, specialize in total knee replacements and personalized post-surgery care. 

With years of experience and a commitment to patient-centered care, we’re here to help you regain your mobility and return to the activities you love. 

Keep reading as we explore what you can expect after a total knee replacement.

Understanding knee replacements

A total knee replacement, also known as knee arthroplasty, is a surgical procedure designed to replace the damaged or worn-out surfaces of your knee joint with artificial components. 

We usually recommend this surgery for patients with severe arthritis or significant knee injuries that have not responded to conservative treatments.

During the procedure, Dr. Park removes the damaged cartilage and bone from the surface of your knee joint and replaces them with metal and plastic components. 

These new components are designed to mimic the natural movement of your knee, reducing pain and improving function and mobility.

Recovery after knee replacement

Recovery from a total knee replacement takes place in several stages. Taking care of your body as you move through each stage helps you experience the best possible outcome. 

Here’s what you can expect in the main stages of recovery after a total knee replacement:

Immediately after surgery

In the first few days following your surgery, the focus is on managing pain and preventing complications. 

You begin physical therapy almost immediately so you can start regaining movement in your knee. Simple exercises, such as ankle pumps and leg raises, improve circulation and prevent blood clots.

Early recovery (weeks 1-4)

During the first month, you continue with physical therapy to increase your range of motion and strengthen the muscles around your knee. 

It’s important to minimize your fall risk. Walking aids, such as crutches or a walker, help you move around safely. 

By the end of this phase, most patients can walk short distances without assistance and perform basic daily activities.

Intermediate recovery (months 1-3)

As your recovery progresses, physical therapy becomes more intensive. You work on building strength and endurance in your knee through exercises like leg presses, stationary cycling, and gentle stretching. 

Follow your therapist’s recommendations and don’t push yourself too hard, as overexertion can slow down your recovery. 

Returning to active workouts

Returning to a full workout routine is a gradual process that varies from patient to patient and depends on many factors, including your age, fitness level before surgery, and overall health. 

Dr. Park gives you personalized activity recommendations based on your specific situation. In the meantime, here’s a general timeline for when you might expect to resume different types of physical activities:

Low-impact activities (months 3-6)

Around the three-month mark, you may be cleared to begin low-impact activities such as swimming, cycling, and walking on flat surfaces. 

These activities are gentle on your knee and help you maintain cardiovascular fitness without putting too much stress on the joint.

Moderate-impact activities (months 6-12)

Between six and 12 months post-surgery, you can start moderate-impact exercises like elliptical training, golfing, and light jogging. 

We have you introduce these activities gradually. Listen to your body and avoid any exercises that cause pain or discomfort.

High-impact activities ( 12 months+)

We usually discourage high-impact activities, such as running, skiing, and basketball, even after a full year of recovery. These activities place significant stress on your knee and increase the risk of injury or wear on the artificial joint. 

Always consult with Dr. Park before attempting any high-impact exercises once you’ve had a knee replacement.
