Chronic knee pain can make even simple activities like walking and climbing stairs difficult. For many patients, knee replacement surgery is one of the best ways to move forward. 

 One of the most common questions people ask is, "How long does knee replacement take?" While the surgery usually takes about 1 – 2 hours, the process (including preparation, recovery, and rehabilitation) requires several weeks of time and planning. 

At Southwest Hip and Knee in Tempe, AZ, Dr. Amber Randall helps patients understand what to expect before, during, and after surgery so they can feel prepared each step of the way. Call now to book an appointment and get started. 

Is knee replacement surgery permanent? 

A frequent question patients ask is, "Is knee replacement surgery permanent?" While almost no medical procedure is indefinite, most modern implants are designed to last 15 – 20 years or longer. For many patients, a replacement may function well for the rest of their lives. 

Factors like age and overall health may influence how long an implant lasts. Following post-surgery instructions and maintaining a healthy lifestyle also play a big role in preserving your results. A good orthopedic surgeon focuses on creating personalized recovery plans that help patients maximize the long-term benefits of knee replacement. 

Your surgical timeline: What to expect 

The procedure for knee replacement typically takes up to two hours. During this time, the damaged portions of the joint are removed and replaced with parts that mimic the function of a natural knee. Patients spend additional time in pre-op and post-op recovery areas, so the full timeline is usually several hours to a few nights in the hospital. 

While the surgery is relatively short, the overall healing process takes longer. Understanding the recovery time for knee replacement helps patients set realistic expectations. 

Recovery time for knee replacement 

Initial recovery typically takes 6 – 12 weeks, though full recovery can take longer. Most patients use a walker or crutches for the first few weeks and gradually transition to a cane or walking independently. During a pre-surgery consultation in Tempe, AZ, Dr. Randall can provide a more detailed recovery timeline. 

How to improve mobility after surgery 

Want to know how to improve mobility after knee replacement surgery? Dr. Randall may recommend physical therapy to prevent chronic knee pain and stiffness. Over time, patients progress from simple exercises to more advanced activities like climbing stairs, swimming, or cycling. By committing to these routines, patients can experience big improvements in both mobility and quality of life.
