- 0:28regain mobility, and get back to living the life
- 0:31you love. Let's dive in. Welcome back to the
- 0:36Total Knee Success Podcast. I'm Michelle. How
- 0:40long will my knee replacement last? It's a frequently
- 0:43asked question and the research gives us good
- 0:45reason to think in terms of decades. Looking
- 0:49after your replacement over those years includes
- 0:51staying active, preparing for the things you
- 0:53want to do, and knowing when a change needs to
- 0:56be checked. By the end of this episode, you'll
- 0:59have a better idea of how long knee replacements
- 1:01often last, what the research says about activity
- 1:04and longevity, and how to look after your knee
- 1:06while getting the most use from it. In episode
- 1:09118, we focused on an exercise routine. Today,
- 1:13we're connecting that work to the years ahead.
- 1:16A 2019 review by Evans and colleagues published
- 1:19in The Lancet combined long -term studies and
- 1:22National Joint Replacement Registry reports.
- 1:25In the registry data, about 82 out of every 100
- 1:29total knee replacements remained in place without
- 1:33revision surgery at 25 years. Let me repeat that.
- 1:37About 82 out of every 100 total knee replacements
- 1:42remained in place without revision surgery at
- 1:4625 years. Revision is an operation to replace
- 1:50or change some or all of the replacement. That
- 1:54figure counts replaced knees rather than individual
- 1:56people. It describes implant survival, how long
- 2:00the replacement remains without revision. Your
- 2:03comfort and ability to do the things you enjoy
- 2:05are also important parts of your result, and
- 2:09those were separate from the outcome measured
- 2:11by that statistic. 25 years is a research follow
- 2:16-up point. Some people need another operation
- 2:19sooner, while others continue using that same
- 2:21knee replacement beyond the 25 years. This estimate
- 2:26reflects people who had surgery many years ago
- 2:29using the designs and techniques available then.
- 2:32There are no guarantees and each person has their
- 2:35own experience. Your age at surgery, medical
- 2:38history, and the components used, as well as
- 2:41any complications, help shape your individual
- 2:45outlook. A 2025 study by Clement and colleagues
- 2:49published in the Journal of Arthroplasty examined
- 2:52registry data to estimate the chance of needing
- 2:56revision over a person's remaining lifetime.
- 2:59The estimates varied with age at surgery and
- 3:02the design of the replacement. Younger people
- 3:05generally had a higher estimated lifetime risk
- 3:07and different designs also had different estimates.
- 3:12If you'd like to look further into these studies,
- 3:15take a look at the blog post for this episode
- 3:18and you can see the references at the bottom
- 3:20of the page. A lifetime estimate answers a different
- 3:24question from the chance of needing another operation
- 3:27within 10 years. Someone who has surgery at 50
- 3:31has more potential years of use ahead than someone
- 3:34who has it at 80. The study used statistical
- 3:38estimates and did not assess why each person
- 3:41needed a particular design or why revision occurred.
- 3:45The results, therefore, cannot tell you that
- 3:47one design is the best choice for everyone. Your
- 3:50surgeon selects components to fit your anatomy
- 3:53and surgical needs. For your own need, knowing
- 3:57the date of surgery and having the details of
- 3:59your replacement available can help if you later
- 4:02see a different orthopedic practice. Those details
- 4:05allow your clinician to interpret relevant follow
- 4:08-up information for the components you actually
- 4:11have. So what can you do to look after your replacement?
- 4:16Staying active helps you maintain the physical
- 4:18abilities you use every day. We have stronger
- 4:21evidence for those benefits than for any particular
- 4:24exercise habit, adding a specific number of years
- 4:27to a replacement. A 2022 systematic review published
- 4:32in The Knee looked at activity levels among 4
- 4:36,263 people who had undergone a total of 4 ,811
- 4:42knee replacement procedures. Some participants
- 4:45had both knees replaced, which explains why the
- 4:48number of procedures was larger than the number
- 4:50of people. Across the included studies, average
- 4:54follow -up ranged from 4 to 12 years. People
- 4:58who were more physically active did not have
- 5:01a demonstrated increase in revision surgery compared
- 5:04to those who were less active. The studies defined
- 5:08activity differently, and their findings leave
- 5:10uncertainty about individual sports and longer
- 5:14periods of time. Being highly active can include
- 5:18frequent walking or gardening. It does not necessarily
- 5:21mean repeated running or jumping. Still, the
- 5:24findings are reassuring for someone who wants
- 5:26to continue moving and enjoying life with a knee
- 5:29replacement. The American Academy of Orthopedic
- 5:32Surgeons generally favors lower -impact recreation,
- 5:36such as cycling and swimming, over high -impact
- 5:39sports. Running, repeated jumping, contact sports,
- 5:42and pursuits with a greater chance of falling
- 5:44introduce different forces or injury risks. Recommendations
- 5:49to limit those pursuits reflect concern about
- 5:52wear, loosening, or injury, together with incomplete
- 5:56long -term evidence. Research has not established
- 6:00one reliable percentage increase in revengeant
- 6:03risk for every sport or person. A 2024 review
- 6:08by Tioli and colleagues examined research on
- 6:11activity, sports, and the condition of knee replacements.
- 6:15The authors found conflicting results across
- 6:18studies. Some findings were reassuring for more
- 6:21active people, while others raised concerns.
- 6:25Research on particular high -impact sports remained
- 6:28too limited to settle the long -term risk. Much
- 6:32of this research observes what people choose
- 6:34to do after surgery. More active participants
- 6:37may also have better strength, fewer health problems,
- 6:40or a more comfortable knee to begin with. Researchers
- 6:43have to account for those differences when comparing
- 6:46outcomes. An association between activity and
- 6:49another operation cannot by itself establish
- 6:53that the activity caused or prevented a need
- 6:56for the operation. That uncertainty is a reason
- 7:00to make a specific decision about a sport you
- 7:03value. Ask what risks are known for that sport,
- 7:07which concerns are based on limited evidence
- 7:09or professional judgment, and whether changing
- 7:12the intensity or style of play would fit your
- 7:15circumstances. Your experience and preferences
- 7:18can be part of that decision alongside your surgeon's
- 7:21advice. Before starting or returning to a demanding
- 7:25sport, discuss its specific demands with your
- 7:28surgeon. Your prior experience, health history,
- 7:31surgical history, and current abilities can influence
- 7:34the recommendation. Follow any restrictions you've
- 7:37been given. Preparing your body for what you
- 7:40want to do is part of using your new knee well.
- 7:43The 2026 Physical Therapy Guideline supports
- 7:46progressive strengthening and training for balance
- 7:49and walking after knee replacement. Adequate
- 7:51knee motion also helps you perform the movements
- 7:54your chosen pursuit requires. As the demands
- 7:57increase, your preparation needs to reflect them.
- 8:01Suppose you want to return to social dancing.
- 8:03You may be comfortable walking around the neighborhood,
- 8:06while moving backward, turning with a partner,
- 8:08and continuing through several songs still need
- 8:11practice. You can build toward those demands
- 8:14with appropriate strength, balance, motion, and
- 8:17gradually longer practice. A therapist can help
- 8:20you assess what you need before you increase
- 8:22the challenge. That preparation supports control
- 8:25and participation. It cannot guarantee that an
- 8:29injury will never happen or tell us exactly how
- 8:32long your replacement will last. Along with staying
- 8:36active, ongoing orthopedic care helps check how
- 8:40your replacement is doing. wear or changes in
- 8:43how the components are attached to your bone
- 8:45can develop gradually. An examination and x -rays
- 8:49can help your surgeon assess those changes, including
- 8:52some that may produce few symptoms early on.
- 8:55Follow -up is an opportunity to check the replacement
- 8:58and discuss whether your knee is working comfortably
- 9:01for what you do. There are different recommendations
- 9:05for when to return. The American Association
- 9:07of Hip and Knee Surgeons generally recommends
- 9:10a visit every three to five years after the initial
- 9:13post -operative period with the interval adjusted
- 9:16to the person. The UK SAFE recommendations take
- 9:20a different approach for selected people after
- 9:23an uncomplicated first replacement. Routine visits
- 9:26may be omitted between years 1 and 10 when the
- 9:29components meet specified standards for a strong
- 9:32track record and prompt orthopedic assessment
- 9:34is available if symptoms develop. Those recommendations
- 9:38include a clinical assessment and x -ray at 10
- 9:42years with later review based on findings. People
- 9:46with a more complex surgery or a previous revision
- 9:49may need a different plan. Your surgeon can tell
- 9:53you which schedule fits your circumstances. If
- 9:55you've lost track of that plan, ask the office,
- 9:59when would you like to see me again for my knee
- 10:00replacement? Keep that plan available so you
- 10:03know when to arrange your next visit. Between
- 10:06visits, contact your doctor about new pain that
- 10:09persists or increases, unexplained swelling,
- 10:12giving way, or a noticeable loss in motion or
- 10:14walking ability. Explain when the change started,
- 10:17whether it settles or keeps getting worse, and
- 10:20what has become harder to do. Several conditions
- 10:23can cause similar symptoms, so an assessment
- 10:26helps determine what's happening and what care
- 10:29may help. That care may include another course
- 10:32of physical therapy. You can return after your
- 10:34original therapy has ended for a specific problem
- 10:37with strength, knee motion, balance, or walking.
- 10:40After evaluating your symptoms, your orthopedist
- 10:42may refer you for treatment directed at those
- 10:44limitations. I see people who have had knee replacement
- 10:47and come back to therapy later because they're
- 10:50still having difficulty with something they want
- 10:52to do. We assess what's limiting them and work
- 10:55on a plan that fits their needs. For more education
- 10:58on pain, my book, Making Sense of Pain After
- 11:01New Replacement, explains the topic in everyday
- 11:04language. You'll find a link in the episode notes.
- 11:08Some symptoms do need more urgent action. Infection
- 11:12around a replacement is uncommon but can occur
- 11:14even years after surgery. New or worsening pain
- 11:18with redness, warmth, swelling, drainage, fever,
- 11:21or chills calls for prompt medical evaluation.
- 11:24Infection can occur without a fever, so seek
- 11:27help based on the changes you're noticing. New
- 11:30significant calf pain or swelling also needs
- 11:32prompt medical assessment because a blood clot
- 11:35is one possible cause. Sudden chest pain or shortness
- 11:38of breath requires emergency evaluation. Knowing
- 11:42which changes to report and having a follow -up
- 11:44plan gives you a way to respond if a problem
- 11:47develops. For day -to -day life, you can keep
- 11:50building the abilities that support what you
- 11:52enjoy. Many people use their knee replacements
- 11:54for decades. Staying active, preparing for greater
- 11:58demands, and getting help when something changes
- 12:00can support those years of use. If you'd like
