Latest / The Total Knee Success Podcast: Your Essential Resource for Navigating Total Knee Replacement / Episode 109: Five Products You May Not Need After Knee Replacement
Transcript
- 0:00A Cochrane review published in 2014 included
- 0:0224 trials with 1 ,445 people. At six weeks, the
- 0:08people who used CPM could bend their knees about
- 0:12two degrees more on average. Are you ready to
- 0:17get back to what you love after knee replacement?
- 0:19The Total Knee Success podcast is your trusted
- 0:22guide with practical tips, evidence -based strategies,
- 0:25and no fluff. It's not personal medical advice,
- 0:29just solid education to help you manage pain,
- 0:32regain mobility, and get back to living the life
- 0:34you love. Let's dive in. Welcome back to the
- 0:39Total Knee Success Podcast. I'm Michelle. If
- 0:43you're getting ready for knee replacement, you've
- 0:45probably heard from someone who's already had
- 0:48one. Before you finish telling them your surgery
- 0:50date, they're telling you what to buy. They loved
- 0:53their ice machine. They spent hours in a CPM
- 0:56machine. Someone else says you'll want a new
- 0:59bed. You appreciate the help and pretty soon
- 1:01your shopping list costs more than the vacation
- 1:04you're hoping to take when walking feels better.
- 1:07I'm guessing you'd rather avoid buying a pile
- 1:09of equipment you may use for a week and then
- 1:12store in a closet. You're already putting money,
- 1:14time, and effort into surgery. Today we're looking
- 1:18at five purchases worth questioning before you
- 1:21place your order. By the end of this episode,
- 1:23you'll have a straightforward way to compare
- 1:25an expensive option with a simpler one, along
- 1:28with a general idea of what each choice may cost.
- 1:31As always, this episode provides general education.
- 1:34Your own needs, home, and medical instructions
- 1:36may be different. Let me introduce you to Bruce,
- 1:39who lives outside Detroit and has a lot of friends
- 1:42with a lot of opinions. He likes his friends.
- 1:45He also knows that asking one of them about knee
- 1:48replacement can produce a 40 -minute equipment
- 1:50review. before he's taken off his coat. One friend
- 1:54sends him a link to a walk -in tub. Another recommends
- 1:57an adjustable bed. By Thursday, he has recommendations
- 2:01for an ice machine, a CPM machine, and a wooden
- 2:03heel slide board. Bruce looks at the list and
- 2:06says, at this rate, I'll need a second bedroom
- 2:09for the equipment and a second job to pay for
- 2:12it. Bruce takes the list to a preoperative visit
- 2:15with his surgeon and asks about the two medical
- 2:17machines. His surgeon has not prescribed a CPM
- 2:21machine or a circulating cold machine. Later,
- 2:24at a separate preoperative physical therapy visit,
- 2:27Bruce asks about his bathroom, his bed, and the
- 2:30exercises he will be doing. Bruce is fictional,
- 2:34although his shopping list is completely believable.
- 2:37I'm using rounded US dollar examples so you can
- 2:40see the size of the differences. Prices change,
- 2:43insurance coverage varies, and the amount you
- 2:45pay may be different. These are examples, not
- 2:48quotes or a prediction of anyone's expenses.
- 2:52The first item Bruce questions is a walk -in
- 2:55tub or a major bathroom renovation. He has a
- 2:59bathtub with sliding glass doors, and he's concerned
- 3:01about stepping over the side after surgery. A
- 3:04walk -in tub sounds convenient until he sees
- 3:06estimates that can reach several thousand dollars.
- 3:10At his preoperative physical therapy visit, Bruce
- 3:13describes the bathroom he already has and brings
- 3:16measurements and a few photos. His therapist
- 3:18checks whether a shower chair or transfer bench
- 3:21could fit. A shower chair gives you a place to
- 3:24sit once you're inside the tub or shower. A transfer
- 3:27bench extends over the side of the tub, allowing
- 3:29you to sit before moving your legs inside the
- 3:32tub. The American Academy of Orthopedic Surgeons
- 3:35includes a stable shower bench or chair and secure
- 3:39bathroom handrails in its suggestions for preparing
- 3:42your home. Bruce's therapist recommends a transfer
- 3:45bench that adjusts to the height of his tub and
- 3:48shows him how to use it. His sliding glass doors
- 3:51make the opening a little too narrow, so Bruce
- 3:54and a family member remove the doors and replace
- 3:56them with a shower curtain before surgery. They
- 3:59check the bench after adjusting its height and
- 4:01discover that the lower track does not interfere
- 4:04with the setup. Someone else's tub, bench, or
- 4:07door frame may be different, which is why measuring
- 4:09first saves a whole lot of trouble. For a broad
- 4:13cost comparison, an installed walk -in tub can
- 4:16cost several thousand dollars, and some projects
- 4:19go well beyond ten thousand. A basic transfer
- 4:22bench may cost around a hundred dollars. A curtain
- 4:26and rod at a smaller expense if the doors need
- 4:29to come out. Insurance may cover some bathroom
- 4:32equipment when the requirements are met, although
- 4:35permanent renovations are often handled differently.
- 4:38Bruce checks his own coverage before buying anything.
- 4:41The problem Bruce needs to solve is the narrow
- 4:44opening and the high side of the tub. Once the
- 4:47bench gives him a seated way across that edge,
- 4:50the major construction project no longer fits
- 4:52his short -term goal. Using a suitable bench
- 4:56and making a modest change to the doors saves
- 4:58Bruce thousands of dollars compared with a walk
- 5:01-in tub estimate. Someone planning a long -term
- 5:03bathroom renovation may still choose a walk -in
- 5:06tub. Bruce only wants to solve the access problem
- 5:10he has coming up. that he anticipates after surgery.
- 5:15The second item Bruce considers is an adjustable
- 5:17bed. When you're sore, tired, and trying to get
- 5:20comfortable, a bed that moves at the press of
- 5:22a button can sound wonderful. One of Bruce's
- 5:26friends sends him a video and tells him the bed
- 5:28changed everything. Bruce replies, for that price,
- 5:32I assume it also changes the sheets? An adjustable
- 5:35bed may be a purchase you already want for comfort
- 5:38or another health reason. Bruce is considering
- 5:41it only because he expects to elevate his leg
- 5:43after knee replacement. His therapist shows him
- 5:46how to use a leg elevation wedge on the bed he
- 5:49already owns. An adjustable bed and base can
- 5:52cost several hundred dollars, while beds with
- 5:55more features can run into the thousands. A leg
- 5:59elevation wedge may cost around $50. Bruce's
- 6:03existing bed is comfortable and easy for him
- 6:05to get in and out of, so the wedge solves the
- 6:08problem that he is trying to solve. His therapist
- 6:11shows him where to place the wedge so he can
- 6:13follow the positioning instructions for his knee
- 6:15and avoid prolonged pressure on his heel. Leaving
- 6:19a pillow only behind his knee can hold it in
- 6:21a bent position for long periods, which may make
- 6:24regaining full knee straightening more difficult.
- 6:28Bruce tries the recommended setup and he finds
- 6:30it comfortable. Keeping his current bed saves
- 6:33him hundreds or possibly thousands of dollars.
- 6:36Someone who already wants an adjustable bed may
- 6:39decide the added comfort is worth the price.
- 6:42Bruce buys the wedge and takes the adjustable
- 6:44bed off his surgery shopping list. The wedge
- 6:48also has to work within the space he has. He
- 6:51checks that it stays in place and that he can
- 6:53move on and off the bed without catching his
- 6:55foot on it. Those small details determine whether
- 6:59a $50 purchase is useful or simply becomes another
- 7:02object leaning against the wall. The third item
- 7:06on his list is a circulating cold therapy machine,
- 7:09often called an ice machine. Several friends
- 7:13loved theirs, and you may have heard the same
- 7:15enthusiasm. The machine circulates cold water
- 7:18through tubing into a wrap around your knee,
- 7:22allowing longer cold sessions without exchanging
- 7:24a pack every time it warms up. A basic circulating
- 7:28machine may cost around $200 to $300, depending
- 7:32on the model and the wrap included. It also may
- 7:36be covered by your insurance. Reusable knee packs
- 7:39or wraps may cost about $30 each, using a rounded
- 7:43example. A $250 machine compared with two $30
- 7:47packs creates a difference of about $190 before
- 7:51tax and shipping. Coverage varies, so Bruce checks
- 7:55before assuming either choice will be paid for.
- 7:58The research gives him another piece of the comparison.
- 8:01A 2023 review combined seven randomized trials
- 8:05involving 519 people after knee replacement.
- 8:09The researchers compared circulating cold treatment
- 8:12with traditional choices such as ice or gel packs.
- 8:16They found no statistically significant differences
- 8:19in pain, pain machine use, knee movement, or
- 8:23swelling. That review looked at circulating cold
- 8:26without added compression. Some machines combine
- 8:30cold and compression, which is a different treatment.
- 8:34If your clinician recommends a cold and compression
- 8:36device, ask why that particular feature is being
- 8:39recommended and what your plan or insurance may
- 8:42cover. Convenience can be worth paying for. You
- 8:46may prefer the machines wrap or appreciate having
- 8:49cold available without repeated trips to the
- 8:51freezer. Bruce has freezer space and help exchanging
- 8:56packs. So he buys two reusable packs. His friend
- 8:59still loves the machine and Bruce is perfectly
- 9:02happy with his packs. The decision may come out
- 9:06differently in your home. Reusable packs require
- 9:09freezer space and someone has to exchange them
- 9:11as they warm. A circulating machine needs water
- 9:14and ice, has tubing to manage and may be heavy
- 9:17when it's full. Bruce thinks through who will
- 9:20set up each option and where the tubing or extra
- 9:23pack will be stored. That comparison tells him
- 9:26more than the price alone. Whichever option you
- 9:29use, follow the instructions you were given for
- 9:32the skin barrier, temperature, and length of
- 9:34use. Skin around your knee may have areas of
- 9:37reduced sensation after surgery. Check your skin
- 9:40and stop using the cold if you notice a burn,
- 9:43blistering, or a concerning color change. The
- 9:47fourth item is a continuous passive motion machine,
- 9:49usually called a CPM machine. Your leg rests
- 9:53in the machine while a motor slowly bends and
- 9:55straightens your knee. Bruce's friend rented
- 9:58one years ago and remembers spending hours in
- 10:01it. He is certain Bruce needs one too. Bruce
- 10:05asks his surgeon directly. His surgeon explains
- 10:08that CPM is not part of the treatment planned
- 10:10for his uncomplicated knee replacement. Bruce
- 10:14will work on knee movement through the exercises
- 10:16and assisted movements his physical therapist
- 10:18teaches him. The research helps explain that
- 10:22decision. A Cochrane review published in 2014
- 10:25included 24 trials with 1 ,445 people. At six
- 10:31weeks, the people who used CPM could bend their
- 10:34knees about two degrees more on average. The
- 10:38researchers considered that difference too small
- 10:41to support routine use and found no clinically
- 10:43important benefit for pain or everyday function.
- 10:47A 2024 review included six studies with 557 people.
- 10:53Adding CPM to physical therapy did not significantly
- 10:57improve knee movement or satisfaction compared
- 11:00with physical therapy alone. The review also
- 11:03reported higher hospital treatment costs when
- 11:06CPM was added. Buying a knee CPM machine can
- 11:11cost several thousand dollars, though that's
- 11:13not usually what happens. Rental charges depend
- 11:16on the supplier, rental period, delivery, and
- 11:20insurance coverage. If your surgeon prescribes
- 11:23one for a particular reason, follow that plan
- 11:26and ask the supplier what you will owe. Bruce
- 11:29has no prescription and no reason to arrange
- 11:32a rental, so his additional CPM expense is zero.
- 11:37This is where the source of the recommendation
- 11:39becomes important. Bruce's friend is describing
- 11:42what happened during his own surgery several
- 11:44years ago. Bruce's surgeon is making a current
- 11:47decision for Bruce's knee and the treatment planned
- 11:50for him. The friend's experience can be interesting
- 11:53without becoming Bruce's equipment order. When
- 11:57his friend asks about the machine, Bruce says,
- 11:59thanks for the suggestion. My surgeon wants me
- 12:02to start with the exercises my therapist will
- 12:04teach me. The fifth item is specialized equipment
- 12:08sold for practicing heel slides at home. Bruce
- 12:12takes a look online and finds a wooden heel slide
- 12:15board with a moving foot platform, a lighter
- 12:18foot sled, and several different straps that
- 12:20he might purchase. These are self -moved exercise
- 12:24aids, which separates them from a motorized CPM
- 12:28machine. A wooden heel slide board costs about
- 12:31$100, and a foot sled costs about $60. A looped
- 12:35stretching strap costs about $15. Each tool feels
- 12:40and works somewhat differently. The useful question
- 12:43might be which one, if any, helps you perform
- 12:47the movement your therapist has shown you comfortably.
- 12:51Bruce tries the heel slide exercise with a loop
- 12:53strap during physical therapy. The loop gives
- 12:56him a comfortable place to hold while he assists
- 12:58the movement. His therapist also explains that
- 13:01some people use a towel or a clean dog leash
- 13:04they already have at home when it gives them
- 13:06a secure, comfortable grip. You'll see polished
- 13:09wooden boards, plastic sleds, straps and other
- 13:12exercise products online. Some people prefer
- 13:15a guided track and are happy to pay for it. Bruce
- 13:19is comfortable using the strap and likes that
- 13:21he can fold it and place it beside his chair.
- 13:25For Bruce, the strap costs about $45 less than
- 13:28the foot sled and $85 less than a wooden board.
- 13:32A person who already owns a suitable towel, a
- 13:35dog leash or a strap that they already have may
- 13:38not need to buy an exercise aid. Trying the movement
- 13:41with your therapist can help you choose an option
- 13:43that feels comfortable and works with the exercise
- 13:46you were shown. Before Bruce finishes shopping,
- 13:50one more friend sends him an all -in -one joint
- 13:52replacement kit. The contents vary, although
- 13:55many kits bundle several smaller aids, such as
- 13:58a reacher, socket, long -handled shoehorn, dressing
- 14:01stick, leg lifter, or stretching strap. Bruce
- 14:05checks the contents one by one. A kit can really
- 14:08be convenient when you expect to use most of
- 14:10the items and the bundle costs less than buying
- 14:12them separately. Bruce already has the strap
- 14:16he wants and does not need every dressing aid,
- 14:19so he skips the kit. After surgery, Bruce uses
- 14:23his transfer bench, cold packs, elevation wedge,
- 14:26and loop strap while following the care plan
- 14:29for him. He attends his appointments and over
- 14:32time, his knee moves more easily and walking
- 14:35feels better. His progress comes from the care
- 14:38and exercises he follows, rather than a promise
- 14:40attached to any particular product. When his
- 14:44friend asks how everything is going, he says,
- 14:47my knee is moving better, I'm walking better,
- 14:49and I'm glad I found the equipment that's right
- 14:51for me. Your list may look different from Bruce's.
- 14:55Some of these products may be useful to you,
- 14:57and you may simply prefer the more expensive
- 14:59option. Before you buy, identify the exact problem
- 15:03you want the product to solve. compare it with
- 15:05a simpler choice, and check your instructions
- 15:08and insurance coverage. Bruce used the same three
- 15:11questions for every item. What problem am I solving?
- 15:15What less expensive option could solve it? And
- 15:18has my surgeon or therapist recommended something
- 15:21specific for me? Those questions leave room for
- 15:24personal preference. They also make it harder
- 15:27for a friend's favorite purchase to end up on
- 15:30your next credit card statement. Check out the
- 15:33show notes for the research references, general
- 15:36price sources, and home equipment guidance used
- 15:39in this episode. You can see the link to the
- 15:42episode blog post in the show notes as well.
- 15:46In episode 110, we'll turn the question around
- 15:49and look at a few less obvious products that
- 15:52can be surprisingly useful after knee replacement.
