Danette Lake thought surgical procedure would relieve the ache in her knees.
The arthritis ache started as a boring ache in her early 40s, introduced on largely by the strain of undesirable weight. Lake managed to lose 200 kilos by means of weight-reduction plan and train, however the ache in her knees endured.
A sexual assault two years in the past left Lake with bodily and psychological trauma. She broken her knees whereas combating off her attacker, who had damaged into her residence. Although she managed to flee, her knees by no means recovered. At occasions, the sharp ache drove her to the emergency room. Lake’s job, which concerned loading baggage onto airplanes, usually left her in distress.
When a physician mentioned that knee substitute would scale back her arthritis ache by 75 p.c, Lake was overjoyed.
“I thought the knee replacement was going to be a cure,” mentioned Lake, now 52 and dwelling in rural Iowa. “I got all excited, thinking, ‘Finally, the pain is going to end and I will have some quality of life.’”
But one 12 months after surgical procedure on her proper knee, Lake mentioned she’s nonetheless struggling.
“I’m in constant pain, 24/7,” mentioned Lake, who is just too disabled to work. “There are times when I can’t even sleep.”
Most knee replacements are thought-about profitable, and the process is understood for being safe and cost-effective. Rates of the surgical procedure doubled from 1999 to 2008, with 3.5 million procedures a 12 months anticipated by 2030.
But Lake’s ordeal illustrates the surgical procedure’s dangers and limitations. Doctors are more and more involved that the process is overused and that its advantages have been oversold.

Research means that as much as one-third of those that have knees changed proceed to expertise chronic pain, whereas 1 in 5 are dissatisfied with the outcomes. A study published last year in the BMJ discovered that knee substitute had “minimal effects on quality of life,” particularly for sufferers with much less extreme arthritis.
One-third of patients who endure knee substitute might not even be applicable candidates for the process, as a result of their arthritis signs aren’t extreme sufficient to benefit aggressive intervention, in response to a 2014 examine in Arthritis & Rheumatology.
“We do too many knee replacements,” mentioned Dr. James Rickert, president of the Society for Patient Centered Orthopedics, which advocates for reasonably priced well being care, in an interview. “People will argue about the exact amount. But hardly anyone would argue that we don’t do too many.”
Although Americans are getting old and getting heavier, these components alone don’t clarify the explosive development in knee substitute. The improve could also be fueled by a better charge of accidents amongst youthful sufferers and medical doctors’ higher willingness to function on youthful folks, comparable to these of their 50s and early 60s, mentioned Rickert, an orthopedic surgeon in Bedford, Ind. That shift has occurred as a result of new implants can last more — maybe 20 years — earlier than sporting out.
Yet even the most recent fashions don’t final without end. Over time, implants can loosen and detach from the bone, inflicting ache. Plastic parts of the synthetic knee slowly put on out, creating particles that may trigger irritation. The put on and tear may cause the knee to interrupt. Patients who stay overweight after surgical procedure can put further strain on implants, additional shortening their lifespan.

The youthful sufferers are, the extra possible they’re to “outlive” their knee implants and require a second surgical procedure. Such “revision” procedures are harder to carry out for a lot of causes, together with the presence of scar tissue from the unique surgical procedure. Bone cement used within the first surgical procedure additionally might be troublesome to extract, and bones can fracture because the older synthetic knee is eliminated, Rickert mentioned.
Revisions are additionally extra more likely to trigger issues. Among sufferers youthful than 60, about 35 p.c of males want a revision surgical procedure, together with 20 p.c of girls, in response to a November article in the Lancet.
Yet hospitals and surgical procedure facilities market knee replacements closely, with adverts that present sufferers working, bicycling, even enjoying basketball after the process, mentioned Dr. Nicholas DiNubile, a Havertown, Pa., orthopedic surgeon specializing in sports activities drugs. While many individuals with synthetic knees can return to reasonable train — comparable to doubles tennis — it’s unrealistic to think about them enjoying full-court basketball once more, he mentioned.
“Hospitals are all competing with each other,” DiNubile mentioned. Marketing can mislead youthful sufferers into pondering, “‘I’ll get a new joint and go back to doing everything I did before,’” he mentioned. To Rickert, “medical advertising is a big part of the problem. Its purpose is to sell patients on the procedures.”
Rickert mentioned that some sufferers are supplied surgical procedure they don’t want and that cash generally is a issue.
Knee replacements, which price $31,000 on common, are “really crucial to the financial health of hospitals and doctors’ practices,” he mentioned. “The doctor earns a lot more if they do the surgery.”
Ignoring Alternatives
Yet surgical procedure isn’t the one option to deal with arthritis.
Patients with early illness usually profit from over-the-counter ache relievers, dietary recommendation, bodily remedy and training about their situation, mentioned Daniel Riddle, a bodily remedy researcher and professor at Virginia Commonwealth University in Richmond.
Studies present that these approaches may even assist folks with extra extreme arthritis.
In a study printed in Osteoarthritis and Cartilage in April, researchers in contrast surgical and non-surgical remedies in 100 older sufferers eligible for knee substitute.
Over two years, all the sufferers improved, whether or not they have been supplied surgical procedure or a mix of non-surgical therapies. Patients randomly assigned to endure instant knee substitute did higher, enhancing twice as a lot as these given mixture remedy, as measured on commonplace medical exams of ache and functioning.
But surgical procedure additionally carried dangers. Surgical sufferers developed 4 occasions as many issues, together with infections, blood clots or knee stiffness extreme sufficient to require one other medical process beneath anesthesia. In common, 1 in every 100 to 200 patients who endure a knee substitute die inside 90 days of surgical procedure.
Significantly, most of these handled with non-surgical therapies have been glad with their progress. Although all have been eligible to have knee substitute later, two-thirds selected to not do it.
Tia Floyd Williams suffered from painful arthritis for 15 years earlier than having a knee changed in September 2017. Although the process appeared to go easily, her ache returned after about 4 months, spreading to her hips and decrease again.
She was advised she wanted a second, extra in depth surgical procedure to place a rod in her decrease leg, mentioned Williams, 52, of Nashville.
“At this point, I thought I would be getting a second knee done, not redoing the first one,” Williams mentioned.
Other sufferers, comparable to Ellen Stutts, are pleased with their outcomes. Stutts, in Durham, N.C., had one knee changed in 2016 and the opposite changed this 12 months. “It’s definitely better than before the surgery,” Stutts mentioned.
Making Informed Decisions
Doctors and economists are more and more involved about inappropriate joint surgical procedure of all sorts, not simply knees.
Inappropriate remedy doesn’t hurt solely sufferers; it harms the well being care system by elevating prices for everybody, mentioned Dr. John Mafi, an assistant professor of medication on the David Geffen School of Medicine at UCLA.
The 723,000 knee replacements carried out in 2014 price sufferers, insurers and taxpayers greater than $40 billion. Those prices are projected to surge because the nation ages and grapples with the results of the weight problems epidemic, and an getting old inhabitants.
To keep away from inappropriate joint replacements, some well being programs are growing “decision aids,” easy-to-understand written materials and videos in regards to the dangers, advantages and limits of surgical procedure to assist sufferers make extra knowledgeable decisions.
In 2009, Group Health launched resolution aids for sufferers contemplating joint substitute for hips and knees.
Blue Shield of California applied an identical “shared decision-making” initiative.
Executives on the well being plan have been particularly involved in regards to the massive improve in youthful sufferers present process knee substitute surgical procedure, mentioned Henry Garlich, director of well being care worth options and enhanced medical packages.
The share of knee replacements carried out on folks 45 to 64 elevated from 30 p.c in 2000 to 40 p.c in 2015, in response to the Agency for Healthcare Research and Quality.
Because the units can put on out in as little as a number of years, a youthful individual might outlive their knees and require a substitute, Garlich mentioned. But “revision” surgical procedures are rather more difficult procedures, with a better threat of issues and failure.
“Patients think after they have a knee replacement, they will be competing in the Olympics,” Garlich mentioned.
Danette Lake as soon as deliberate to endure knee substitute surgical procedure on her different knee. Today, she’s undecided what to do. She is afraid of being disillusioned by a second surgical procedure.
Sometimes, she mentioned, “I think, ‘I might as well just stay in pain.’”
