Most people who undergo a knee joint replacement have either osteoarthritis, the wear-and-tear blazon of arthritis; rheumatoid arthritis, an autoimmune condition that causes joint pain and damage; or post-injury arthritis.
"Osteoarthritis, rheumatoid arthritis and posttraumatic arthritis touch on the genu through different mechanisms, however, these unlike atmospheric condition are like in that they all result in loss of cartilage, which causes pain and loss of motion," says Nathanael Heckmann, Physician, an orthopaedic surgeon at Keck Medicine of USC and an banana professor of clinical orthopaedic surgery at the Keck School of Medicine of USC. "When these symptoms go severe, knee joint replacement surgery may provide considerable symptom relief past replacing the worn-out surfaces of the genu."
two. Nonsurgical treatments are no longer effective
If yous have arthritis of the genu, you'll probably start with more than bourgeois measures such as medications, steroid injections or physical therapy to alleviate your symptoms. But at some point, they may not be enough.
"Anti-inflammatories, injections and physical therapy are temporary measures to provide hurting relief, but they don't reverse the underlying cause of pain and don't allow cartilage to regenerate," Heckmann says. "As time passes, these arthritic conditions tend to progress in severity, rendering these types of treatments less and less effective."
At that indicate, surgery may exist an pick.
3. Your pain prevents y'all from doing normal activities or caring for yourself
If you tin can't become relief from other treatments, your knee pain may offset interfering with your daily life.
"In general, the timing of a total articulatio genus replacement is determined by the impact the knee is having on your quality of life," says Jay Lieberman, MD, principal of orthopaedic surgery at Keck Medicine and chair and professor of orthopaedic surgery at the Keck School. "If conservative treatments are non working and you take significant pain while walking, you may be a good candidate for surgery."
iv. You have severe hurting even when resting, and you can't slumber
Co-ordinate to Lieberman, pain while at rest that isn't responding to other measures may make you lot a good candidate likewise.
"In addition, if y'all too have consistent hurting at night, this tin be quite debilitating," Lieberman says.
5. Your knee is always bloated
Swelling is another sign your knee is not responding to other treatments.
"A human knee that is consistently swollen despite the use of anti-inflammatory medications, steroid injections and concrete therapy suggests degeneration of the cartilage and/or instability of the knee, which can be confirmed with an Ten-ray," Lieberman explains. This can make you a candidate for a total knee replacement, he says.
vi. Your human knee has become deformed
If your arthritis is advanced, it tin can affect the way you walk, which can likewise lead to further problems elsewhere in your torso.
"As arthritis progresses, the knee may become bowed or 'knock-kneed,'" Heckmann says. "If this blazon of deformity develops over time, a knee replacement may be indicated."
In improver, people with arthritis may as well lose the ability to straighten their knee, according to Heckmann. "If this occurs, you should seek an evaluation with an orthopaedic surgeon, as this loss of motion may be permanent, even after the knee has been replaced," he adds.
7. You're OK with fugitive certain activities afterward
Patients should know what to expect subsequently knee replacement surgery and understand that regular high-impact activities may not be advisable.
"Total knee replacement is quite successful in enabling patients to return to an active lifestyle — patients can perform all types of recreational activities, including hiking, bicycling, skiing, surfing, tennis and golf," Lieberman says. "In general, we do non limit activities but suggest that patients avert bear on activities on a consistent ground to reduce wear of the prosthesis."
8. Y'all're of a certain age
Human knee replacement is generally done in older people over sixty, in part because younger people'southward more than active lifestyles may put besides much stress on the artificial human knee, causing it not to last as long; 2nd replacement surgeries may not exist as successful.
