For most people, knee replacement provides pain relief, improved mobility and a better quality of life. Most knee replacements can be expected to last at least 15 to 20 years. After recovery, you can engage in various low-impact activities, such as walking, swimming, golfing or biking.
Usually by the 6 month mark, you're about 90% recovered. 30 out of 100 patients at 6 months will say “My knee feels pretty normal like the other side,” while the other 70 will say, “It's still not quite a normal knee but it's substantially better than what I had before.”
After knee replacement surgery, you can gradually resume normal activities and there are no permanent restrictions, as long as you stay within your comfort level and follow the guidance of your healthcare team.
You shouldn't downhill ski or play contact sports such as football and soccer. In general, avoid sports that require jerking, twisting, pulling, or running. You should be able to do lower-impact activities, such as hiking, gardening, swimming, playing tennis, and golfing.
In most cases, patients can walk without help from assistive devices like crutches or a walker within six weeks after knee replacement surgery. That said, physical therapy continues after this time to help your knee and the surrounding muscles grow stronger and more flexible.
A recent study found that 20% of people are unhappy with their knee replacements. Here's what can play into that dissatisfaction. Let's get one thing straight right away — knee replacements are often a smart choice. A lot of people have less knee pain and more mobility after their surgery and rehab.
The 0.3% regret rate of our newest study is much smaller compared to other, common yet serious surgeries. Interestingly, knee replacement surgery has a dissatisfactory rate of 6-30%.
Overall, patient satisfaction after primary total knee arthroplasty was 81% in our study.
Mortality still low up to 10 years after TKA
As anticipated, the study found that overall mortality rates following TKA are low globally, regardless of the amount of postoperative time. The pooled 30-day, 90-day, one-year, five-year and 10-year rates were 0.14%, 0.35%, 1.1%, 5.38% and 10.18%, respectively.
Recovery is slow
While it's different for everyone and depends on the type of knee surgery you've had, many people are surprised by how long it takes to recover. The time it takes to start doing simple tasks around the home, get back to work and importantly bending your new and improved knee may catch you by surprise.
Even though you will be able to resume most activities, you may want to avoid doing things that place excessive stress on your "new" knee, such as participating in high-impact activities like jumping, jogging, or skiing.
Your body just went through a major surgery and needs time to heal. Most people can resume daily activities with reduced pain approximately three to six weeks after surgery. Full recovery can take anywhere from four months to a year.
The biggest challenge in the early recovery of a TKR (up to 3 months postoperative) is the regaining of knee motion.
Your knee will still have some soreness, but it is very tolerable. You may get tired if you are on your feet for long periods of time, but strength can continue to improve with time. This is still some swelling in the knee, but it is usually better than before surgery.
Most people have much less pain after knee replacement surgery and are able to return to many of their activities. But as with any surgery, there are some risks, including: Lack of good range of motion. After surgery, some people can't bend their knee far enough to do their daily activities, even after several weeks.
You may be offered knee replacement surgery if: you have severe pain, swelling and stiffness in your knee joint and your mobility is reduced. your knee pain is so severe that it interferes with your quality of life and sleep. everyday tasks, such as shopping or getting out of the bath, are difficult or impossible.
The surgery itself depends on the type of knee operation. A total knee replacement, for example, will likely take between 2-3 hours. Whereas a partial knee replacement normally takes around an hour. Most knee surgeries take between 1-3 hours.
However, total knee replacement does not restore the ease associated with normal knee function. Research shows that people climb stairs slower after knee replacement; they also have a reduction in muscle strength around the knee and complete less total knee work.
TKA patients begin rehabilitation during the seven-day bedrest period, with the goals of decreasing swelling, increasing ROM, promoting normal leg control and promoting normal gait with an assistive device.
Genetics notwithstanding, Sheth said there are some factors that can potentially stave off a knee replacement. Keeping body weight down eases the impact on the knee. And when exercising, Sheth said avoiding activities that cause pounding or other possible trauma to the knee can better preserve cartilage.
Crossing your legs
Shortly after your total knee replacement, it is not recommended that you cross your legs. This is most likely due to the lack of range in your knee to be able to cross your legs. If you have ever seen someone sitting cross legged, you know how much their knee needs to bend.
Most patients, even if they live alone, can safely go directly home from the hospital after hip or knee replacement surgery, according to a recent study.
