Knee replacement is generally done in older people over 60, in part because younger people's more active lifestyles may put too much stress on the artificial knee, causing it not to last as long; second replacement surgeries may not be as successful.
The most common reason for knee replacement surgery is osteoarthritis. Other conditions that cause knee damage include: rheumatoid arthritis. haemophilia.
The most common reason for knee replacement surgery is to ease pain caused by arthritis. People who need knee replacement surgery usually have problems walking, climbing stairs and getting up out of chairs. If only one part of the knee is damaged, surgeons often can replace just that part.
Knee replacement has traditionally been reserved for the older population. Currently, the average age of a patient who gets knee replacement surgery in the United States is around 65 years old. Generally, surgeons consider anyone under age 50 to be young for knee replacement.
As knee arthritis progresses, the knee becomes much looser and more unstable. In some cases, this is mild. In other cases, it is substantial enough that cause the patient to fall. Patients who have bone-on-bone arthritis and are starting to fall because of it should strongly consider surgery.
When quantifying how much pain there is after surgery, it is relative to the patient. The pain after a knee replacement is typically no worse than one of your worst days before you had surgery. However, you can feel this way for the first two to three weeks after the day of surgery.
Age alone is no bar to surgery. Older and younger people benefit equally, as long as they are generally healthy to start. However, people under 60 are encouraged to delay total knee replacement if they can.
Simply put, the longer you wait to get a knee replacement, the more wear and tear you put on your knees – and the longer you live with increasing pain, stiffness or mobility issues. But there are a few other things to consider, including: As your knee condition worsens, your quality of life can also decrease.

The downside of knee replacement is that a small number of patients may experience surgical complications, including infection, blood clots, heart or lung risks, which in a small number of patients can be fatal.
There is a range of accepted weight ranges, but the current standard is that anyone obese (greater than 100 pounds over ideal weight or a BMI of roughly 40-45) should not consider joint replacement.
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.
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.
Total knee arthroplasty (TKA) is a common and effective procedure that is expected to be performed in increasing numbers in the future [1, 2]. Previous studies have shown 6–30% of patients are dissatisfied after the surgery, both in the presence and in the absence of postoperative complications [3–12].
Effectiveness of total knee replacement
Many studies show that 90-95 percent of total knee replacements are still functioning well 10 years after surgery.
The majority of patients expect to be able to kneel after TKR,2,4,5 however, these expectations are frequently not met,1,6 with between 50% and 80% of patients reporting that they have difficulty kneeling or do not kneel in the months and years after TKR.

In a healthy joint cartilage aids in the congruency of movement of the joint between the two bones. Thus if someone has a joint which is “Bone on Bone” it suggests the amount of cartilage on the bones in the joint is reduced and inflammation present. Some research has found a correlation between knee pain and OA.
Many patients ask this question when considering TKR and the consensus is that the spring and early fall are the best seasons. You'll want to wear as little clothing as possible during your recovery because it makes cleaning the wound and moving around easier.
The good news is that knee replacement surgery is generally considered a safe procedure. Complications are very rare.
