Low-income patients may report good outcomes after knee replacement

An analysis recently published in the journal Arthritis and rheumatism revealed that, depending on the form of arthritis people have, they may be more likely to experience complications after total joint replacement (TJR) surgeries. Although the chances that they will develop adverse effects are low, individuals who undergo TJR may experience infection, dislocation of new joints, the need to replace an artificial joint, blood clots and death, Arthritis Today reported.

The researchers looked at the data from 40 previous studies on TJRs, published between 1990 and 2011. They found that patients with rheumatoid arthritis (RA) were more likely to develop an infection after a knee replacement than individuals with osteoarthritis.

Study co-author Bheeshma Ravi, M.D., suggested that the reason that one group of arthritis patients may be more at risk for infection than the other is because RA patients are usually treated with medications that regulate the immune system, limiting its ability attack the body, which is what happens in affected individuals. However, it subsequently makes people with RA more susceptible to infection after undergoing surgery, News-medical.Net reported.
