Knee Arthroplasty News and Research RSS Feed - Knee Arthroplasty News and Research

Knee arthroplasty or knee replacement surgery has developed to its present advanced stage over the last few decades. This is mainly due to technical advances and better understanding of knee pathophysiology and functions.

P4 pain scale found suitable for use in knee osteoarthritis

The P4 pain scale compares favorably with other commonly used measures for patients with severe knee osteoarthritis, a Canadian study has found. [More]
Study finds that patients who lose weight have better joint replacement outcomes

Study finds that patients who lose weight have better joint replacement outcomes

While many overweight patients have the best intentions to lose weight after joint replacement, a study at Hospital for Special Surgery (HSS) finds that although some are able to achieve this goal, equal numbers of patients actually gain weight after hip or knee replacement. [More]
Bariatric surgery may reduce knee pain in elevated BMI patients

Bariatric surgery may reduce knee pain in elevated BMI patients

​There is a known link between elevated body mass index (BMI) and symptomatic knee osteoarthritis (OA). While patients who have undergone gastric bypass surgery (GBS)-a procedure that closes off much of the stomach and causes food to bypass a portion of the small intestine─typically lose weight, the comparative impact of this weight loss on knee pain and function has not been measured.

Optimizing patient health before total knee replacement surgery may reduce need for revisions

The number of total knee replacement (TKR) procedures continues to climb, as does the number of revision total knee replacement (RTKR) surgeries. In the study, "The Epidemiology of Revision Total Knee Arthroplasty in the United States," presented today at the 2014 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), researchers used the Nationwide Inpatient Sample (NIS) to evaluate the cause of knee failure for 301,718 revision RTKR surgeries performed between 2005 and 2010.

Comprehensive approach to the evaluation of groin pain

Comprehensive approach to the evaluation of groin pain

She wasn't born this way, but even Lady Gaga experienced groin pain-typically a symptom of hip disease such as arthritis of the hip-or, in her case, a hip labral tear. Groin pain is a common health complaint. According to a literature review appearing in the September 2013 issue of the Journal of the American Academy of Orthopaedic Surgeons, one in four people develop hip arthritis-damage to the surfaces in the hip joint-before the age of 85 that contributes to groin pain.

Choosing Wisely List released by The American Academy of Orthopaedic Surgeons

Choosing Wisely List released by The American Academy of Orthopaedic Surgeons

The American Academy of Orthopaedic Surgeons (AAOS) today released a list of specific tests or procedures that are commonly ordered but not always necessary in orthopaedics as part of the Choosing Wisely- campaign, an initiative of the ABIM Foundation. The list identifies five targeted, evidence-based recommendations that can support conversations between patients and physicians about what care is really necessary. [More]

Epidural steroid injection is associated with increased spinal fracture

Most aging adults will experience back pain or a spinal disorder at some time in their life. In fact, about 25.8 million visits were made to physicians' offices due to primary back problems. Treatment focuses on pain relief and is available in both non-surgical (medication or physical therapy) and surgical forms. [More]

Lower-income individuals are more likely to report dissatisfaction with knee replacement surgery

Knee replacement surgery is a very common procedure. However, it does not always resolve function or pain in all the recipients of new knees. [More]

GE Healthcare introduces novel MR imaging technology

At an event held today at Hospital for Special Surgery, GE Healthcare introduced MAVRIC SL, a novel magnetic resonance imaging technique designed to address the growing clinical need to more accurately image soft tissue and bone in patients with MR Conditional-labeled implants, such as joint replacements and other instrumentation.

Obesity may not diminish outcomes or increase risk of complications in total knee replacement patients

Obesity may not diminish outcomes or increase risk of complications in total knee replacement patients

Obesity alone may not diminish outcomes or increase the risk of complications in total knee replacement (TKR) patients, according to two research studies presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS). However, TKR replacement patients may face significantly longer hospital stays and related costs. [More]
Study: Total knee replacements in younger patients with juvenile arthritis last for 10 years

Study: Total knee replacements in younger patients with juvenile arthritis last for 10 years

When you think of knee replacement surgery, you generally envision an older adult with painful arthritis. But the procedure is also used for younger patients with juvenile idiopathic arthritis whose joints have been severely damaged by the disease. Because the surgery in younger patients is relatively rare, little data exist on the longevity of knee replacements in JIA patients. [More]
