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.
Modified classification system finds over one-third of knee replacements as inappropriate

Modified classification system finds over one-third of knee replacements as inappropriate

New research reports that more than one third of total knee replacements in the U.S. were classified as "inappropriate" using a patient classification system developed and validated in Spain. The study, published in Arthritis & Rheumatology, a journal of the American College of Rheumatology (ACR), highlights the need for consensus on patient selection criteria among U.S. medical professionals treating those with the potential need of knee replacement surgery.

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

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.
