Arthroplasty News and Research RSS Feed - Arthroplasty News and Research

Arthroplasty is a orthopaedic surgery procedure, in which the arthritic or dysfunctional joint surface is replaced with something better or by remodeling or realigning the joint by osteotomy or some other procedure. Previously, a popular form of arthroplasty was interpositional arthroplasty with interposition of some other tissue like skin, muscle or tendon to keep inflammatory surfaces apart or excisional arthroplasty in which the joint surface and bone was removed leaving scar tissue to fill in the gap. Other forms of arthroplasty include resection(al) arthroplasty, resurfacing arthroplasty, mold arthroplasty, cup arthroplasty, silicone replacement arthroplasty, etc. Osteotomy to restore or modify joint congruity is also an arthroplasty.

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 identifies correlation between miRNAs and osteoarthritis

Study identifies correlation between miRNAs and osteoarthritis

The results of a study presented today at the European League Against Rheumatism Annual Congress identify a correlation between the presence of biomarkers in the blood, known as micro RNAs (miRNAs), and the development of severe osteoarthritis (OA) of the knee or hip joint. The findings suggest that miRNAs may be used as biomarkers to predict severe OA disease in individuals. [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]
Study finds higher readmission rates for same-day total joint replacement surgery

Study finds higher readmission rates for same-day total joint replacement surgery

As the effectiveness of anesthesia, pain management and rehabilitation continues to improve, more orthopaedic procedures are being done on an outpatient basis. In a new research study presented today at the 2014 Annual Meeting of the American Academy of Orthopaedic Surgeons, same-day total joint replacement (TJR) patient outcomes were comparable to those of patients admitted to the hospital and staying at least one night following surgery.

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.

Patients should wait at least six weeks to resume driving following shoulder replacement surgery

Patients should wait at least six weeks to resume driving following shoulder replacement surgery

More than 53,000 Americans have total shoulder joint replacement (SJR) surgery each year, and yet the effects of this surgery on a patient's ability to safely drive a vehicle, and the appropriate recovery time before patients should return to driving, have yet to be determined. [More]
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.

Research roundup: Examining readmissions; easing doctor burnout

Research roundup: Examining readmissions; easing doctor burnout

Despite massive early IT problems, exchange enrollment is accelerating rapidly. While enrollment may not reach 7 million by the end of March, we expect at least 5 million to have enrolled by the close of the initial open-enrollment period. If enrollment falls far short, HHS could extend open enrollment for a fixed period to reach its 7 million target. ... We project that 5 million new beneficiaries will be covered by Medicaid and the Children's Health Insurance Program by the end of 2014. Medicaid managed-care enrollment of non-dual beneficiaries will increase by 20 percent from 2013 to 2014 and by 38 percent from 2013 to 2016. We expect that 75 percent of non-dual Medicaid beneficiaries will be covered by Managed Care Organizations starting in 2015, up from 63 percent in 2012 (Feb. 2014). [More]
