Results published in Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR), show that long term use of the mobility shoes helped OA patients adapt their gait, or how they walk, which improved knee loading, even when the mobility shoes were no longer worn. http://medicalxpress.com/news/2013-04-mobility-knee-osteoarthritis.html Arthritis & Rheumatism Wed, 10 Apr 2013 00:00:01 EST news284754361 Many middle age and older adults have disabling knee pain due to a tear in the meniscus, an important supporting structure in the knee that is often damaged in patients with underlying knee osteoarthritis. In the United States, more than 450,000 arthroscopic meniscal surgeries are performed each year to treat meniscal tears. However, there is little data available to clinicians who must decide with their patients whether it is best to treat tears with surgery or with physical therapy. Now, new research from Brigham and Women's Hospital (BWH), suggests that physical therapy (PT) may prove just as effective as surgery for some patients. These findings are presented at the annual meeting of the American Academy of Orthopedic Surgeons and simultaneously published online in the New England Journal of Medicine. http://medicalxpress.com/news/2013-03-surgery-option-meniscal-osteoarthritis.html Diseases, Conditions, Syndromes Tue, 19 Mar 2013 04:50:01 EST news282886586 (HealthDay)—For patients with symptomatic knee osteoarthritis (OA), a single-item measure of self-rated health can be used to predict mental and social health outcomes, according to a study published in the February issue of Arthritis Care & Research. http://medicalxpress.com/news/2013-02-self-rated-health-outcomes-knee-oa.html Arthritis & Rheumatism Fri, 15 Feb 2013 15:10:04 EST news280159667 A study by researchers from Hospital for Special Surgery has shown that platelet-rich plasma (PRP) holds great promise for treating patients with knee osteoarthritis. The treatment improved pain and function, and in up to 73% of patients, appeared to delay the progression of osteoarthritis, which is a progressive disease. The study appears online, ahead of print, in the Clinical Journal of Sports Medicine. http://medicalxpress.com/news/2013-02-platelet-rich-plasma-treatment-potential-knee.html Diseases, Conditions, Syndromes Wed, 13 Feb 2013 10:00:04 EST news279971384 Osteoarthritis is a progressive joint disease that affects approximately one third of individuals age 65 and older. The disorder causes gradual loss of joint cartilage and bony degeneration while simultaneously creating new bone formation, or bone spurs. The end result of this cascade is joint stiffness, loss of motion and pain. In addition, some individuals also experience irritation of the joint lining, synovitis, which causes painful accumulation of excess joint fluid. http://medicalxpress.com/news/2013-02-nonsurgical-treatment-osteoarthritis-discussed.html Diseases, Conditions, Syndromes Tue, 05 Feb 2013 06:54:10 EST news279269643 (HealthDay)—Overweight African-American women with or at risk of knee osteoarthritis are at higher risk than overweight white women of poor functional outcomes, according to a study published in the January issue of Arthritis Care & Research. http://medicalxpress.com/news/2013-01-poor-arthritis-outcome-overweight-black.html Arthritis & Rheumatism Wed, 23 Jan 2013 16:00:01 EST news278177014 In a two year randomized trial, patients with symptomatic knee osteoarthritis who received vitamin D supplementation did not have a significant difference in knee pain or cartilage volume loss compared to patients who received placebo, according to a study appearing in the January 9 issue of JAMA. http://medicalxpress.com/news/2013-01-vitamin-d-supplementation-knee-pain.html Arthritis & Rheumatism Tue, 08 Jan 2013 16:00:07 EST news276874598 Both very high and very low levels of physical activity can accelerate the degeneration of knee cartilage in middle-aged adults, according to a new study presented at the annual meeting of the Radiological Society of North America (RSNA). http://medicalxpress.com/news/2012-11-bad-knees.html Health Mon, 26 Nov 2012 00:00:01 EST news273068517 (HealthDay)—The osteoporosis therapeutic strontium ranelate (SrRan) reduces radiographic and radiological progression of knee osteoarthritis, according to a study presented at the annual meeting of the American College of Rheumatology, held from Nov. 10 to 14 in Washington, D.C. http://medicalxpress.com/news/2012-11-acr-strontium-ranelate-knee-oa.html Arthritis & Rheumatism Mon, 12 Nov 2012 18:00:02 EST news271960458 (HealthDay)—Only a few physical therapy (PT) interventions are effective for knee pain secondary to osteoarthritis, specifically exercise and ultrasonography, according to a review published in the Nov. 6 issue of the Annals of Internal Medicine. http://medicalxpress.com/news/2012-11-pt-interventions-effective-knee-osteoarthritis.html Arthritis & Rheumatism Tue, 06 Nov 2012 16:17:42 EST news271441055 (HealthDay)—For patients with knee osteoarthritis, self-reported knee instability and fear of physical activity correlate with the likelihood of treatment response following a therapeutic exercise program, according to a study published in the November issue of Arthritis Care & Research. http://medicalxpress.com/news/2012-11-factors-impacting-benefit-knee-oa.html Arthritis & Rheumatism Fri, 02 Nov 2012 12:39:48 EST news271078771 (HealthDay)—For patients with knee osteoarthritis (K-OA), the lack of correlation between clinical pain and radiographic evidence of disease severity may be due to central sensitization, according to a study published online Sept. 7 in Arthritis & Rheumatism. http://medicalxpress.com/news/2012-09-pain-abnormalities-knee-oa.html Arthritis & Rheumatism Mon, 17 Sep 2012 14:10:01 EST news267105564 A study conducted by researchers at Boston University School of Medicine (BUSM) shows that magnetic resonance imaging (MRI) detected a high prevalence of abnormalities associated with knee osteoarthritis in middle-aged and elderly patients that had no evidence of knee osteoarthritis in X-ray images. http://medicalxpress.com/news/2012-08-mri-osteoarthritis.html Diseases, Conditions, Syndromes Fri, 31 Aug 2012 11:46:04 EST news265632344 Canadian researchers have determined that community-based pharmacists could provide an added resource in identifying knee osteoarthritis (OA). The study, published in Arthritis Care & Research, a journal of the American College of Rheumatology (ACR), represents the first evidence supporting a collaborative approach to managing knee OA.
