A topical diclofenac sodium solution has been shown to effectively treat symptoms of primary OA of the knee, improving pain and physical function by 45.7% and 36.7%, respectively. The study found that this treatment had a superior efficacy compared to a control solution, with minimal adverse effects related to skin reactions.
Patients with knee osteoarthritis prioritize treatment characteristics, such as risk of common adverse side effects and cost, when choosing medication. Non-selective NSAIDs are the least preferred option due to their limited impact on patient preferences.
A multicenter study found that the maximum daily OTC dose of acetaminophen (4000mg) was as effective as prescription doses of naproxen (750mg) for osteoarthritis pain relief. The study involved 551 patients with mild-to-moderate OA and showed no significant differences in efficacy between the two treatments over a six-month period.

A new clinical syndrome has been discovered that leads to severe osteoarthritis, characterized by cartilage breakdown and the presence of specific FRZB gene mutations. The study sheds light on the genetic mechanisms underlying this complex disease, with potential implications for treatment and prevention.
A new study demonstrates that adding menthol to a topical cream containing cetylated fatty acids significantly reduces pain and improves functional performance in patients with knee, elbow, and wrist osteoarthritis. The treatment also shows promise for upper-extremity performance and pain relief in these individuals.

A new study by Duke University Medical Center researchers found that C-reactive protein levels are not a reliable indicator of osteoarthritis due to their strong correlation with body mass index (BMI) and ethnicity. Instead, these proteins can serve as an indicator of a patient's response to therapy for osteoarthritis.
A new study suggests radiosynoviorthesis is effective in treating osteoarthritis, providing significant pain relief to 2/3 of patients with proven synovitis. The procedure, which involves removing inflamed membrane using beta-emitting radionuclides, shows promise as a treatment option for OA.
A study published in Arthritis & Rheumatism reveals that cartilage oligometic matrix protein (COMP) is present in blacks, with average levels higher in patients and men than in whites. COMP may serve as a biomarker for osteoarthritis progression.
Researchers at Rice University are working on growing replacement cartilage for the meniscus, a kidney-shaped wedge of cartilage that cushions stress in the knee joint. By developing methods to simulate mechanical conditions and grow tissue in precise shapes, they aim to create more effective treatments for osteoarthritis.
Dogs on a reduced-calorie diet lived up to 13 years, while those with high-calorie diets averaged 11.2 years. The study also found that lean body conformation and dietary restriction can help prevent chronic illnesses like osteoarthritis.
A new study found that the increased pain following exercise in osteoarthritis patients is short-lived, typically subsiding by evening. This insight can help patients cope with temporary increases in pain and stick to exercise programs for long-term benefits.
The Osteoarthritis Initiative will recruit 5,000 participants aged 50+ at high risk for knee osteoarthritis. The project aims to establish a natural history database for osteoarthritis, allowing researchers to identify potential new disease targets and develop tools for understanding disease progression.
A recent study has identified eight chromosomal sites that may harbor genes for hand OA, with the strongest evidence found on chromosomes 7p and 11q. The research used a genome scan of Framingham participants and their offspring to investigate genetic linkages.
Researchers have developed a new x-ray technique called diffraction enhanced imaging (DEI) that can image cartilage and detect early stages of osteoarthritis. This technology has the potential to improve diagnosis and treatment of the disease, which affects over half of the nation's elderly.
Researchers found that a specific mutation in collagen II affects the interaction with another collagen, leading to cartilage damage and osteoarthritis progression. The study's results provide insight into how mutations in collagen genes contribute to the disease.
A new UNC research project aims to investigate the connection between osteoarthritis, emotional responses, and coping strategies. The two-year study will analyze data from over 20,000 participants to identify predictors and consequences of emotional distress in people with arthritis.
Dr. Waddell presents two studies showing viscosupplementation is safe and effective for patients with advanced osteoarthritis, delaying total knee replacements by up to 1 year.
A 250-participant study found that exercise programs reduced the risk of disability in older adults with knee osteoarthritis. The results suggest that physical exercise can play a crucial role in maintaining independence and reducing disabilities as people age.
A small study found leech therapy to be effective in reducing pain from osteoarthritis, with rapid relief seen after three days and sustained effects four weeks later. The treatment produced no side effects or infections.
A public-private partnership has been launched to combat osteoarthritis, a chronic disease affecting millions of Americans. The Osteoarthritis Initiative will provide critical funding and resources for clinical research centers to establish natural history databases and biospecimen repositories.
A new study finds that black men are 33% more likely to develop hip osteoarthritis than white men, while black women are twice as likely to develop the condition. Weight disparities account for comparable differences in women.
Researchers discovered that COMP significantly increases in the blood of people with hip or knee osteoarthritis even before X-rays reveal joint damage. Elevated levels of COMP correspond strongly with reports of joint pain and may indicate an early stage of osteoarthritis.
A comprehensive program involving exercise, weight loss, and joint protection principles is necessary for effective osteoarthritis management. Over-the-counter acetaminophen may be the only required medication for mild-to-moderate pain relief.
This issue of Annals of Internal Medicine offers guidance on identifying and treating depression in terminally ill patients. A new program combining physical therapy and exercise is shown to effectively manage osteoarthritis symptoms, potentially delaying surgery for affected adults. Meanwhile, a pet parrot infection has been transmitt...
