Efficacy of intra-articular polynucleotides associated with hyaluronic acid vs hyaluronic acid alone in the treatment of knee osteoarthritis: A systematic review and meta-analysis of randomized clinical trial.

Background: The reduced range of motion and pain are the most characteristic clinical features of osteoarthritis (OA). Hyaluronic acid (HA), which is one of the infiltrative therapies for OA treatment, and polynucleotides (PNs), which is a DNA-derived macromolecule favored cell growth and collagen production, are an ongoing debate in clinical effectiveness.

Methods: We plan to perform a systematic review and meta-analysis of randomized clinical trial to evaluate efficacy of intra-articular polynucleotides associated with hyaluronic acid versus hyaluronic acid alone in the treatment of knee osteoarthritis.

A randomized controlled study for Yuanhu Zhitong dropping pills in the treatment of knee osteoarthritis.

Background: Knee osteoarthritis (KOA) is a common chronic disorder of knee and the leading cause of pain in the elderly with an overall prevalence of 50% in people over 60 years of age. This disease is an important factor affecting the quality of life of middle-aged and elderly people, and its main symptom is knee joint pain. Due to the pain, the knee joint activity function is limited, bringing great pain to patients, affecting their quality of life, effective prevention, and treatment of KOA is a modern medical problem.

Zoledronic acid ameliorates the effects of secondary osteoporosis in rheumatoid arthritis patients.

Background: Secondary osteoporosis may occur in patients with rheumatoid arthritis (RA), causing irreversible joint damage and disability. Bisphosphonates, the recently developed bone resorption inhibitors, have demonstrated significant therapeutic effects on senile and postmenopausal osteoporosis. This study evaluated the efficacy and safety of zoledronic acid (ZOL), with or without methotrexate (MTX), for the prevention and treatment of bone destruction in RA patients.
