摘要
Osteoarthritis(OA)poses a substantial burden on patients,leading to pain,functional decline,and reduced quality of life.While conventional treatments focus on symptom management,disease-modifying interventions are yet to be established.This review explores the efficacy of intra-articular interventions,particularly hyaluronic acid(HA),mesenchymal stem cells(MSCs),and platelet-rich plasma(PRP),in the context of OA management.HA injections,with diverse formulations like Hylan G-F20,sodium hyaluronate,and hyaluronan,present varying outcomes,necessitating a nuanced understanding of their effectiveness and timing.MSC therapy,derived from adipose tissue,umbilical cord,or bone marrow,shows promising results in clinical improvement,with adipose-derived MSCs demonstrating efficacy in maintaining benefits over 6 mo.Conversely,bone-marrow-derived MSCs show limited effectiveness,highlighting the need for sourcespecific considerations.PRP has emerged as a superior option for long-term pain reduction and quality of life improvement,with leukocyte-poor formulations and a critical platelet count of 10 billion demonstrating optimal results.This comprehensive analysis underscores the potential of intra-articular interventions in OA management,emphasizing the need for personalized and evidence-based approaches to enhance treatment efficacy and patient outcomes.
