Therapeutic Review of Methylprednisolone Acetate Intra ‐Articular Injection in the Management of Osteoarthritis of the Knee – Part 1: Clinical Effectiveness

Abstract Intra‐articular (IA) corticosteroid injections are a common approach in the management of osteoarthritis (OA) of the knee. The effectiveness of injections and particular injection products is often discussed and debated in clinical arenas. The following therapeutic review examines the evidence for intra‐articular methylprednisolone acetate (MPA) injections in the management of OA knee. A review of research evidence, published guidelines and clinical literature was undertaken following an electronic database and relevant literature search. The review found that there is limited evidence which indicates that a single dose intra‐articular MPA injection can provide short to medium term benefits for pain, with less evidence for beneficial effects on function or stiffness. There is heterogeneity across studies and until recently, most studies had only short to medium term follow‐up periods, thus limiting the evidence available on longer term benefit. There was also evidence indicating equivalent overall efficacy of MPA to that of other corticosteroid products. Most guideline recommendations concerning IA injections for OA knee have drawn on evidence from pooled data for several corticosteroid products. The review also found there was limited reporting of the incidence of adverse events in most studies. Overall, MPA shows efficacy for symptom relief in OA knee. At an individual management level, evidence for a limited duration of effect needs consideration in inject...
