Abstract
BACKGROUND: As the ultimate method for the treatment of osteoarthritis, total knee arthroplasty (TKA) has been widely used in the clinic. Local injection of multimodal cocktails, including corticosteroids, is commonly used for pain management after TKA. This meta-analysis aims to systematically evaluate the effect of periarticular injection of corticosteroids on postoperative pain relief and knee functional recovery in patients undergoing TKA. METHODS: PubMed, Cochrane Library, EMBASE, and Web of Science databases were comprehensively searched for all randomized controlled trials (RCTs) published before July 1, 2020, that investigated the efficacy of corticosteroids for TKA. RESULTS: Ten RCTs involving a total of 829 patients were assessed in the meta-analysis. Compared with the control group, the visual analogue scale (VAS) score at rest of the corticosteroid group decreased significantly at postoperative day 1 (POD1), POD2, and POD3 (p < 0.05). Besides, the range of flexion motion of the knee joint in the corticosteroid group at POD1 and POD2 was significantly increased (p < 0.05); at the same time, the range of extension motion at POD2 and POD3 showed the opposite trend between the two groups (p < 0.05). The morphine equivalent of postoperative analgesia was significantly reduced (p < 0.05), and the time required for straight leg raising (SLR) was significantly shortened (p < 0.05). There was no significant difference between the two groups in terms of postoperative drainage, length of hospital stay, and complications such as infection, nausea, and vomiting (p > 0.05). CONCLUSION: The additional corticosteroids to multimodal cocktail periarticular injection can relieve the early pain intensity at rest after TKA, increase the early range of motion (ROM) of the knee joint, reduce the dosage of postoperative analgesics, and shorten the duration of time required for SLR. However, it has no effect on reducing postoperative complications and shortening the length of hospital stay.
