Abstract

The present meta-analysis compared the efficacy of intra-articular hyaluronic acid (HA) injections in patients with early to mild knee osteoarthritis (OA) (Kellgren Lawrence I-II) versus other commonly injected biologically active compounds using patient-reported outcome measures (PROMs). The outcomes of interest were the visual analogue scale (VAS) and the Western Ontario McMaster Osteo-Arthritis Index (WOMAC) scores. This study was conducted according to the 2020 PRISMA statement. In April 2024, PubMed, Web of Science, Google Scholar, and Embase were accessed without time constraints. All the randomised controlled trials (RCTs) investigating the efficacy of intra-articular HA injections in the early stages of knee OA were accessed. Data concerning the VAS, WOMAC, and related subscales were collected at baseline and the last follow-up. Only studies clearly stated the degrees of advancement of OA using the Kellgren-Lawrence scoring system were used. The literature search resulted in four RCTs (390 patients). The mean length of the last follow-up was 7.5 ± 3.0 months. 72.3% (282 of 390) of the patients were women. The mean age of the patients was 58.1 ± 3.2 years, and the mean BMI was 27.3 ± 3.2 kg/m . At the last follow-up, no difference was found between HA and the control group in VAS, WOMAC, and related subscales. In patients with early to mild knee osteoarthritis, the current level of evidence suggests that intra-articular injections using HA performed similarly to other biologically active compounds commonly injected in the knee joint for a minimum of three months. Level I, meta-analysis. [Abstract copyright: © 2024. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.]
