Is it possible to predict which patients are most likely to benefit from intra-articular corticosteroid injections? A systematic review.

AIM: Intra-articular corticosteroid injections (IACIs) can reduce osteoarthritis-related pain, with differing levels of response across patient groups. This systematic review investigates what is known about the positive and negative predictors of outcomes in patients with osteoarthritis who undergo IACIs. METHODS: We systematically searched the Medline, Embase, and Cochrane databases to May 2023 for studies that evaluated patients undergoing IACIs for osteoarthritis and reported on predictors of outcomes in these patients. RESULTS: Eight studies were included. Two were placebo-controlled trials, six were observational studies. Due to the heterogeneity of outcomes and variables between the studies, it was not possible to pool the results for formal meta-analysis. Higher baseline pain, older age, higher BMI, lower range of movement, higher Kellgren-Lawrence radiographic score, joint effusion, and aspiration were shown to be predictors of a positive response to IACIs in some of the included studies. However, other studies showed no difference in response with these variables, or a negative correlation with response. Sex, smoking, mental health status, hypertension/ischaemic heart disease, diabetes mellitus, duration of symptoms, and socioeconomic status did not demonstrate any correlation with the prediction of positive or negative outcomes after IACIs. CONCLUSION: Several patient features have been identified as positive predictors of outcomes following IACIs. However, this systematic review has identified inconsistent and variable findings across the existing literature. Further research with standardization of IACI administration and outcome measures is required to facilitate further analysis of the reliability and significance of predictive factors for response to IACIs.

Rehabilitation after musculoskeletal injury: European perspective.

Trauma is one of the main causes of death in younger people and ongoing disability worldwide. In Europe, while there is generally good organization of trauma reception and acute treatment, rehabilitation from major musculoskeletal injuries is less well defined and provided. This article documents the diverse approaches to rehabilitation after major injury in 6 European nations. The recognition of need is universal, but achieving a robust rehabilitation strategy is more elusive across the varying health care systems. Switzerland has the most robust service in the insured population. In the other countries, particularly where there is a reliance on public institutes, this provision is at best patchy. In the Netherlands, innovative patient-empowering strategies have gained traction with notable success, and in the United Kingdom, a recent randomized trial also showed this approach to be reproducible and robust. Overall, there is a clear need for learning across the national systems and implementation of a minimum set of standards.
