Prevalence of rapidly progressive osteoarthritis of the hip following intra-articular steroid injections.

PMID 35596119WHAT IT FOUND
Rapidly progressive hip osteoarthritis occurred in 2.8% of patients after steroid injections.
Half of these cases appeared within three months, and most required hip replacement. Older age was linked to higher risk, but the study cannot prove the injection caused the joint destruction.
Key findings
01The prevalence of rapidly progressive osteoarthritis of the hip was 2.8% among patients who received intra-articular steroid injections.
02Patients who developed rapidly progressive osteoarthritis were significantly older than those who did not.
03The majority of patients who developed rapidly progressive osteoarthritis required total hip arthroplasty or resurfacing.

What it does not show
The study was retrospective, so clinical data like symptom duration were incomplete and not all patients had the same type of imaging before and after the injection. It is impossible to determine if the steroid injection caused the joint damage or if this was just the natural progression of severe osteoarthritis. Only patients who had both pre- and post-injection imaging were included, which might miss cases or alter the true prevalence rate. There is no universally accepted grading system for rapidly progressive osteoarthritis, so the researchers used a modified hybrid classification.
Declared interests
The study was supported by the National Institutes of Health (N.I.H., Extramural). No other specific conflicts of interest are detailed in the provided text.
The easy way to misread this
Do not conclude that steroid injections cause rapidly progressive osteoarthritis. This study only shows an association in a specific group of patients, and the authors state that the relationship between the injections and the joint destruction remains unknown.
