Steroid injections are still commonly used in the clinical setting in the treatment of sacroiliac joint (SIJ) pain. A common issue is that steroid injections only provide short-term relief. With the rise in popularity of platelet-rich plasma (PRP) injections, the authors of the current study investigated the efficacy and safety in administering PRP injections for SIJ-related low back pain. It was hypothesised that if beneficial, then PRP injections could potentially enhance tissue healing and may provide longer-term pain relief.
