Image guided PRP and prolo work QUITE well in issues with soft tissue injury.
You want to write the protocol for intradiscal PRP?
Discs are soft tissue.
Just need PRP and
lime jello. Mmm, jello.

Abstract
Degenerative disorders of the intervertebral discs (IVDs) are generally characterized by enhanced matrix degradation, angiogenesis, innervation, and increased expression of catabolic cytokines. In this study, we investigated the effects of inflammatory cytokines, IL-1β, and TNF-α, on the expression of an angiogenic factor, vascular endothelial growth factor (VEGF), and neurotrophic factors, nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF), in human IVD degeneration. IL-1β and TNF-α stimulated the gene expression of VEGF, NGF, and BDNF in nucleus pulposus (NP) cells isolated from patient tissues. Immunohistochemical results demonstrated a positive correlation between IL-1β and VEGF/NGF/BDNF expression in human IVD tissues. RNA expression analysis of patient tissues also identified positive correlations between VEGF and platelet endothelial cell adhesion molecule-1 (PECAM-1) and between NGF/BDNF and protein gene product 9.5 (PGP9.5). Our findings suggest that IL-1β is generated during IVD degeneration, which stimulates the expression of VEGF, NGF, and BDNF, resulting in angiogenesis and innervation.

Abstract
We have previously shown that administration of
platelet-rich plasma-impregnated gelatin hydrogel microspheres (PRP-GHMs) into a degenerated intervertebral disc (IVD) markedly suppresses progression of IVD degeneration. In the current study, we characterized the in vivo effects of PRP-GHM treatment in a degenerated IVD model in rabbit. On magnetic resonance images, the IVD height was significantly greater after treatment with PRP-GHMs compared with phosphate-buffered saline-impregnated GHMs, PRP without GHMs, and needle puncture only. Water content was also preserved in PRP-GHM-treated IVDs. Consistent with this observation, the mRNA expression of proteoglycan core protein and type II collagen was significantly higher after PRP-GHM treatment compared with other treatment groups. No proliferating cells were found in the nucleus pulposus and inner annulus fibrosus in any groups, but the number of apoptotic cells in the nucleus pulposus after PRP-GHM treatment was significantly lower than that after other treatments. These results provide an improved understanding of the therapeutic effects of PRP-GHM treatment of degenerated IVDs.
