Effect of autologous platelet-rich plasma (PRP) on low back pain in patients with prolapsed intervertebral disc: A randomised controlled trial

BACKGROUND AND AIMS: Prolapsed intervertebral disc (IVDP) is a major cause of low back pain. Platelet-rich plasma (PRP) has emerged as a viable option for these patients, with fewer adverse effects and long-term sustainability of pain relief. This double-blinded, randomised study aimed to evaluate the effect of autologous PRP on low back pain in patients with IVDP. METHODS: A total of 42 patients with IVDP were randomised either to the autologous PRP (n = 21) group or control (epidural local anaesthetics with steroids; n = 21) group. Change in pain was assessed using the Numeric Rating Scale (NRS). Impact of treatment was assessed using the Global Perceived Effect (GPE) scale. All the patients were followed up for six months. Data was compared using Chi-square, independent sample t, and Mann–Whitney U tests. RESULTS: The two groups were similar in their demographic and clinical profile. The baseline mean NRS ± standard deviation (SD) was 6.91 ± 0.94 in the PRP group and 7.38 ± 1.16 in the control group (P = 0.099). At six months, the mean NRS ± SD was 1.43 ± 0.75 in the PRP group compared to 5.43 ± 0.75 in the control group (P < 0.001). The GPE score was also found to be significantly higher in the PRP group, compared to the control group in the final assessment (P < 0.001). During the course of the study, the PRP group showed a consistent decline in NRS, whereas the control group showed an initial decline followed by consistent increase in NRS. CONCLUSION: PRP provided sustained relief from low back pain due to IVDP and can be recommended as a safe and promising alternative to epidural local anaesthetics and steroids.
