Abstract
Aim: This study assessed pain and function at 5-9years postinjection in a subset of patients who received intradiscal platelet-rich plasma (PRP) injections for moderate-to-severe lumbar discogenic pain. Patients & methods: All patients received injections of intradiscal PRP in a previous randomized controlled trial. Data on pain, function, satisfaction, and need for surgery were collected at one time point of 5-9years postinjection and compiled with existing data. Results: In comparison to baseline, there were statistically significant improvements in pain and function (p<0.001). All improvements were clinically significant. Six patients had undergone surgery during the follow-up period. Conclusion: This subset of patients demonstrated statistically and clinically significant improvements in pain and function at 5-9years postinjection.
