A comparative analysis of pain reduction following a single intra-articular injection of platelet-rich plasma, steroid or normal saline in chronic external shoulder impingement syndrome

Background: Shoulder impingement is a common diagnosis for patients with pain and dysfunction of shoulder joint. Due to its chronicity clinical manifestation the syndrome, there need find new therapies that collaborate improve management. Methods: A hospital based descriptive, epidemiological study was conducted 150 patients. The were divided in following three groups 50 each: Platelet-rich plasma (PRP) group: received PRP, steroid injection normal saline injection. Baseline visual analogue scale (VAS) score on overhead activities recorded. After 4th week, 12th 24th examined outpatient clinic. main outcome measure using VAS. Results: VAS improved significantly PRP group Steroid compared at 12th-week 24th-week follow-up periods post injection, as per ANOVA test (p<0.05). Conclusions: steroids, both can be considered effective methods treat chronic syndrome (SIS) less invasive surgical treatment. They hence function syndrome.
