Mean pain score reduction following intra-articular injection of autologous platelet rich plasma in early knee joint osteoarthritis

Aim: to determine the mean pain score reduction on visual analogue score before and after intra-articular injection of autologous platelet rich plasma in early knee osteoarthritis. methods: this quasi-experimental study was conducted at lady reading hospital,peshawar over a period of one year from 1st july 2014 to 30th june 2015 and comprised 178 patients. results: there were 35% males and 65% female patients with mean age 60±2.77 years. initially 90% patients had moderate pain (vas score 5-7) and 10% patients had severe pain (vas score >7) with mean pain score was 5.67±1.37 but after intra articular injection 10% patients didn't had pain,50% patients had mild pain (vas score 1-4) and 40% patients had moderate pain (vas score 5-7) with mean pain score was 5.67±.37. intra-articular injection reduces the pain from 5.67±1.37 to 5.67±1.37. conclusion: intra-articular injection of autologous platelet rich plasma is an effective and safe method of treatment in term of reduction of pain in early knee osteoarthritis.
