A tertiary care interventional study on autologous platelet-rich plasma regenerative therapy for Grade III knee osteoarthritis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPlatelet-rich plasma (PRP) therapy is widely used in regenerative medicine, with proven efficacy in mild-to-moderate knee osteoarthritis (OA). However, its role in advanced OA (Kellgren-Lawrence Grade III) remains uncertain.
objectiveThe objective of the study was to evaluate the effectiveness of PRP therapy in reducing pain and improving function in patients with Grade III bilateral knee OA.
methodsA prospective interventional study was conducted on 29 patients with Grade III bilateral knee OA. Each patient received four intra-articular PRP injections per knee (7-8 ml; 2-3 × concentration) at 4-5-week intervals. PRP was prepared using MARSPILL criteria: Non-activated, leukocyte-rich, double-spin, in a closed system, and administered within 60 min of preparation. The PRP preparation process was supervised by the transfusion medicine department. Western Ontario and McMaster Universities Arthritis Index (WOMAC) scores were recorded at baseline and at 3, 6, and 12 months posttreatment, along with monitoring for adverse events.
resultsMean WOMAC total scores improved significantly from 58.28 ± 7.7 at baseline to 27.48 ± 9.9, 26.31 ± 6.9, and 29.59 ± 7.3 at 3, 6, and 12 months, respectively (all
conclusionFour sessions of standardized PRP therapy significantly reduced pain and improved function in patients with bilateral Grade III knee OA for up to 1 year. This therapy may serve as a temporizing measure before definitive surgical intervention.
