Efficacy of Intraarticular Knee Injection of PRP (Platelet Rich Plasma) vs Steroid (Triamcinolone Acetate) for the Treatment of Primary Knee Osteoarthritis Grade I & II
Bibliographic record
Abstract
Objective: To assess the effectiveness of PRP (Platelet Rich Plasma), and to compare with Triamcinolone 40mg (Steroid) on functional activity, stiffness and pain in Grade I & II Knee OA. Method: A comparative cross sectional study was conducted at outdoor departments of Advanced Pain Relief Center, Lifeline Hospital Lahore (Pakistan) from January 2022 to December 2022. The present study included a total of 235 participants, out of whom 190 individuals were deemed eligible for inclusion based on predetermined criteria. The remaining 45 participants were excluded from the study due to non-adherence to eligibility criteria and lack of approval from institutional ethical committee. Out of a total of 190 subjects enrolled in the study, 64 (33%) were characterized as male while 126 (67%) were classified as female. The participants' mean age was 53.5 ± 6.4 years. Alternative patients were treated with intra-articular injection of either triamcinolone 40mg or PRP. Patients randomized in Steroid group (n=95) were gives intraarticular 40mg Triamcinolone acetate (1ml) along with 2ml of Local anaesthetic Lignocaine 1%, whereas patients randomized in PRP group (n=95) were injected 5ml PRP. “The Western Ontario and McMaster Universities Arthritis Index” (WOMAC) Scale was used for functional disability and pain before and after the therapy for the targeted knee joint at the baseline 1 week, 5 weeks, 8 weeks and 20 weeks follow-ups. Visual Analogue Scale (VAS) scores were also recorded for pain. Data analysis was done by using SPSS version 20. Results: There wasn't any serious adverse effect observed during the study and follow-ups. 25 WOMAC functional activity scale showed statistically significant improvement with Intraarticular knee injection of PRP compared to steroids(40.64±1.87vs.27.17±6.01)(p=0.000). WOMACpainscaleresultsalsodemonstrated that intraarticular knee injection of PRP was more effective in reducing knee pain than steroids (p = 0.000) at 20 weeks follow-up. Conclusion: On the basis of the results of our study, we concluded that platelet rich plasma is more effective than intra-articular steroids in terms of improvement in functional activity and reduction of pain in patients with Grade I & II knee osteoarthritis. Both PRPand steroid intraarticular injections are safe.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
