Effectiveness of Intra-articular Botulinum Toxin Type A with Hyaluronic Acid Compared to Intra-articular Platelet-rich Plasma with Hyaluronic Acid in Improving Pain and Functional Limitation in Knee Osteoarthritis
Bibliographic record
Abstract
Abstract Background: Knee osteoarthritis (KOA) is the most common cause of chronic knee pain causing functional disability and dependency. Multiple interventions have been used in reducing pain and improving functionality. We intend to compare the efficacy of intra-articular platelet-rich plasma (PRP) and hyaluronic acid (HA) with botulinum toxin type A and HA in bilateral Grade 3 and 4 KOA. Methods: Prospective single-blinded randomized controlled trial conducted for 6 months. Among 54 participants, 27 received intra-articular botulinum toxin type A with HA (Group A), and the other 27 received intra-articular PRP with HA (Group B), single session. Pain (Numerical Rating Scale [NRS]) and functional limitation (Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC]) were assessed at 2, 4, 12, and 24 weeks postintervention. Effect of weight and physiotherapy on NRS and WOMAC score were assessed. P <0.05 was considered statistically significant. Data were analyzed by statistical software R version 4.2.3. Results: Fifty-four participants were enrolled. There was no loss to follow-ups. Except for age ( P < 0.001) and mean height ( P = 0.013), other demographic data were insignificant. Preprocedural NRS was significantly high in Group A ( P = 0.04). Overall NRS postprocedure was significantly lesser in Group B, P < 0.001. The mean WOMAC score postprocedure was significantly low in Group B, P < 0.001. Group B had increased heart rate which was statistically significant ( P = 0.051). The mean reduction in WOMAC score was observed with regular physiotherapy in Group B ( P = 0.023). Reduction in weight was directly proportional to reduction in NRS ( P = 0.015). Conclusion: Intra-articular PRP with HA, single session, is effective in improving pain, functionality, and safe in Grade 3 and 4 KOA.

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.
