Functional Outcome and Pain Relief After Pulsed Radiofrequency of Saphenous Nerve in Medial Compartment Knee Osteoarthritis: A Randomised Double-Blind Trial
Bibliographic record
Abstract
Background and aims: Pulsed radiofrequency (PRF) of saphenous nerve (SN) has shown effective pain relief in knee pain due to knee osteoarthritis (KOA). Since adductor canal (AC) contains other sensory nerves innervating the medial part of knee joint apart from SN. We compared the PRF of SN within and outside the AC for their quality and duration of pain relief in knee osteoarthritis of medial compartment (KOA-MC). Methods: We conducted a randomised prospective study in 60 patients with anteromedial knee pain due to KOA-MC. Patients in group A received PRF-SN and those in group B, PRF-AC. Primary objectives were, comparison of pain by visual analogue scale (VAS) score and changes in quality of daily living by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and OXFORD knee scores (OKS). Secondary objectives were, comparison of analgesic requirements using Medicine Quantification Scale (MQS) scale and block related complications. Intra group comparison was done by Analysis of variance (ANOVA). Inter group normally distributed data was assessed by student's t-test, non-normally distributed and ordinal data by Mann-Whitney U-test and categorical data by Chi-square test. A p value of < 0.05 was considered significant. Results: VAS scores were significantly lower in Gr-B at 12 weeks. The WOMAC scores and OXFORD scores at 4, 8, 12 and 24 weeks were significantly lower in Gr-B compared to Gr-A. Conclusion: The PRF-AC provides better pain relief and functional outcome than PRF-SN however, duration of pain relief was not significantly different.

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.
