Effectiveness of betamethasone dipropionate versus methylprednisolone acetate intra-articular injection in the management of pain in primary osteoarthritis of the knee
Bibliographic record
Abstract
Background: Knee osteoarthritis is a chronic degenerative condition often viewed as an inevitable aspect of aging. It leads to the progressive deterioration of articular cartilage, resulting in pain and significant limitations in global movement. Intra-articular steroid injections are effective for pain control and functional improvement. This study focuses on Betamethasone Dipropionate and Methylprednisolone Acetate, both of which have shown promising outcomes, evaluated at the Korle Bu Teaching Hospital. Objective: The study aimed to compare the effectiveness of betamethasone dipropionate and methylprednisolone acetate in managing Kellgren Lawrence (KL) stage 2 to 4 primary knee osteoarthritis. Design: This was a single-blinded comparative study conducted at the Orthopaedic Clinic of a tertiary hospital. Participants: Patients with osteoarthritis in one or both knees, presenting with a pain score of ≥4 on a 0-10 Visual Analogue Scale (VAS), were included. Main Outcome Measure: Effectiveness in controlling pain and improving function. Results: The average age of participants was 60 years. At two weeks, the P-values for VAS and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores between groups A and B were 0.495 and 0.927, respectively. At four weeks, these values were 0.810 and 0.372. However, by twelve weeks, the P-values for VAS and WOMAC scores were 0.026 and 0.0235, indicating significant differences. Conclusions: Both steroid injections provided symptom relief; however, Betamethasone Dipropionate demonstrated superior long-term effectiveness compared to Methylprednisolone Acetate, offering better sustained pain relief beyond eight weeks. Funding: None declared.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
