A Novel Treatment of Painful Medial Collateral Ligament Calcification (Pellegrini–Stieda Syndrome): A Case Report
Bibliographic record
Abstract
ABSTRACT: A 63-year-old healthy woman was diagnosed clinically and radiographically with Pellegrini-Stieda syndrome. She had failed to improve with 6 months of conservative management using oral anti-inflammatories and physiotherapy. Local corticosteroid injections were offered on 2 occasions, 4 months apart, and provided excellent but only temporary relief of symptoms. The patient agreed to undergo ultrasound-guided percutaneous lavage, followed by platelet-rich plasma infiltration of the Pellegrini-Stieda lesion instead of being referred for surgery. The patient was assessed clinically and radiographically at 12 weeks and 18 months postprocedure. At both appointments, the patient reported a significant reduction in pain and improvement in function as rated by the Lower Extremity Function Scale (improvement of 20 points at 12 weeks and an improvement of 16 points at 18 months postprocedure). Radiographically, the Pellegrini-Stieda lesion was no longer visible at either follow-up interval. In conclusion, ultrasound-guided percutaneous calcific lavage followed by autologous platelet-rich plasma infiltration may be an effective way to treat refractory cases of Pellegrini-Stieda syndrome.

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.
