Abstract

fetched live from OpenAlex

Background: Osteoarthritis (OA) is a common long-term condition that greatly contributes to disability among older adults. This disorder influences the entire joint, making it particularly difficult to regenerate articular cartilage, especially when active inflammation is present. Being a key weight-bearing joint, the knee is especially prone to OA, which makes it one of the foremost contributors to disability around the globe. Despite its extensive effects, there have been impressive advancements in treatment options in recent years. Methods: The prospective observational study was conducted in four sites which included 150 patients and evaluated a total of 216 knees that received total knee arthroplasty (TKA) with the EXCEL MEDIAL PIVOTAL KNEE SYSTEM (EMPK) prosthesis. Clinical outcomes were assessed utilizing established patient-reported outcome measures (PROMs), including the Knee Society Score (KSS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Oxford Knee Score (OKS), both prior to the surgery and six months following it. Results: The study involved an average age of 65.7±7.19 years with a greater proportion participated by female patients. After six months post-surgery assessment the mean Oxford Knee Score (OKS) rose significantly from 13.4±3.5 prior to surgery to 30.0±4.1 (p

Full frame distilled prediction

Teacher imitation

Not 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.
