Abstract

fetched live from OpenAlex

This chapter presents a case scenario of a 65-year-old woman with rheumatoid arthritis who presents with a painful right total knee arthroplasty (TKA) five years after index surgery. Poor patellar bone stock may be encountered at the time of revision TKA. Options such as gull-wing osteotomy, bone graft augmentation, cemented all-polyethylene biconvex prostheses, and trabecular metal prostheses have been introduced to address poor patellar bone stock at the time of revision TKA. Surgeons must understand the current evidence before offering a secondary resurfacing to patients with anterior knee pain and an unresurfaced patella. Most modern patellar components are symmetrical domes and compatible with the trochlea of most femoral components. Revision of the patellar component is associated with several complications, including fracture, avascular necrosis, and aseptic loosening. The chapter provides recommendations for implementing evidence-based practice in the clinical setting.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
