Abstract
OBJECTIVES: To compare the effectiveness and safety of posterior-substituting (PS) with cruciate-retaining (CR) total knee prostheses after the elimination of confounding variables. METHODS: Between January 2008 and June 2012, a total of 32 subjects who had bilateral arthritis of the knees agreed to have one knee replaced with a PS total knee design and the other with a CR design. In addition to postoperative complications, clinical outcomes (Knee Society Score, Range of Motion, Western Ontario and McMaster Universities Arthritis Index, as well as radiographic findings) were evaluated preoperatively, and at 2-week, 3-month, 12-month, and 24-month follow-up. RESULTS: At the 24-month follow-up interval, no benefit of CR design was observed over PS design regarding functional assessment, patient satisfaction, or postoperative complication. However, the PS total knee design did display statistically significant improvements in range of motion as compared with the CR design. CONCLUSION: While comparable regarding supporting good clinical outcomes, the PS design does appear to support significantly improved postoperative range of motion when compared with the CR design.

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 it
