Abstract
We studied the hip abductor strength and Trendelenburg test prospectively in 100 patients undergoing total hip replacement via a lateral or posterior approach. In 49 patients, we used the lateral approach to implant the Charnley total hip replacement, and in 51 patients, the posterior approach to implant the Exeter total hip. Isometric abductor strength was measured with the kinetic communicator device and the Trendelenburg test was recorded preoperatively and at 3 and 12 months postoperatively. Of the original 100 patients, 83 were available for study at 3 months and 73 at 12 months. Hip abductor strength and the Trendelenburg test improved postoperatively in both groups, but we found no difference in hip abductor strength recovery at 3 and 12 months between the lateral approach and the posterior approach. Similarly there was no difference in the Trendelenburg test between the two groups 3 and 12 months following hip replacement.

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
