Abstract

fetched live from OpenAlex

weighted and unweighted pooled OR of having patellofemoral instability and apprehension test post-operatively as compared to pre-operatively was < 0.01.The Kujula score improved from a pre-operative score of 60.57 (95% CI: 54.92 e 66.22) to a post-operative score of 84.88 (95% CI: 80.87 e 88.89), while the Lysholm score improved from a pre-operative score of 61.81 (95% CI: 55.25 e 68.37) to a post-operative score of 92.26 (95% CI: 88.59 e 95.94).The difference in the pre-operative and post-operative Kujula scores and Lysholm scores were statistically significant (p < 0.001 and p < 0.001).The overall proportion of patients participating in sports pre-operatively was 77.91% (95% CI: 68.05 e 85.38), which is similar to the overall 75.58% (95% CI: 65.54 e 83.44) of patients participating in sports post-operatively (p ¼ 0.141).The overall Tegner score improved from 4.45 (95% 3.74 e 5.16) pre-operatively to 5.22 (95% CI: 4.62 e 5.82) postoperatively, though the improvement was not statistically significant (p ¼ 0.100).None of the surgical techniques or graft choice analyzed moderated the difference in outcomes post-operatively.Conclusion: Isolated MPFL reconstruction, without any concomitant procedures, can lead to good outcomes.This includes a significant decrease in the rates of patellofemoral instability and apprehension, a significant increase in functional outcomes as measured by Kujala and Lysholm scores, and the ability to return to pre-injury sporting activities.The different sources of graft (gracilis versus semitendinosus), types of implant used for femoral fixation (screw versus suture anchor), types of femoral fixation (bony versus soft tissue; anatomic versus non-anatomic), types of implant used for patellar fixation (suture anchor versus suture), types of patellar fixation (transpatellar tunnels versus soft tissue; anatomic versus nonanatomic), numbers of transpatellar tunnels used as well as types of graft configuration (single limb versus double limb) all did not affect the good post-operative outcomes after MPFL reconstruction.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
