Analysis of early curative effect of TKA surgery strategy guided by personalized tibial prosthesis rotation alignment
Bibliographic record
Abstract
Abstract Background To explore the influence of individualized positioning of tibial prosthesis rotation alignment to guide total knee arthroplasty (TKA) surgery strategy on the early postoperative effect. Method A total of 60 patients who underwent TKA in our hospital from January 2019 to March 2020 were divided into two groups: personalized operation group and traditional operation group, with 30 patients each group. The general data such as age, sex, operation time, intraoperative blood loss and hospital stay were recorded. Range of motion (ROM), visual analogue scale (VAS), knee society score (KSS), The Western Ontario and McMaster Universities Arthritis Index (WOMAC), and Oxford knee score (OKS) were recorded before, 3 months and 12 months after operation and the vertical angle between APA and STEA' was θ, the mechanical axis of lower extremities (MA) and patellofemoral index (PFI) 3 months and 12months after operation were measured to evaluate the postoperative effect. Results 3 months after operation, the ROM, VAS, KSS, vertical angle θ and PFI scores of personalized positioning group were (108.6 ± 8.27), (1.20 ± 0.56), (88.15 ± 2.54), (0.85 ± 1.08) and (0.97 ± 0.10) respectively were better than traditional operation group (102.80 ± 7.72), (2.20 ± 0.67), (83.60 ± 3.85), (7.12 ± 0.99), (1.34 ± 0.20). 12 months after operation, the ROM, VAS, KSS, vertical angle θ and PFI scores of personalized positioning group were (118.3 ± 7.26), (0.67 ± 0.48), (91.83 ± 1.74), (0.35 ± 1.03), (0.96 ± 0.15) respectively were better than traditional operation group (114.1 ± 8.09), (1.18 ± 0.83), (89.93 ± 2.50), (6.24 ± 0.69), (1.28 ± 0.19). There was no significant difference in MA, WOMAC and OKS after operation. Conclusion Personalized tibial prosthesis rotation alignment guide TKA strategy can more accurately obtain the prosthesis rotation alignment and lower limb force lines, and then guide TKA surgery, in order to achieve better results in the early postoperative period.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
