Preoperative physical function influences on stair climbing ability 1 month after TKA.
Bibliographic record
Abstract
Introduction: Knee osteoarthritis (OA) is the one of the most common significant disease that is a leading cause of pain and swelling of joint, functional disability and impairment to the quality of life.Purpose: This study was undertaken to identify preoperative physical performance factors predictive of stair climbing ability 1 month following total knee arthroplasty.Method: In this prospective cohort study, we assessed a total of 84 patients who underwent a primary unilateral total knee arthroplasty (TKA). The gait parameters, isometric knee extensor and flexor strength of both knees, range of motion (ROM) of flexion and extension of surgical knee, 6 minute walk test (6MWT), timed up-and-go test (TUG), stair climbing test (SCT), Western Ontario McMaster Universities Osteoarthritis Index (WOMAC), EuroQoL five dimensions (EQ-5D) questionnaires, and visual analog scale (VAS) of knee pain were assessed before and 1 month after TKA.Results: In the bivariate analyses, the postoperative SCT-ascent had a significant positive correlation with the SCT-ascent, SCT-descent, TUG, preoperative age, and a significant negative correlation with the preoperative 6MWT, peak torque (PT) extensor of surgical knee, PT flexor of surgical knee, PT extensor of the non-surgical knee, PT flexor of the nonsurgical knee. The postoperative SCT-descent had a significant positive correlation with the SCT-ascent, SCT-descent, TUG, preoperative age, WOMAC function, and a significant negative correlation with 6-MWT, PT extensor of surgical knee, PT flexor of surgical knee, PT extensor of the nonsurgical knee, PT flexor of the nonsurgical knee. In the linear regression analyses, the preoperative TUG and PT extensor of surgical knee were factors predictive of the postoperative SCT-ascent. In addition, the preoperative SCT-descent and age were factors predictive of the postoperative SCT-descent.Conclusions: According to preoperative predictive factors, we can propose the pre- and postoperative rehabilitation strategies to improve stair climbing ability in the early stages following TKA.

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.
