Body Mass Index and Functional Mobility Outcome Following Early Rehabilitation After a Total Knee Replacement: A Retrospective Study in Taiwan
Bibliographic record
Abstract
OBJECTIVE: Obesity is associated with an increased risk of osteoarthritis, and the incidence of obese patients requiring a total knee replacement (TKR) has increased in recent years. A high body mass index (BMI) may influence post-TKR rehabilitation outcomes. We investigated the effects of obesity on functional mobility outcomes following post-TKR rehabilitation in Asian patients whose BMIs were not as high as those reported in similar studies performed in non-Asian countries. METHODS: A total of 113 patients were categorized as normal weight (n = 23), overweight (n = 32), class I obese (n = 31), or class II/III obese (n = 27). Patients were retrospectively followed up for 6 months after undergoing TKR followed by 2 months of active rehabilitation. Outcome measures were recorded at baseline and at the 2-month and 6-month followup assessments and included the Western Ontario and McMaster Universities Osteoarthritis Index and the following tests: functional reach, single-leg stance, ten-meter walk, timed up and go, chair rise, and stair climbing. RESULTS: A 4 × 3 (group × time) repeated-measures analysis of variance showed significant improvement in all of the outcome measures for all of the BMI groups at the 2-month and 6-month followup assessments (P < 0.05 for all). No significant intergroup differences at the 2-month and 6-month followup assessments were observed for any of the mobility measures except the functional reach and single-leg stance (P < 0.05). CONCLUSION: Patients with class II/III obesity benefit from early post-TKR outpatient rehabilitation and respond as well as patients with lower BMIs.

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.
