A retrospective analysis of postrehabilitation outcomes following total knee arthroplasty
Bibliographic record
Abstract
Abstract Background and purpose Total knee arthroplasty (TKA) is one of the most frequently performed orthopaedic procedures in Canada. Despite the frequency at which TKAs are performed, few studies have examined the association between postoperative outcomes and long‐term functional outcomes following group‐based rehabilitation in Canada. The primary objective of the present study was to examine changes in flexion and extension from intake to discharge from rehabilitation in patients in Saskatchewan, Canada. A secondary objective was to explore the demographic and medical predictors of range of motion in TKA patients, and treatment duration. Methods A retrospective chart review from an outpatient rehabilitation clinical database was conducted between September 2014 and December 2016, and assessed demographic and medical variables. Results A total of 672 patient charts were included in the study. Significant improvements ( p < 0.001) were noted from intake to discharge from rehabilitation for flexion and extension. Right‐side TKA, flexion at intake and the length of treatment predicted flexion at discharge from rehabilitation ( R 2 = 0.23). Gender, right side TKA, extension at intake and the length of treatment predicted extension at discharge from rehabilitation ( R 2 = 0.23). Lastly, age, flexion at intake and extension at intake predicted length of treatment in the rehabilitation programme ( R 2 = 0.21). Conclusions Patients who participated in rehabilitation following TKA experienced improvements in flexion and extension. Those with decreased flexion and extension after TKA may be less likely to experience a desirable range of motion, indicating a need for more intensive targeted rehabilitation in this group, and adjustments in hospital and community care.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
