Clinical effectiveness of a standardized community-based supervised post-acute rehabilitation model after total knee arthropathy: A pilot study.

Background: Hospital-based outpatient physiotherapy is the standard of care for subacute rehabilitation after total knee arthroplasty (TKA) in Singapore. This study explores the clinical effectiveness of a standardized rehabilitation model at community-based rehabilitation centers to align the appropriate utilization of tertiary and community rehabilitative resources. Methods: In this pilot study, patients who had undergone TKA were assigned to either control group (n=30) or to intervention group (n=29). The control group received usual hospital-based outpatient physiotherapy, while the intervention group received rehabilitation at a community-based rehabilitation center based on standardized institution protocol. Primary and secondary outcomes were assessed at baseline and at 3 months post TKA. Results: Baseline characteristics in both groups were not significantly different. All patients completed the study. At 3 months, there were no significant differences in the Time Up and Go test ( Conclusions: A community-based post-acute TKA rehabilitative model demonstrated improvements in functional outcomes, and reduced pain intensity in study participants, with these findings being similar to that of standard of care hospital-based outpatient physiotherapy. This model of care warrants further evaluation in larger clinical trials.
