Background: When knee osteoarthritis worsens and conservative measures are ineffective in
reducing pain and improving function, total knee arthroplasty becomes the preferred course of
action, necessitating a postoperative rehabilitation program. Aim: To investigate effect of
physical exercises rehabilitation program on knee function for patients with end-stage
osteoarthritis undergoing knee arthroplasty. Design: This study employed a quasi-experimental
research design. Settings: The trauma unit, outpatient orthopedic clinic, and orthopedic surgery
department of Assiut University Hospital served as the study's locations. Sample: A sixty a
(60) patients who were scheduled to underwent knee arthroplasty were included in this study
after they were randomly divided into the study and control groups, (30) patients each. Tools:
I: Structured Patient Interview Sheet, Tool II: Knowledge assessment sheet, Tool III, Knee
Osteoarthritis Western Ontario, and McMaster Arthritis Index (WOMAC). Results: While there
was improvement in patient function and knee ability to specific activity for patients undergoing
knee arthroplasty during the program phases, the current study found a statistically significant
difference in knowledge between the study and control groups following program
implementation. Conclusion: Following knee arthroplasty, the patient's knowledge, function,
and knee ability to perform particular tasks were significantly enhanced by the application of
an exercise program. Recommendations: Applying physical exercise program as mandatory
clinical pathway for patient undergoing arthroplasty.
