When knee osteoarthritis worsens and conservative measures are ineffective inreducing pain and improving function, total knee arthroplasty becomes the preferred course ofaction, necessitating a postoperative rehabilitation program.

To investigate effect ofphysical exercises rehabilitation program on knee function for patients with end-stageosteoarthritis undergoing knee arthroplasty.

This study employed a quasi-experimentalresearch design.

The trauma unit, outpatient orthopedic clinic, and orthopedic surgerydepartment of Assiut University Hospital served as the study's locations.

A sixty a(60) patients who were scheduled to underwent knee arthroplasty were included in this studyafter they were randomly divided into the study and control groups, (30) patients each.

I: Structured Patient Interview Sheet, Tool II: Knowledge assessment sheet, Tool III, KneeOsteoarthritis Western Ontario, and McMaster Arthritis Index (WOMAC).

While therewas improvement in patient function and knee ability to specific activity for patients undergoingknee arthroplasty during the program phases, the current study found a statistically significantdifference in knowledge between the study and control groups following programimplementation.

Following knee arthroplasty, the patient's knowledge, function,and knee ability to perform particular tasks were significantly enhanced by the application ofan exercise program.

Applying physical exercise program as mandatoryclinical pathway for patient undergoing arthroplasty.
