1. Method: On the day of admission, a research assistant provided a verbal explanation of the preoperative rehabilitation exercise regimen and distributed a guidance manual. Participants are advised to perform self-directed exercises 2-3 times daily according to the manual from admission day to surgery day (preoperative). They were also advised to promptly inform ward medical staff of any unusual conditions or concerns. 2. Preoperative rehabilitation exercise regimen: * Pulmonary function exercises: including abdominal breathing exercises and effective cough learning. * Quadriceps strength exercises: including straight leg raises and lateral leg raises. * Knee range of motion exercises: including knee flexion exercises and knee extension exercises. * Lower limb thrombosis prevention exercises: ankle pump exercise

1. The navigator's guidance preoperative rehabilitation exercise regimen was identical to that of the control group, but offered full-period guidance, including the following: 1. On the day of admission, in addition to the same measures as the control group, the navigators demonstrated the exercise movements and required participants to perform return demonstrations to ensure mastery of the exercises. 2. During the preoperative period, navigators conducted daily ward visits, offering two 20-minute supervised sessions and sending nightly exercise reminders between 7:00-8:00 PM. 2. Navigation services covered seven areas: establishing contact with participants or carers, providing disease-related education, assessing needs and facilitating resources, offering social and emotional support, providing interpretation services upon request, identifying and resolving exercise barriers, and promoting self-management.
