Multimodal Prehabilitation of Frail Patients Undergoing Elective Knee or Hip Replacement
Sponsor: University of Iceland
Summary
Background: Frailty is a geriatric syndrome of reduced physiologic reserve that increases surgical risk and is common among older adults undergoing hip or knee replacement. While prehabilitation has shown promise in enhancing outcomes, evidence from randomized controlled trials (RCTs) in frail orthopedic patients is limited. Objective: This study aims to evaluate the feasibility and preliminary data on the effectiveness of a multimodal prehabilitation program for frail patients undergoing elective hip or knee arthroplasty. Methods: A pilot RCT will be conducted at Landspítali-University Hospital. Patients ≥70 years scheduled for surgery with ≥2 months waiting time will be screened for frailty using PRISMA-7, the Clock Drawing Test, and Timed Up \& Go. Patients screening positive for any of the three screening tools will be randomized to multimodal prehabilitation or standard of care. The intervention includes comprehensive geriatric assessment, medication review, tailored physiotherapy using the Otago Exercise Programme, and nutritional counseling if at risk of malnutrition. We will conduct an external pilot for feasibility measures (overall enrollment, recruitment, retention, adherence). Secondary outcomes include physical performance, postoperative complications, patient-reported health status (WOMAC scale) and quality of life (EQ-5D-5L ), length of primary hospital stay, discharge location, falls postoperatively, 180-day readmission and 180-day mortality. Significance: This trial may aid in the design of larger RCT study and provide a signal of the role of multimodal prehabilitation on outcomes, including quality of life and health status among frail arthroplasty patients.

Multimodal Prehabilitation
The intervention will begin ≥2 months before planned surgery and consists of a multimodal prehabilitation program. Participants will undergo geriatric assessment with frailty evaluation, medication review, and optimization of comorbidities as needed. Patients at risk of malnutrition will receive nutritional assessment, counseling, and supplementation when indicated. All participants will receive individualized physiotherapy based on the Otago Exercise Programme, including strength, balance, and walking exercises. Patients will attend an initial physiotherapy session with follow-up visits and will be encouraged to perform exercises at home multiple times per week at moderate intensity.
