The Feasibility of a Nurse-Initiated Weighted Blanket in Orthopedic Surgical Patients Undergoing Total Knee Arthroplasty

The purpose of this study is to explore the acceptability and feasibility of weighted blankets in total knee replacement (TKR) patients. The study also aims to measure the difference in anxiety of adult orthopedic patients in need of total knee arthroplasty surgery who receive weighted blanket before and after surgery compared to those who receive a non-weighted blanket.

Inclusion Criteria: 1. Adults aged 18 years and older 2. Adults undergoing elective total knee arthroplasty at NYU Langone Orthopedic Hospital. 3. Adults who are scheduled to receive spinal anesthesia. 4. Subjects with a planned same day discharge to home from the PACU Exclusion Criteria: 1. cognitive disability that would interfere with their ability to complete the study's pre and post assessments (e.g. dementia, non-verbal) 2. subject disclosed history of pre-existing anxiety disorder, claustrophobia, epilepsy, respiratory conditions (e.g. obstructive sleep apnea (OSA), asthma), skin conditions (e.g. pressure injury), which are contradictions for weighted blanket.
