• Conditions: Surgery; Knee Osteoarthritis; Knee Arthropathy

• Registration Number: NCT06298721
• Lead Sponsor: The Cleveland Clinic

Brief Summary

This study is a randomized controlled trial to assess whether the implementation of a TKA Personalized Outcome Prediction Tool to set expectation, in addition to targeted interventions to address patients with poor baseline mental health and poor physical function, improves satisfaction at 1-year (when compared to standard of care).

Detailed Description

The potential candidates for the study are patients scheduled for primary TKA. Scheduled patients will be sent an invitation letter detailing the study's objectives and design. Should they choose to take part, individuals will be requested to utilize MyChart for the completion of PROMs. The information gathered from these PROMs will play a pivotal role in assessing their suitability for inclusion in the study. Subsequently, once deemed eligible, our coordinator will arrange a convenient session to meticulously review and facilitate the signing of the informed consent form (enrollment visit). This enrollment visit will take place approximately 2-3 months prior to the scheduled surgery. Subsequently, enrolled patients will be randomized in a 1:1 ratio to:

i) Standard of Care ii) Standard of Care + TKA Personalized Outcome Prediction Tool (Mental Health Screening/Intervention \& Physical Therapy Pre-surgery Assessments/Intervention)

TKA Personalized Outcome Prediction Tool aids in setting expectations for surgery and the results (calculated from patient information and baseline PROMs) will be provided and discussed with the patients by the surgeon.

The primary outcome of the study will be the proportion of patients who fail treatment, defined as patients who answer "no" to the PASS anchor question at 1-year postoperative. The treatment and control groups will be compared using a chi-square test between the randomized groups with p=0.05 as the threshold for statistical significance. We will follow the intent-to-treat principle, and patients assigned to the treatment/intervention arm will be analyzed as such regardless of his/her compliance with the intervention.

Arm && Interventions

Group	Intervention	Description
Standard of Care TKA	Standard of Care TKA	Patients scheduled to undergo TKA at Cleveland Clinic will follow the standardized TKA Care Pathway as part of Standard of care. Patients enter the TKA care path after consenting to undergo TKA for symptomatic knee pain that has not relieved with nonoperative measures. They stay in the care path until 90-days after the operation is complete. The TKA care path guides the care delivered through the preoperative, intraoperative and postoperative phases.
Standard of Care TKA + Personalized Outcome Prediction Tool with targeted interventions	Personalized outcome prediction tool + targeted interventions	Patients who are identified to have a TKA PROMs phenotype which includes lower than median scores for VR-12 MCS will be further screened for: Distress ➔ using the NCCN Distress Thermometer (DT) Depression ➔ using the Patient Health Questionnaire-9 Those patients with a score ≥ 8 on the DT, or a score ≥ 10 on the PHQ-9, or any response other than 0 to question 9 on the PHQ-9 will have a consult with Psychiatry and Behavioral Science to determine a mental health diagnosis. Patients who are identified to have a TKA PROMS phenotype which includes lower than median scores for KOOS-PS (score of =\<51.5) will be scheduled for a 4 to 8 week intervention of pre-rehabilitation. All patients who undergo the PT intervention will have a an assessment before and after the rehab TKA.

Primary Outcome Measures

Name	Time	Method
Satisfaction at 1 year	1 year	Patient Acceptable Symptom State (PASS) anchoring question of: "Taking into account all the activity you have during your daily life, your level of pain and also your activity limitations and participation restrictions, do you consider the current state of your knee satisfactory?" to measure satisfaction
