NCT06267482

Brief Summary

This is a prospective, randomized controlled trial using the cruciate retaining, MC Persona to comparing the conventional TKA to ROSA assisted TKA. Patients will be randomized to one of three study trial arms.

  1. 1.Standard of care medial parapetallar approach (Control)
  2. 2.ROSA PSA medial parapetallar approach
  3. 3.ROSA PSA medial subvastus approach Participants will be followed for 1 year post surgery with a combination of perioperative parameters, imaging, patient reported outcomes, functional outcomes, blood and tissue sampling for inflammatory information and activity levels.

Outcome Measures

Primary Outcomes (8)

  • Functional Outcome - Weight-bearing CT scan

    Patients will undergo a weight-bearing CT scan to examine implant migration and bone position in the knee.

    Pre-operation, 1-3 days post-op, 6-weeks post-op, and 1-year post-op

  • Functional Outcome - 3D Ultrasound

    Patients will undergo a 3D Ultrasound to measure the inflammatory characteristics including Synovial fluid and synovial thickness for fibrosis in the supra-patellar region of the knee

    Pre-operation, 6-weeks post-op, 3-months post-op and 1-year post-op

  • Functional Outcome - Timed Up and Go test

    Patients will undergo a Timed Up and Go (TUG) test. Patients will have to get up from a seated position, walk 10 feet, turn around and walk another 10 feet. This test is used to examine the function of the lower extremities. A time improvement of 2.27 Seconds will be considered clinically meaningful

    Pre-operation, 6-weeks post-op, 3-months post-op and 1-year post-op

  • Patient health status - Knee Society Score

    This will be done by comparing the Knee Society Score (KSS) Patient-reported outcome measurement questionnaire given to patients. The KSS questionnaire looks at several factors such as patient satisfaction (scale from 1-5, 5 being the best), Patient expectation (scale from 1-5, 5 being the best) and patient's pain during activities (scale from No pain to severe pain)

    Pre-operation, 6-weeks post-op, 3-months post-op and 1-year post-op

  • Patient health status - EuroQuol Survey

    This will be done by comparing the EuroQuol (EQ-5D) Patient-reported outcome measurement questionnaire given to patients. EQ-5D looks at the overall quality of life of a patient. The survey has 2 sections, the first asking the patient to best describe their health (Scale from Unable to perform the activity to no problem performing the activity) and an overall health assessment (scale 0-100, 100 being the best health you can imagine)

    Pre-operation, 6-weeks post-op, 3-months post-op and 1-year post-op

  • Patient health status - Knee Injury and Osteoarthritis Outcome Score

    This will be done by comparing the Knee Injury and Osteoarthritis Outcome score (KOOS) Patient-reported outcome measurement questionnaire given to patients. The KOOS survey looks at the pain and function of the operated knee. Patients will be asked questions about the pain they feel during activities (Scale from none-extreme) and the function of their joint (scale from none-extreme)

    Pre-operation, 6-weeks post-op, 3-months post-op and 1-year post-op

  • Patient health status - Western Ontario and McMaster Universities Arthritis Index

    This will be done by comparing the Western Ontario and McMaster Universities Arthritis Index (WOMAC) Patient-reported outcome measurement questionnaire given to patients. This survey will ask patients about the pain, stiffness and difficulty of using their knee. This survey is scaled from 0-4, 0 being none and 4 being extreme.

    Pre-operation, 6-weeks post-op, 3-months post-op and 1-year post-op

  • Patient health status - Global Assessment

    This will be done by comparing the UCLA Activity Score (UCLA) Patient-reported outcome measurement questionnaire given to patients. This survey assesses the activity level of patients on a scale from 0 - 10 with 10 being the patient regularly participates in impact sports.

    Pre-operation, 6-weeks post-op, 3-months post-op and 1-year post-op

Secondary Outcomes (1)

  • Health Ecominics

    Pre-operation, 1-3 days post-op, 6-weeks post-op, 3-months post-op

Study Arms (3)

Control

Interventions

This intervention will consist of using the ROSA alongside patient-specific alignment. The knee incision will be the same as the standard of care (medial parapatellar approach).

ROSA PSA Parapatellar Approach

This intervention will consist of using the ROSA alongside patient-specific alignment. The knee incision will be an alternative, quad-sparring, subvastus approach.
