Evaluation of Navigation-Assisted TKA Using Mechanical vs. Restricted Kinematic Alignment

Официальное название

Evaluation of Navigation-Assisted TKA Using Mechanical vs. Restricted Kinematic Alignment on Patient Reported Outcome Measures (PROMs): A Prospective, Randomized Clinical Study

Обзор

The purpose of this study is to evaluate both clinical measures and PROMs in patients undergoing total knee arthroplasty (TKA) using restricted inverse kinematic alignment (iKA) compared to mechanical alignment (MA), both using surgical navigation assistance.

Подробное описание

A prospective randomized clinical study will be conducted.

The study will consist of two cohorts and will collect clinical data from a maximum of 148 knee arthroplasty surgeries during which the patient will receive the Optetrak Logic® CR TKA device. Cohorts will consist of 1) subjects undergoing MA TKA and 2) subjects undergoing restricted iKA TKA. All cohorts will utilize navigation-assisted surgery (ExactechGPS®) and will be enrolled and consented concurrently. Subjects will be randomized and have a 50% chance of being assigned to the MA TKA cohort and a 50% chance of being assigned to the restricted iKA TKA cohort. Study and research staff will be blinded to randomization and the cohort allocation until after consenting and eligibility is determined. Subjects will be blinded to the randomization (MA TKA or restricted iKA TKA) until the completion of the study.

Data collection under this protocol shall be conducted in a way that conforms to any applicable local and national rules, regulations, and guidelines relating to the conduct of clinical research and the protection of human subjects. As appropriate, this may include but is not limited to the following: Good Clinical Practice (GCP) requirements, FDA regulations and guidelines, ISO 14155: 2020, ICH guidelines, HIPAA and other regulations pertaining to the protection of patient data and data privacy, guidelines established by local Institutional Review Boards or similar Ethics Committees, the Belmont Report, and the Declaration of Helsinki.

• Устройство Optetrak Logic CR Knee System
  The OPTETRAK® Comprehensive Knee System consists of the OPTETRAK® Total Knee System and the OPTETRAK Logic® Total Knee System. The OPTETRAK Comprehensive Knee System comprises both non-porous and porous knee prostheses for use in total-knee joint replacement procedures. (In the USA, the OPTETRAK Comprehensive Knee System is indicated for cemented use only, except for the OPTETRAK Logic PS and CR Porous Femoral Components, which are indicated for cemented or cementless use.) The system includes v
