Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.

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 various sizes and types of modular femoral components, tibial components, patellar components, and accessories for use in primary and revision applications.
