This Instructional Course Lecture reviews primary total knee arthroplasty (TKA) liner options, including cruciate-retaining, posterior stabilized, medial-congruent, and medial-pivot liners. The lecture provides experienced orthopaedic surgeons with information on the evolution, biomechanics, and clinical outcomes of these various implant designs. As the demand for TKA increases and surgical techniques evolve, surgeons must understand the nuanced advantages and limitations of each TKA implant design to optimize patient outcomes. 

At the conclusion of this course learners should be able to:  

• Compare the biomechanical advantages and disadvantages of cruciate-retaining versus posterior stabilized total knee arthroplasty implant designs, focusing on patient outcomes, range of motion, and postoperative stability. 
• Analyze the indications for various types of tibial liners for total knee arthroplasty, such as medial congruent, medial pivot, and varus-valgus constrained designs, to optimize patient-specific outcomes. 
• Evaluate the clinical implications of femoral rollback and its effect on the knee extensor mechanism based on the type of articulation surface design. 
• Discuss the potential complications associated with posterior stabilized designs, including increased wear at the cam-post interface and the risks of post dislocation and tibial post fracture. 
• Apply updated knowledge on total knee arthroplasty implant survivorship and revision rates based on liner type, as reported in national registries, to improve surgical decision making. 
• Assess the role of the posterior cruciate ligament in total knee arthroplasty and decide between retention, sacrifice, or substitution based on patient anatomy and clinical needs. 
• Discuss the influence technologies for total knee arthroplasty may have on liner design selection. 
• Describe the surgical techniques and patient outcomes associated with newer medial stabilized and medial-congruent tibial bearings to enhance stability and satisfaction in patients who undergo total knee arthroplasty.
