Hot Topics and Current Controversies in Total Knee Arthroplasty

Area of Science:

• Orthopedic surgery
• Biomechanical engineering

Background:

• Total knee arthroplasty (TKA) is a common procedure for end-stage knee arthritis.
• Continuous advancements in TKA necessitate reviews of current practices and emerging trends.

Purpose of the Study:

• To review current controversies and hot topics in total knee arthroplasty.
• To discuss optimal knee alignment strategies and their evolving debate.

Main Methods:

• Literature review of current controversies and hot topics in TKA.
• Discussion of mechanical, kinematic, and functional alignment strategies.
• Exploration of the role of robotics in TKA.

Main Results:

• Optimal knee alignment strategy remains a subject of debate.
• Robotics, fixation techniques, and outpatient arthroplasty are significant emerging topics.
• Different alignment philosophies (mechanical, kinematic, functional) are being explored.

Conclusions:

• The field of total knee arthroplasty is dynamic, with several key areas under active investigation.
• Understanding these evolving topics is crucial for optimizing patient outcomes in knee replacement surgery.
