Summary
Kinematic alignment in total knee arthroplasty reconstructs patient anatomy for precise motion. This technique minimizes soft tissue balancing but requires careful execution to avoid alignment outliers.
Area of Science:
- Orthopedic Surgery
- Biomechanics
- Surgical Techniques
Context:
- Total knee arthroplasty (TKA) commonly utilizes alignment philosophies.
- Kinematic alignment focuses on replicating prearthritic knee anatomy and motion axes.
- This approach contrasts with traditional alignment methods in TKA.
Purpose:
- To elucidate the fundamental principles of kinematic alignment.
- To differentiate kinematic alignment from alternative TKA alignment strategies.
- To describe the implementation of kinematic alignment in various surgical techniques.
Summary:
- Kinematic alignment reconstructs the native femoral anatomy to restore natural knee joint axes of motion.
- Tibial component alignment is subsequently adapted to the reconstructed femoral component.
- This method aims to minimize the need for extensive soft tissue balancing during TKA.
Impact:
- Provides a foundational understanding of kinematic alignment for orthopedic surgeons.
- Highlights the importance of precise technical execution, recommending calipered techniques to prevent outlier alignment.
- Facilitates informed decision-making regarding TKA alignment strategies.
