Individualized surgery in primary total knee arthroplasty.

Area of Science:

• Orthopedic Surgery
• Biomechanical Engineering

Background:

• Total knee arthroplasty (TKA) is a common procedure for end-stage knee joint pathology, but patient dissatisfaction remains a concern.
• Conventional TKA techniques are being challenged by modern approaches emphasizing individual anatomy, alignment, and soft tissue considerations.

Purpose of the Study:

• To present a novel TKA technique that respects individual patient anatomy, laxities, and alignment.
• To evaluate the potential of this technique to improve outcomes in selected patients without relying on advanced technologies.

Main Methods:

• A surgical technique is described that incorporates individual anatomy, soft tissue laxities, and alignment.
• The technique utilizes an implant designed for contemporary knee kinematics.
• This approach does not employ modern technologies like navigation, patient-specific instrumentation, or robotics.

Main Results:

• The presented technique aims to address limitations of conventional TKA and improve patient satisfaction.
• While modern technologies enhance osteotomy accuracy, their long-term impact on TKA outcomes is still under investigation.

Conclusions:

• A TKA technique respecting individual anatomy and kinematics, without advanced technology, is detailed.
• Further research is needed to define the indications, limits, and long-term outcomes of such personalized approaches in TKA.
