Preoperative Planning in Primary Total Knee Arthroplasty

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering

Background:

• Preoperative planning is essential for primary total knee arthroplasty (TKA).
• Inadequate planning can lead to complications and premature implant failure.
• A comprehensive approach ensures optimal surgical outcomes.

Purpose of the Study:

• To emphasize the critical role of preoperative planning in primary TKA.
• To outline the key components of a thorough preoperative assessment.
• To guide surgeons in selecting appropriate surgical strategies and implants.

Main Methods:

• Detailed patient history collection for appropriate selection.
• Comprehensive physical examination assessing soft tissues, neurovascular status, range of motion, and deformities.
• Standard radiographic imaging (AP, lateral, skyline) for templating bone cuts, implant size, and position.

Main Results:

• Thorough analysis enables surgeons to anticipate challenges and minimize risks.
• Physical examination guides soft-tissue balancing and constraint strategy.
• Radiographic templating optimizes bone preparation and implant placement.

Conclusions:

• Meticulous preoperative planning is fundamental for successful primary TKA.
• A combination of clinical evaluation and imaging is necessary for complex cases.
• Surgeons must be prepared with advanced techniques and implants for challenging reconstructions.
