Area of Science:

  • Orthopaedic surgery
  • Biomechanical engineering
  • Surgical technique innovation

Background:

  • Kinematic Alignment (KA) is an alternative surgical technique for total knee arthroplasty (TKA).
  • Restricted KA (rKA) modifies KA to manage extreme anatomies.
  • Standard KA TKA is suitable for most cases, but complex situations require adaptations.

Purpose of the Study:

  • To introduce a classification system for complex KA TKA cases.
  • To guide preoperative recognition and planning for challenging KA TKA.
  • To enhance the reliability of prosthetic implantation and patient outcomes.

Main Methods:

  • Development of a classification system for six specific issues in KA TKA.
  • Inclusion of specific recommendations for each identified situation.
  • Focus on preoperative planning and surgical technique adaptations.

Main Results:

  • The proposed classification system addresses complex KA TKA scenarios.
  • Recommendations aim to improve prosthetic implantation reliability.
  • The system facilitates a common language for improved surgeon communication and teaching.

Conclusions:

  • Complex KA TKA cases require preoperative identification and tailored planning.
  • The classification system aids in managing challenging anatomies and improving surgical consistency.
  • This system can enhance the adoption and teaching of the KA technique in orthopaedics.
