Summary
Achieving proper alignment in total knee arthroplasty requires integrated soft tissue balancing and precise bone cuts. Addressing bony deformities necessitates comprehensive soft tissue management for stable, symmetric knee function.
Area of Science:
- Orthopedic Surgery
- Biomechanical Engineering
Background:
- Total knee arthroplasty (TKA) success relies on accurate correction of knee joint malalignment.
- Malalignment often involves complex bony deformities requiring simultaneous soft tissue management.
Purpose of the Study:
- To emphasize the integrated nature of soft tissue balancing and bone cuts in TKA.
- To highlight the importance of pre-operative planning for bone resection and soft tissue management.
Main Methods:
- Pre-operative planning of bone stock resection.
- Systematic soft tissue balancing, focusing on lengthening contracted structures.
- Achieving equal ligament tension and joint gap height in extension and flexion.
- Femoral resection aligned with the Insall-Line (3-5 degrees external rotation).
Main Results:
- Integrated approach ensures stability of the corrected knee.
- Symmetric flexion and extension gaps are achieved.
- Ligamentous stability is maintained throughout the range of motion.
Conclusions:
- Soft tissue balancing and bone cuts are interdependent and crucial for TKA outcomes.
- Proper management of soft tissues and bone resection leads to improved functional stability and symmetric joint gaps.
