Summary
This study details two challenging total knee arthroplasty (TKA) cases. Solutions involved tibial metal wedge augmentation for bone deficiency and the ROBODOC system for complex deformity correction.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Total knee arthroplasty (TKA) is a common procedure for end-stage knee arthritis.
- Complex cases present unique surgical challenges requiring advanced techniques.
Observation:
- Case 1: Arthritis mutilans with significant tibial bone loss.
- Case 2: Post-traumatic osteoarthritis with severe varus deformity and rotational malalignment.
Findings:
- Successful TKA in Case 1 utilized tibial metal wedge augmentation to address bone deficiency.
- TKA in Case 2 was performed using the ROBODOC surgical system for precise correction of deformity.
Implications:
- Demonstrates the efficacy of specialized techniques in managing complex TKA cases.
- Highlights the role of custom augmentation and robotic assistance in achieving optimal outcomes for challenging knee reconstructions.
