Summary
Windswept deformity, characterized by one knee in varus and the other in valgus alignment, presents unique challenges for bilateral total knee arthroplasty. Successful surgical outcomes are achievable with careful intraoperative alignment and soft tissue management.
Area of Science:
- Orthopedic Surgery
- Biomechanical Engineering
Background:
- Windswept deformity involves opposing varus and valgus knee alignments.
- This rare condition requires evaluation in patients undergoing bilateral total knee arthroplasty.
Purpose of the Study:
- To investigate preoperative and postoperative differences between varus and valgus knees in patients with windswept deformity.
Main Methods:
- Retrospective analysis of 22 patients with windswept deformity undergoing bilateral total knee arthroplasty.
- Comparison of alignment and joint line positioning between varus and valgus knees.
Main Results:
- Significant preoperative differences noted in overall alignment (P = .0001) and lateral joint line position (P = .0161) between varus and valgus knees.
- No other significant preoperative or postoperative differences were observed between the affected knees.
Conclusions:
- Total knee arthroplasty is a successful treatment for windswept deformity.
- Meticulous intraoperative attention to alignment and soft tissue balancing is crucial for optimal outcomes in both varus and valgus knees.
