Summary
Sliding osteotomy of the lateral epicondyle effectively corrects knee valgus deformities in total knee arthroplasty. This procedure demonstrates a safe and fast method for ligament balancing with minimal complications.
Area of Science:
- Orthopedic Surgery
- Biomechanical Engineering
Background:
- Rigid valgus deformity presents a significant challenge in total knee arthroplasty.
- Achieving proper ligament balance is crucial for successful outcomes.
Purpose of the Study:
- To assess the efficacy and safety of lateral epicondyle sliding osteotomy.
- To evaluate its role in correcting rigid valgus deformities during knee arthroplasty.
Main Methods:
- Retrospective analysis of 19 patients undergoing total knee arthroplasty with lateral epicondyle sliding osteotomy (2006-2018).
- Primary endpoint: incidence of complications and adverse events.
- Secondary endpoints: pain (Visual Analog Scale), varus stress, and varus knee thrust during gait.
Main Results:
- No infections or reoperations due to instability were reported in the 19 knees studied.
- Mild to moderate knee pain (VAS 4.6) and mild varus stress were observed in 10.5% of participants.
- No instances of varus thrust were detected post-procedure.
Conclusions:
- Lateral epicondyle sliding osteotomy provides a rapid and safe solution for ligament balancing in knee valgus deformities.
- The technique shows promise for improving functional outcomes in total knee arthroplasty.
