# LATERAL EPICONDYLE SLIDING OSTEOTOMY IN KNEE ARTHROPLASTIES WITH VALGUS DEFORMITY

## TL;DR

This study shows that a specific surgical technique can safely correct knee deformities during knee replacement surgery.

## Contribution

The study evaluates the safety and effectiveness of lateral epicondyle sliding osteotomy for valgus deformity in knee arthroplasty.

## Key findings

- No infections or reoperations due to instability were observed in 19 cases.
- 10.5% of participants experienced mild or moderate knee pain post-surgery.
- Sliding osteotomy enabled fast and safe ligament balance for valgus deformities.

## Abstract

Objective: To evaluate the efficacy and safety of sliding osteotomy of the lateral epicondyle in correcting rigid valgus deformity in knee arthroplasty. Methods: A retrospective study of patients undergoing total knee arthroplasty with lateral epicondyle sliding osteotomy between 2006 and 2018. The main outcome was the incidence of complications and adverse events. Secondary outcomes were Visual Analog Scale for Pain, varus stress test, and varus knee thrust during gait. Results: 19 knees (19 participants) were included in the study. The mean follow-up was 4.2 years. There were no cases of infection or reoperation due to instability. Two participants (10.5%) had mild or moderate knee pain (VAS pain = 4.6 ± 1.9). Two arthroplasties (10.5%) had mild varus stress. No participant presented varus thrust. Conclusion: Sliding osteotomy of the lateral epicondyle allows fast and safe ligament balance of knee valgus deformities.
