Satisfactory medium-term outcomes with lateral condylar sliver osteotomy to correct valgus deformity in total knee replacements

Purpose To describe a surgical technique in correcting valgus deformity during total knee replacement and evaluate medium-term clinical outcomes. Methods This was a retrospective consecutive series of total knee replacement for severe valgus deformity of patients who underwent a lateral ligament complex release with a sliver osteotomy of the lateral femoral condyle with a minimum 1-year follow-up and recording objective and patient-reported outcome measures. Results Twenty-three patients (25 knees) were included with median follow-up of 5 years (range 1–15 years) and average age 67.7 years (range 43–87). The primary diagnosis was osteoarthritis in 14 patients (61%) and inflammatory arthritis in 9 patients (39%). At final follow-up, the median mechanical tibiofemoral angle was restored to 4° (range 2–7) compared with a median valgus of 20° (range 13–30) preoperatively. This was statistically significant ( P
