OBJECTIVE: Assess the long-term results of distal femoral varusing osteotomy and try to establish predictive criteria that could help on selecting patients to be submitted to this technique. METHODS: Fifteen patients with lateral compartment osteoarthritis and valgus deformity of the knee were submitted to distal femoral "V" varusing osteotomy fixated with lateral plate, pursuing knee alignment at 0° on the anatomical axis. The mean follow-up period was 81.4 months, ranging from 43 to 132 months. The Knee Society Rating System protocol was employed. Additional assessed variables were the following: patient age, follow-up time, and postoperative anatomical angle. RESULTS: 11 results were regarded as excellent or good (73%) and four as fair or poor (27%). CONCLUSION: Distal femoral "V" varusing osteotomy constitutes a good treatment alternative for patients with lateral compartment osteoarthritis and valgus knee. The following variables have not been confirmed: patient age at the time of surgery, follow-up time, and postoperative anatomical angle as predictive factors for the results.
