LYON, France — Results of a large, multicenter study with a mean follow-up of 2.3 years presented here illustrated the efficacy of distal femoral osteotomy for patients with varus and valgus knees.
“This is a case series of 108 distal femoral osteotomies at early follow-up demonstrating clinical improvement and satisfaction of eight out of 10,” David W. Elson, MBChB, MRCS, FRCS (T&O), said during his presentation at the International Society for Arthroscopy, Knee Surgery and Orthopaedic Sports Medicine (ISAKOS) Biennial Congress.
Elson and colleagues extracted data for 108 distal femoral osteotomies, of which, four cases were bilateral procedures. Overall, most osteotomies were performed with a medial closing wedge technique, and most were done in men in their fifth decade of life, Elson said. In addition, 97 procedures were done on valgus knees.

Overall, valgus knees were corrected from a mean of 5.3° to a varus angle of 2.3°. In varus knees, the mean lateral distal femoral angle decreased from 93° to 85.1°.
As a combined group, patients’ Oxford Knee Scores improved 10.7 points, KOOS improved 25.1 points and VAS pain scores were reduced by 33.7 points. Additionally, patients rated their satisfaction with the procedure as an eight out of 10.
“But, it is not all good,” Elson said. “We had one case that was converted to an arthroplasty and four cases that were revised. We had complications, which were in 10% of the patients.” – by Gina Brockenbrough, MA
