Abstract

Distal femoral medial closing wedge osteotomy (DFMCWO) may be a valuable treatment for arthritic valgus knees in young and active adults, with the possible aim of procrastinating knee replacement.  

32 valgus knees (mean age : 41.4±11.2) treated with DFMCWO were retrospectively reviewed. All the knees had a lateral compartment osteoarthritis graded I-II-III according to Kellgren Lawrence classification. 20 knees had osteochondral le-sions, treated with microfractures (8) or bone marrow derived cells transplantation (12).  Patients were clinically (IKDC, KOOS, NRS, Tegner) and radiologically evaluated. A mean follow-up of 62.12±15.65 was achieved.

KOOS score peaked at 24 months, showed a decremental trend, achieved a final results of 79,59±17,14. Similar trend was evident for IKDC. The final NRS score was 2.73±1.82 ; the final Tegner score was 4.81±1.56. Radiographs showed degen-erative progression in 5 knees : 2 patients underwent knee replacement at the final follow-up.

DFMCWO is an effective treatment to treat osteoarthritic symptomatology, delay degenerative progression and avoid knee replacement in valgus knees at mid-term follow-up
