Vascularized osteochondral free flaps from the femoral trochlea as versatile procedure for reconstruction of osteochondral lesions of the talus
Osteochondral lesions of the talus (OLT) are defects affecting the articular cartilage as well as the subchondral bone, on the lateral shoulder possibly associated with trauma.

Summary: | Osteochondral lesions of the talus (OLT) are defects affecting the articular cartilage as well as the subchondral bone, on the lateral shoulder possibly associated with trauma. This study presents the results of reconstructing OLT using vascularized osteochondral flaps from the femoral trochlea.
We treated 19 patients with osteochondral talar shoulder defects, using osteochondral flaps from the medial (MFT) or lateral (LFT) femoral trochlea. Functional outcome was evaluated by clinical investigation, visual analogue scale (VAS, 0–10), American Orthopaedic Foot and Ankle Society-Ankle and Hindfoot Scale (AOFAS, 0–100) and The Foot and Ankle Disability Index (FADI, 0–104). Radiographic postoperative follow-up was done by anterior-posterior and lateral X-rays and union of the transferred osteochondral flaps was documented by CT scans.
The osteochondral flaps fused in all of the 19 cases. After a median follow-up of 45.5 months, the patients showed an average FADI of 94.9 and AOFAS-Ankle and Hindfoot Scale of 91.2. All of them were walking free and normal. Subjective median satisfaction was 1.3 in a scale from 1 to 5.
Vascularized transfer of osteochondral flaps from the femoral trochlea is a reliable treatment option for symptomatic OLT of the medial and lateral talar edge.
