INTRODUCTION: Ankle osteoarthritis (OA) is a challenging pathology, often requiring surgical treatments. In young patients, joint sparing, biologic procedures would be desirable. Recently, a few reports have described the efficacy of bone marrow stem cells in OA. Considering the good outcomes of one-step bone marrow derived cells transplantation (BMDCT) for osteochondral lesions of the talus (OLT), we applied this procedure for OLT in concomitant ankle OA. MATERIALS AND METHODS: 56 patients, with a mean age of 35.6 years (range 16–50), who suffered from OLT and ankle OA, were treated using BMDCT. All patients were clinically checked using AOFAS score, in the pre-operative setting until the final follow-up of 36 months. Weight-bearing radiographs and MRI evaluation using Mocart score were performed, preoperatively and postoperatively. RESULTS: The whole clinical outcome had a remarkable improvement at 12 months, a further amelioration at 24 months and a lowering trend at 36 months (77.8 ± 18.3). Early OA had better outcomes. 16 patients required another treatment and they were considered failures. Clinical outcome significantly correlates with OA degree, BMI, associate procedures. Radiographs were in line with clinical results. MRI evaluation showed signs of osteochondral repair.

Abstract

INTRODUCTION: Ankle osteoarthritis (OA) is a challenging pathology, often requiring surgical treatments. In young patients, joint sparing, biologic procedures would be desirable. Recently, a few reports have described the efficacy of bone marrow stem cells in OA. Considering the good outcomes of one-step bone marrow derived cells transplantation (BMDCT) for osteochondral lesions of the talus (OLT), we applied this procedure for OLT in concomitant ankle OA. MATERIALS AND METHODS: 56 patients, with a mean age of 35.6 years (range 16–50), who suffered from OLT and ankle OA, were treated using BMDCT. All patients were clinically checked using AOFAS score, in the pre-operative setting until the final follow-up of 36 months. Weight-bearing radiographs and MRI evaluation using Mocart score were performed, preoperatively and postoperatively. RESULTS: The whole clinical outcome had a remarkable improvement at 12 months, a further amelioration at 24 months and a lowering trend at 36 months (77.8 ± 18.3). Early OA had better outcomes. 16 patients required another treatment and they were considered failures. Clinical outcome significantly correlates with OA degree, BMI, associate procedures. Radiographs were in line with clinical results. MRI evaluation showed signs of osteochondral repair.
