Brief Summary:

Osteochondral lesions of the talus are thought to be due in large part to traumatic events or repetitive microtrauma that causes damage to both the articular cartilage and the subchondral bone. There are several treatment modalities for osteochondral lesions of the talus but there is no consensus as to which is the superior method for repair.

Treatment modalities are aimed at regenerating articular cartilage. Microfracture is a widely accepted and utilized treatment for osteochondral lesions. This procedure results in pluripotent bone marrow stem cells filling the defect and ultimately differentiating into fibrocartilage-producing cells [1]. This technique has shown good results in both short- and medium-term follow-up for smaller lesions. Bone marrow aspirate contains mesenchymal stem cells and growth factors with cartilage regeneration potential. Bone marrow aspirate concentrate (BMAC) is a treatment modality that has shown to have to potential to produce hyaline cartilage. This study aims to analyze the effect of adding BMAC to the standard microfracture procedure in terms of clinical and radiographic outcomes in comparison to patients who only underwent microfracture treatment.

Arm Intervention/treatment
Active Comparator: Microfracture Procedure: Microfracture
All surgeons will use a 2 mm microfracture pick to perform the microfracture procedure. Using the 2 mm pick, surgeons will make 5 holes per 10 cm2.

Active Comparator: Microfracture with Bone Marrow Aspirate Concentrate Procedure: Microfracture with Bone Marrow Aspirate Concentrate
Bone Marrow Aspirate Concentrate harvested and prepared from the iliac crest

Primary Outcome Measures :
  1. Foot and Ankle Ability Measure (FAAM) [ Time Frame: 3 years following surgery ]
    validated patient-reported outcome measure
