Current Concept Review: Osteochondral Lesions of the Talus

Does Fresh Osteochondral Allograft Transplantation of Talar Osteochondral Defects Improve Function?

“…MRI was used to address previously reported limitations of radiography, including low sensitivity, an inability to quantify lesion extent, and inability to evaluate articular cartilage integrity [2,31,33,36,42]. The disparity in detection capabilities between radiography and MRI in the current series (Fig.…”

Allografts in Foot and Ankle Surgery

“…Those series showed similar rates of secondary procedures and graft failure. However, there remains a lack of long-term data regarding the outcome of these procedures, and the literature is limited to small, retrospective case series 20 . It also should be noted that many of those studies utilized the AOFAS Ankle-Hindfoot Scale, which is not a validated instrument, as a key outcome measure 11 ; as a consequence, the improvements should be interpreted with caution.…”

“…It also should be noted that many of those studies utilized the AOFAS Ankle-Hindfoot Scale, which is not a validated instrument, as a key outcome measure 11 ; as a consequence, the improvements should be interpreted with caution. Those Level-IV studies do not provide sufficient evidence (Grade-C recommendation) (Table II) to conclusively support the use of osteochondral allograft for the treatment of an osteochondral lesion of the talus of any size, location, grade, stability, displacement, or containment, or for the use of bipolar tibiotalar allografting 20 .…”

Osteochondral Lesions of Major Joints

“…Osteochondral lesion may also involve the talar dome ( Figure 5), most frequently the medial aspect. It is relatively prevalent and are an important cause of ankle morbidity [27].…”
