Osteochondral Lesions of the Talus Treated With Fresh Talar Allografts

Abstract

Based on these results, we conclude that this is a reasonable procedure for younger adult patients with focal osteochondral talar defects that cannot be corrected with curettage and microfracture.

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

“…Second, owing to the uncommon nature of this condition, we had a limited sample size. Third, the mean length of followup for this study was 3.3 years, which is shorter than in some previous studies [18,20,24,38,45] evaluating fresh osteochondral allograft transplantation for the management of talar OCDs.…”

“…First, as with other allograft studies [18,20,24,27,30,32,37,38,45], we used a prospective cohort design with no control group. A prospective control group was not feasible, as we believe that other treatment options, including total ankle arthroplasty or arthrodesis, would greatly limit function and mobility.…”

“…Studies examining fresh osteochondral allograft transplantation for treating talar OCDs are limited to case series of one to 15 patients [18,20,24,27,32,37,38,45]. Although these studies describe improvement in function, some involved retrospective designs [20,32,37,45], small patient populations [20,32,37,45], multiple conditions such as OCDs, traumatic arthritis, and osteoarthritis [32,45], and limited imaging findings [18,24,32,37,45].…”

Tratamento das lesões osteocondrais do talo através da técnica de microperfurações assistidas por artroscopia

“…Cohen et al (21) also present autologous chondrocyte implantation as a promising technique for chondral lesions of the knee and of the talus. Other authors still advocate the use of mosaicplasty (22) or fresh talus allograft (23) . Gras et al (24) propose the use of navigation in association with arthroscopy aiming to improve the accuracy of the retrograde perforation of cystic osteochondral lesions.…”

Osteochondral lesions of the talus in the athlete: up to date review

“…There are several papers about osteochondral allograft transplantation for the treatment of OLT, and most are small prospective and retrospective case series [74][75][76][77][78][79][80]. El-Rashidy et al [79] performed one of the largest studies in patients who received small cylindrical allografts and reported good or excellent outcomes in 28 of 38 patients at mean 37.7 months of follow-up.…”
