2002 Feb. (395):186-92. 15(3):312-6. J Foot Ankle Surg. The arthroscopic treatment of osteochondral lesions of the talus depends on whether or not the cartilage is intact inside the ankle joint. As this procedure gains favor, more reported complications at the knee donor site may evolve. Studies have shown that excision and nonoperative treatment yield poor results and that excision, curettage, and drilling provide the best outcomes. Surgical treatment of OCLs traditionally includes excision of loose bodies, debridement of the area, and drilling or microfracturing. The CT scan is therefore a valuable diagnostic for preoperative planning. 1959 Sep. 41-A:988-1020. Am J Sports Med.

Treatment strategies in osteochondral defects of the talar dome: a systematic review. incidence 69% of ankle fractures; 70% of ankle sprains; 10% are bilateral Once the diagnosis has been confirmed, treatment may be surgical or non-surgical, depending on the nature of the OLT, presence of other injuries and patient characteristics. De Smet AA, Fisher DR, Burnstein MI. Osteochondral lesions of the talus. Despite the large number of publications (Level II-IV evidence), to date, no strong evidences and guidelines are available in the literature. No mid-term difference in mosaicplasty in previously treated versus previously untreated patients with osteochondral lesions of the talus. Ann Rheum Dis. Success rates for nonoperative treatment with sports restriction and nonsteroidal anti-inflammatory drug or cast immobilization differ from 0% to 100% (review article, In most of the conservatively treated OCL cases, the pain remains untreated and the disease advances to further stages. Drilling can be accomplished by using existing arthroscopic portals, a curved meniscus-repair needle guide, and transmalleolar drill holes. 2010 Dec. 3(6):361-4. Osteochondral lesion of the talus: A radiologic and surgical comparison. Foot Ankle Int. J Bone Joint Surg Br. 2005 Apr. [Medline]. Some have advocated the use of allograft implants, but these grafts may become resorbed over time and fragment, necessitating ankle arthrodesis. However, it can be subdivided into a traumatic and nontraumatic cause. 2009 Oct. 37(10):1974-80. 41(5):1090-9. Chevron-type transmalleolar osteotomy: an approach to medial talar dome lesions.

About 6 months after osteochondral reconstruction, the patient is pain free, has an excellent function, and is back to daily life (job, sports). Hangody L, Kish G, Modis L. Mosaicplasty for the treatment of osteochondritis dissecans of the talus:two to seven year results in 36 patients. 22(5):385-91. .  So far, no reports have been made of allograft rejection by the host. “Osteo” means bone and “chondral” refers to cartilage. Contact characteristics of the anklejoint. 3(7):101-8. 171:13-29. Because of the still unclear natural history of OCLs, several terms can be found for this entity to date in the literature, for example, osteochondritis dissecans, osteochondral fracture, flake fracture, and others. If the lesion is stable (without loose pieces of cartilage or bone), one or more of the following non-surgical treatment options may be considered: 1. incidence 69% of ankle fractures; 70% of ankle sprains; 10% are bilateral The patients, usually of young age (mean age in a meta-analysis on 734 patients, 26.9 years).
