Systematic evaluation of the incidence of the knee donor area after autobone cartilage mosaic xentoplasty / 中国骨伤

OBJECTIVE@#To provide an overview of the incidence of knee donor -site morbidity after autologous osteochondral mosaicplasty.@*METHODS@#A comprehensive search was conducted in PubMed, EMbase, Wanfang Medical Network, and CNKI databases from January 2010 to April 20, 2021. Relevant literature was selected based on predefined inclusion and exclusion criteria, and data were evaluated and extracted. The correlation between the number and size of transplanted osteochondral columns and donor-site morbidity was analyzed.@*RESULTS@#A total of 13 literatures were included, comprising a total of 661 patients. Statistical analysis revealed an incidence of knee donor-site morbidity at 8.6% (57/661), with knee pain being the most common complaint, accounting for 4.2%(28/661). There was no significant correlation between the number of osteochondral columns and postoperative donor-site incidence (P=0.424, N=10), nor between the diameter size of osteochondral columns and postoperative donor-site incidence(P=0.699, N=7).@*CONCLUSION@#Autologous osteochondral mosaicplasty is associated with a considerable incidence of knee donor-site morbidity, with knee pain being the most frequent complaint. There is no apparent correlation between donor-site incidence and the number and size of transplanted osteochondral columns. Donors should be informed about the potential risks.

Arthroscopic Treatment for an Osteochondral Lesion of the Talus / 대한정형외과학회잡지

Ankle injury is one of the most common injuries, and osteochondral lesions of the talus occur in up to 70% of acute ankle sprains or fractures. The number of sports injuries have increased due to the increase in leisure activities, and the development of diagnostic techniques to evaluate the cartilage status leads to a higher prevalence of osteochondral lesions of the talus. Although osteochondral lesions of the talus with no symptoms can be treated conservatively, adult patients are usually treated by surgery because they are more likely to fail after non-surgical management. Recovery to normal cartilage is important, but there has been no surgical treatment established for effective cartilage regeneration. Bone marrow stimulation, such as arthroscopic microfracture, is a commonly used surgical procedure and an effective treatment for lesions that are small or failed after non-operative treatment. In addition, there are treatments, such as osteochondral autograft transplantation, osteochondral allograft transplantation and autologous chondrocyte implantation. The selection of the methods depends on the size and location of the lesion, the presence of subchondral cysts, and the results of previous surgery. Many surgical procedures have shown good results in short and mid-term follow-up studies but the results of long-term follow-up have been unclear. Various treatment methods, such as hyaluronan, platelet-rich plasma, mesenchymal stem cells, and bone marrow aspirate concentrate, have been available recently due to the development of various biological agents.

Autologous Osteochondral Transplantation as a Secondary Procedure after Failed Microfracture for Osteochondral Lesion of Talus / 대한족부족관절학회지

Microfracture procedure has been widely recognized as the primary surgical treatment for an osteochondral lesion of the talus. However, if symptoms persist after initial surgery, selection of a secondary procedure can be difficult. The author desciribes the advantage and value of autologous osteochondral transplantation as a secondary procedure after failed microfracture for osteochondral lesion with a review of sevral previous published articles.
