Single-Stage Arthroscopic Minced Cartilage Implantation for Focal Cartilage Defects of the Glenoid Including...

Anterior shoulder dislocations often are associated with cartilage defects of the anterior glenoid (glenolabral articular disruption, or GLAD lesions). However, the importance of GLAD lesions for shoulder stability is usually greatly underestimated. Moreover, glenoid cartilage defects may have a high clinical relevance as the result of persistent pain and possible progression to osteoarthritis. Therefore, surgical treatment appears to be necessary. Although in older patients prosthetic arthroplasty is a useful treatment option for progressive symptomatic cartilage defects, there is still disagreement about the ideal joint-preserving method for the treatment of isolated glenoid cartilage defects, especially in younger and more active patients. In recent years, autologous chondrocyte implantation has been established as a promising treatment option for focal cartilage defects. However, most autologous chondrocyte implantation techniques have the disadvantage of requiring 2 surgical procedures and the availability of specialized laboratories, making the techniques complex and expensive. In contrast, the AutoCart procedure (Arthrex, Munich, Germany) is a cost-effective one-step procedure in which the cartilage defect is filled with a mixture of minced autologous cartilage and autologous conditioned plasma and has already shown good clinical results in the knee joint. We present an arthroscopic technique for use in glenoid cartilage defects.
