Arthroscopy and Micronized Allogenic Cartilage Matrix Grafting for a Missed Talus Nonunion: A Case Report.

CASE: A 33-year-old man who had experienced polytraumatic injury from a motorcycle collision 5 months previously presented to the clinic with right ankle pain. On physical examination, anterior ankle tenderness was present, and imaging revealed a previously unrecognized nondisplaced talar body fracture with a chondral defect. The patient underwent arthroscopy of the right ankle, which influenced the senior author to perform a medial malleolar osteotomy and subsequent open reduction internal fixation with micronized allogenic cartilage matrix.

CONCLUSION

Arthroscopy provides valuable information for the surgical planning of talar nonunions, and allogenic cartilage matrix graft may provide benefit with associated chondral defects.
