The optimal
treatment for combined
osteochondritis dissecans (OCD) with considerable bony defect of the lateral femoral
condyle (LFC) and torn discoid
lateral meniscus is unclear. We present a case of a 15-year-old
female who was a gymnast and had a large OCD lesion in the LFC combined with
deficiency of the
lateral meniscus. The
patient underwent the "one-step"
technique of osteoperiosteal autologous
iliac crest graft and
lateral meniscus allograft transplantation after a failure of
meniscectomy with repair at another
hospital. Twenty-four months postoperatively, clinical results were significantly improved. Follow-up imaging tests and second-look
arthroscopy showed well incorporated structured
bone graft and fibrous
cartilage regeneration as well as stabilized
lateral meniscus allograft. She could return to her
sport without any
pain or swelling. This "one-step" surgical
technique is worth considering as a
joint salvage
procedure for massive OCD lesions with torn discoid
lateral meniscus.
