A large cartilage lesion of the tibial plateau with a deficient meniscus in a young patient is a challenging pathology for the orthopaedic surgeon due to the limited options available. While hemiarthroplasty procedures can be an option, the risk of revision in a young patient is high, and therefore a reconstructive procedure is advocated. The purpose of this Technical Note is to describe our technique for tibial plateau resurfacing, including the preparation and implantation of a medial tibial plateau and medial meniscal allograft, in a patient with a post-traumatic KD-4 knee dislocation with a medial tibial plateau rim fracture, medial meniscus deficiency, and medial tibiofemoral joint subluxation.
