Nonoperative treatment is associated with poor clinical outcomes, especially in the presence of a large ME [59], and exacerbation of OA with a higher incidence of subsequent arthroplasty over 5years of follow-up [60]. Nonanatomical placement of the meniscal allograft>5mm relative to the endogenous meniscus adversely affects the mechanical contacts of the knee, which may affect the allograft's ability to prevent articular cartilage degeneration [16, 124]. This cartilage is the meniscus. Hart et al. Babu J, et al.
