The purpose of this study was to digitally determine meniscal volumes, and compare them with linear and surface area anthropometric measurements to evaluate these measurements for meniscal allograft sizing. Eighteen subjects (10 male and 8 female; mean age 37.5 years) underwent 3.0 T knee magnetic resonance imaging (MRI) of the dominant leg. The following morphometric measurements were evaluated: medial meniscal volume (MMV), lateral meniscal volume (LMV), tibial plateau width (TPW), width of the femoral condyles (WFC), and tibial plateau surface area (TPSA). MMV and LMV were compared to TPW, WFC, and TPSA. Meniscal volume and TPW were correlated to height and body‐mass index (BMI) and stratified by gender. Statistical analysis included coefficient of determination ( r 2 ) between MRI‐based MMV, LMV, TPW, TPSA, WFC, height, BMI, and gender. Significance was set at the P = 0.05 level. The mean MMV was 2275 mm 3 and the mean LMV was 2102 mm 3 . TPW correlated well with meniscal volumes ( r 2 > 0.62). WFC and TPSA correlated with meniscal volumes in the range of 0.40 < r 2 < 0.61. Height, BMI, and gender correlated poorly with total meniscal volume and TPW with values of r 2 < 0.44. Medial and lateral menisci have statistically similar volumes. TPW had the greatest utility for volumetric meniscal sizing. MRI‐based TPW can be considered as a statistically accurate measurement for determining meniscal volumes and meniscal size. Clin.
