Key: An empty cell indicates that the particular knee rating at the top of the column was not signficantly affected by meniscal and articular surface conditions. ACLR= anterior cruciate ligament reconstruction; ADL = activities of daily living; contra = contralateral; QoL = quality of life; sports/rec = sports and recreation
