Fig. 3From: A direct referencing method of the tibial plateau for the posterior tibial slope in medial unicompartmental knee arthroplastyMeasurement of the angles on preoperative, intraoperative, and postoperative lateral knee radiography. Preoperative bony PTS (α) and postoperative implant PTS (β) on a lateral radiograph were measured according to a method previously reported (A, B). On the intraoperative lateral knee radiograph, an angle (γ) between the native bony MTP (m3) and the cartilage MTP (l3) was measured (C)Back to article page
