Fig. 3From: The influence of posterior tibial slope on the mid-term clinical effect of medial-pivot knee prosthesisPreoperative/postoperative range of motion (ROM). The postoperative ROM was significantly higher than preoperative ROM in the three groups. There was no significant difference in preoperative ROM between the three groups of patients, and the postoperative ROM of patients in groups B and C were significantly greater than the ROM in group A. In terms of ROM improvement, the effects of surgery on those in group B and group C were better than observed in group A. However, the postoperative ROM of 1 patient in group C was lower than it was before surgeryBack to article page
