  1. Values in parentheses are those for the group excluding patients who had undergone further operations on the knee. Pain - in the whole group, expectations were met in 44% of patients (values in italics), were not met in 53% (values marked bold), and were exceeded in 3%. Function - in the whole group, expectations were met in 25% of patients (values in italics), were not met in 70% (values marked bold), and were exceeded in 5%. aOne patient had missing data preoperatively, hence n = 111(98).
