Clinical outcome after 2 years evaluated by the Lysholm score. The score is given for the entire patient cohort compared with patients with posttraumatic and mild degenerative defects (Jaeger-Wirth score < 3) and patients with osteoarthritic defects (Jaeger-Wirth score = 3). The preoperative and follow-up times are as indicated. Scores are presented as medians; the ends of the boxes define the 25th and 75th centiles, and error bars the 10th and 90th centiles. Where indicated (asterisks), differences were statistically significant (p < 0.007) compared with the preoperative situation.
