makes interpreting results difficult. Harner et al10 recently published their results in 33 patients treated with repair or reconstruction of all grade III instabilities at a minimum of 24 months of follow-up. Mean Lysholm score was 87 (range, 50 to 100), average Knee Outcome Survey Activities of Daily Living score was 89 (range, 64 to 99), and final overall International Knee Documentation Committee rating was nearly normal for 11 knees, abnormal for 12, and severely abnormal for eight. These results are similar to ones in other published reports.26-28,43-47 Table 56-5 summarizes subjective assessments of operatively treated multiligament-injured knees.
