Abstract
Background:Multiple ligament injured knee is generally described for a scenario when at least 2 of the 4 major ligaments are ruptured. The most effective treatment for these injuries remains controversial. This study presents the clinical outcome of 3 surgical strategies based on personalized treatment.Materials and Methods:Thirty two patients with multiple ligament injured knee were treated by 3 surgical strategies in the acute phase. (1) One-stage: Twelve patients treated by repair and reconstruction of all ruptured ligaments in a single operation. (2) Staged: Eleven patients treated by repair or reconstruction of the extraarticular (EA) ligaments and then intraarticular ligaments in 2nd stage. (3) EA ligament repair: Nine patients underwent only EA ligaments repair.Results:The patients were followed up for an average of 34.7 ± 12.1 months. Significant improvements in knee stabilities (P < 0.01), Lysholm score (P < 0.01) and International Knee Documentation Committee grade (P < 0.01) were noticed in all groups. Of the 32 patients, none had gross mal alignment or gait abnormalities at the latest followup. Comparing the 3 groups, a significant difference in Lysholm score was shown between the one stage group and the EA repair group (P = 0.040); additionally, significant differences were found in 2 subscales of knee injury and osteoarthritis outcome score (P < 0.05).Conclusion:Satisfactory clinical and functional outcomes could be achieved adopting the 3 surgical strategies based on personalized treatment. However, a combination of EA repair and intraarticular repair or reconstruction might be more reasonable options for the young and active patients.
