Knee dislocations: experience at the
Hôpital du Sacré-Coeur de Montréal
Max Talbot, MD;* Greg Berry, MD;† Julio Fernandes, MD;‡ Pierre Ranger, MD‡ Introduction: Although many options exist for ligament reconstruction in knee dislocations, the opti-
mal treatment remains controversial. Allografts and autografts have both been used to reconstruct the
cruciate ligaments. We present the results of reconstruction using artificial ligaments at Hôpital du
Sacré-Coeur in Montréal. Methods: We reviewed the treatment of all patients with knee dislocations
seen between June 1996 and October 1999. The Lysholm score, ACL-quality of life (QoL) questionnaire,
physical examination and Telos instrumented laxity measurement were used to evaluate the results.
Results: Twenty patients (21 knees) participated in the study. The mean (and standard deviation [SD])
Lysholm score was 71.7 (18). Results from the ACL-QoL questionnaire showed a global impairment in
QoL. Mean (and SD) range of motion and flexion were 118° (10.9°) and 2° (2.9°) respectively. Mean
(and SD) radiologic laxity evaluated with Telos for the anterior and posterior cruciate ligaments were
6.1 (5.7) mm and 7.3 (4.5) mm respectively. Conclusions: Knee reconstruction with artificial ligaments
shows promise, but further studies are necessary before it can be recommended for widespread use. This
is the first study to show specifically a severe impairment in QoL in this patient population.
Introduction : Même s’il existe plusieurs possibilités de reconstruction ligamentaire dans les cas de luxa-
tion du genou, le traitement optimal suscite toujours la controverse. On a utilisé à la fois les allogreffes
et les autogreffes pour reconstruire des ligaments croisés. Nous présentons les résultats de reconstruc-
tions au moyen de ligaments artificiels effectuées à l’Hôpital du Sacré-Cœur à Montréal. Méthodes :
Nous avons passé en revue le traitement de tous les patients ayant subi une luxation du genou et qui ont
consulté entre juin 1996 et octobre 1999. On a utilisé le score de Lysholm, le questionnaire sur la quali-
té de vie (QdV) LCA, l’examen physique et la laxité mesurée au Telos pour évaluer les résultats. Résul-
tats : Vingt patients (21 genoux) ont participé à l’étude. Le score médian de Lysholm (et l’écart type
[ET]) s’est établi à 71,7 (18). Les résultats du questionnaire QdV-LCA ont montré un déficit global de
la QdV. L’amplitude médiane (et l’ET) du mouvement et celle de la flexion se sont établies à 118 °
(10,9 °) et 2 ° (2,9 °) respectivement. La laxité radiologique médiane (et l’ET) mesurée au Telos dans le
cas des ligaments croisés antérieur et postérieur s’est établie à 6,1 (5,7) mm et 7,3 (4,5) mm respec-
tivement. Conclusions : La reconstruction de genou au moyen de ligaments artificiels est porteuse de
promesses, mais d’autres études s’imposent avant que l’on puisse en recommander l’application
générale. Il s’agit de la première étude qui montre spécifiquement un déficit grave de la QdV dans cette
population de patients.
