“…The higher participation of the population in sports has resulted in a constantly increasing incidence of ACL tears. The func-tional instability after the rupture can lead to additional meniscal and chondral injuries as well as to the development of degenerative joint disease [9,15,16,22]. Successful treatment must therefore preserve intact meniscal and chondral structures.…”

A prospective, randomised, 5-year follow-up study was designed to compare the functional results between patellar tendon and hamstring tendon autografts after anterior cruciate ligament reconstruction. Primary reconstruction was performed in 32 patients using the central third of the patellar ligament and in 32 patients using double-looped semitendinosus and gracilis tendons. All reconstructions were performed by a single surgeon, with identical surgical technique and rehabilitation protocol. Of the total 64 patients in the study, 54 (85%) were available for the 5-year follow-up. No statistically significant differences were seen with respect to Lysholm score, International Knee Documentation Committee (IKDC) classification, clinical and KT-2000 arthrometer laxity testing, single-legged hop test and anterior knee pain. Graft rupture occurred in two patients (8%) in the patellar tendon group and in two patients (7%) in the hamstring tendon group; 23 patients (88%) in the patellar tendon group and 23 patients (82%) in the hamstring tendon group returned to their pre-injury activity level. Good subjective outcome and stability can be obtained by using either graft; no statistically significant differences were found in functional outcome between the grafts.Résumé Une étude prospective randomisée avec un suivi moyen de 5 ans a été réalisée de façon à comparer les résultats de la reconstruction du ligament croisé antérieur par tendon rotulien ou tendon de la patte d'oie. Cette reconstruction a bénéficié à 32 patients, dans chaque type de traitement. Pour les patients traités par tendons de la patte d'oie on a utilisé à l'aide d'un double renfort le semitendineux et le gracilis. Toutes ces interventions ont été réalisées par le même chirurgien avec la même technique de rééducation. Sur les 64 patients de l'étude, 54 (85%) ont pu être suivis pendant 5 ans. Il n'y a pas de différence significative entre ces deux séries, après analyse selon le score de Lysholm, la classification IKDC, la laxité clinique et la laxité évaluée par le KT-2000. De même en ce qui concerne le sautillement et les douleurs antérieures du genou. Une rupture de la greffe est survenue chez deux patients (8%) du groupe tendon rotulien et chez deux patients (7%) du groupe tendon de la patte d'oie. 23 patients (88%) du groupe tendon rotulien et 23 patients (82%) du groupe patte d'oie ont pu reprendre leurs activités à un niveau identique à celui qu'ils avaient avant l'accident. Ces techniques permettent d'obtenir une bonne stabilité sur le plan résultats subjectifs sans différence significative quelle que soit la greffe utilisée.

“…Disruption of this support mechanism changes the joint kinematics and induces joint instability and osteoarthritic changes [10,17]. However, Kennedy et al [12] reported in 1982 that clinical symptoms characteristic of knees with ACL injury (e.g., giving way, progressive laxity, and early degenerative changes) occur due to the disappearance of mechanoreceptor feedback in addition to altered kinematics.…”

The aim of this study was to investigate the characteristics of proprioception in patients with an anaterior-cruciate-ligament (ACL)-injured knee and to determine whether there is a correlation between proprioception and performance. We studied 32 patients with unilateral isolated ACL ruptures. Proprioception of the knee was evaluated by examining the joint position sense. Functional performance was evaluated with the one-leg hop (OLH) and one-leg vertical jump (OLV) tests. The mean error angle of the joint position sense was 3.6±1.5°o n the intact side and 5.2±1.9°on the injured side. The joint position sense was thus clearly reduced on the injured side (p<0.05). The distance of jumping in the OLH test and the height of jumping in the OLV test was also clearly reduced on the injured side compared with that on the intact side (p<0.01) both with and without visual control. Moreover, we found a significant correlation between proprioception and performance in the ACL-injured knees, and this correlation was more distinct with visual deprivation. In conclusion, decreased proprioception in patients with ACL deficiency reduced their functional ability.Résumé Le but de cette étude était d'étudier les caractéristiques de proprioception chez les malades avec une lésion du LCA, et déterminer s'il y avait une corrélation entre proprioception et performance. Nous avons étudié 32 malades avec une rupture isolée unilatérale du LCA. La proprioception du genou a été évalué en examinant le sens des positions de l'articulation. La fonction a été évaluée avec le saut à cloche-pied (OLH) et saut vertical unipodal (OLV). L'angle moyen d'erreur de position était 3,6±1,5°sur le côté intact et 5,2±1,9°sur le côté blessé. Le sens de position était donc notablement réduit du côté blessé (p<0.05). La distance de saut dans l'épreuve OLH et la hauteur du saut dans l'épreuve OLV ont aussi été réduite du côté blessé comparé avec le côté intact (p<0.01) les deux avec et sans contrôle visuel. De plus, nous avons trouvé une corrélation certaine entre proprioception et performance dans les genoux avec lésion du LCA, et cette corrélation était encore plus nette avec privation visuelle. En conclusion, la diminution de la proprioception chez les malades avec une insuffisance du LCA à réduit leur capacité fonctionnelle.

“…Injury to the ACL often leads to the development of degenerative osteoarthritis (OA) [8,17]. In addition, patients with ACL injury and posttraumatic OA are on average 15-20 years younger than patients with primary OA when they become symptomatic [5,17].…”

We studied the biochemical characteristics of human knees with deficient anterior cruciate ligaments (ACL) and analysed their relationship to the time after ligamentous injury. Thirty-two patients with isolated ACLinjured knees and six healthy volunteers were enrolled. Synovial fluid samples were centrifuged after aspiration during arthroscopic examination, and aliquots of supernatant were frozen and stored at −80°C. The samples were analysed for interleukin (IL)-1β, tumour necrosis factor (TNF)-α, IL-6, matrix metalloproteinase (MMP)-3, and tissue inhibitor of metalloproteinase (TIMP)-1 using commercially available sandwich enzyme-linked immunosorbent assay. In fluid from ACL-injured knees, the average concentrations of IL-6, MMP-3 and TIMP-1 were highly elevated in comparison with normal controls. There was a statistically significant correlation between the concentrations of MMP-3 and IL-6. The IL-6 and TIMP-1 concentrations were interrelated. The concentration of MMP-3 remained high, independent of the duration since the injury, whereas the TIMP-1 and IL-6 levels decreased. The results suggest that the timing of the treatment of an ACL-injured knee might be of importance.Résumé Nous avons étudié les caractéristiques biochimiques des genoux humains avec un ligament croisé antérieur défectueux (LCA) et avons analysé leur rapport au temps après la lésion ligamentaire. Trente-deux malades avec une lésion isolée du LCA et six volontaires sains ont été enrôlés.
