“…41,42 On a subjective assessment, 90% of our patients were satisfied with the outcome. 26,43,44 Most had returned to their previous occupation within three months. Three National standard athletes had returned to full sporting activities six months after operation and 56 patients (79%) returned to the same or an even higher level of athletic activity earlier than has been reported in comparative studies.…”

We carried out a prospective study of 71 patients who had undergone reconstruction of the anterior cruciate ligament with the ABC scaffold. Their mean age was 28 years (18 to 50). All had either sub-acute or chronic traumatic deficiency of the ligament. The mean period of follow-up was five years (four to seven). Assessment included the use of the International Knee Documentation Committee score, the modified Lysholm score, the Tegner Activity score, the Knee Injury and Osteoarthritis Outcome score and measurement with the KT-1000 arthrometer. Two patients had mild recurrent synovitis. There were no infections and no failures of the ligament. During the period of study, two patients sustained a traumatic fracture of a femoral condyle. The implants retained their integrity in both cases. All patients returned to their previous or enhanced levels of daily activity by three months after operation and 56 (79%) achieved their pre-injury level of sporting activity by six months. The patients who were competing in National level sports returned to play at one level less after operation than before. The Lysholm score showed that 58% of the patients (41) were excellent, 34% (24) good, and 8% (6) fair, with a mean post-operative score of 93. According to the International Knee Documentation Committee score, 35% of knees (25) were 'normal', 52% (37) 'nearly normal' and 13% (9) 'abnormal'. Complete satisfaction was noted in 90% of patients (64). The development of osteoarthritis and the management of anterior cruciate deficiency associated with laxity of the medial collateral ligament remains uncertain. Our results indicate that in the medium-term, the ABC ligament scaffold is suitable and effective when early and safe return to unrestricted activities is demanded. We acknowledge the current general hostility towards reconstruction of the anterior cruciate ligament with artificial materials following reports of early failure and chronic synovitis associatiated with the production of particulate debris. We did not encounter these problems.

“…While the peak loads during walking might be lower than other activities, the clinical evidence suggest that the cyclic accumulation of damage over many years due to daily walking may be the most relevant to understanding the etiology of OA (Miyazaki et al, 2002; Prodromos et al, 1985). In addition, it has been shown that routine clinical testing (e.g KT-1000) based on non-ambulatory conditions is not predictive of the long term clinical outcomes for ACL injured or reconstructed patients (Hyder et al, 1997; Pollet et al, 2005; Sernert et al, 1999). Thus, it is important to consider the walking mechanics of patients following ACL reconstruction when examining the factors that influence premature knee OA in this population.…”

This study tested the hypotheses that in patients with a successful anterior cruciate ligament (ACL) reconstruction, the internal-external rotation, varus-valgus, and knee flexion position of reconstructed knees would be different from uninjured contralateral knees during walking. Twenty-six subjects with unilateral ACL reconstructions (avg 31 yrs, 1.7 m, 68 kg, 15 female, 24 mo past reconstruction) and no other history of serious lower limb injury walked at a self-selected speed in the gait laboratory, with the uninjured contralateral knee as a matched control. Kinematic measurements of tibiofemoral motion were made using a previously-described point-cluster technique. Repeated-measures ANOVA (α=0.017) was used to compare ACL-reconstructed knees to their contralateral knees at four distinct points during the stance phase of walking. An offset towards external tibial rotation in ACL-reconstructed knees was maintained over all time points (95%CI 2.3±1.3°). Twenty-two out of twenty-six individuals experienced an average external tibial rotation offset throughout stance phase. Varus-valgus rotation and knee flexion were not significantly different between reconstructed and contralateral knees. These findings show that differences in tibial rotation during walking exist in ACL reconstructed knees compared to healthy contralateral knees, providing a potential explanation why these patients are at higher risk of knee osteoarthritis in the long-term.

“…Une limite de cette étude était le faible nombre des effectifs qui a pu méconnaître une différence significative des moyennes même si celles-ci correspondent aux données de la littérature évaluant un système de laximétrie [15][16][17][18]. Les paramètres de comparaison des populations correspondent à ceux de la littérature [13] et les séries étaient statistiquement comparables.…”

“…Bien que validée par les auteurs pour une poussée de 250 N, une erreur de 2,5 mm pourrait donc faussement faire conclure au diagnostic de lésion partielle. Hyder et al [16] avaient retrouvé une différentielle proche de 2,5 mm entre le genou sain et le genou lésé avec le TELOS TM .…”
