“…They reported a higher failure rate in knees with higher height/sagittal depth ratio, i.e., knees with a rounder femoral condyle [7]. In the current study, lower height/sagittal depth ratio, i.e., knees with a more oval femoral condyle, correlated with a positive GAPS test.…”

Gravity-assisted pivot-shift (GAPS) test is a newly advocated test for anterior cruciate ligament (ACL) injury. It induces anterolateral rotatory instability with valgus stress to the knee applied by gravitational force during patient's active knee motion. We investigated prospectively the relationships between the results of the GAPS test and the possible contributory factors and sought to clarify the determinant factors of the GAPS test. A total of 54 knee joints of 54 patients with unilateral ACL injury (29 males, 25 females, average 23.4 +/- 9.0 years old) were enrolled in this study and were divided into two groups, i.e., positive GAPS test group and negative GAPS test group. Muscle torque around the knee joints measured before surgery, configuration of the femoral condyle and tibial posterior slope angle measured on lateral radiograph, and other clinical factors were compared between the two groups using Mann-Whitney U test or chi-square test. According to the results of these analyses, factors having a statistically significant difference were additionally evaluated using multiple logistic regression analysis to reveal items with strong relevance to a positive GAPS test. The results of the multiple logistic regression analysis showed that the flexor/extensor peak torque ratio of contralateral uninjured knees and sex had a significant correlation with the results of the GAPS test. The relatively less flexor muscle torque compared with extensor muscle torque, and being a female patient were considered to be the determinant factors of a positive GAPS test.

“…Bone 'bruises', sustained at the time of injury, may perhaps damage the subchondral bone (Graf et al 1993;Fowler 1994). Even the geometry of the femoral condyle has been evoked (Friden et al 1993). The mechanical properties of articular cartilage (Setton et al 1994) and changes in synovial fluid cytokines (Cameron et al 1994) have been reported to be influenced by the initial ACL lesion; these changes may help to induce degenerative changes in a reconstructed knee which is subjected to further high-demand activities.…”

The operative treatment of lesions of the anterior cruciate ligament (ACL) in athletes has been widely advocated and performed. We have investigated the outcome of non-operative management in a lowerdemand, general population. We reviewed a consecutive group of 228 patients, which excluded professional and high-level athletes, for two to 12 years after an ACL lesion had been diagnosed by arthroscopy.There was a low incidence of secondary ACL and meniscal surgery, 5.4% and 3.5% respectively, and all these procedures were performed during the first three years after the ACL injury.We studied a subgroup of 109 patients with follow-up of at least five years (mean 8.5 years) and evaluated them using the IKDC score. The general outcome was reasonably satisfactory, with 23% in grade A, 50% in grade B, 21% in grade C and only 6.4% in grade D. We found no statistically significant prognostic effect within this group as regards age, activity levels, or the incidence of associated lesions.J Bone Joint Surg [Br] ] 1996;78-B:446-51. Received 25 August 1995; Accepted after revision 29 November 1995Lesions of the anterior cruciate ligament (ACL) in athletes have been studied extensively in orthopaedic sports medicine, and operative treatment using grafts is widely advocated for this particular group of patients (Fetto and Marshall 1980;Noyes et al 1983a;Kannus and Järvinen 1987;Andersson et al 1989;Barrack et al 1990;Daniel and Fithian 1994). Many ACL lesions, however, are seen in nonathletes as a result of accidents or low-grade recreational activities (Jain, Swanson and Murdoch 1983;Casteleyn, Handelberg and Opdecam 1988). We aimed to investigate the outcome of the conservative treatment of ACL lesions in a lower-demand population. PATIENTS AND METHODSOver a period of 12 years, we managed a total of 274 patients with acute traumatic knee haemarthrosis. All had examination under anaesthesia and arthroscopy.Of these, we treated 46 by ACL reconstruction. They included patients with gross or multidirectional joint laxity (grade-3 or grade-4 pivot shift, combined lesions of the ACL and lateral collateral ligament (LCL) or posterior cruciate ligament (PCL)) and in addition all high-level or professional athletes. These 46 cases (16.8%) were excluded from the study group.This left a consecutive group of 228 patients (83%) who were managed conservatively. There was an almost fourfold male to female ratio and the mean age at the time of injury was 33.2 years (16 to 66). The main causes of injury were daily living activities (28.1%), traffic accidents (11.8%), and recreational activities (60.1%) ( Table I). Initial management. In 83% of the cases, arthroscopic evaluation was within three weeks of the index injury. The proportions of isolated ACL ruptures and those associated with meniscal and ligamentous lesions were comparable with those reported in previous studies (Casteleyn et al 1988) (Tables I and II); only 21 of the ACL tears (9%) were partial. Intrasynovial ACL lesions (14; 6.1%) were left as much as possible within the synov...

“…The spherical shape of the female knee joint, which increases the translation of the joint, may also influence the injury rate (9)(10)(11). Imbalances between strength and mobility of the lower extremities, and intercondylar notch variations may also be risk factors (2,10,(12)(13)(14). The introduction of girls into senior first team games at a younger age than boys results in fewer years of soccer experience (11), which might be another reason for the higher risk of knee injuries.…”
