“…In our study, proprioceptive deficits in both the uninjured and injured knees of ACL-injured patients were observed; this finding has been reported previously in the literature [6,26,28,30]. Roberts et al suggested that aberrant afferent information from the receptors of injured limb might also affect contralateral limb's muscle response [30].…”

“…It seems that there are significant impacts on the detection of a bilateral proprioception deficit; results may vary depending on the external or internal controls used and the proprioceptive tests chosen. It has been reported that bilateral defects may follow a unilateral rupture and contralateral knee may not serve as a reliable control [6,10,26,28,30]. In our study we have established the external control group as well, and bilateral defects were detected in the injured group.…”

The aim of this study is to search if there is any proprioceptive difference between auto and allograft anterior cruciate ligament (ACL) reconstructions, and also to determine if there is any relationship between instrumented anterior knee laxity and proprioception after an ACL reconstruction. The following four groups were constituted for this purpose: group I, control group; group II, autograft reconstructions; group III, allograft reconstructions and group IV, people with injured ACLs. Each group consisted of 20 patients/volunteers. Two subgroups were constituted according to the findings of KT-1,000 laxity testing in group II and III; patients/volunteers found to have a laxity of 3 mm or less were enrolled in the normal subgroup and those with a laxity of more than 3 mm were enrolled in the lax subgroup. Two proprioceptive tests were used: threshold to detect passive motion (TDPM) and joint position sense (JPS) by using Cybex Norm dynamometer. Patients underwent ten tests and the discrepancy in degrees was averaged for ten trials. Comparisons were made to evaluate the proprioceptive differences between groups/subgroups; ANOVA and t test was used for comparisons where appropriate, and the significance was set at P < 0.05. There was a significant difference in degrees between patients with injured ACLs and the other three groups in TDPM evaluations (injured: 1.93 degrees vs. control: 1.03 degrees , autograft: 1.01 degrees , allograft: 0.96 degrees ; P < 0.001). Auto and allograft reconstructions were not different from each other and controls. Allo and autograft ACL reconstructions are not different from each other according to proprioceptive measurements. Also, proprioception is not correlated to postoperative anterior knee laxity; many variables involve joint proprioception and mostly the anterior knee laxity may not be the sole determining element, and a lax ACL still may fulfill some of its afferent arc functions as long as it bridges the femur and tibia.

“…The anterior cruciate ligament (ACL) has documented proprioceptive function [26], and deficiency is known to cause walking difficulty especially when going downhill [18,27]. So the measurement of this task appears appropriate to determine whether functional deficits or advantages exist between procedures that sacrifice or preserve the ACL [16].…”

“…In addition to instability secondary to ligament injury, other factors hastening progression of osteoarthritis include repetitive impingement between the ACL and a narrow intercondylar notch, especially in the presence of intercondylar osteophytes [22,23]. The presence of a lateral thrust during the stance phase of gait in patients with a varus deformity may also lead to attenuation and stretching of the lateral stabilizing structures, ultimately causing an ACL deficiency [14,24,25].…”
