Structural and Anatomic Restoration of the Anterior Cruciate Ligament Is Associated With Less Cartilage Damage 1 Year After Surgery: Healing Ligament Properties Affect Cartilage Damage
BACKGROUND Abnormal joint motion has been linked to joint arthrosis after anterior cruciate ligament (ACL) reconstruction. However, the relationships between the graft properties (ie, structural and anatomic) and extent of posttraumatic osteoarthritis are not well defined. HYPOTHESES (1) The structural (tensile) and anatomic (area and alignment) properties of the reconstructed graft or repair...
متن کاملRelationships Between Tibiofemoral Contact Forces and Cartilage Morphology at 2 to 3 Years After Single-Bundle Hamstring Anterior Cruciate Ligament Reconstruction and in Healthy Knees
BACKGROUND Prevention of knee osteoarthritis (OA) following anterior cruciate ligament (ACL) rupture and reconstruction is vital. Risk of postreconstruction knee OA is markedly increased by concurrent meniscal injury. It is unclear whether reconstruction results in normal relationships between tibiofemoral contact forces and cartilage morphology and whether meniscal injury modulates these relat...
متن کاملUsing Cine Phase Contrast Magnetic Resonance Imaging to Measuretibial Translation in Anterior Cruciate Ligament Deficient Knees
INTRODUCTION: It is well understood that disruption of the knee’s anterior cruciate ligament (ACL) increases joint laxity in the anterior-posterior (AP) direction. However, the extent to which abnormal tibiofemoral translation occurs during activity remains unclear. Since pathological joint motion has been postulated as a contributor to changes in articular cartilage which may lead to osteoarth...
متن کاملKnee joint proprioception in ACL-deficient knees is related to cartilage injury, laxity and age: a retrospective study of 54 patients.
BACKGROUND ACL-deficient patients have been found to have proprioceptive defects, but the cause of these defects has not been identified nor has the relationship between proprioception and subjective function, laxity, activity level and age been adequately studied. PATIENTS AND METHODS Therefore, we analyzed proprioception, defined as the threshold to detect a slow passive motion (TTDPM), in ...
متن کاملDecrease in anterior knee laxity by electrical stimulation of normal and reconstructed anterior cruciate ligaments.
We have investigated the changes in anterior laxity of the knee in response to direct electrical stimulation of eight normal and 45 reconstructed anterior cruciate ligaments (ACLs). In the latter, the mean time from reconstruction was 26.7 months (24 to 32). The ACL was stimulated electrically using a bipolar electrode probe during arthroscopy. Anterior laxity was examined with the knee flexed ...
