Background The risk of sustaining a contra-lateral anterior cruciate ligament (C-ACL) injury
after primary unilateral ACL injury is high. C-ACL injury often contributes to a further decline …

Purpose To analyze the correlation between notch width index (NWI) and/or femoral
intercondylar notch width (NW) assessed by magnetic resonance imaging (MRI) and risk of …

Purpose To identify risk factors for patients who sustain nontraumatic anterior cruciate
ligament reconstruction (ACLR) failure. Methods A retrospective analysis was performed on …

Purpose To compare knee anatomical parameters of patients with failed anterior cruciate
ligament reconstruction (ACL-R) with those of a control group of sex-matched patients with …

Background: Altered bone morphologies are considered risk factors for noncontact anterior
cruciate ligament (ACL) injuries. Purpose/Hypothesis: This study aimed to investigate bone …

Background To assess the geometrical risk factors for meniscal injuries. We hypothesized
that the narrowness of the intercondylar notch and the smaller tibial spine could increase the …

Background: Little is known about sex-based differences in anterior cruciate ligament (ACL)
tissue quality in vivo or the association of ACL size (ie, volume) and tissue quality (ie …

Background Stenotic femoral intercondylar notch is considered as a risk factor for anterior
cruciate ligament (ACL) injury and three-dimensional notch volume is used as a marker for …

Background Patellar instability (PI) usually combines with morphological abnormalities of
femoral condyles that may affect the morphology of the intercondylar notch and anterior …

Background Numerous studies have investigated anatomic factors for anterior cruciate
ligament (ACL) injuries, such as posterior tibial slope (PTS) and notch width index (NWI) …
