The purpose of this study was to examine the establishment of a model concerned with osteoarthritis resulting from the anterior cruciate ligament rupture of rats and investigate the associated mechanism, as well as provide a theoretical basis for clinical treatment of the disease. Forty Sprague-Dawley male rats were randomly divided into two groups of 20 rats each and the anterior cruciate liga...

BACKGROUND Female athletes suffer a greater incidence of anterior cruciate ligament tears compared with male athletes when participating in common sports; however, very little is known about the factors that explain this disparity. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS Female recreational alpine skiers with an anterior cruciate ligament rupture and age-matched contr...

In this paper a new navigation system, KIN-Nav, developed for research and used during 80 anterior cruciate ligament (ACL) reconstructions is described. KIN-Nav is a user-friendly navigation system for flexible intraoperative acquisitions of anatomical and kinematic data, suitable for validation of biomechanical hypotheses. It performs real-time quantitative evaluation of antero-posterior, inte...

BACKGROUND Up to two-thirds of athletes may not return to their preinjury level of sport by 12 months after anterior cruciate ligament (ACL) reconstruction surgery, despite being physically recovered. This has led to questions about what other factors may influence return to sport. PURPOSE To determine whether psychological factors predicted return to preinjury level of sport by 12 months aft...

OBJECTIVE To test an intra-articular reconstruction of the anterior cruciate ligament of the knee in 10 human cadavers by replacing 2 anterior cruciate ligament bundles, with the purpose of producing a surrogate that would be structurally more similar to the anatomy of the anterior cruciate ligament and would provide the knee with more stability. METHODS We reconstructed the anteromedial and ...

The aim was to explore patients' experiences of the rehabilitation process after anterior cruciate ligament (ACL) reconstruction. Ten participants were enrolled in the study. Semi-structured interviews were performed, focusing on challenges during the post-operative rehabilitation to 1 year after ACL reconstruction. The participants perceived no real choice between operative and non-operative t...

BACKGROUND The reasons behind the development of future pathology in individuals with anterior cruciate ligament deficiency are unknown. This is due to the lack of appropriate methods to assess functional dynamic knee stability. In this study, we investigated the effect of walking speed on the functional dynamic stability of the anterior cruciate ligament deficient knee. We defined functional d...
