After being informed about the study and potential risks and all participants giving written informed consent, this project will establish a cohort of young men and women who within six weeks have sustained an acute rupture of the ACL. The cohort is randomized into a control and treatment group, where the treatment group receives a zoledronic acid injection at baseline. The cohort will be followed radiographically with high resolution peripheral quantitative computed tomography (HR-pQCT), dual-energy computed tomography (DECT), digital radiography (X-Ray), bi-planar X-ray (EOS) and magnetic resonance imaging (MRI) for eighteen months to monitor the progression of joint changes and the effects of zoledronic acid.
The purpose of this study is to assess if a zoledronic acid injection can alter the trajectory of joint degeneration following an acute anterior cruciate ligament (ACL) injury.
