and recreational athletes, especially those that participate in sports that involve repetitive jumping and landing. The prevalence has been shown to be 2.5-14% in non-elite athletes and as high as 40-50% in elite basketball and volleyball athletes.  Eccentric training has become the standard treatment for chronic tendinopathies, but other treatments are being investigated that try to stimulate tendon regeneration and modulation of tendon pain.  Some studies, but not all, have supported the use of continuous topical glyceryl trinitrate (GTN) via patches in chronic tendinopathies including lateral epicondylosis, non-insertional Achilles tendinopathy, and supraspinatus tendinopathy.  The objective of the study was to assess if continuous topical GTN treatment improved outcomes among patients with chronic patellar tendinopathy compared to placebo, while both groups underwent heavy-load eccentric training. Anterior cruciate ligament (ACL) reconstruction is performed regularly with relatively favorable results.  However, there remains a lack of evidence to predict who will have favorable outcomes and who may have problems after surgery.  Therefore, purpose of this prospective cohort study was to assess the effectiveness single-legged hop tests to predict self-reported knee function 1-year post ACL reconstruction.
