According to Fascial Manipulation theory, patellar tendon pain is often due to uncoordinated quadriceps contraction caused by anomalous fascial tension in the thigh. Therefore, the focus of treatment is not the patellar tendon itself, but involves localizing the cause of this incoordination, considered to be within the muscular fascia of the thigh region. Eighteen patients suffering from patell...

PURPOSE OF THE STUDY The aim of this study was to determine the exact localization of the histopathological process (bone, bone-tendon junction or tendon), and to determine whether the underlying pathologic process is predominantly of inflammatory or degenerative nature, then to evaluate the outcome of the surgical treatment of patellar tendinopathy. MATERIALS A prospective cohort study was p...

Patellar tendinopathy (PT) is a clinical and chronic overuse condition of unknown pathogenesis and etiology marked by anterior knee pain typically manifested at the inferior pole of the patella. PT has been referred to as "jumper's knee" since it is particularly common among populations of jumping athletes, such as basketball and volleyball players. Due to its common refractory response to cons...

Study Design Systematic review. Objectives To elucidate if there is sensitization of the nervous system in those with persistent rotator cuff (shoulder), lateral elbow, patellar, and Achilles tendinopathies. Background Tendinopathy can be difficult to treat, and persistent intractable pain and dysfunction are frequent. It is hypothesized that induction or maintenance of persistent pain in tendi...

OBJECTIVE Patellar tendinopathy (PT) is a common and significant clinical condition for which there are few established interventions. One intervention that is currently being used clinically to manage PT symptoms is the introduction of low-intensity pulsed ultrasound (LIPUS). The aim of this study was to investigate the clinical efficacy of LIPUS in the management of PT symptoms. METHODS A r...

BACKGROUND Self-administrated patient outcome scores are increasingly recommended for evaluation of primary outcome in clinical studies. The VISA-P score, developed at the Victorian Institute of Sport Assessment in Melbourne, Australia, is a questionnaire developed for patients with patellar tendinopathy and the patients assess severity of symptoms, function and ability to participate in sport....

BACKGROUND Proximal patellar tendinopathy/jumper's knee (PT/JK) is well known to be difficult to treat. Recent studies using an ultrasound and colour Doppler-based treatment approach on the dorsal side of the tendon, sclerosing polidocanol injections and ultrasound-guided arthroscopic shaving, have shown promising clinical results. OBJECTIVES To compare the clinical effects after treatment wi...

Objective: Expansion of the extracellular matrix is a prominent but poorly characterized feature of tendinosis pathology. We aimed to characterize the extent and distribution of the large aggregating proteoglycan versican in patients with patellar tendinosis. Methods: Tendon was obtained from tendinopathy patients undergoing debridement of the patellar tendon and from controls undergoing intram...

Elevated levels of the neurotransmitter glutamate and the presence of its receptor, N-methyl-d-aspartate receptor type 1 (NMDAR1), have been established in patients with tendinopathy, i.e. chronic tendon pain and degeneration. However, whether NMDAR1 is up- or down-regulated in tendinopathy and co-localized with glutamate is still unexplored. We hypothesize that an alteration in tissue expressi...
