We describe the imaging and pathologic features of a case of intratendinous patellar gouty tophus incidentally discovered in a patient with knee pain. The possibility of intratendinous gouty tophus must be kept in mind by sports physicians, especially in the management of patellar tendinopathy in athletes. It may be associated with other injuries, such as enthesopathies or partial tendon tears.

The purpose of this study is to determine if patients with chronic patellar tendinopathy will improve clinically after the inoculation of bone marrow mononuclear cells (BM-MNCs). Eight patients with chronic patellar tendinopathy were included. Patients averaged 24 years old (range 14-35). All patients were refractory to conservative treatment for at least 6 months before the procedure. BM-MNCs ...

PURPOSE The efficacy of platelet-rich plasma (PRP) in the treatment and healing of chronic tendinopathy through stimulation of cell proliferation and total collagen production has been demonstrated by both in vitro and in vivo studies. The aim of this study is to evaluate the effectiveness of ultrasound (US)-guided autologous PRP injections in patellar and Achilles tendinopathy. MATERIALS AND...

Patellar tendinopathy is a common and difficult-to-treat overuse injury of the patellar tendon with a very negative impact on the careers of many athletes. It appears to involve a failed healing process in the tendon – not inflammation – and has consequences for the treatment strategy. Rehabilitation programs are based on the principles of load reduction and an eccentric exercise program to imp...

To investigate how mild symptomatic patellar tendinopathy (PT) affects quadriceps contractions and the Fente motion, this case-control study examined elite fencers who continue to train and play fully with mild tendon pains. Twenty-four elite fencers (10 women) with mild symptomatic PT and 24 controls (10 women) participated in the study. Concentric/eccentric isokinetic strength of the quadrice...

PURPOSE To evaluate whether ultrasound-guided injection of hyperosmolar dextrose for treatment of patellar tendinopathy decreases pain scores and normalises the appearance of the patellar tendon on ultrasound. METHODS Subjects were referred from primary care clinics and failed conservative treatment. Subjects received a diagnostic ultrasound examination, then ultrasound-guided injection of 25...

BACKGROUND Conservative treatment of patellar tendinopathy has been minimally investigated. Effective validated treatment protocols are required. OBJECTIVES To investigate the immediate (12 weeks) and long term (12 months) efficacy of two eccentric exercise programmes for the treatment of patellar tendinopathy. METHODS This was a prospective randomised controlled trial of 17 elite volleybal...

Bilateral patellar tendon ruptures are rare. The majority of case reports describing bilateral patellar tendon ruptures have occurred in patients with predisposing factors to tendinopathy. We describe a case of bilateral patellar tendon rupture sustained following minimal trauma by a patient with no systemic disease or history of steroid use. Due to the rarity of this injury, clinical suspicion...

BACKGROUND Patellar tendinopathy has a high prevalence rate among athletes. Different therapeutic options can be found in the current literature, but none of them has been clearly established as the gold standard. The purpose of this study is to compare, in a randomized controlled trial, the clinical efficacy of eccentric exercise combined with either an ultrasound-guided galvanic electrolysis ...

This review presents current understanding of mechanisms action extracorporeal shockwave therapy (ESWT) and provides a brief overview its history development. The central purpose this is to synthesize research findings investigating the effectiveness ESWT for seven common tendinopathies (plantar heel pain, rotator cuff, lateral elbow, Achilles, gluteal, hamstring patellar tendinopathy) provide ...
