Patellar tendinopathy is a common cause of knee pain and functional impairment in athletes. It is commonly managed using conservative measures such as physiotherapy, but cases that are refractory to such treatment may require a more invasive approach. Various forms of image-guided injection therapy have been described in the literature. We present a case of successful treatment of chronic patellar tendinopathy with calcification with the first reported use of a three-pronged image-guided approach, consisting of dry needling, high volume image-guided injection (but at a reduced dose) and barbotage applied in a single sitting. The patient reported resolution of symptoms persisting to 1 year postprocedure. We suggest that this management option, if supported by further positive research findings, could be used in the future in the management of certain cases of patellar tendinopathy with calcification where conservative measures have failed.

The mechanism of fibrosis at the patella-patellar tendon junction (PPTJ) was investigated using a rabbit overuse jumping model. Thiry-two female New Zealand White rabbits were randomly divided into control and jumping groups, and each group was further divided into four groups at 2, 4, 6, and 8 weeks. The rabbits in the jumping group jumped 150 times per day, 5 days per week.

Introduction: This study hypothesized that changes in the elasticity of the quadriceps and patellar tendons before and after the diagnosis of patellar tendinopathy would correlate with the range of motion (ROM) following conservative treatment. We aimed to prospectively assess post-treatment ROM using multinomial logistic regression, incorporating elasticity measurements obtained via shear wave elastography (SWE).
Materials And Methods: From March 2023 to April 2024, 95 patients (86 men; aged 20-45 years, mean 25.

Patellar pathologies are a common cause of knee dysfunction, with Patellofemoral Pain Syndrome (PFPS) alone responsible for 25% of knee-related visits to sports medicine clinics. Non-traumatic conditions, while often overlooked, can also lead to significant discomfort and functional limitations, highlighting the importance of accurate and timely diagnosis for effective management and prevention of complications. This pictorial review examines the radiologic characteristics of various non-traumatic patellar disorders, focusing on imaging modalities such as radiography, computed tomography (CT), and magnetic resonance imaging (MRI).

Objectives: Tendinopathy and fasciopathy are common conditions that can result in time-loss injury in athletes. This study aimed to determine if preseason sonographic abnormalities of the patellar tendon, Achilles tendon and plantar fascia are associated with future time-loss injuries in collegiate athletes.
Methods: National Collegiate Athletic Association Division I athletes from three institutions participated in this 3-year prospective, observational study.

Objectives: To investigate whether the effectiveness of progressive tendon loading exercises (PTLE) on patellar tendinopathy is mediated through changes in physical or imaging properties.
Design: Mediation analyses based on a randomized clinical trial (n = 76) in patellar tendinopathy comparing PTLE with eccentric exercise therapy (EET).
Methods: Pain-related disability on Victorian Institute of Sports Assessment-Patella (VISA-P, 0 to 100) and pain (Visual Analogue Score) after single-leg decline squat (VAS-SLDS, 0 to 10) at 24 weeks were outcome measures.
