Patellar tendinopathy, or Jumper's knee, is a painful knee condition caused by inflammation of the patella tendon. This condition is most frequently observed in subjects who play sports that require repetitive regular jumping. Jumper's knee is frequently misdiagnosed as a minor injury and many athletes, like our patient, keep on training and competing and either tend to ignore the injury or attempt to treat it themselves. However, jumper's knee is a serious condition that requires a correct and timely diagnosis, which often necessitates ultrasound investigation in order to start the most appropriate treatment.

A comparative analysis of platelet-rich plasma alone versus combined with extracorporeal shockwave therapy in athletes with patellar tendinopathy and knee pain: a randomized controlled trial.

Article Synopsis
- Patellar tendinopathy, or jumper's knee, is a painful condition affecting athletes, prompting a study to evaluate the effectiveness of platelet-rich plasma (PRP) treatments alone and combined with extracorporeal shockwave therapy (ESWT).
- The study involved 33 athletes randomly assigned to receive either PRP with sham treatment or PRP plus ESWT, with follow-ups over a year to assess pain reduction and functional improvements.
- Results indicated that combining PRP with ESWT led to quicker pain relief and improved outcomes without causing discomfort or injury, supporting its effectiveness for treating chronic patellar tendinopathy in athletes.
Patellar tendon-Hoffa fat pad interface: From anatomy to high-resolution ultrasound imaging.

Department of Physical and Rehabilitation Medicine, Hacettepe University Medical School, Ankara, Turkey.
Aim: To propose a standardized, high-resolution ultrasound (US) protocol to assess the patellar tendon-Hoffa fat pad interface (PTHFPI) in patients with (proximal) patellar tendinopathy (PPT).
Methods: Using a high-frequency transducer and a high-level machine, we matched the cadaveric and histological microarchitecture of the PTHFPI with multiple sonographic patterns of patients with PPT. Likewise, high-sensitive color/power Doppler assessments were also performed to evaluate the microcirculation of the soft tissues beneath the patellar tendon.

Hypoechoic ultrasonographic findings in the patellar ligaments are common in riding and trotting horses in training (116 cases).

Article Synopsis
- A study assessed the ultrasonographic appearance of the patellar ligaments (PLs) and infrapatellar fat pad in 116 horses during training, along with their movement patterns.
- The researchers found that distinct or diffuse hypoechoic areas were common in the intermediate PL, particularly in the caudal mid-third region, while most fat pads appeared hypoechoic except for one case.
- No direct link was found between abnormal ultrasonographic results and lameness, highlighting the importance of considering biological variation in PLs and the need for local analgesia to pinpoint lameness accurately.
