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.

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.

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.

Article Synopsis
  • Patellar tendinopathy is a common type of knee pain in athletes, especially those involved in jumping and running sports, caused by repetitive microtrauma and poor healing at the knee joint.
  • Eccentric exercises can help, but recovery may be slow; thus, there's increasing interest in treatments like platelet-rich plasma (PRP) injections, which have shown effective results with minimal side effects.
  • While PRP therapy displays potential for long-lasting improvement, variations in treatment protocols highlight the necessity for further research to standardize its application, and stem cell therapy also shows promise but lacks sufficient data for widespread recommendation.

Transl Sports Med

June 2024

Nicholas Institute of Sports Medicine and Athletic Trauma, Lenox Hill Hospital, Northwell Health, MEETH a Division of Lenox Hill Hospital, 210 East 64 Street, New York, NY 10065, USA.

Article Synopsis
  • The study examined how different countermovement jump (CMJ) depths affect performance metrics like jump height, muscle activation, and motion analysis.
  • It tested three variations of CMJs: self-selected depth, shallow (15% less), and deep (15% more), involving ten healthy male participants.
  • Results indicated that shallow CMJs significantly reduced jump height by 8% compared to self-selected CMJs, and differences in muscle activation were noted, particularly with the vastus lateralis muscle during the unweighting phase.

Article Synopsis
  • - Patellar tendinopathy (PT) leads to knee pain and limited function, and a study investigated the effects of combining tendon debridement with platelet-rich fibrin matrix (PRFM) therapy on patient recovery and return to sports over 24 months.
  • - The study used various scoring methods to assess treatment effectiveness and found significant improvements in clinical scores post-surgery, with 92.10% of patients returning to sports and high patient satisfaction ratings.
  • - Findings suggest that the combination of surgical debridement and PRFM therapy is more effective than surgery alone, leading to better recovery, increased return rates to sports, and high levels of patient satisfaction at the 24-month mark.

Article Synopsis
  • Previous research showed that patients treated with bone marrow-derived mesenchymal stem cells (BM-MSCs) had better tendon structure and regeneration compared to those treated with leukocyte-poor platelet-rich plasma (Lp-PRP) at the 6-month mark.
  • A follow-up study evaluated 20 patients' outcomes at 12 months after BM-MSC treatment, including those who switched from Lp-PRP to BM-MSCs, to assess any potential benefits of the initial treatment.

Article Synopsis
  • Patellar tendinopathy (PT) is a common injury among volleyball players, potentially exacerbated by overload during intense jumping activities, but its link to fatigue while spiking is unclear.
  • A study with 43 male volleyball players measured how fatigue from a high-intensity jumping protocol impacted patellar tendon loading and movement mechanics before and after exercise.
  • Results showed that fatigue led to a stiffer landing strategy and reduced forces on the patellar tendon, suggesting players may adapt their movements to protect against injury when tired, which could increase the risk of developing PT if those protective adaptations fail after intense play.
