Research conducted in January-March of 2015.
Summary
Background:
Platelet-rich plasma (PRP) infiltration is a modern treatment for chronic tendon issues, although it remains a topic of debate. Recommendations for enhancement are drawn from documented research and practical knowledge.
Purpose:
Ensuring the accuracy of the PRP collection process is vital. Identifying and addressing risk factors, selecting suitable patients, and guiding post-infiltration recovery are critical. Establishing standards is essential for optimal outcomes.
Key points: platelet-rich plasma, PRP, recovery, enhancement
Additional Information:

It is important to consider the timing of PRP injections in relation to the injury, as this can impact the effectiveness of the treatment. Additionally, proper rehabilitation exercises and physical therapy post-infiltration can aid in maximizing the benefits of PRP therapy. Monitoring patient progress and adjusting treatment plans accordingly can lead to better outcomes in the long run.
Introduction
PRP infiltration accelerates tendon repair by triggering the release of growth factors. However, the quality of PRP can impact the results. Techniques for refining PRP collection and concentration play a key role in successful treatment.
Preparing PRP
The concentration of PRP, devoid of white and red blood cells, is essential for tissue recovery. Pre-infiltration preparation steps, such as fasting and avoiding particular medications, are crucial for effective treatment.
Correcting tendinopathy risk factors
A precise diagnosis and resolution of metabolic factors are necessary before PRP infiltration. Selecting patients who have not responded to traditional therapies for tendon issues is crucial for achieving positive outcomes.
Indications for PRP infiltration
Accurate patient selection and injection methods are crucial for successful PRP treatment of tendon issues. Treating underlying inflammatory conditions is essential for favorable results.
Therapeutic protocol
Utilizing ultrasound for PRP injections in tendon lesions is recommended. Avoiding local anesthesia preserves the therapeutic benefits of PRP. Following the procedure, appropriate rehabilitation facilitates tendon recovery.
Our research on the utilization of PRP for treating jumper’s knee revealed better responses in younger patients due to their enhanced healing capabilities. Patients with jumper’s knee for less than 10.5 months showed the most improvement. Those with superior quadricipital results during contractions demonstrated better progress. Substantial pain reduction within three months signaled positive advancement even after a year. A reassessment at three months determined the need for a second PRP infiltration if partial progress was noted. Performing two closely timed infiltrations is discouraged, and surgery may be considered if no improvement is observed.
For multiple applications, platelet refrigeration or lyophilization may be applied. Freezing and thawing platelets result in platelet lysate, which boosts the growth of mesenchymal stem cells.
PRP Treatment for Chronic Tendinopathies
Standardization is vital for comparing outcomes and advancing knowledge in PRP therapy. Selecting appropriate therapeutic uses and addressing risk factors for tendon problems are essential. Enhancing PRP extraction techniques and injection protocols is key, in addition to post-injection rehabilitation.
