About this study
Official title: Platelet-rich Plasma Versus Platelet-rich Plasma Plus Concentrated Insulin-like Growth Factor for Patellar Tendinosis: a Randomized Comparative Trial
The purpose of this study is to compare two different platelet-rich plasma (PRP) injections for patellar tendinosis.
Aim: To perform a randomized, double blinded study comparing the clinical effect of PRP versus PRP + concentrated insulin-like growth factor (IGF) in patients with patellar tendinosis.
Read the detailed description
Introduction/Background:
Patellar tendinosis is a frustrating ailment commonly encountered in sports medicine. Treating this condition continues to be a significant challenge for sports medicine physicians. The tendinosis lesion is characterized by collagen disorganization and increased ground substance. One method of treating this problem is using platelet rich plasma (PRP), which is a concentration of platelets from the patient's own blood that provides a high dose of growth factors aimed at stimulating tendon healing. These injections have been used extensively to treat many tendon disorders including patellar tendinosis. Several studies have demonstrated the safety and efficacy of using PRP to treat patellar tendinosis.
One growth factor that is known to be helpful in tendon healing is insulin-like growth factor (IGF). However, IGF is not found in PRP but rather in the free plasma that is spun off during the PRP processing. This free plasma or platelet poor plasma (PPP) is typically discarded but it is a known source of IGF. We have shown that concentrating PPP in the FDA cleared Plasmax device yields an increased concentration of insulin-like growth factor (IGF). Local IGF injections into the patellar tendon have demonstrated improved tendon healing, but the effect on clinical outcomes has never been studied in a controlled fashion.
Research Design: Double blinded randomized comparative trial.
Detailed Study Procedures: 38 patients will be randomly assigned to a treatment arm. 19 patients will receive platelet rich plasma (PRP) and 19 patients will receive PRP plus concentrated IGF. Patient will be blinded to their treatment, but treatment team will not. PRP will be prepared according to standard sterile procedures out of view of the patient to ensure patients are adequately blinded. The injecting physician will not be blinded to randomization scheme.

Platelet rich plasma plus IGF injection into patellar tendon
| Study group | Role | What they receive |
|---|---|---|
| Platelet Rich Plasma | Active comparator | Procedure will be carried out with excellent sterile technique. 54ml of whole blood will be drawn. 54ml will be processed by centrifugation using the GPS III system (Zimmer Biomet, Warsaw, IN) and 1 ml will undergo a complete blood count (for a baseline comparison to determine the fold increase in platelets). The resultant PRP (5ml) will be injected (after 5ml 1% lidocaine has been injected into the skin for comfort) into the patellar tendon using ultrasound guidance to accurately direct the injection to the site of the tendon abnormality. The patient will rest after the injection for 15 minutes and then be dismissed. Receives: Device: Platelet Rich Plasma |
| Platelet Rich Plasma plus IGF | Active comparator | The PRP preparation and blood draw will be identical to the above. 55ml of whole blood will be drawn (1ml will undergo a CBC and the remaining 54ml will be used to make PRP). In addition to preparing the PRP, the resultant PPP (instead of discarding it) will be placed into the Plasmax device (Zimmer Biomet, Warsaw, IN) and concentrated via a second centrifugation cycle. The plasmax concentrate (concentrated IGF) will be added to the PRP (3ml of PRP + 2ml of plasmax concentrate for a total of 5ml) and then will be injected (after 5ml 1% lidocaine has been injected into the skin for comfort) under ultrasound guidance followed by the same rest period. Receives: Device: Platelet Rich Plasma plus IGF |
What is being measured
The primary outcome is the main question the study is designed to answer.
Victorian Institute of Sport Assessment-patellar Tendon (VISA-P)
Victorian Institute of sport assessment scale for patellar tendinopathy [VISA-P] is a self-administered questionnaire consisting of 8 items; 6 are used to evaluate pain levels or disability in daily activities and specific functional tests and 2 provide information regarding ability to play sport. The maximum score possible is 100 points and represents an asymptomatic athlete who can fully engage in sports. The theoretical minimum is 0 points.
Measured: 6 months
Secondary outcomes (3)
Visual Analog Scale-Pain
The Visual Analog Scale (VAS) measures pain intensity. The VAS consists of a 10cm line, with two end points representing 0 ('no pain') and 10 ('pain as bad as it could possibly be').
Measured: 6 months
Tegner Activity Scale
The Tegner activity scale is a one-item score that grads activity based on work and sports activities on a scale of 0 to 10. Zero represents disability because of knee problems and 10 athlete participating in competitive sports.
Measured: 6 months
Blazina Classification
Classification scale for functional limitations associated with patellar tendinitis. Stage 1: Pain after sports activity, Stage 2: Pain at the beginning of sports activity, disappearing with warm-up and sometimes reappearing with fatigue, Stage 3: Pain at rest and during activity; inability to participate in sports, Stage 4: Rupture of the patellar tendon
Measured: 6 months
