90The purpose of this study is to evaluate the therapeutic benefit of utilizing complex growth factor preparations (Platelet Rich Plasma (PRP) in the management of acute hamstring injuries.
The hypothesis is that the time to return to sport is shorter in the patient group treated with Complex Growth Factor Preparations (PRP) in combination with exercise therapy in comparison with 2 control groups:
the patient group treated with Platelet Poor Plasma (PPP) injections in combination with exercise therapy (control injection AND usual care).
the patient group treated with exercise therapy (usual care)
Placebo: Platelet Poor Plasma Under sterile conditions, patients will receive under ultrasound guidance 3 times, 1 cc injection of PPP each, administered by a sports medicine physician (total 3 cc PPP). Following the completion of the injections (treatment or control) physiotherapy will commence. Physiotherapy protocols will be based on current ASPETAR best practice models (usual care)
Biological: Platelet Rich Plasma Under sterile ultrasound conditions, patients will receive under ultrasound guidance 3 times, 1 cc injection of PRP each, administered by a sports medicine physician (total 3 cc PRP). Following the completion of the injections (treatment or control) physiotherapy will commence. Physiotherapy protocols will be based on current ASPETAR best practice models (usual care)
These patients will not receive an injection. Following the inclusion physiotherapy will commence. Physiotherapy protocols will be based on current ASPETAR best practice models (usual care)
