Platelet-rich plasma (PRP) therapy is promising for treating skeletal muscle injuries in human athletes by promoting muscle regeneration. It might also be useful for treating muscle injuries in equine athletes. In the present study, muscle regeneration induced by injection of PRP into intact muscle of Thoroughbred was investigated. Autologous PRP and saline were injected twice into intact left and right gluteus medius muscles of seven clinically healthy Thoroughbreds. Muscle samples were collected from the injection sites by needle biopsy at 2 and 7 days after PRP injection...

BACKGROUND: Insertional Achilles tendinopathy (IAT) represents a serious challenge for both physiatrists and surgeons. Here we analyse the results obtained by two conservative treatments [platelet-rich plasma (PRP) injections and focused extracorporeal shock-wave therapy (ESWT)] in physically active patients with IAT. METHODS: During two consecutive periods, 45 consecutive patients with IAT were treated with 3 sessions of ESWT (2400 impulses at 0.17-0.25 mJ/mm(2) per session) (24 cases between September 2011 and July 2013) or with 2 autologous PRP injections over two weeks (21 cases between September 2013 and July 2015)...

This work describes a technique of platelet-rich plasma (PRP) infiltration for the treatment of severe hip osteoarthritis (OA). Although the results achieved with intra-articular infiltrations of PRP are promising, they may be insufficient in the long-term for severe hip OA. The technique consists of a combined intra-articular and intraosseous infiltration of PRP to reach all joint tissues, especially the subchondral bone, and hence facilitate a greater distribution of PRP. Diagnosis is based on clinical and radiographic findings, and patients with grade III OA according to the Tönnis scale, as well as patients who have not responded to conventional treatment, are considered candidates for this technique...

Carpal tunnel syndrome (CTS) is a common and sometimes challenging condition, which causes pain; paresthesia; tingling of the thumb, index and long fingers; and even thenar weakness in the hands. The effectiveness of corticosteroid injections seems to be transient, and there is a lack of information around long-term effects in previous studies. In recent years, platelet-rich plasma (PRP) has proven to bean alternative as it encourages tissue regeneration. We hereby describe a patient with CTS showing significant improvements in electrophysiological parameters after receiving PRP injections...

EDITORIAL
Larry D Field
The most efficacious treatment for patients with lateral epicondylitis who have not adequately improved despite being treated for extended periods with commonly used nonoperative measures is controversial. Are locally applied platelet-rich plasma (PRP) injections more effective than a surgical procedure, such as arthroscopic lateral epicondylitis debridement, in reducing symptoms for such patients? Level II evidence shows that long-term clinical benefits are much less likely to occur in patients receiving PRP injections...

Platelet rich fibrin (PRF) is a surgical biologic additive that is prepared by manipulation of autologous blood. It has now evolved to become one of the most widely used platelet concentrate in dentistry. It has almost replaced Platelet rich plasma (PRP) for usage owing to its advantages such as being 100% autogenous, easy technique, time and cost effectiveness, superior & prolonged growth factor release. It finds varied applications in dentistry including management of gingival recession, for guided bone regeneration in periodontal, peri-implant and endodontic bone defects...

INTRODUCTION: Elbow epicondylar tendinitis is a common problem for patients whose activities require strong gripping or repetitive wrist movements in the day-to-day activities of life. Histologic specimens from chronic cases confirm that tendinitis is not an acute inflammatory condition but rather a failure of the normal tendon repair mechanism associated with angiofibroblastic degeneration. Tendon regeneration may be improved by injecting autologous growth factors obtained from the patient's own blood...

James H Calandruccio, Murphy M Steiner
Lateral epicondylitis (tennis elbow) is a frequent cause of elbow pain; most patients (80%-90%) are successfully treated with standard nonoperative methods (rest, nonsteroidal anti-inflammatory drugs, bracing, and physical therapy). Autologous blood injections and platelet-rich plasma injections are the two most frequently used orthobiologic techniques in the treatment of lateral epicondylitis. Studies of the effectiveness of autologous blood injections and platelet-rich plasma report varying outcomes, some citing significant clinical relief and others reporting no beneficial effect...
