The ideal treatment of large full-thickness chondral lesions in the knee, especially "kissing lesions" and osteoarthritis, has not been determined. Microdrilling surgery augmented with injections of peripheral blood stem cells and hyaluronic acid has been used to treat patients with a wide range of articular cartilage disease including patients with bipolar lesions and joint space narrowing. Excellent results in this difficult patient population have been reported, and second-look biopsy has shown repair tissue very similar to native hyaline cartilage...

Platelet-rich plasma (PRP) has been utilized for many years as a regenerative agent capable of inducing vascularization of various tissues using blood-derived growth factors. Despite this, drawbacks mostly related to the additional use of anti-coagulants found in PRP have been shown to inhibit the wound healing process. For these reasons, a novel platelet concentrate has recently been developed with no additives by utilizing lower centrifugation speeds. The purpose of this study was therefore to investigate osteoblast behavior of this novel therapy (injectable-platelet-rich fibrin; i-PRF, 100% natural with no additives) when compared to traditional PRP...

Characteristics of the spreads of platelet-rich plasma (PRP) are not widely known despite commonly use. This study aims to evaluate whether PRP stays within the injected area by using ultrasonography, to improve understanding of the spreads of intratendinous injected PRP. Thirty-nine patients (15 males, 24 females; mean age, 49.3 years), who had symptoms on their elbows (> 6 months) and diagnosed as lateral (25 elbows) or medial (14 elbows) tendinopathies of elbow, were included. The severity of tendon pathology was assessed by ultrasonography as tear or no tear...

BACKGROUND: Rotator cuff tear (RCT) is a frequent condition of clinical relevance that can be managed with a symptomatic conservative treatment, but surgery is often needed. Biological components like leukocytes and platelet rich plasma (L-PRP) could represent an alternative curative method for interstitial RCT. HYPOTHESES: It has been hypothesized that an ultrasound guided L-PRP injection in supraspinatus interstitial RCT could induce radiological healing. MATERIAL AND METHODS: A prospective case series including 25 patients was performed in order to assess the effect of L-PRP infiltration into supraspinatus interstitial RCTs...

BACKGROUND: Platelet rich plasma (PRP) has been used for decades to facilitate surgical tissue repair; therefore, the current trend of percutaneously injecting PRP to theoretically enhance tissue regeneration and repair is a logical progression. Applications include treatment of osteoarthritis, tendinopathy, chondropathy, acute and chronic soft tissue injuries, muscle or ligament tear, as well as enhancement of healing after bone or tissue reconstruction. However, there is limited evidence to support the use of PRP in the abovementioned conditions...

Normal tissue damage following radiotherapy is still a major problem in cancer treatment. Therefore, the current work aimed at exploring the possible role of systemically injected bone marrow derived mesenchymal stem cells (BM-MSCs) and/or locally injected platelet rich plasma (PRP) in ameliorating the side effects of ionizing radiation on the rat's tongue. Twelve rats served as control group (N) and 48 rats received a single radiation dose of 13 Gy to the head and neck region; then, they were equally divided into 4 experimental groups: irradiated only (C), irradiated + MSCs (S), irradiated + (PRP) (P), and combined group (PS)...

BACKGROUND: Chronic tendinopathy is a commonly occurring clinical problem that affects both athletes and inactive middle-aged patients. Although some studies have shown that different platelet-rich plasma (PRP) preparations could exert various therapeutic effects in vitro, the role of leukocytes in PRP has not yet been defined under tendinopathy conditions in vivo. PURPOSE: This study compared the effects of the intratendon delivery of leukocyte-poor PRP (Lp-PRP) versus leukocyte-rich PRP (Lr-PRP) in a rabbit chronic tendinopathy model in vivo...

Background and purpose - In 3 papers in Acta Orthopaedica 10 years ago, we described that platelet-rich plasma (PRP) improves tendon healing in a rat Achilles transection model. Later, we found that microtrauma has similar effects, probably acting via inflammation. This raised the suspicion that the effect ascribed to growth factors within PRP could instead be due to unspecific influences on inflammation. While testing this hypothesis, we noted that the effect seemed to be related to the microbiota. Material and methods - We tried to reproduce our old findings with local injection of PRP 6 h after tendon transection, followed by mechanical testing after 11 days...

BACKGROUND: The tendon is a dynamic entity that remodels permanently. Platelet-rich plasma (PRP) injection has been shown to have a beneficial effect on tendon healing after lesion in rats. Furthermore, eccentric exercise seems to improve the mechanical quality of the tendon. HYPOTHESIS: A combination of PRP injection and eccentric training might be more effective than either treatment alone. STUDY DESIGN: Controlled laboratory study. METHODS: Adult male rats were anesthetized, an incision was performed in the middle of their left patellar tendon and an injection of physiological fluid (PF) or homologous PRP was randomly made at the lesion level...
