There are limited reports on the effect of platelet-rich plasma (PRP) on meniscus healing. The purpose of this study was to investigate the effect of leukocyte-rich PRP (L-PRP) on potential healing of the horizontal medial meniscus tears in a rabbit model. A horizontal medial meniscus tear was created in both knees of nine skeletally mature adult rabbits. Left or right knees were randomly assig...

Background Platelet-rich plasma (PRP) treatment has gained popularity among different surgical specialities for improving various conditions. Androgenetic alopecia (AGA) is a common disorder, with possible psychosocial implications. Plastic surgeons have increased the practice of PRP injections for hair restoration. A meta-analysis on this topic was performed comparing local injection of PRP ve...

OBJECTIVE To assess whether a platelet-rich plasma (PRP) injection leads to an enhanced tendon structure and neovascularisation, measured with ultrasonographic techniques, in chronic midportion Achilles tendinopathy. DESIGN Double-blind, randomised, placebo-controlled clinical trial. SETTING Sports medical department of The Hague medical centre. PATIENTS 54 patients with chronic midportio...

BACKGROUND We compared the clinical course of rotator cuff tears between rotator cuff exercise and bone marrow aspirate concentration (BMAC)-platelet rich plasma (PRP) injection to identify the therapeutic effects of BMAC-PRP on partial tear of the rotator cuff tendon. METHODS Twenty-four patients with partial tear of the rotator cuff tendon participated in this study. Twelve patients underwe...

To compare the clinical outcome of patients treated with and without platelet-rich plasma (PRP) injection while undergoing arthroscopic labral repair and femoral neck osteoplasty for femoral acetabular impingement. Patients were randomized at the time of surgery to receive either an intra-articular injection of 5 cc of PRP, or an equal volume of 0.9% normal saline. All patients underwent arthro...

BACKGROUND Intratendinous injections may have important effects on the properties of collagen microarchitecture, morphology, and subsequent mechanical properties of the injected tendon. The purpose of this study was to examine the effects of intratendinous PRP injections; the injectant retention within tendons, the distribution of intratendinous injectant, and whether intratendinous injection o...

BACKGROUND Mobilized CD34+ cells in peripheral blood have angiogenic potential, which is an important factor in active hair growth. In addition, activated autologous platelet-rich plasma (PRP) has been reported to induce the proliferation of dermal papilla cells. OBJECTIVES To investigate the clinical efficacy of interfollicular injection of CD34+ cell-containing PRP preparation for pattern h...

BACKGROUND Chronic lateral epicondylar tendinopathy is frequent in athletes, and platelet-rich plasma (PRP) is being used increasingly in its treatment. OBJECTIVE To systematically review the literature on the efficacy of PRP injections for chronic lateral epicondylar tendinopathy. METHODS The databases of PubMed, EMBASE, CINAHL, Medline OvidSP, Scopus, Google Scholar, Web of Science and Co...

Background. Autologous whole blood and platelet-rich plasma (PRP) have been both suggested to treat chronic tennis elbow. The aim of the present study was to compare the effects of PRP versus autologous whole blood local injection in chronic tennis elbow. Methods. Forty patients with tennis elbow were randomly divided into 2 groups. Group 1 was treated with a single injection of 2 mL of autolog...

clinical treatments for patients with TMJ-OA focused only on the relief from orofacial pain caused by progressive de-generation of the articular cartilage. Therefore, as a strategy for maintaining the homeostasis of the synovial joints, recent studies on preventive medicine for OA attempted to shift the metabolic status of the joints from the catabolic to the ana-bolic state using anabolic mate...
