BACKGROUND: Variations in formulations used to prepare platelet-rich plasmas (PRPs) result in differences in the cellular composition and biomolecular characteristics. PURPOSE: To evaluate the cellular composition and the cytokine-release kinetics of PRP according to differences in the preparation protocols. STUDY DESIGN: Controlled laboratory study. METHODS: Five preparation procedures were performed for 14 healthy subjects, including 2 manual procedures (single-spin [SS] at 900 g for 5 minutes

OBJECTIVES: This study was conducted to evaluate the cytokine-release kinetics of platelet-rich plasma (PRP) according to different activation protocols. METHODS: Two manual preparation procedures (single-spin (SS) at 900 g for five minutes; double-spin (DS) at 900 g for five minutes and then 1500 g for 15 minutes) were performed for each of 14 healthy subjects. Both preparations were tested for platelet activation by one of three activation protocols: no activation, activation with calcium (Ca)

PURPOSE: The purpose of this study was to compare clinical outcomes after single-bundle anterior cruciate ligament (ACL) reconstruction with a free Achilles tendon allograft using either a transtibial or an anteromedial portal technique and then to quantify the difference in femoral tunnel position between these 2 approaches. This assessment was to be performed with a new method using conventional magnetic resonance imaging (MRI) with a digital imaging system. METHODS: In this prospective random

PURPOSE: An intra-articular corticosteroid injection is considered an effective treatment for idiopathic adhesive capsulitis of the shoulder. This study examined the efficacy of corticosteroid injections for the treatment for adhesive capsulitis in patients with diabetes mellitus. METHODS: Forty-five diabetic patients were randomized into a corticosteroid injection group or non-injection control group and received the same instruction for a home stretching exercise. The corticosteroid group pati
