Injection of autologous conditioned plasma combined with a collagen scaffold may improve the clinical outcome in shoulder impingement syndrome: a prospective study.

Background: Shoulder impingement syndrome (SIS) is one of the most common diseases of the shoulder and can be addressed with various therapeutic concepts. Orthobiological agents such as platelet rich plasma with a low side effect rate gain importance in the conservative treatment of SIS. Currently, the knowledge about success rate influencing factors, such as the growth factors (GF) concentration or acromion type, is limited.

Pain severity reduction in subjects with knee osteoarthritis decreases motor-cognitive dual-task costs.

Background: Pain has disruptive effects on cognitive functions leading to a decreased capability to multi task. This might be the reason why pain is a fall risk factor in dual-task situations. This study aims to relate a decrease/increase in pain severity with a decrease/increase in dual-task costs of gait variability, which is associated with fall risk, in patients with osteoarthritis prior to and 6-8weeks after total knee replacement.

Autologous proliferative therapies in recalcitrant lateral epicondylitis.

Objective: This study investigates the clinical effects of autologous conditioned plasma (ACP) injections and low-level laser application as therapy options for chronic lateral epicondylitis.

Design: A total of 52 patients with chronic lateral epicondylitis were evaluated in this study; 26 of these patients received three ACP injections and the control group, with 26 patients, received 12 laser applications, with standardized physical therapy for all patients afterward. Control examinations took place before treatment, after 2 and 6 mos, and in the 1 yr final follow-up.
