Abstract
The purpose of the study was to investigate the effect of combined autologous conditioned plasma and recombinant human collagen type I injections on lateral epicondylitis. Outcome was measured in 5 patients before the single application of ACP+rhCollagen type I (Arthrex ACP® Tendo) and after 10.60±3.58wks by means of (i) the Visual Analogue Scale for pain, (ii) range of motion for wrist extension/flexion as well as supination/pronation, and (iii) MRI-scans. VAS-scores significantly decreased from 6.40±1.14 at baseline to 1.80±2.49 at follow- up, and the effect was very large (p=0.04, dz=2.22). In addition, range of motion either improved or remained unrestricted, and MRI-scans showed healing of the extensor carpi radialis brevis tendon in most cases. A combined ACP+rhCollageninjection successfully reduces pain in lateral epicondylitis. Due to the small sample size, however, these promising preliminary results need further investigation in future research.
