Design outcomes

Primary

MeasureTime frame
The primary objective of this study is to quantify clinical improvement of pain caused by CMC-I osteoarthritis. The comparison is done using a dVAS score for pain (least pain 0-10 most pain). Patients will complete the dVAS score preoperatively and 3 months, 6 months, 9 months, and 12 months postoperative. 

Secondary

MeasureTime frame
The secondary objective of this study is to quantify functional improvement of CMC-I osteoarthritis. The comparison is done using the MHQ-DLV questionnaire. Patients will complete the MHQ-DLV questionnaires preoperatively and 3 months, 6 months, 9 months, and 12 months postoperative. Ultrasound control of the articular space will be performed to inspect signs of synovitis preoperatively, 3 months, 6 months, 9 months, and 12 months postoperative. To quantify functional improvement of CMC-I osteoarthritis by PRP as injectable in comparison to saline, thumb strength and motion will be tested. Strength will be tested with grip strength and pinch test. Motion will be tested with opposition of the thumb (pollexograph) and palmar abduction as well as preoperatively and 3 months, 6 months, 9 months, and 12 months. Data regarding thrombocyte and leukocyte count in blood samples and PRP will be evaluated.
