Brief summary

Title Autologous Protein Solution (APS) – the Biological symptom management of HIP osteoarthritis. The hypothesis of this study is that a single injection of APS (nSTRIDE, Zimmer Biomet USA) a product derived from the participant's own blood, is safe and leads to a reduction in hip pain and an improvement in hip function at 3 months which is sustained at 12 months. This will be tested in 10 participants aged over 40 years with painful hip osteoarthritis and mild to moderately severe structural change on x-rays.

Interventions

Preparation of the APS is according to the manufacturers instructions - 55 mls of blood is collected in a tube with 5 mls of anti-coagulant. This is centrifuged for 15 minutes at 3200 rpm. 6 mls of PRP is then transferred to the APS cannister and centrifuged again for 2 minutes at 2000 rpm. the resultant APS is a single 3 ml dose. A single 3 ml injection of Autologous Protein Solution into the hip joint under ultrasound guidance according to standard hip protocols and an aseptic technique. This

A single 3 ml injection of Autologous Protein Solution into the hip joint under ultrasound guidance according to standard hip protocols and an aseptic technique. This is done by an experienced Sport and Exercise Medicine Physician or radiologist. A second sample of APS is prepared at the same time and sent to the laboratory for growth factor analysis
