THE EFFICACY OF PLATELET RICH PLASMA IN THE TREATMENT OF PERIARTHRITIS OF SHOULDER JOINT IN DIABETICS VS NON-DIABETICS

Abstract

Periarthritis of shoulder joint / adhesive capsulitis also commonly known as Frozen shoulder, occurs due to adhesion at the glenohumeral joint 1. The term “Frozen Shoulder” was first described in 1934 by Codman.2 The incidence of periarthritis of shoulder joint is around 3-5% in the general population3. It is more common in females4 and develops between the ages of 40 to 70 years3. The main cause of painful restriction of movement in frozen shoulder is an inflammatory contracture of the joint capsule5. A meta-analysis showed that patients with diabetes were 5 times more likely than non-diabetics to have adhesive capsulitis. Also, the overall prevalence of adhesive capsulitis in diabetics was estimated at 13.4%6. According to a population-based followup study, patients with diabetes had an increased risk of developing adhesive capsulitis of shoulder joint as compared to non-diabetics7. The increased incidence of adhesive capsulitis in diabetics might be due to the glycosylation of the collagen within the shoulder joint triggered by the presence of high blood sugar8.
