Background:Capsulitis of the shoulder joint, also known as adhesive capsulitis or frozen shoulder, is a condition characterized by pain and stiffness in the shoulder joint. The present study was conducted to assess intra articular autologous platelet rich plasma injection in the management of adhesive capsulitis of shoulder joint. Materials & Methods:72 patients with capsulitis of shoulder joint of both genders were administered PRP injection. Patients were followed up for 2 weeks, 4 weeks, 8 weeks and 6 months post injection. DASH, VAS and ROM were recorded. Results: Out of 72 patients, males were 40 and females were 32.DASH score at 2 weeks was 76.2, at 4 weeks was 67.4, at 8 weeks was 46.2 and at 6 months was 20.8. The difference was significant (P< 0.05).VAS at 2 weeks was 6.1, at 4 weeks was 4.2, at 8 weeks was 3.1 and at 6 months was 1.8. The difference was significant (P< 0.05). The mean external rotation (degrees) at 2 weeks was 12.1, at 4 weeks was 23.2, at 8 weeks was 34.5 and at 6 vmonths was 42.6. The mean abduction at 2 weeks was 42.8, at 4 weeks was 68.2, at 8 weeks was 102.5 and at 6 months was 128.6. Internal rotation at 2 weeks was 14.2, at 4 weeks was 21.5, at 8 weeks was 32.7 and at 6 months was 38.4. The difference was significant (P< 0.05). Conclusion: There was significant improvement with PRP in pain in terms of DASH, VAS and functionalROM in patients with adhesive capsulitis.
