Materials & Methods: 60 grade 1 and grade 2 patients of supraspinatus tendinopathy of both genders. Clinical symptoms, pain, side, history of trauma etc. was recorded. Patients were subjected to USG and MRI of the involved shoulder. PRP was prepared and 2-3 ml of PRP was injected with needle no 24 into site of tendon. Constant Murrey Score was evaluated at baseline, 1 month and 3 months follow up.

Results: Out of 60 patients, males were 43 and females were 17. Side was left in 10% and right in 90%. Etiology was traumatic in 24% and non- traumatic in 76%. Pain intensity was mild in 8%, moderate in 70% and severe in 22%. Investigation for diagnosis was USG in 90% and MRI in 10%. Constant Murrey Score at 0 month was 33.4, at 1 month was 27.5, at 3 months was 21.3, at 6 months was 22.7, at 12 months was 21.4 and at 18 months was 21.1. The difference was significant (P<0.05).

Conclusion: PRP can be considered as treatment modality for supraspinatus tendinitis.
