Introduction: Frozen shoulder is marked by discomfort and substantial limitations in both active and passive shoulder mobility. Lundberg divides frozen shoulder into two categories: primary and secondary (based on presence or absence of an inciting event). The majority of the time, there is no underlying sickness (locally or systemically). After a traumatic event or surgery, a secondary condition develops. PRP is a relatively recent therapy option. PRP injections are a type of autologous blood product that aids in the body's natural healing process. Objectives of The Study: After therapy with PRP injection, measure the improvement in pain and mobility in frozen shoulder using the Visual analogue score (VAS) and Quick DASH score. Methods: During the years 2020-2021, this research was carried out at the Department of Orthopedics, Govt Medical College and Associated Group of Hospitals, Kota. Frozen shoulder samples are obtained based on both inclusive and exclusive criteria. Result: The VAS score in this research was 7.40.85 before PRP therapy, however after PRP treatment, the score was 4.9±30.73 after 2 weeks, 2.6±60.60 after 1 month, 0.8±30.69 after 3 months, and 0.1±60.46 after 6 months. Prior to PRP administration, the Quick Dash score was 52.60±6.19, but following PRP therapy, the score was 36.08±6.2 after two weeks, 23.73±5.61 after one month, 10.23±7.2 after three months, and 2.10±3.82 after six months. During each follow-up, the mean score improved consistently, and each score was statistically significant when compared to the prior follow-up. Conclusion: Frozen shoulder is an inflammatory condition that causes significant capsule fibrosis and stiffness in the shoulder joint. The PRP injection uses your own autologous blood to minimize inflammation and speed up the healing process. Faster symptom alleviation reduces long-term morbidity and allows for a quicker return to normal daily activities.
