A Comparative study of steroid injections versus platelet- rich plasma in Rotator cuff Tendinopathies

Abstract

Background: Rotator cuff tendinopathy (RCT) is a main source of disability work inefficiency and overall inefficiency. Platelet-rich plasma (PRP) has been postulated to be of great advantage in the management of RCT. Steroidal formulations are base of all joint morbidities since long for inflammatory and degenerative conditions in orthopedics.
Aim and Objectives: The aim of the study was to compare the effect of PRP injections versus steroid Injection (triamcinolone) in subacromial space on pain control and improved shoulder functions in patients having chronic RCT.
Materials and Methods: The study was conducted on 40 patients (aged more than 18 years) who presented in emergency and Outpatient Department with symptoms of shoulder pain and decreased mobility at shoulder. The patients were divided into two groups. Every odd number of patient presenting to us was given PRP injection (Study group) and every even number patient was given injection triamcinolone (control group) along with physical therapy in both study and control group. Patient was followed up subsequently after 4-week and 12-week time for resolution of symptoms and improved pain-free activities. Outcome assessment criterion used included VAS system and Oxford Shoulder Scoring System.
Results: Comparison of the patients in the two groups revealed significant difference between the groups in VAS and OSS at 4-week and 12-week follow-ups. Long-term effect was more in case of PRP group as compared to steroid formulation which was almost similarly effective acutely.
Conclusion: Subacromial PRP injection was found to be more effective in long-term in improving overall quality of life, disability, pain, improved work efficiency, and improved shoulder movements in patients with chronic RCT than those treated by subacromial steroidal injection along with exercise program.
