Subacromial Platelet-Rich Plasma Injections Decrease Pain and Improve Functional Outcomes in Patients With Refractory Rotator Cuff Tendinopathy
Luciano A Rossi et al. Arthroscopy. 2021 Sep.
Methods: Between March & October 2019, 50 patients w/ #rotatorcufftendinopathy refractory to conservative treatment were treated w/ one subacromial PRP injection.
MRI was performed in all patients to confirm diagnosis. Visual analog scale (VAS) used to evaluate pain.
#Rangeofmotion, the #AmericanShoulderandElbowSurgeons #ASESscore, & the #Constantscore were used to assess functional outcomes
80% of patients (40 of 50 patients) & 86% the patients (43 of 50 patients) achieved a clinically significant improvement that exceeded the substantial clinical benefit for the ASES & Constant scores, respectively. Mean (SD) age was 37.3 (9.3) years.
Results: All mobility parameters evaluated improved significantly after treatment. The VAS, ASES, & Constant scores showed statistical improvement after the injection (P < .001). Sleep disturbances (Pittsburgh Sleep Quality Index) were resolved in 86% of patients.
Of the 32 patients who practiced #sports before the injury, 84% returned to sports & 78% returned to the same level.
There were no complications associated with the procedure.
Conclusions: In most patients with refractory rotator cuff tendinopathy, subacromial injections of leukocyte-rich PRP significantly decreased pain, improved functional outcomes, and resolved sleep disturbances. Moreover, most of the athletes returned to sports at the same level they had before the injury.
