The administration of subacromial Platelet Rich Plasma (PRP) injection can be effective for pain relief; improve functional outcomes and sleep in patients with refractory rotator cuff tendinopathy, as learnt from study in ‘Arthroscopy: The Journal of Arthroscopic & Related Surgery‘.Furthermore, many athletes resumed sports at the same level as before.

Luciano A.Rossi et al. aimed to assess the efficacy of PRP injections in terms of pain improvement; functional outcomes; sleep troubles; resume sports activities prior to the injury.

Overall, 50 patients with rotator cuff tendinopathy refractory to conservative therapy were treated with subacromial injection of PRP. Mean follow-up was 1 year.

In case of functional outcomes, clinically notable improvement surpassing the substantial clinical benefit for the American Shoulder and Elbow Surgeons (ASES) score was observed in 80% patients (40 out of 50 patients) and Constant scores in 86 % patients (43 out of 50 patients).

All the mobility parameters assessed improved significantly after PRP injection. There was a significant improvement in visual analogue scale (VAS) for pain assessment. Along with resolution of sleep troubles in majority of patients, 84% resumed sports and 78% returned with the same pace out of 32 patients who performed sports prior to the injury. No complications reported.
