Platelet-rich plasma treatment for patellar, Achilles, elbow (epicondylitis), and plantar heel tendinopathies.

Multicenter Real-World Evidence (RWE) Study: Evaluation of Platelet-Rich Plasma (PRP) Treatment in Tendinopathies

Observational ReSport Clinic · NCT07558564

This multicenter observational project will try platelet-rich plasma (PRP) injections to see if they reduce pain and improve function in adults with chronic patellar, Achilles, lateral elbow (epicondylitis), or plantar heel (fasciitis) tendinopathies.

What this trial studies

This is a prospective, multicenter, real-world evidence cohort collecting data on PRP treatment for four common tendinopathies. Participating centers will record clinical variables, treatment protocols, and outcomes over 12 months while characterizing PRP preparations using hematology analyzers and the BioSmartData® platform. The design is observational, so treatments follow routine clinical practice rather than a randomized protocol. Adults with chronic (>6 weeks) tendon symptoms who can consent and complete follow-up are eligible, while recent surgery, recent corticosteroid injection, systemic inflammatory disease, coagulopathy/anticoagulant use, low platelet counts, pregnancy, or breastfeeding are exclusions.

Who should consider this trial

Good fit: Adults (age >18) with a clinical or ultrasound diagnosis of chronic patellar, Achilles, lateral epicondylitis, or plantar fasciitis who can give informed consent and complete 12 months of follow-up and have a platelet count ≥100 × 10⁹/L.

Not a fit: Patients with recent tendon surgery, corticosteroid injection within the last month, systemic inflammatory disease, coagulopathy or anticoagulant therapy, low platelet counts, or who are pregnant or breastfeeding are excluded and unlikely to receive benefit under this protocol.

Why it matters

Potential benefit: If successful, PRP could offer a minimally invasive option that reduces pain and improves function for people with chronic tendinopathies.

How similar studies have performed: Previous randomized trials and meta-analyses report mixed results for PRP in tendinopathies, with some positive findings for lateral epicondylitis and plantar fasciitis but inconsistent outcomes for Achilles and patellar tendons.
