Injection is outpatient; patients usually resume gentle activity within 48 hours and structured rehabilitation within 1–2 weeks. Full return to competitive sport typically requires 3–6 months of progressive training, irrespective of cell therapy; the cells themselves do not accelerate training tolerance.
The tendon-injury cell-therapy landscape encompasses 22 completed trials and 1 actively recruiting study. Most involve placental MSC injections or exosome preparations administered directly into the tendon lesion under ultrasound guidance. Trial cohorts typically include both acute partial tears and chronic degenerative tendinopathy. Imaging outcomes (ultrasound, MRI) in small studies show improved fibre continuity and reduced fluid signal in approximately 50–70% of treated tendons. Functional metrics (strength, pain reduction, return-to-activity) vary by trial; some report 60–80% of athletes returning to sport within 6–12 months, though untreated controls are rarely present for comparison.
