Riassunto dello studio

Ninety patients with isolated meniscal tears requiring partial meniscectomy were randomized to receive either an intra-articular PRP injection immediately after surgery (n=45) or meniscectomy alone (n=45). The primary outcome was pain reduction assessed using the visual analog scale (VAS) at 30 days. Secondary outcomes included functional recovery measured by the International Knee Documentation Committee (IKDC) subjective score, Knee injury and Osteoarthritis Outcome Score (KOOS) subscales, Tegner score for activity level, and EuroQol-Visual Analog Scale (EQ-VAS) score. Outcomes were assessed at baseline and at 15, 30, 60, and 180 days postoperatively. Overall, the study found no significant differences between groups in pain relief, function, or return to sport. PRP injection led to earlier pain improvement at 15 days, but this advantage did not translate into superior long-term outcomes. These findings suggest that PRP augmentation does not enhance recovery following arthroscopic meniscectomy.
