Abstract
Purpose
To investigate the clinical efficacy of arthroscopic repair combined with platelet-rich plasma (PRP) injection for traumatic meniscal tears.Methods
A retrospective cohort study included patients who underwent arthroscopic repair for traumatic meniscal tears between January 2023 and August 2024. Clinical outcomes were evaluated preoperatively and at 6 and 12 months postoperatively using the International Knee Documentation Committee (IKDC) score, Tegner activity scale (Tegner scale), and visual analogue scale (VAS). MRI healing rate, return to sport (RTS) outcomes, and postoperative satisfaction were evaluated. Subgroup analyses were conducted for patients with preoperative bone marrow edema (BME).Results
A total of 96 patients were included (48 per group), with comparable baseline characteristics. At 6 months, the PRP group demonstrated significantly greater improvements in IKDC score, Tegner scale and VAS than the surgery-alone group (p Conclusions
PRP augmentation for traumatic meniscal repair may provide clinically improvements at 6 months postoperatively, including better IKDC score, Tegner scale, and VAS, a higher meniscal healing rate, and facilitate earlier RTS. However, these benefits diminished by 12 months, with functional differences falling below the MCID and no sustained difference in healing rate. Patients with preoperative BME may derive greater functional benefit from adjunctive PRP treatment.
