Abstract

Background: Meniscal tears are one of the most frequent injuries to the knee, with an estimated incidence of 222 per 100,000 individuals aged 18 to 55 years based on magnetic resonance imaging. Poor outcomes following meniscal surgical interventions are common and have led many surgeons to use biologic augmentation strategies to enhance the healing. Methods: We conducted a single-center, retrospective, observational study of patients who underwent arthroscopic meniscectomy with and without adjunctive platelet-rich plasma (PRP) or the particulate form of amniotic umbilical cord (AMUC) tissue. We evaluated patient-reported outcomes on the visual analog scale for pain, International Knee Documentation Committee (IKDC) Subjective Knee Evaluation Form, Lysholm Knee Scoring Scale, 12-Item Short Form Survey, and Knee Injury and Osteoarthritis Outcome Score (KOOS) during a 1-year postoperative period. Complications and follow-up procedures were also evaluated. Results: We evaluated 113 patients who underwent meniscectomies from November 2010 to March 2017. Pain severity was significantly decreased only in the AMUC group at 6 months (P=0.0143). Patients in the AMUC group demonstrated significant improvement in functional recovery based on the IKDC and the KOOS subscales of pain, symptoms, activities of daily living, and sport and recreation function at 6 months. Patients in the PRP group had a significant benefit in the KOOS subscales of pain, symptoms, sport and recreation function, and knee-related quality of life at 3 months. Improvement in the control group was less substantial. Patients in the PRP group had more complications and follow-up procedures (30.0%) than patients in the AMUC group (8.3%). Conclusion: In our study population, arthroscopic meniscectomy with adjunctive use of AMUC tissue improved patient-reported outcomes and reduced the reoperation rate compared to conventional technique or adjunctive use of PRP.
