Isolated Meniscus Tears in Adolescent Patients Treated with Platelet-Rich Plasma Intra-articular Injections: 3-Month Clinical Outcome.

Objectives: Meniscus repair is a challenge for a practitioner, as an injured meniscus can lead to osteoarthritic joint changes with a greatly disabling outcome. Platelet-rich plasma has been regarded as a promising therapy to help induce healing. The purpose of the study is to clinically assess the effectiveness of PRP treatment in adolescents with meniscal lesions.
Methods: This retrospective study analyzed 30 patients with meniscal tears, aged 12 to 17 years, who had documented MRI meniscal lesion and persistent knee pain. In order to evaluate the outcome, the Lysholm knee scoring scale and numerical rating scale were used before injection and 3 months after treatment.
Results: Patients had a mean age of 13.93 years, 70% girls and 30% boys. The most affected was the medial meniscus. The mean value before injection on the numerical rating scale (NRS) of pain was 7.73, after the treatment being of 2.0. After treatment, 76.7% of the patients had "excellent" and "good" outcomes, while before injection, just 3% of the patients had a "good" score.
Conclusions: Platelet-rich plasma treatment can be effective in improving the clinical outcomes of adolescent patients with meniscus tears, for whom conservative management and physical therapy have failed to achieve pain relief.
