Clinical outcomes of hyaluronic acid-sorbitol injection in athletes with patellofemoral pain: Evaluation of the potential influence of body mass index

Elevated body mass index (BMI) may contribute to patellofemoral joint loading, but evidence on hyaluronic acid-sorbitol injection outcomes in athletes with elevated BMI remains limited.
