The prevalence of focal cartilage defects in elite athletes is estimated to be as high as 36%, and treatment in professional football players poses a complex clinical challenge. Marrow stimulation is a common treatment option for athletes with symptomatic, contained, full-thickness chondral injuries.
To report the current indications for and efficacy of marrow stimulation in football players.
PubMed, Scopus, and Embase were searched. All levels of evidence (I-IV) pertaining to marrow stimulation in football players were analyzed and presented in a narrative review.
Reported return to sport rates following microfracture range from 52% to 95%, with up to 67% of athletes returning to preinjury level of performance. Clinical outcomes improve shortly after microfracture but may decline by 2 years postoperatively. Augmented marrow stimulation techniques have since been developed in an effort to improve repair quality and clinical outcomes, though supporting data is limited.
In professional football players, marrow stimulation is a viable treatment for the repair of small (<2 cm2), isolated cartilage injuries, though deterioration of mid- to long-term outcomes may hamper its widespread use. Multiple augmentation techniques have demonstrated the potential to generate a mechanically and biologically superior repair; however, more robust, high-level studies are needed to adequately assess efficacy.
