摘要
Microfracture is frequently used for articular cartilage repair in athletes. This study aimed to define the strength and weaknesses of this minimally invasive cartilage repair technique in the athletic population in an effort to optimize indications, functional outcome, and athletic participation after microfracture in the athlete's knee. A systematic analysis of original studies using microfracture in athletes was performed. Functional outcome was assessed by activity outcome scores, ability to return to sports participation, timing of the return to sport, level of postoperative sports activity, and continuation of athletic competition over time. Thirteen studies describing 821 athletes were included in the analysis with an average follow-up of 42 months. Good or excellent results were reported in 67% of athletes with normal International Knee Documentation Committee (IKDC) scores in 80% and significant increase of Lysholm scores, Tegner activity scores, and Knee injury and Osteoarthritis Outcome Score (KOOS) sports subscales. Return to sports was achieved in 66% at an average of 8 months after surgery, with return to competition at the preinjury level in 67%. Forty-nine percent of athletes continued to compete without change in level of play, while decreasing function was observed in 42% after 2 to 5 years. Athlete's age, preoperative duration of symptoms, level of play, lesion size, and repair tissue morphology affected sports activity after microfracture. Microfracture improves knee function and frequently allows for return to sports at the preinjury level, but deterioration of athletic function occurs in some patients. Several independent factors were identified that can help to optimize the return to athletic competition after microfracture in the athlete's knee.
