Abstract
the OAT group (p<0.05). MRI evaluation after 5 years demonstrated excellent or good repairs in 94% after OAT compared with 52% after MF. Twenty-six (93%) athletes following OAT and fifteen (52%) athletes following MF returned to sports activities at the pre-injury level at an average of 9.5 months (range 7 to 11 months) after the operations. Twenty-four (86%) athletes following OAT and fifteen (35%) athletes following MF continue to sports activities at the pre-injury level at an average of 5.4 years after the operations. Others showed a decline in the sport activity level. Conclusions: At an average of 5 years (range from 4 to 7 years) follow-up, our prospective, randomized, clinical study in young active athletes under the age of 40 has shown significant superiority of the OAT over microfracture for the repair of articular cartilage defects in the knee. Regarding return to sports, we found that only 35% of MF athletes could continue sports activities at the preinjury level.
