Anterior cruciate ligament reconstruction: comparison of male and female athletes using the patellar tendon and hamstring autografts

Few authors have studied the effects of gender on the outcome of ACL reconstruction in athletes. This retrospective-prospective study compared the treating results using the patellar tendon (LP) and hamstring (StG) techniques in men and women. We followed 40 athletes (23 males, 17 females) from population of 120 patients operated at Institute for Orthopaedic Surgery Banjica. There were 13 males and 7 females in the LP group and 11 males and 9 females in the StG group. Patients were operated by the same surgeons within 6 month from injury and underwent the same rehabilitation program. After an average of 24 months they were assesed by clinical evaluation, knee laxity analysis and standard knee scores. Among LP patients there were no significant differences between males and females regarding knee evaluation form, laxity or functional tests. Females in the hamstring group had significantly grater laxity and significantly higher deficit in flexion and extension. We suggest further studies on the clinical significance of these findings, particularly on their ramifications of return to sports and rehabilitation of female athletes.
