Surgery for ACL deficiency in patients over 50

To compare the outcomes of arthroscopic ACL reconstruction procedure in 20 middle-aged patients (12 men and 8 women) and 20 subjects younger than 30 years (control group) at a minimum post-operative follow-up of 24 months. Pre- and post-operative anterior-posterior laxity was assessed by Lachman test, pivot shift test and KT1000 arthrometer at manual maximum stress. Clinical functional evaluation was assessed according to IKDC Committee (IKDC) subjective knee form, IKDC ligament standard evaluation and Lysholm score. At 2 years, all variables significantly improved in both groups compared to pre-operative values (P < 0.05), with non-significant intergroup difference. When faced with ACL deficiency, physiological age, condition of the knee at the time of examination, life expectancy and activity level are probably more important than chronologic age. In the present study, arthroscopic surgery for the management of ACL tear and secondary lesions provides comparable clinical outcomes in middle-aged patients and in patients aged below 30.
