reconstruction of anterior cruciate ligament over 50 years old? yes, or no

Background: the aim of the study is to compare the results of anterior cruciate ligament reconstruction (acl-r) in people aged more than 50 and under 30 years of age. methods: a total of 64 patients with acl rupture were evaluated for eligibility. thirty-two patients with acl rupture, aged more than 50 years (54.38  1.26) were matched in all of the background factors, with 32 patients suffering from acl rupture under 30 years old. they were followed for clinical and functional results at six and on average 45.58 months after surgery. these evaluations included the lachman test, kt-1000, international knee documentation committee (ikdc) score, lysholm knee score (lks), return to exercise activity, post-operative satisfaction rate, and pain intensity based on visual analogue scale (vas) and rates of extension and flexion loss. results: our findings indicated that knee stability, return to exercise activity, lks and ikdc scores, as well as pain intensity and satisfaction were significantly improved in both groups. indeed, the satisfaction rate of patients over 50 years at six months after surgery was less than those under 30 years (p < 0.001); however, it was approximately similar to the group under 30 years of age in the final follow-up (p > 0.05). the rate of return to sports activity was also lower in patients over 50 years. conclusions: the comparable results at the patients with< 30 years demonstrated that arthroscopic acl-r in patients over 50 years of age with no or mild djd has good results.
