Secondary surgeries 20 years after surgical and non-surgical treatment of ACL rupture: A population-based cohort study.

Background: Studies with less than 10 years of follow-up have demonstrated no difference between surgical and non-surgical treatment after an anterior cruciate ligament (ACL) rupture; however, long-term effects remain unclear. The aim of this study was to compare the risk of long-term secondary surgical procedures after primary surgical and non-surgical treatment for ACL ruptures.

Methods: Patients aged 18-35, registered in the Danish National Patient Registry with an ACL rupture between January 1, 1996 and December 31, 2000 with a minimum of 20 years follow-up were included.

Does surgery reduce knee osteoarthritis, meniscal injury and subsequent complications compared with non-surgery after ACL rupture with at least 10 years follow-up? A systematic review and meta-analysis.

Objective: We compared long-term follow-up from surgical versus non-surgical treatment of ACL rupture regarding radiographic knee osteoarthritis (OA), secondary surgery, laxity and patient-reported outcome measures (PROMs).

Design: Systematic review and meta-analysis.
