The rate of subsequent surgery and predictors after anterior cruciate ligament reconstruction: two- and 6-year follow-up results from a multicenter cohort.
After an Anterior Cruciate Ligament Reconstruction (ACLR) an extensive rehabilitation is required. Subsequent surgery to either the ipsilateral or controlateral knee is not an exception. This prospective cohort study of almost one thousand participants describes the rates and risk factors of subsequent injuries at short-term (2 years after surgery) and long-term (6 years after surgery).
After a follow-up of 6 years, 18.9 percent underwent at least one subsequent surgery at the ipsilateral knee. About 10.2 percent underwent a surgery at the contralateral knee. The surgery at the ipsilateral knee consisted of revision ACLR (7.7%) and medial (5.7%) and laterals (3.7%) meniscus procedures. The surgeries at the contralateral side were mainly primary ACLR (6.4%) and medial (4.0%) and lateral (2.7%) meniscus procedures. Risk factors for subsequent surgery were younger age at the ACLR surgery and the use of an allograft > From Hettrich et al., Am J Sports Med (2013) (Epub ahead of print).
