Follow\u2010up examinations after a minimum of 8 years included clinical examination, measurement of anterior tibial translation (rolimeter), International Knee Documentation Committee Subjective Knee Form (IKDC), 12\u2010Item Short Form Health Survey (SF\u201012), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Marx and Tegner scores. Osteoarthritis severity was described on radiographs using the Kellgren\u2013Lawrence scale. Synovial fluid was aspirated from patients with persistent infection signs and evaluated using multiplex polymerase chain reaction (PCR). Based on ACLR graft, sex and preoperative Tegner score (\u00b11), a 1:1 propensity score matched control group including patients with ACLR without knee SA signs was assembled.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Matching resulted in 17 patients per group. While the patient\u2010reported outcome measures (PROMs) (IKDC, Tegner, Marx and SF\u201012) showed no significant differences between the groups (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&gt;\u20090.05), the WOMAC score was significantly worse in the infection group (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.016).

Multiplex PCR detected no persistent infection. Two patients (10%) in the infection group required graft removal. No correlation was found between the number of lavages and long\u2010term outcomes.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
