Patient\u2010reported outcomes, including Knee Injury and Osteoarthritis Outcome Score (KOOS) and visual analog scale (VAS) score, were collected at multiple time points (baseline, 1 week, 6 weeks, 3 months, 6 months) out to 12 months to assess improvements in pain and function. Radiographs at baseline and 12 months were taken to determine radiographic changes, while blood was collected at baseline, 6 weeks, and 6 months to determine changes in immunoglobulins and anti\u2010HLA levels. Statistical analyses were performed using last observation carried forward and mixed effects model for repeated measures.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Treatment with ASA resulted in significant improvements in KOOS and VAS scores that were maintained through 12 months (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .05). Treatment with ASA resulted in a 63.2% responder rate at 12 months using the Outcome Measures in Arthritis Clinical Trials\u2013Osteoarthritis Research Society International simplified definition.
