In adults, diagnostic arthroscopy (DA) has identified chondral injuries in up to one-third of cases where magnetic resonance imaging (MRI) was negative. However, the value of DA in detecting cartilage injuries in pediatric patients undergoing medial patellofemoral ligament reconstruction (MPFLR) has not been well studied.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Purposes:<\/jats:title>\n                    <jats:p>To evaluate the utility of DA in diagnosing cartilaginous injuries in pediatric patients undergoing MPFLR with negative preoperative MRI findings and to compare postoperative outcomes between patients with and without chondral injury findings on DA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Study Design:<\/jats:title>\n                    <jats:p>Cohort study (diagnosis); Level of evidence, 3.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>A retrospective review was conducted on patients aged 0 to 18 years who underwent combined MPFLR and DA procedures from 2015 to 2023 at a single institution. The exclusion criteria were as follows: revision MPFLR; tibial tubercle osteotomy; multiligament reconstructions; and previous meniscal injury. MRI and DA reports were reviewed for chondral findings. Patients were classified into 3 groups: +MRI\/+DA, \u2013MRI\/+DA, and \u2013MRI\/\u2013DA. Subgroup analysis was performed within the \u2013MRI\/+DA group to compare outcomes in the immediate postoperative recovery period between those who underwent a chondroplasty versus those who did not.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Of the 155 patients included, follow-up averaged 7.8 months (median, 5 months [range, 0-41 months]).
