Diagnosis of patellofemoral dislocation or subluxation was based on the patient's report plus reproduction of subjective complaints of instability on physical examination. All patients were treated by the same surgeon. Assessment was performed by a different surgeon based on Crosby\u2010Insall and Aglietti criteria.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>According to Crosby\u2010Insall criteria, 11 knees were rated as excellent, 4 good, and 1 poor. According to Aglietti criteria, 11 knees were rated as excellent, 3 good, 1 fair, and 1 poor. According to both protocols, 15 knees showed negative apprehension test, absence of patellofemoral pain, and normal patellar tracking. In one knee, the apprehension test was positive, patellofemoral pain was present, and patellar tracking was abnormal. Patellofemoral crepitus was detected in 10 knees (attenuated in 6). Thirteen patients (14 knees) were satisfied with the results. One patient considered the result acceptable, but below expectations. The final patient underwent an additional procedure. No cases of infection and no vascular problems were seen.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n
