Poster 241: Outcomes of Trochleoplasty for Recurrent Patellar Dislocation in Adolescents with Open Physes
Objectives:
Patellofemoral dislocation, the most severe presentation on the spectrum of patellar instability, is most common in adolescent populations. Trochlear dysplasia is an integral component of the disorder, and procedures aimed at correcting instability by addressing this dysplasia are often necessary. A theoretical risk of injury to the distal femoral physis exists in these surgeries. At our institution, a thick-flap sulcus deepening technique is used to re-shape the trochlear groove. The risk of injury to the physis in this procedure is not clearly delineated in the current literature. We investigated the outcomes in adolescent patients undergoing this procedure, hypothesizing that patients with open distal femoral physes and less than 2 years of remaining growth can safely and successfully undergo thick-flap sulcus deepening trochleoplasty.
Methods:
Seventeen adolescents (21 knees) with open physes underwent thick-flap trochleoplasty at our institution. Preoperative radiographs were used to evaluate leg axis and patella alta. Preoperative MRI was used to determine trochlear dysplasia (sulcus depth, spur height, patellofemoral index) and tibial tuberosity to trochlear groove distance (TTTG) distance. Preoperative and postoperative AP and lateral radiographs were used to evaluate and compare the lateral distal femoral angle (LDFA) and Blumensaat’s angle (BA). Preoperative and postoperative IKDC and Kujala outcome scores were measured to evaluate clinical improvement.
Results:
Median age at time of operation was 14.9 years for girls and 15.5 for boys. Mean follow up was 5.4 years from surgery. At two-year follow up, growth plates were closed in all but one knee. No clinical differences to the leg length or alignment were appreciated. There was no statistically significant change in lateral distal femoral angle (mean change 0.74 degrees, p = 0.1074). There was a statistically significant change in Blumensaat’s angle (mean change 0.89 degrees, p = 0.0477). Mean Kujala score improved significantly from 60.19 preoperatively to 90.36 postoperatively, p= 0.0008. Mean IKDC score improved significantly from 59.37 preoperatively to 87.21 postoperatively, p = 0.00064. There was recurrent instability in one knee, requiring revision surgery with distal femur and Fulkerson osteotomies.
Conclusions:
Adolescent patients nearing skeletal maturity can safely and successfully undergo thick- flap sulcus deepening trochleoplasty for patellar instability resulting from trochlear dysplasia. At follow- up, there was no clinical evidence of growth disturbances, and postoperative imaging demonstrated less than 1 degree difference in LDFA and BA at skeletal maturity, which are unlikely to be of clinical significance. These findings should be interpreted very carefully, as specific patient selection, trochleoplasty expertise, and extreme caution are still necessary to prevent iatrogenic injury to the distal femoral physis.

O13.3 High prevalence of cervico-vaginal infections among female adolescents in four urban regions of panama
BackgroundFew data exist on cervico-vaginal STI among adolescents in Panama. The aim of this study was to determine the prevalence and correlates of cervico-vaginal STIs among female school-going adolescents in urban regions of Panama.MethodsA multicentric cross sectional study using multistage cluster sampling, with random selection of schools and clusters was conducted among participants aged 14–19 years enrolled in public high schools in the urban regions of Panama, San Miguelito, Colón, and Panamá Oeste, accounting for 53% of the country´s population. One region was studied each year between 2015 and 2018. Participants self-administered a questionnaire and gave urine samples. Those who self-reported sexual activity were tested for Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Mycoplasma genitalium (MG), andTrichomonas vaginalis (TV)by PCR. Correlates of infection were analyzed using univariate (OR) and age adjusted analyses (AOR).ResultsA total of 1404 female adolescents (median age 17) participated. More than half (57.3%) reported a history of sexual activity; of those, 27.4% had ≥1 positive STI test (22.8% positive for CT, 2.2%NG, 3.9%MG, 2.3%TV). Almost all participants with NG also had CT (15/18, 88.2%); nearly half with MG also had CT (13/31, 41.9%). Correlates did not change when removing non-CT infections; correlates of one or more STI included: three or more sex partners in the past year (AOR=4.12, 95%CI: 1.13–15.1), sex with a casual partner at least once (AOR=3.5, 95%CI: 1.6–7.7), reported sex in the past month (OR=1.8, 95%CI: 1.3–2.7), and reported anal sex (OR=1.6, 95%CI: 1.1–2.4). Protective correlates included study sites Colón and Panamá Oeste (AOR=0.3, 95%CI: 0.1–0.7; AOR=0.2, 95%CI 0.1–0.4).ConclusionThis study found very high prevalence of cervico-vaginal STIs, especially CT among high school-going female adolescents in urban Panama regions. Results indicate the need for interventions that target female adolescents, such as screening and treatment in urban Panama.DisclosureNo significant relationships.

Adaptation and validity evidence of the Child-Adolescent Perfectionism Scale to Brazilian Portuguese
This study presents the Brazilian version of the Child-Adolescent Perfectionism Scale (CAPS), one of the most widely used instrument for the assessment perfectionism in young people. The study was conducted on a sample of 599 adolescents (Mean age = 15.46 SD = 1.15), 66% girls. We investigated CAPS internal structure, measurement properties according to age and sex, and its relationship with other questionnaires. We found good fit for a two-factor structure for the CAPS controlling for acquiescent responding style χ²(207) = 774.25 p < .001 CFI = .930 TLI = .922 RMSEA = .068 (90% CI = .063 - .073) SRMR = .068. We found evidence of invariance across participants’ sex and lack of bias (using a MIMIC approach) due to participant age. There was an association of the CAPS scores with personality traits and a measure of mental health. The CAPS can be used as a questionnaire to assess perfectionism in Brazilian adolescents.
