ABSTRACT
El objetivo de este estudio fue evaluar si las medidas antropométricas y demográficas de pacientes con esqueleto inmaduro pueden ser utilizadas para predecir el diámetro del autoinjerto semitendinoso-gracilis (ST-G) en la cirugía de reconstrucción del ligamento cruzado anterior (LCA). Métodos: Serie retrospectiva de 169 pacientes con esqueleto inmaduro (112 hombres, 57 mujeres, edad media 15,8 años) que se sometieron a cirugía de reconstrucción del LCA con autoinjerto ST-G. Se registraron las medidas antropométricas (peso, talla e índice de masa corporal [IMC]), datos demográficos (edad y sexo) y diámetro del autoinjerto ST-G utilizados. Se utilizaron coeficientes de correlación, regresión lineal y t de Student para determinar la relación entre variables antropométricas-demográficas y el diámetro del injerto. Los valores de p < 0,05 fueron considerados estadísticamente significativos. Resultados: El análisis estadístico mostró una correlación positiva significativa tanto para la talla y el peso con el diámetro del injerto (r = 0,483, p < 0,0001; r = 0,248, p = 0,001, respectivamente). Sin embargo, la edad y el IMC no se correlacionaron con el diámetro del injerto (r = 0,098 y p = 0,203, r = 0,009 y p = 0,905, respectivamente). La media del diámetro del injerto en los hombres fue de 8,2mm (rango 6-10) y 7,5mm en las mujeres (rango 6-9), diferencia que fue estadísticamente significativa (p < 0,001). Conclusiones: La predicción del diámetro del injerto ST-G según la talla del paciente es un método fácil y fiable en pacientes con esqueleto inmaduro. Estos datos pueden proporcionar información preoperatoria relevante sobre la necesidad de una técnica para aumentar el injerto ante un eventual diámetro insuficiente de este...
The aim of this study was to evaluate whether the anthropometric and demographic measures of patients under 18 years old can be used to predict the diameter of semitendinosus-gracilis (ST-G) autografts in anterior cruciate ligament (ACL) reconstruction surgery. Methods: A study was conducted on retrospective series of 169 patients under 18 years (112 men, 57 women, average age 15.8 years) who underwent to ACL reconstruction surgery with ST-G autograft. The anthropometric measurements were recorded (weight, height and body mass index), demographics (age and gender) and the diameter of the ST-G used. Correlation coefficients, linear regression and unpaired t-test were used to determine the relationship between anthropometric/demographic variables and the diameter of the graft. P values <.05 were considered statistically significant. Results:Correlation analysis showed a significant positive relationship between height and graft diameter (r=0.483, P<.0001), as well as between weight and graft diameter (r=0.248, P=.001). However, age and body mass index (BMI) did not correlate with graft thickness (r=0.098 and P=.203, r=0.009 and P=.905, respectively). The mean graft diameter in men was 8.2 (range 6-10) and 7.5 in women (range 6-9), a difference that was statistically significant (P<.001). Conclusions:Prediction of the ST-G graft diameter according the height of the patient is an easy and reliable method in children and adolescents. These data can provide relevant preoperative information on the need for an alternative graft source for an eventual insufficient diameter of the latter...

PURPOSE: In anterior cruciate ligament (ACL) injury, conventional adult reconstruction techniques have to face the potential risk of growth disturbance or angular deformities in skeletally immature patients. The aim of this study was to evaluate the clinical outcomes of ACL reconstruction by conventional transphyseal tunnel technique. MATERIALS AND METHODS: On a retrospective basis, we reviewed 25 skeletally immature patients; all the patients showed skeletal maturity at last follow-up, and the mean age was 16.4 years. The average injury to surgery interval was 12.6 months. Clinical outcomes were assessed at a mean of 74.4 months postoperatively using the Lysholm Knee Scoring Scale, the Tegner activity level, the International Knee Documentation Committee (IKDC), and plain radiographs. RESULTS: All the patients had undergone transphyseal reconstruction of ACL. The mean Lysholm score was 48.36 points preoperatively and 93.32 points postoperatively; the mean Tegner activity level was changed from 3.0 points to 5.6 points. The mean IKDC level was categorized as C preoperatively and changed to A postoperatively. CONCLUSIONS: Our midterm outcome at an average 6 years after surgery was satisfactory without significant leg length discrepancies or abnormal alignment of the knee joint. Transphyseal reconstruction of ACL is a good treatment modality in the skeletally immature patient.
