Introducción En los últimos años ha cobrado importancia la reconstrucción del LPFM. La técnica más utilizada es con autoinjerto de tendones isquiotibiales. En algunas series los reportes de complicaciones son mayores al 26%. Este trabajo pretende demostrar la utilidad del autoinjerto del cuádriceps para la reconstrucción del LPFM, sin túneles rotulianos y sin el uso de fluoroscopia intraoperatoria. Materiales y métodos Se incluyeron pacientes con historia clínica de al menos dos episodios de luxación. Se tomaron en todas los pacientes serie radiográfica, TAC axial rótulas, TAC 3D y RNM. Se obtuvo registro de manera retrospectiva de puntuaciones en las escalas de Lysholm, Tegner y Kujala en el posoperatorio con controles a los 6,12 y 18 meses. Resultados Cumplieron con los criterios de selección 24 pacientes, 16 mujeres y 8 hombres, edad promedio de 23 años.En nuestro estudio se observó la mejoría de puntuaciones en las escalas de Lysholm, Tegner y Kujala en el posoperatorio con controles a los 6,12 y 18 meses. Sin presentarse nuevos episodios de luxación rotuliana u otras complicaciones relevantes. Hubo un retorno en todos los casos a la actividad deportiva. Discusión Este estudio reafirma que el tendón cuadricipital es un injerto que reproduciendo mejor la anatomía del LPFM, presenta cifras comparables o mejores funcionalmente con los otros injertos utilizados en la actualidad. Con el protocolo preoperatorio de TAC3D se ha conseguido identificar en forma individual y con la especificidad anatómica de cada paciente, al tubérculo aductor y epicóndilo medial, dando mayor certeza en la ubicación anatómica de la inserción femoral LPFM. Con las ventajas adicionales de disminuir el tiempo quirúrgico, y evitar radiación innecesaria en el equipo quirúrgico.

Background The reconstruction of the medial patellar-femoral ligament (MPFL) has become increasingly important in recent years. The most used technique is a hamstring tendons autograft. Complications of greater than 26% have been reported in some series. The aim of this study is to demonstrate the use of quadriceps autograft for the reconstruction of the MPFL, without patellar tunnels and without the use of intraoperative fluoroscopy. Methods A Case Series study was performed. Patients with a clinical history of at least two episodes of dislocation were included. A series of x-rays, axial Computed Tomography (CT), patellae, 3D CT, and MR image were taken in all patients. Scores on the Lysholm, Tegner, and Kujala scales were used in the postoperative period, with controls at 6, 12 and 18 months being recorded Results A total of 24 patients, 16 women and 8 men, with a mean age of 23 years, met the selection criteria. An improvement was observed in the scores on the Lysholm, Tegner, and Kujala scales in the postoperative period, with controls at 6, 12, and 18 months. No new episodes of patellar dislocation or other relevant complications were observed. There was a return to sports activity in all cases. Discussion This study reaffirms that the quadriceps tendon is a graft that reproduces the anatomy of the MPFL better, shows figures comparable or functionally better than with the other grafts used at present. Using the preoperative protocol of 3-D CT scans, the adductor and medial epicondyle tubules have been identified individually and with the anatomical specificity of each patient, giving greater certainty in the anatomical location of the MPFL femoral insert. This also has the additional advantages of decreasing surgical time, and avoiding unnecessary radiation in the surgical team.

Comparative Results of Arthroscopic Anterior Cruciate Ligament Reconstruction with Autologous Quadriceps Tendon-bone Versus Bone-patellar Tendon-bone

PURPOSES: We analyzed the comparative results of arthroscopic anterior cruciate ligament reconstruction using the autologous quadriceps tendon-bone versus the bone-patellar tendon-bone. MATERIALS AND METHODS: Thirty-three patients with ACL reconstruction using the autologous quadriceps tendon-patellar bone were evaluated (group 1). Control group were 33 patients underwent ACL reconstruction with autologous bone-patellar tendon-bone in similar period (group 2). The mean age was 29.7 years in group 1 and 23.5 years in group 2. The mean follow-up period was 20.8 months in group 1, and 21.8 months in group 2. We selected the patient with the similar age, conditions and operation methods. But group 1 with bone-to-tendon graft healing at one side was delayed rehabilitation program than group 2 (bone-to-bone healing). The final evaluation were range of motion, anterior knee pain, Lachman test, KT-2000 arthrometer, Lysholm score, IKDC evaluation, one-leg hop muscle function test. Student ttest was used for statistical analysis (p 0.05). According to the International Knee Documentation Committee (IKDC) rating system, normal were 30.3%, nearly normal 57.6%, abnormal 12.1% in group 1, and in group 2 normal was 24.3%, nearly normal was 63.6%, abnormal 12.1%. There were no statistical differences in normal and nearly normal rate between two groups (p> 0.05). Recovery of quadriceps strength by one-leg hop test was 78% of the normal knee in group 1, and 80% in group 2 (p> 0.05). CONCLUSION: There were no significant differences of clinical results in ACL reconstruction using between quadriceps tendon-bone and bone-patellar tendon-bone, but anterior knee pain. We consider that autologous quadriceps tendon-bone is a good alternative substitute in ACL reconstruction together with the bone-patellar tendon-bone.
