Lesiones del ligamento cruzado anterior en esquiadores: conceptos actuales / Anterior cruciate ligament injuries in skiers: current concepts

El esquí es un deporte individual con una tasa de lesiones de 1,84 por 1.000 días esquiador en la población general. Las roturas del ligamento cruzado anterior (LCA) son algunas de las más comunes, llegando a una tasa de 5 por cada 100 esquiadores por temporada a nivel competitivo, debido a la gran exigencia a la que se encuentran sometidas las rodillas. Lo anterior presenta un desafío para el traumatólogo a la hora de plantear un manejo. Se realizó una revisión de la literatura respecto de los mecanismos de lesión, tratamiento, prevención, rehabilitación y uso de órtesis en el retorno deportivo. Se describen los mecanismos clásicos de lesión en esquiadores amateurs y competitivos. La mayoría de las lesiones de LCA son de resolución quirúrgica, en que la recomendación de reconstrucción debe ser con injerto autólogo de hueso-tendón patelar-hueso, salvo en los pacientes mayores o en pacientes con fisis abierta, en los que se recomienda el uso de injerto autólogo de semitendinoso-gracilis. La prevención y rehabilitación se basan en mejorar la fuerza y el control neuromuscular de los estabilizadores dinámicos de la rodilla implementándose programas específicos, evaluación del gesto deportivo, y pruebas de control neuromuscular. Se recomienda el uso de órtesis funcionales adecuadas en los pacientes sometidos a reconstrucción del LCA. Las lesiones de LCA en esquiadores de nivel competitivo son habituales, de manejo específico y multidisciplinario. La elección del injerto y del tipo de rehabilitación son fundamentales en el retorno deportivo del esquiador. NIVEL DE EVIDENCIA: V.

Skiing is an individual sport with an injury rate of 1.84 per 1,000 skier days among the general population. Anterior cruciate ligament (ACL) tears are among the most common injuries in skiers, with a rate of 5 per 100 skiers per season at a competitive level, because of the great demand placed on the knees. Their treatment is a challenge for orthopedic surgeons. A review of the literature was carried out regarding injury mechanisms, treatment, prevention, rehabilitation, and the use of bracing in the return to sports. The classic injury mechanisms in amateur and competitive skiers are described. Most ACL injuries require surgical resolution, with reconstruction using autologous bone-patellar tendon-bone graft, except in older patients or those with open physis, who must receive an autologous semitendinosusgracilis graft. Prevention and rehabilitation are based on improving strength and neuromuscular control of the dynamic knee stabilizers, implementing specific programs, evaluating the sport movements, and performing neuromuscular control tests. Suitable functional bracings are recommended in patients undergoing ACL reconstruction. ACL injuries in competitive-level skiers are common, and their management is specific and multidisciplinary. The choice of graft and rehabilitation type is critical to resume skiing. LEVEL OF EVIDENCE: V.

Short term clinical results of single bundle ACL reconstruction, with a quadruple autologous hamstring graft, modified transtibial versus anteriomedial portal approach for femoral tunnel

Anteriior cruciate ligament injuries are known to be the most common spots injuries, and ACL reconstruction is widely used because of the low success rate of convservative treatment. This study was aimed to compare the short-terma functional results of modifying transtibial and transportal technique for femoral tunnel drilling. This Retrospective comparative case control study included 76 patients with an isolated ACL tear, operated with ST tendon autograft ACL reconstruction by the same surgical tea. 36 patients operated with a modified transtibial approach and 40 patients with an antreomedial approach for femoral drilling. The results of the current study revealed that the mean age in the series was 26 years; the majority of patients were male, only 6 patient's asses again after two years of surgery, by instability tests and lysholm scores reveal no significant differences between two group regarding anterioposterior and rotatory instability, also comparable lysholm score results. The Study concluded that modified transtibial femoral drilling of the femoral tunnel in ACL reconstruction surgery is still useful and give comparable results as tranportal drilling (AU)
