RESUMO
OBJECTIVES: Injury to the lateral ligament complex of the ankle is one of the most common sports-related injury. Usually lateral ankle evolves with excellent clinical recovery with non surgical treatment, however, near about 30% develop a lateral chronic instability sequela. Several open and arthroscopic surgical techniques have been described to treat this medical condition. MATERIAL AND METHODS: Of the 22 patients who were treated; 18 males and 4 females, and aged from 17-42 years (mean 28 years). All patients presented a history of more than three ankle sprains in the last two years and presented positive anterior drawer and talar tilt test of the ankle in the physical examination. We perform an anterior arthroscopy of the ankle in order to treat asociated disease and then we performed "All inside¨ lateral ligament repair through two portals (anteromedial and anterolateral) using an anchor knotless suture. RESULTS: Clinical outcome evaluations were performed at a mean follow up of 25 months. (R: 17-31). Overall results has been shown by means of the American Orthopaedic Foot and Ankle Society (AOFAS). Mean AOFAS scores improved from 63 points (range 52-77) preoperatively to 90 points (range 73-100) at final follow up. No recurrences of ankle instability were found in the cases presented. CONCLUSION: Several surgical procedures have been described during the last years in order to treat chronic ankle instability. ¨All inside¨ lateral ligament reconstruction presents lower local morbidity than open procedures with few complications. Moreover, it is a reproductible technique, with high clinical success rate, few complications and relatively quick return to sports activities. A high knowledge of the anatomic landmarks should be essential to avoid unwated injuries.
RESUMO
Objetivo: El presente estudio investigó la influencia entre 2 protocolos de rehabilitación (agresivo y no agresivo) en los resultados después de la reconstrucción del LCA utilizando autoinjertos de tendón patelar en futbolistas profesionales. Métodos: Se efectuó un estudio prospectivo ramdomizado incluyendo 84 pacientes divididos en dos grupos iguales tratados con 2 protocolos de rehabilitación diferentes: Agresivo y No Agresivo, en el postoperatorio. A los 3 años de seguimiento, se realizó una evaluación compuesta por el score IKDC, la medición KT 1000 y las imágenes de RM. Se utilizó la prueba t para muestras independientes y pareadas y la prueba de Chi-cuadrado de Pearson para el análisis estadístico (p / 0,05). Resultados: Sólo 69,04% (N = 58) de los pacientes fueron examinados a los 3 años después de la operación. Los resultados del score IKDC del grupo de rehabilitación NO agresiva (A 55%, B 35%, C 10%; del grupo de rehabilitación Agresiva A 52%, B 35%, C 13%) y la medición instrumental de la laxitud anteroposterior con artrómetro KT1000 (no agresivo 0.5 ± 2,1 mm, agresivo 0,9 ± 3,2 mm) no mostraron diferencias significativas. Se encontraron diferencias en las imágenes de RM entre ambos grupos obtenidas durante el postoperatorio inmediato y a 3 años de seguimiento. Con el protocolo Agresivo de rehabilitación se observó un aumento en la densidad y pérdida de nitidez del neoligamento, además de una diferencia significativa en el ensanchamiento de los túneles óseos y mayor sinovitis en relación al grupo que recibió un protocolo No Agresivo de rehabilitación. Conclusión: La rehabilitación postoperatoria con un protocolo agresivo de rehabilitación después de la reconstrucción del LCA presenta buenos resultados funcionales con imágenes alteradas de RM a 3 años después de la reconstrucción del LCA con tendón patelar en jugadores profesionales de fútbol.
Purpose: The current study investigated the influence of two-rehabilitation protocol (aggressive and no aggressive) in the results after ACL reconstruction using patellar tendon autografts in professional soccer players. Methods: A prospective randomized study was initiated including 84 patients divided into two equal groups treated with or without an aggressive rehabilitation protocol Post-operatively. A 3 years follow-up examination comprised the IKDC score, KT1000 measurement and MR images. The t test for independent and paired samples and the Pearsons Chi-square test was used for statistical analysis (p/0.05). Results: Only 69,04% (N=58) of the patients were examined 3 years post-operatively. IKDC, non-aggressive rehabilitation protocol group results (A 55 %, B 35 %, C 10 %; aggressive rehabilitation protocol group A 52 %, B 35 %, C 13%) and instrumental measurement of anteroposterior laxity with KT1000 (non aggressive 0.5 ± 2.1 mm, aggressive 0.9± 3.2 mm) showed no significant differences. There were MRI differences between the groups concerning heterogeneous images signal, continuity, and tunnel widening and synovitis findings in the aggressive rehabilitation protocol group. Conclusion: Post-operative rehabilitation with an aggressive protocol after ACL reconstruction present good functional results with poor images of MR 3 years post reconstruction of ACL with patellar tendon in professional soccer players.
