The use of bioresorbable materials in the anterior cruciate ligament reconstruction is a promising direction. Thus today there is no single point of view on the long-term results of using absorbable interference screws. The article presents an analysis of the results of surgical treatment of 30 patients with use of bioresorbable materials, operated on for rupture of the anterior cruciate ligament (ACL) in the department of traumatology and orthopedics from 2010 to 2016 in the Federal Scientific Clinical Center FMBA of Russia. The aim of our study was to evaluate in vivo transformation of bioresorbable screws and bone assimilation into the tibial canal in long-term period after surgery, as well as the effect of the polymeric material and bone on these processes.

In the article authors describe the results of MRI studies of patients after reconstruction of the anterior cruciate ligament. The potential of biodegradable implants, timing of their location in the bone. The evaluation of bone response to biodegradable screws. The authors defined the terms of biodegradation clips from polylactic acid polymer and tricalcium phosphate.

В статье представлен анализ результатов хирургического лечения 71 пациента, прооперированных по поводу разрыва передней крестообразной связки (ПКС) в отделении травматологии и ортопедии Федерального научно-клинического центра ФМБА России с 2013 по 2016 г. Всем пациентам была выполнена первичная артроскопическая пластика ПКС аутотрансплантатом из сухожилий нежной и полусухожильной мышц. Мы оценивали состояние оперированного коленного сустава по данным МРТ через 3 -6 -12 -24 месяца после операции. На основании критериев МР-исследований были сделаны выводы, что неоднородное диффузное изменение МР-сигнала от трансплантата на Т2, PD FS может прослеживаться в первые 2 года после операции, отражая процесс лигаментизации. В первые 3 месяца мы также наблюдали увеличение диаметра трансплантата, которое в дальнейшем регрессировало. Процесс лигаментизации заканчивается в течение 2 лет после операции, в результате чего МР-сигнал от трансплантата должен быть схожим с нативной ПКС.Êëþ÷åâûå ñëîâà: передняя крестообразная связка, лигаментизация, трансплантат, МРТ. GRAFT LIGAMENTIZATION OF ANTERIOR CRUCIATE LIGAMENTAkhpashev A.A., Dzhambinova E.A., Zvezdkina E.A., Kanaev A.S., Tkalin A.N.The article presents an analysis of surgical treatment results of 71 patients, operated on for rupture of the anterior cruciate ligament (ACL) in the department of traumatology and orthopedics FSСС FMBA of Russia in 2013-2016. All patients underwent primary arthroscopic ACL reconstruction with autograft from tendons gracilis and semitendinosus. We assessed the condition of the operated knee joint on MRI after 3 -6 -12 -24 months after surgery. Based on the criteria of MR studies, we concluded that the non-uniform diffuse change of MR signal from the graft on T2, PD FS can be traced in the first 2 years after surgery, reflecting process of ligamentization. In the first three months we also observed an increase in the diameter of the graft, which further regressed. Process of ligamentization ends within two years after the operation, whereby the signal from the MR-graft should be similar to the native ACL.

The authors describe in detail the biochemical processes that occur over time and with the collapse of the polymer in the bone. Originally used scanning electron microscopy to assess the condition of clamps, which spent several years in the bone. The data obtained is objective evidence that the biological activity of the implant in the bone and again emphasize the importance of the choice of materials to be implanted in the human body.
