Reparación transtibial de la raíz posterior del menisco lateral en lesiones agudas: técnica quirúrgica y seguimiento clínico a corto plazo

Abstract

Backgroundinjuries of posterior lateral meniscus root (PLMR) affect the transfer of the axial load of the knee. Several surgical techniques have been described for it treatment, but still none has demonstrated superiority. Consequently, there are controversies about which technique is most indicated for these injuries. The aim is to describe the a surgical technique and the clinical follow up of patients operated with transtibial fixation of PLMR in a specialized clinic, during the 2016-2017. MethodsRetrospective case series and description of the surgical technique. We included patients with acute injuries in the PLMR, who were operated using a new variation to the transtibial technique. For the clinical follow-up, the IKDC and Lysholm scores were performed before and after surgery. ResultsSix patients with acute lesion in the PLMR were intervened, four were male. The time between trauma and surgery was on average 2.5 months. All the patients presented a concomitant lesion of the anterior cruciate ligament. When comparing the initial state of the patients and the postoperative period, statistically significant differences were found (p <0.05). Likewise, reinterventions were not performed during follow-up. DiscussionThe repair of PLMR with the new variation of the transtibial fixation provides an improvement in the function, the pain and the level of activity of the patients, which can help to delay the progression of osteoarthrosis in the knee. Likewise, this technique can be performed safely even in cases of concomitant ligament injuries.Level of clinical evidence: Level IV
