This report is being filed after the review of the following journal article: zitsch, b.P.Et al.(2020), patient-reported outcomes for large bipolar osteochondral allograft transplantation in combination with realignment osteotomies for the knee, the journal of knee surgery, vol xx, pages 1-7, (usa).The purpose of this study was to evaluate clinical and patient reported outcomes for a cohort of patients who underwent surgical restoration of the knee by osteochondral allograft (oca) transplantation, with either staged or concurrent distal femoral osteotomy (dfo) or high tibial osteotomy (hto).The overall goal is to demonstrate that combined oca transplantation with osteotomy can yield clinically meaningful improvements in patient reported outcomes.May 2016 to march 2018, 23 patients (15 males and 8 females) who underwent primary oca transplantation using the missouri osteochondral preservation system (mops)¿preserved oca and meniscal allograft along with concurrent or staged dfo or hto surgeries were analyzed.13 patients received hto, 5 of which had a concurrent procedure.10 patients received dfo, five of which were concurrent.Implants used for osteotomies were locking plates (tomofix; depuy synthes, paoli, pa) with a combination of locking and cortical screws.The following complications were reported as follows: 4 patients underwent revisions.The four patients undergoing revision met functional criteria for success at final follow-up, resulting in a 2-year survival rate of 87.4%.3 patients failed and were converted to tka during the study period.1 patients experienced a major complication (septic knee or osteomyelitis) requiring reoperation.This report is for an unknown synthes locking plates (tomofix; depuy synthes, paoli, pa) with a combination of locking and cortical screws.This is report 1 of 1 for (b)(4).
