A simple technique to perform total knee replacement without violating the femoral canal: early clinical results on a cohort of 303 patients

Experimental and clinical analysis of the use of asymmetric vs symmetric polyethylene inserts in a mobile bearing total knee arthroplasty

“…The PCL was preserved in all patients, and ligaments release was avoided whenever possible by the use of a Minimally Invasive alignment device (EMAS, Extra-Medullary Alignment system) offered by the manufacturer. [15][16][17] In detail, the EMAS device allows for femoral component positioning and joint balancing without requiring the use of intramedullary rods, avoiding violation of the intramedullary canal, which can potentially enable the incidence of fat embolism and perioperative blood loss or femoral fractures risk in the case of osteoporotic bone. 2,15,18,19 Particular care was taken to minimize the tibial bone cut, in order to preserve bone integrity.…”

The use of mobile bearing TKA in valgus deformities – A clinical study

“…The EMAS device used in the surgeries involved is a dynamic spacer that can help correcting the deformities and achieving a rectangular space in flexion and extension, 4 allowing to address the above-described issues without performing ligament release: therefore, the use of an unconstrained implant can be taken into consideration as the stability is not flawed by any soft tissue release and thus acceptable outcomes can be achieved with mobile bearing models also in case of severe valgus cases.…”

“…The surgical procedure performed on all patients was previously described by Castellarin3 and Castellarin and Cimino. 4 Relying on the use of a dedicated surgical tool, called Extramedullary Alignment System (EMAS, Adler Ortho SpA, Cormano, Italy), an innovative surgical technique was developed and initially employed for TKA with inaccessible femoral canal. 3 This technique has shown to be reliable also for standard cases, allowing to perform TKAs without violating the femoral canal.…”

Is Total Knee Arthroplasty Surgical Performance Enhanced Using Augmented Reality? A Single-Center Study on 76 Consecutive Patients

“…The surgical technique involved in the present study has been described in previous publications [15,16]. This technique involves performing the tibial osteotomy first, attempting to respect the patient's joint line as much as possible; for this reason, a slight varus cut on the coronal plane was aimed for in most cases.…”
