Reinforced, cemented modular stems are available as an option
Wide choice of modular stems available. Following the failure of a knee prosthesis and/or osteosynthesis with loss of function of the extensors, arthrodesis may be the only surgical option for stabilizing the joint. Implantation of a Endo-Model Knee Fusion Nail SK enables fast and loadable mobilization of the patient. Loss of leg length can also be limited in this way.
The Endo-Model Knee Fusion Nail SK is placed like a coupled knee prosthesis with stem. In the event of infection, targeted topical antibiotic treatment is achieved via the cementing. The Knee Fusion Nail comprises of a femoral and a tibial component. The two components are stably connected by a special coupling. In the modular version, it can be combined with both cemented and cementless modular stems.
The stems of the cemented version are tapered, but have three flat planes for anti-rotation securing in the cement bed. The implant components are given an anatomical curvature of 5° flexion immediately after coupling. Centralizers ensure correct intramedullary positioning at each end of the nail.

High degree of flexibility provided by modular stem components and stem lengths of 60 mm to 280 mm from the Endo-Model Rotational and Hinge Knee System
Longitudinal ribs for rotational stability
Three flat sections for rotational stability in the bone cement
Secure connection: oblique contact surfaces provide tapered locking of the coupling
Modular A high degree of intraoperative flexibility provided by modular combination options for individual, finely graduated treatment of major bone defects Compatible. For specific solutions based on experience and compatibility with successful LINK revision implants Proven In terms of material, stability, and many years of clinical use
The modular MEGASYSTEM-C was developed in collaboration with Prof. Dr. Capanna and other experienced orthopedic surgeons. The many and varied treatment options permit both partial bone replacement in the proximal and distal femur region with very small gradations, and also total femur replacement and long tibia replacement.
For intraoperative flexibility, the MEGASYSTEM-C is based on the Endo-Model SL Knee Implant, the secure modular connections, and the flexible choice of anteversion, leg and neck length by employing the connection principle of the MP Reconstruction Prosthesis.
The best possible prospects for the surgical outcome are created by incorporating biomechanical loading and anchoring principles plus many years of experience gained from the use of proven implant components.
The advantages for you
You extend the Endo-Model SL (and also Endo-Model W) and use MP Neck Segments. Intraoperative choice between partial and total femur replacement. According to individual patient requirements, the surgeon is free to choose, during the course of the surgery, either to implant
a push-through stem to preserve the diaphyseal femoral bone or
to move up to total femur replacement by using stem segments.
This is made possible by the compatibility with two constrained knee systems (Endo-Model SL and Endo-Model W). These prostheses can be combined with the proximal hip components of the MP Reconstruction Prosthesis.
Proximal femur replacement and tibia replacement
Solid neck segments are available, including trial prostheses, with holes for fixation of the surrounding muscles and ligaments
Proximal tibia replacement with integral patella clamp and drill holes for attaching the soft tissues
10 mm build-up steps for leg length reconstruction
Use of the assembly instruments
Intelligently designed tapered connections
Securing the taper connection with the fixation screw
In cases of extensive bone defects which cannot be treated with normal acetabular cup systems, the Partial Pelvis Replacement Endo-Model forms the basis for the treatment with a cemented acetabular cup. The Partial Pelvic Replacement Endo-Model can be combined with various LINK hip prostheses.
