Endo-Model – M
with LINK PorEx coating for metal-sensitive patients
Design
The LINK Endo-Model has been in use for over 30 years as a rotational or hinge knee prosthesis for both primary and revision arthroplasties. The Endo-Model Rotational Knee Prosthesis gives you a multiplicity of options.
The method for implanting the Endo-Model is simple and uncomplicated.2, 6 The prosthesis has an intracondylar and an intramedullary fixation, which provide a high degree of stability and protection against bacteria.1, 7 For patients with a hypersensitivity to metal, LINK also offers a special surface coating (LINK PorEx).13
The Endo-Model is an implant with intrinsic stability.1, 5, 12 The various options (Endo-Model Standard, Endo-Model Modular, Endo-Model SL, Endo-Model W) offer a high degree of flexibility.
The Endo-Model has been used successfully for over 30 years now, and can boast an unparalleled clinical history with excellent clinical results.1, 2, 5, 8 Even after 15 years, the Endo-Model has a survival rate of 98.5%.9
The Endo-Model enables speedy and uncomplicated implantation, while the design of the implant ensures good postoperative function.10, 11 Its excellent kinematics mean that the Endo-Model gives a high level of stability, especially in extension.3, 11 The implant allows flexion of the joint up to 142° and hyperextension of 2°.
The Endo-Model is an implant with intrinsic stability.1, 5, 12 The various options (Endo-Model Standard, Endo-Model Modular, Endo-Model SL, Endo-Model W) offer a high degree of flexibility.
Features of Endo-Model Standard
Sizes:
4 different sizes for femoral and tibial components, for right and left in each case (XS, S, M, L).
Material:
CoCrMo, UHMWPE and LINK PorEx
(For metal-sensitive patients, LINK offers a surface modification.13)
Mechanism:
Available as a Rotating Hinge and Pure Hinge Version.
Type of fixation:
Cemented
Centralizers:
The shape of the centralizers enables a central position in the medullary canal. Furthermore, the centralizers prevent contact between the metal stem and the cortical bone, thus reducing stress peaks in the bone when bending forces are acting.3
Features of Endo-Model - M
The modular intracondylar total knee prosthesis, Endo-Model – M, is an addition to the Endo-Model Standard Knee Prosthesis.
Sizes:
4 different sizes for femoral and tibial components, for right and left in each case (XS, S, M, L).
Stem sizes:
- Modular stem, cemented
(EndoDur-S, LINK PorEx*): 50 mm-280 mm - Modular stem, uncemented, tapered
(Tilastan-S): 50 mm-280 mm - Modular stem, uncemented, cylindrical
(Tilastan-S): 60 mm (Ø 10-18 mm), 120 mm-280 mm (each size available in the following diameters: Ø 12-18 mm)
Meachanism:
Available as a Rotating Hinge and Pure Hinge Version.
Type of fixation:
Cemented and uncemented
Centralizers:
The shape of the centralizers enables a central position in the medullary canal. Furthermore, the centralizers prevent contact between the metal stem and the cortical bone, thus also preventing stress peaks in the bone when bending forces are acting.3
Material:
CoCrMo, UHMWPE and LINK PorEx
(For metal-sensitive patients, LINK offers a surface modification.13)
Features of Endo-Model – W*
The modular intracondylar total knee prosthesis, Endo-Model – W*, is an addition to the Endo-Model Knee Prosthesis.
Sizes:
3 different sizes for femoral and tibial components, for right and left in each case (S, M, L).
Stem sizes:
Modular stem, cemented (CoCrMo): 100 mm-160 mm (Ø 12-16 mm) Modular stem, uncemented (Tilastan): 100 mm-160 mm (Ø 12-24 mm)
Material:
CoCrMo, UHMWPE
Mechanism:
Available as a Rotating Hinge and Pure Hinge Version.
Type of fixation:
Cemented and uncemented
Centralizers:
The shape of the centralizers enables a central position in the medullary canal. Furthermore, the centralizers prevent contact between the metal stem and the cortical bone, thus also preventing stress peaks in the bone when bending forces are acting.3

Compatibility:
The Endo-Model-W is compatible with the MEGASYSTEM-C. All the stems from the MEGASYSTEM-C which have a male taper can be used. The high degree of modularity of this system allows both, partial bone replacement in the proximal and distal femur regions in small increments and also total femur replacement. You can find further information under MEGASYSTEM-C. *Internal designation
