The LCS COMPLETE Revision Knee System is based upon the design principles of the clinically proven LCS Knee1. This system offers surgeons solutions to help address the wide variety of soft tissue and bone defects often encountered during revision TKA.

S-ROM NOILES Knee System (NRH) is a clinically-proven1 hinge design for patients with severe soft tissue instability and/or bone deficiency. The system allows for optimal fit and fill for a wide range of bone deficiencies with the utilisation of modular wedges, stem extensions, and metaphyseal sleeves.

Whilst maintaining all of the LCS design features in the walking phase of gait the LCS-RPS utilises a spine and cam mechanism in flexion. This reduces the potential for A-P translation by keeping the femoral component centralised as the knee goes into flexion. This centralisation reduces the risk of posterior impingement and therefore allows the knee the freedom to achieve deeper flexion angles.
The LCS is well known as a low wear solution due to its design which allows total freedom of rotation resulting in unidirectional motion patterns. To minimise any potential for 3rd body wear the cam and spine in the LCS-RPS have been carefully designed to evenly distribute stresses and to permit the freedom of movement required to allow normal rotation and lift off. Married with the decoupling forces provided by the clinically proven1 Mobile Bearing Tibial tray, the LCS-RPS remains a low wear choice.
Significant bone loss requiring extensive reconstruction around the hip and knee is often required following the treatment of malignant bone tumours, aggressive benign bone tumours, infection, multiple revised and failed joint replacements and massive trauma, particularly in the elderly osteoporotic patient. Limb-preserving techniques, using modular segmental endoprostheses, provide a reliable, functional reconstruction for these patients. Due to unpredictable and difficult conditions encountered with the remaining bone, muscle and soft tissues, the prosthetic construct must perform under severe conditions. DePuy Synthes Joint Reconstruction Revision Solutions offers both surgeons and patients a comprehensive portfolio of products for managing the many challenges of total joint arthroplasty. The DePuy Synthes Joint Reconstruction LPS (Limb Preservation System) is designed with these considerations in mind to allow for versatility and predictability in such difficult reconstructions.
The SIGMA® TC3 design is a semi-constrained device available within the SIGMA Knee System. It is indicated for use in cases where the lateral collateral ligament is absent or deficient. The SIGMA TC3 Femoral and Tibial Insert components incorporate the clinically successful design characteristics of the original TC3 (first implanted in 1993). If the medial collateral ligament is deficient, in some cases the use of S-ROM® Noiles may be required.
SIGMA TC3 Femoral components share common design with the SIGMA Posterior Stabilized primary femur, with the exception of the femoral box which maintains the same width but higher SI dimension to allow for more constraint. This system's approach to revision knee surgery provides the surgeon with maximum intraoperative flexibility as the surgeon can decide the extent of constraint, mixing and matching primary and revision components using the same MBT Revision Tibial Tray.
The SIGMA TC3 is available in both Fixed Bearing and Rotating Platform options. The SIGMA TC3 RP is designed to reduce the torsional forces at implant-bone interface during gait. The Metaphyseal Sleeves are used with both the femoral and tibial components to transfer the aid for implant fixation and stimulate bone growth.
The SIGMA TC3 Knee is intended for cemented use only, while Metaphyseal Sleeves are for cementless use.
The SIGMA® High Performance Partial Kneesystem comprises ofunicondylar and patellofemoral implants and a full range of instruments to perform both of these procedures.
The SIGMA® Knee System offers a comprehensive, integrated knee system. Based on the P.F.C® Total Knee System introduced in 1984, the SIGMA Knee continues a history of innovation based on clinical heritage.
The SIGMA Knee embraces a wide variety of surgeon philosophies and surgical techniques, while providing function, clinical results, and a variety of options for today’s patients. Available in posterior cruciate retaining or posterior stabilized femoral component designs, and fixed and mobile-bearing tibial component designs, this knee system is designed to provide surgical solutions for a variety of clinical indications.
The LCS Knee System is based upon the original LCS Mobile-Bearing Knee System, featuring the same low contact stress articular geometry. This rotating platform system offers surgeons cruciate sacrificing and posterior stabilised femoral and tibial insert components (GVF™ and AOX™) and fixed all-poly and mobile bearing metal-backed patella components. The system also includes versions with cemented and cementless fixation, including POROCOAT® and DUOFIX™.
LCS can be used with High Performance Instruments specifically designed for use with the LCS knee system.
