Division: Knee Reconstruction
Category: Limb Preserving
Significant bone loss requiring extensive reconstruction around the hip and knee is often required following the treatment of malignant bone tumors, aggressive benign bone tumors, 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.
DePuy Synthes Joint Reconstruction’s LPS System is intended for use in replacement of the mid-shaft portion of the femur, proximal, distal and/or total femur, and proximal tibia, especially in cases that require extensive resection and replacement. Specific diagnostic indications for use include:
The LPS System is also intended for use in bone loss post-infection, where the surgeon has elected to excise the bone and replacement is required.
The S-ROM® System tibial tray and the non-porous coated straight and bowed stems are intended for cemented use only.
The porous-coated metaphyseal sleeves are intended for either cemented or cementless applications.
|Ability to address bone loss secondary to tumor, end-stage revision, infection or severe trauma||Provides the surgeon intra-operative flexibility to meet patient needs|
Comprehensive, modular system can be utilized for:
|Meets the rigorous demands of limb preservation surgery|
|Ability for resection adjustments in 5 mm increments||
Allows for bone conservation
Ability to fine tune leg length adjustment
|Stem extension components are available in cemented and porous options||
Cemented or cementless based on surgeon preference
Biologic fixation option through exclusive POROCOAT® Porous Coating
|The LPS Universal tibial hinge insert bearing is compatible with the MBT Revision tray.||
Provides intra-operative flexibility for use in a hinged femoral component, distal femoral replacement, or total femoral replacement
Allows for the use of tibial metaphyseal sleeves to fill metaphyseal defects in the proximal tibia.
|Universal femoralmetaphyseal sleeves can be utilized with the LPS System distal femoral component.||Femoral metaphyseal sleeves can be used to fill metaphyseal defects in the distal femur and provide a stable foundation for the knee components.|
