LOSPA II Knee System (EXULT Knee Replacement System) is intended for cemented application only. ## Device Story The LOSPA II Knee System is a total knee joint replacement prosthesis. This submission represents a line extension adding new sizes (#13) and a modified size (#12) to the existing femoral component portfolio (PS and CR types). The device is a mechanical implant used by orthopedic surgeons in a clinical/hospital setting to replace damaged knee joint surfaces. It functions by restoring joint configuration and stability in patients with degenerative or post-traumatic joint disease. The system is intended for cemented application. The device does not involve software or electronic processing; it is a passive orthopedic implant. ## Clinical Evidence Bench testing only. No clinical data was provided. The system's safety and effectiveness were supported by mechanical testing of worst-case predicate components, including tibial plate fatigue, constraint testing, contact analysis, insert disassembly, tibial insert post shear, wear testing, dislocation/jump distance, and range of motion, conducted in accordance with ASTM F1800, ASTM F1223, ASTM F2083, ASTM F1814, ISO 14243, and ISO 21536. ## Technological Characteristics Total knee joint replacement prosthesis. Femoral components manufactured from cobalt-chromium-molybdenum alloy (ASTM F75, UNS R30075). System includes PS (Posterior Stabilized) and CR (Cruciate Retaining) types. Supplied sterile. Mechanical, passive implant. No software or electronic components. ## Regulatory Identification A knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a knee joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a tibial component or components and a retropatellar resurfacing component made of ultra-high molecular weight polyethylene. This generic type of device is limited to those prostheses intended for use with bone cement (§ 888.3027). ## Predicate Devices - LOSPA II Knee System ([K192507](/device/K192507.md)) - LOSPA Knee System ([K130673](/device/K130673.md)) - LOSPA Knee System ([K110404](/device/K110404.md)) - LOSPA Knee System ([K121037](/device/K121037.md)) - LOSPA Knee System ([K160157](/device/K160157.md)) - LOSPA Knee System ([K190402](/device/K190402.md)) - Triathlon Total Knee System ([K173849](/device/K173849.md)) - Triathlon Total Knee System ([K172326](/device/K172326.md)) - Scorpio NRG Knee System ([K042343](/device/K042343.md)) - Scorpio NRG Knee System ([K071991](/device/K071991.md)) ## Related Devices - [K130673](/device/K130673.md) — LOSPA TOTAL KNEE REPLACEMENT SYSTEM · Corentec Co., Ltd. · Apr 15, 2013 - [K121307](/device/K121307.md) — OPTETRAK LOGIC CR TIBIAL INSERT, SIZE 0 OPTETRAK LOGIC CR TIBIAL INSERT, SIZE 6 OPTETRAK LOGIC CR FEMORAL COMPONENT, SIZ · Exactech, Inc. · May 31, 2012 - [K140302](/device/K140302.md) — OPTETRAK LOGIC POROUS FEMORAL COMPONENTS · Exactech, Inc. · Jul 30, 2014 - [K160342](/device/K160342.md) — EMPOWR PS Knee System · Encore Medical L.P. · May 19, 2016 - [K160157](/device/K160157.md) — LOSPA Modular Knee System · Corentec Co., Ltd. · Dec 1, 2016 ## Submission Summary (Full Text) {0}------------------------------------------------ Image /page/0/Picture/2 description: The image contains the logo of the U.S. Food and Drug Administration (FDA).
