COPAL® knee mould Trials are an accessory device for intraoperative determination of the correct size of spacer made from COPAL® knee moulds (Size S: 5159868, Size M: 5159869, Size L: 5159870). COPAL® knee mould Trials are used for a very short period of time (few minutes) during the first stage of a two-stage exchange revision procedure due to a septic process after thorough debridement and are intended for single use. COPAL® knee mould Trials resemble the spacer made from COPAL® knee moulds in size, shape, and geometry. COPAL® knee mould Trials are easily distinguishable from COPAL® knee mould spacers due to their prominent blue color and the stamping “Do not implant”.
A copy of a final knee revision prosthesis, in the form of combined femoral and tibial components, designed to be used before revision implant surgery to validate the proper size of the permanent prosthesis required by the patient and to ensure its proper orientation and positioning. It is one of a set, or a set, of graduated sizes and is typically made of metal and/or polymer. This is a reusable device.
