COPAL® knee moulds are sterile single-use moulds used for the preparation of spacers that are intended as temporary knee replacements as part of two-stage septic joint prosthesis revision.COPAL® knee moulds comprise a tibial component and a femoral component, which together form a bearing and move against one another. They can be used in both the right and the left knee joint. The spacer function provides that after removal of the prosthesis the existing joint space is retained and contraction of the musculature and the surrounding tissues is preventedCOPAL® knee moulds are intended for single use and must not be re-used or resterilised.
A moulding device designed to form an implantable provisional joint prosthesis component out of orthopaedic cement (otherwise known as a cement spacer), which is used in two-stage joint revision typically to treat joint arthroplasty infection. It is filled with prepared antibiotic-containing bone cement which cures into the shape of the prosthesis and is subsequently placed into the joint space until replaced with a revision joint prosthesis. It is typically made of silicone and available in a variety of shapes and sizes for different joint applications. This is a single-use device.
