Asymmetric, Femoral/Tibia 79, Left Knee Spacer with gentamicin is a temporary implant whose main function is to preserve the articular space during a 2 Stage Revision Arthroplasty. Aids in the treatment of infection that emerged due to the implant of knee prosthesis. Once the patient has finished the specific treatment & no signs of the infection remain, the spacer is removed to be replaced by a definitive new prosthesis. This is a prolonged use implant (maximum intended use period of 180 days)
A prefabricated device made of orthopaedic bone cement [e.g., polymethylmethacrylate (PMMA)], with an appropriate antibiotic, that is temporarily placed into a joint space to function as a carrier for the local delivery of antibiotic drugs and to prevent bone-on-bone contact and contraction of soft-tissue during surgical treatment of an infected joint. The shape and size of the device is modified to fit the joint space. This non-weight-bearing spacer remains in place until the infection clears; it is then removed and replaced with a conventional joint prosthesis. This is a single-use device.
