COPAL® knee moulds – Moulds for the Preparation of Cement Spacers

COPAL knee moulds – Moulds for the Preparation of Cement Spacers
  • moulds for preparation of temporary bone cement knee spacers

  • limited patient mobility during 2-stage revision surgeries

  • articulation: tibial and femoral component together create an articulating bearing surface

  • high customization: 36 options based on 3 sizes (S, M, L), 6 tibia heights with optional stem

  • trials for intraoperative size determination of spacer prepared with COPAL® knee moulds

Handling video COPAL knee moulds


COPAL® knee moulds are designed to prepare spacers by filling the moulds with bone cement. COPAL® knee moulds are disposable cement spacer moulds indicated for use to mold a temporary total knee replacement (TKR) for skeletally mature patients undergoing a two-stage procedure due to a septic process. The molded temporary knee spacer is indicated for an implantation period of 180 days or less. Because of inherent mechanical limitations of the device material (PALACOS®  R+G bone cement), the molded temporary spacer is only indicated for patients who will consistently use traditional mobility assist devices (e.g. crutches, walkers) throughout the implant period.
