Metal Temporary Implant for
Infected Knee Joint Revision Surgery
The first stage of treatment in infected knee joint revision
surgery is the most critical. Metic 3D provides high-precision
metal-based temporary implants that combine both
functional performance and antibiotic elution capabilities.
Data-Driven Necessity
Infected joint revision is not an exceptional case.
The rapidly growing market and recurring infection cases highlight
the critical need for accurate and safe temporary implants.

Removal of Infected artifical Knee joint
The initial surgery involves the removal of the existing artificial knee joint along with infected tissue.
Insertion of Temporary Spacer
A metal temporary spacer is inserted into the infected site to maintain structural integrity while administering antibiotics.
6 to 12 Weeks of Monitoring
The infection site is closely monitored for 6 to 12 weeks, with continued antibiotic therapy and assisted mobility.
Revision Surgery
Once the infection is fully resolved, the final surgery is performed to implant a new prosthesis.
Conventional Temporary Spacers
: Not Enough for Infection Control
Bone cement-based temporary spacers fall short of meeting the essential requirements for infection treatment—such as mechanical strength, structural integrity, and antibiotic versatility. These limitations, experienced firsthand by surgeons, can now be addressed through technology.
1. Manually Shaped
Cement Spacers
-
The oldest and most common method.
-
Orthopedic surgeons manually mold the cement during surgery.
-
Inconsistent quality, poor precision, and uneven antibiotic distribution.
2. Mold-Based
Cement Spacers
-
Cement is pre-injected into molds (silicone, metal, etc.) prepared before surgery.
-
High cost of disposable molds.
-
Inherits all the limitations of bone cement (brittleness, antibiotic inflexibility
-
Some are sold as mold-included kits.
3. High-Cost
Imported Spacers
-
Factory-produced cement spacers with embedded antibiotics from global companies.
-
Consistent quality and performance.
-
However: no antibiotic customization, very high cost, and non-reusable.
