UNI KROMA®

UNI KROMA® is an anatomical, fixed-bearing, unicompartmental prosthesis.
The tibial component is available in a metal-backed version (cemented or uncemented).
Fitting may be performed using a conventional technique or with custom instrumentation.
The instrumentation is original in that it is HYBRID.

Characteristics and materials

Characteristics :

  • The UNI KROMA® prosthesis is anatomical as it is comprised of a femoral component, a tibial baseplate and an insert which are asymmetrical: Internal Left/External Right or Internal Right/External Left.
  • The femoral component and tibial baseplate are available in 6 sizes.
  • The insert is available in 6 sizes and 4 thicknesses.

Materials :

  • Cemented and cementless femoral component: Cobalt Chrome (CoCr) with dual coating for the cementless version (Titanium spray T40 + HA).
  • Cementless tibial baseplate: Titanium (TA6V) with dual coating (Titanium spray T40 + HA).
  • Cemented tibial baseplate: Cobalt Chrome (CoCr).
  • Insert: Polyethylene.

INSTRUMENTS

The instrumentation is called “hybrid” because it combines metallic parts and disposable polyamide parts (Single Use).

The technique of fitting with tailor-made instrumentation makes it possible to make the tibial cuts AND the distal femoral cut.

All UNI KROMA® instruments are manufactured by One Ortho Medical.
SERF is the exclusive distributor of these instruments.

Indications

The UNI KROMA® prosthesis is an unicompartmental prosthesis which is recommended in the following cases :

  • Primary or secondary isolated osteoarthritis of the internal or external femorotibial compartment of the knee;
  • Isolated necrosis of the internal or external condyle of the knee.

The prosthesis is indicated for patients whose bones have stopped growing.

Contraindications of the UNI KROMA® prosthesis are :

LOCAL :

  • Inflammatory and microcrystalline rheumatoid damage ;
  • Functional deficiencies of the cruciate and/or collateral ligaments ;
  • Excessive fixed flexion or varus deformity ;
  • Arthritic damage in the femoro‑tibial contro-lateral compartment ;
  • Absence of the anterior cruciate ligament ;
  • History of high tibial osteotomy.

GENERAL :

  • Acute and chronic infectious diseases regardless of etiology and location ;
  • Neuromuscular and psychiatric pathologies which can cause the failure of the fixation and postoperative care ;
  • Inadequate or insufficient bone support not allowing proper anchoring of the prosthesis ;
  • Physical activity ;
  • Known allergy to one of the materials of the implant ;
  • Pregnant women.
